The composition of kitchen waste is very complex and it mainly consists of organic matter such as starch, dietary fibre, animal fats and so on. Kitchen waste has high moisture content, as well as a high fat, high salt and high starch content. Kitchen waste is mainly disposed through incineration and composting. Considering kitchen waste is not readily combustible, other fuels need to be mixed in. However, kitchen waste hinder the increase in incinerator temperature and the presence of chlorinated compounds corrodes the fireplace and produces dioxins. In addition, the long-term application of high-salt-content fertilizers made from kitchen waste causes adverse effects on the soil and on plant growth, which restricts the development of kitchen waste composting. Lactic acid is an organic acid that is popularly employed in many fields and is in huge demand. Polylactic acid plastics synthesized from lactic acid are biodegradable, environmentally benign, and have broad applications in the market (Yun ...

Microplastic particles are widely distributed in a variety of ecosystems and can be transferred to predators along a food chain after being ingested by prey. However, how microplastic particles affect prey and predator populations is not fully understood. In this study, using the Lotka-Volterra model, we theoretically investigated predator-prey population dynamics in terms of toxicological response intensity (strength to population growth rate) to microplastic particles, and examined the negative effects on prey feeding ability and predator performance due to microplastic particles. Results of numerical simulations indicate the critical properties of the predator-prey system in response to microplastic particles: (i) predators are more vulnerable than prey under exposure to microplastic particles; (ii) the effect of microplastic particles on prey and predator population growths can be negligible when toxicological response intensities of prey and predator are small; (iii) this system is prey ...

The researchers discovered that larval perch that had access to microplastic particles only ate plastic and ignored their natural food source of free-swimming zooplankton.. Microplastic particles (defined as plastic particles ,5mm in size) originate from large plastic waste products that fragment into smaller pieces, or from manufactured plastics of microscopic size (e.g., microbeads in personal care products). These microscopic waste particles reach oceans via waterways and lakes and accumulate in high concentrations in shallow coastal areas.. Today there is increasing concern that the accumulation of microplastic waste particles could affect the functioning of marine ecosystems, but our knowledge of the impacts of microplastic fragments on marine animals is limited. For the first time, scientists have now been able to show that development of fish is threatened by microplastic pollution.. Fish reared in different concentrations of microplastic particles have reduced hatching rates and display ...
Prince Georges County, Maryland recently introduced a new food waste composting pilot project at their Western Branch yard waste composing facility in Upper Marlboro, Maryland. The county selected Sustainable Generation LLC, the GORE® Cover authorized sales and service provider for North America, to assist them with the largest food waste composting project in the state at 4,500 tons per year. Maryland Environmental Services (MES) is the operator for the Western Branch Composing Facility. The facility has historically accepted yard waste and is now testing the addition of food waste in a one-year pilot involving six batch tests. Each batch will test different ratio mixes of food waste and yard waste with the maximum amount of food waste at 50% by weight. The project is using a three heap SG Mini™ System utilizing GORE® Covers. The system was selected because it uses less space, has low energy consumption, provides better processing and leachate management and reduces the current curing ...

The latest scheme began in August 2011 and involves a partnership approach between Sustainability and Site Services. This new food waste collection system offers all University staff the opportunity to participate in food waste composting collections at work. Over 200 collection points have now been established across the University. Each point has a food waste caddy that is collected by a member of Site Services. To date this has diverted almost 20 tonnes of food waste from landfill, the equivalent of a quarter of a million banana skins.. However, there are other, less obvious, benefits to the scheme, as Site Services Manager Liz Lynch explains: The use of caddies means that fears about composting causing smelly bins have been unfounded. Prompt collection of the caddies makes it easier to control pests and rodents, as there is no longer rotting food waste hanging around in bins - in the past fruit flies and midges attracted to wet tea bags have caused us a problem.. In early 2011, ...
When food is wasted, other resources are wasted as well: water, energy, time, manpower, land, fertilizer, fuel and packaging, as well as money put into growing, preparing, storing, transporting, and cooking the food. A recent study in the UK calculated that hotels throw away over 20% of the the food they purchase, over half of which is avoidable. For every £1 of food costs thrown in the bin, total costs could be £1.5 to £2 when accounting for lost labour, lost energy, and waste collection costs.. Some hotels cut food waste by altering their dining services, choosing à la carte menus over buffets (buffets have a high propensity for food wastage especially in hot climates). Others properties prefer to give away unused food.. Reducing food waste helps you stop wasting money and other resources. Food waste solutions can payback in less than a year and cut avoidable food waste costs by up 60%..

A major problem throughout the world, food waste is an issue that must be addressed not only by all actors in the agri-food chain but also without a silo mentality. To examine this problem, this article considers the interfaces between the stages of the agri-food chain, by emphasizing the interconnectivity of the different links in the chain, and focusing on the interface between retail distribution and consumption. We show that food waste is socially produced through the interactions and practices of the different actors within food systems. The study presented in this article results from a collaboration research project with two organizations involved in the food waste debate. The data analyzed are derived from an online survey of 1026 Quebec consumers and from 14 semi-directed interviews with retail distribution merchants in the Montreal area, Canada. By identifying, describing and analyzing the consumption and commercial and logistical management practices that contribute to food waste, our
Along with the rapid development of edible fungus industry in China, the traditional mode of production giving priority to wood chips will be severely limited, and using agricultural waste distributed widely, having large yield, and containing high content of organic matter to produce edible fungus has good economic and ecological benefit. In this paper, based on the analysis of characteristics of agricultural waste in China, the present situation of application of agricultural waste in the production of edible fungi at home and abroad was introduced, and the main problems existing in production of edible fungi by using agricultural waste in China at the present stage were pointed out. Finally, the development direction of using agricultural waste to cultivate edible fungi was discussed, and some suggestions were put forward, such as improving the theoretical system for using agricultural waste to produce edible fungi, and establishing the standardized technical system for using agricultural waste to

This scientific report answers the following questions: What are the origins and causes of food waste? What actions can be implemented? What are the prospects for the future? Within the framework of the European year on food waste, the Louis Bonduelle Foundation organised events along this theme: the two most recent calls for projects, as well as the 7th edition of the Louis Bonduelle Foundation Reunion, were focused on food waste. Extract: Food waste is a complex process that occurs throughout the entire production chain. In developing countries, over half of all loss and waste occurs upstream, during production, due to ill-adapted agricultural practices, post-harvest operations or during storage and transport; whereas in developed countries, waste and loss are generated towards the end of the chain by consumers, without them even realising it. The reasons for all this waste are mostly behavioural: disorganised food shopping, strict compliance with expiry dates, lack of know-how for cooking ...

In this day and age, everyone should have access to healthy food. Unfortunately, thats not the case in Columbus and Franklin County, Ohio. Nearly one-in-five children in my city of Columbus, Ohio, is food insecure. This mirrors statistics we find across the nation. In 2016, 12.3 percent (15.6 million) of U.S. households were food insecure at some point, according to the United States Department of Agriculture (USDA). Twenty-five percent of Franklin County, Ohio, adults say they dont eat five servings of foods and vegetables each day. While our fellow residents dont have access to nutritious food, we have tons of food entering the food waste system. Food waste makes up 13 percent of our county landfill in Franklin County, Ohio. These trends are consistent across the country. Food waste is estimated to be between 30-40 percent of the food supply, according to USDA. As we all know, food insecurity and lack of access to healthy foods can lead to long-term health consequences. Thirty percent of pre-k

This interview features insights from Brian Roe, Professor and Faculty Lead at The Ohio State Universitys Food Waste Collaborative and Laura Moreno, who received her Ph.D. studying food waste at the University of California, Berkeley.
Microplastics are pieces of plastic debris ,5mm in diameter. They are introduced into the marine environment directly for example via release of small pieces of plastics used as abrasives and indirectly through the fragmentation of larger items. The European Marine Strategy Framework Directive 2008/56/EC (MSFD) regards microplastics as an emerging issue of concern and calls for more data on the quantity, distribution and composition of this debris. This thesis examines the amount, composition and distribution of buoyant microplastic debris in marine waters using different sampling devices and methodologies. To investigate the spatial distribution, abundance and composition of microplastic debris between nearshore and offshore marine subsurface waters a subset of samples from the Continuous Plankton Recorder (CPR) survey were examined. Abundance was generally higher in nearshore coastal waters than the offshore oceanic samples, with the highest mean concentrations observed in the UKs coastal ...

This project aims at evaluating the role of waste water treatment plants (WWTPs) as entrance routes for microplastic particles to the marine environment, and is completed within the scope of the Swedish EPA screening programme 2014. Sampling was done at Långeviksverket in Lysekil, a relatively small WWTP with a load of 14 000 population equivalents (pe), and with effluent water being discharged into the sea. Analyses were performed on microplastic particles collected on a filter with a 300. μm mesh size, both in the actual WWTP (incoming and effluent water, and sewage sludge) and in the recipient water. Background levels of microplastics were obtained by analysing seawater from a location not directly affected by the effluents from Långeviksverket. All the sampling was done during the course of one day.. It is not obvious to give an exact definition of the size of the collected particles, e.g. plastic fibres with a diameter smaller than 300. μm might either be caught on the filter or slip ...
And finally, the standard is meant to be flexible enough to evolve over time, as understanding of food waste, quantification methods, and available data improves.. Sustainable Development Goal 12.3. Food loss and waste has significant economic, social, and environmental consequences. According to the FAO, a third of the food produced in the world is lost while transporting it from where it is produced to where it is eaten, even as 800 million people remain malnourished.. In short, food loss increases hunger. The lost and wasted food also consumes about one quarter of all water used by agriculture and, in terms of land use, uses cropland area the size of China, besides generating about 8 percent of global greenhouse gas emissions.. Target 12.3 of the UN Sustainable Development Goals (SDGs) addresses this he global food challenge by seeking to halve per capita food waste and reduce food losses by 2030.. The FLW Protocol can help steer the movement forward, say UN officials. According to Achim ...

In truth, I have difficulty comprehending the vast scale of landscape, resources, and livelihoods dedicated to growing food for human and livestock consumption. And yet, the United Nations estimates that, at present, one-third of the global food supply is wasted (1.3 billion tons annually). To minimize global emissions from agriculture, a logical first step might be to reduce food waste.. In poor countries, food waste typically occurs pre-distribution: for example, milk, meat, or produce may spoil during transport or due to lack of refrigeration, while rats or other pests may infiltrate granaries. In contrast, in wealthy countries food is primarily wasted post-distribution: stores throw away immense quantities of packaged food that has passed its sell by date, while households dont eat their lettuce before it becomes a soggy puddle in the back of the vegetable drawer.. ...
A day after Republicans reinstituted the use of Styrofoam cups in House cafeterias, Democrats are chiding the choice as an environmental and health debacle.. Rep. Mike Honda, ranking member on the legislative branch Appropriations subcommittee, struck out against the move Tuesday, saying it exposes his staff, colleagues and constituents to “known health risks.”. “We know that these Styrofoam cups ... are connected with human carcinogens,” the California Democrat said in a statement. “To claim these cups are part of a cost-cutting measure is completely disingenuous. In fact, Styrofoam cups will increase costs to our country due to health-related impacts, toxic cleanups, new landfill construction and increased reliance on energy-intensive, oil-based plastics.”. House Administration ranking member Robert Brady said that although for financial reasons he supported nixing the House’s composting program, including the compostable cutlery and plates, Styrofoam ...

Styrofoam is a trademarked brand of closed-cell extruded polystyrene foam (XPS), commonly called Blue Board manufactured as foam continuous building insulation board used in walls, roofs, and foundations as thermal insulation and water barrier. This material is light blue in color and is owned and manufactured by The Dow Chemical Company.[1] In the United States and Canada, the colloquial use of the word styrofoam refers to another material that is usually white in color and made of expanded (not extruded) polystyrene foam (EPS). It is often used in disposable coffee cups and coolers, and as cushioning material in packaging.[1] The trademarked term is used generically although it is a different material from the extruded polystyrene used for Styrofoam insulation. The Styrofoam brand polystyrene foam, which is used for craft applications, can be identified by its roughness and the crunch it makes when cut.[citation needed] Additionally, it is moderately soluble in many organic solvents, ...

WASHINGTON - The U.S. Environmental Protection Agency (EPA) is releasing action plans developed by 20 electric utility facilities with 70 coal ash impoundments, describing the measures the facilities are taking to make their impoundments safer. The action plans are a response to EPAs final assessment reports on the structural integrity of these impoundments that the agency made public last May. Coal ash was brought prominently to national attention in 2008 when an impoundment holding disposed coal ash waste generated by the Tennessee Valley Authority failed, creating a massive spill in Kingston, Tennessee, that released more than 5 million cubic yards of coal ash to the surrounding area and is regarded as one of the worst environmental disasters of its kind in history. Shortly afterwards, EPA began overseeing the cleanup, as well as investigating the structural integrity of impoundments where coal ash waste is stored ...

The influence of thermal pretreatment on degradation properties of organics in kitchen waste (KW) was investigated. The kinetics results showed that thermal pretreatment could enhance the degradation efficiency of crude protein (CP), fat, oil and grease (FOG), volatile solid (VS) and volatile fatty acids (VFA). Thermal pretreatment showed no significant difference in the final concentration of protein but could decrease the FOG degradation potential (7-36%), while increased the lag phase for degradation of protein and FOG respectively by 35-65% and 11-82% compared with untreated KW. Cumulative biogas yield increased linearly and exponentially with the removal efficiency of VS and other organics (CP and FOG) respectively. Additionally, the reduction of CP increased exponentially with FOG removal efficiency. The calculating methods of biogas yield, organics reduction and corresponding appropriate digestion retention based on FOG and CP reduction amount and pretreatment parameters were ...

Story at-a-glance Tests reveal bottled water contains nearly twice as many microplastic particles per liter as tap water. The contamination is thought to originate from the manufacturing process of the bottles and caps. Researchers tested 259 bottles of 11 popular bottled water brands for the presence of microscopic plastic. On average, the bottled water tested contained 325 pieces of microplastic per liter Only 17 of 259 bottles were found to be free of microplastic particles, and none of the brands tested consistently free of plastic contaminants. The worst offender was Nestlé Pure Life, the most contaminated sample of which contained 10,390 particles per liter. In response to these findings, the World Health Organization has vowed to launch a safety review to assess the potential short- and long-term health risks of consuming microplastic in water A report by the U.K. Government Office for Science warns plastic debris littering the worlds oceans - 70 percent of which does not biodegrade - ...

In this study, we showed signs of increased upper airway inflammation and respiratory symptoms in waste collectors compared with controls. The inflammation was shown at the end of the working week by higher concentrations of total cells and IL8 before and after the shift, and higher cross shift cell counts in NAL fluid. No differences between waste collectors and controls were found for IL6, TNFα, and IL1β in NAL fluid. The main types of cells found in the NAL fluid were neutrophils and epithelial cells, whereas eosinophils were only occasionally found, which is indicative for a non-immune inflammation mediated by neutrophils as described previously in the waste industry.5,6 This was furthermore supported by the observed increased levels of IL8, a strong chemoattractant of neutrophils, and by the finding that IgE sensitisation against fungi was rarely found in either waste collectors and controls. Serum IgG antibody titres against fungi and actinomycetes were the same for waste collectors and ...
The aim of this work was preparation and investigation of the polymeric composites from naturally occurring materials with the properties similar to those of conventional polymer composites and which can degrade to harmless substances after use. The other target of this work was to estimate the applicability of industrial waste materials as fillers in the polymeric composites and thus to offer a potential exploitation of biodegradable waste materials as an alternative to disposal. In this study, the polymeric composites were prepared by photopolymerization of glycerol diglycidyl ether and different industrial waste materials (rapeseed cake, phosphogypsum and horn meal) using a mixture of triarylsulfonium hexafluoroantimonates as photoinitiator. The effect of the amount and nature of the industrial waste materials on the kinetics of photopolymerization, values of contact angle and surface free energy, mechanical, thermal, rheological properties, swelling in water and biodegradability of the ...
Despite widespread detection of microplastic pollution in marine environments, data describing microplastic abundance in urban estuaries and microplastic discharge via treated municipal wastewater are limited. This study presents information on abundance, distribution, and composition of microplastic at nine sites in San Francisco Bay, California, USA. Also presented are characterizations of microplastic in final effluent from eight wastewater treatment plants, employing varying treatment technologies, that discharge to the Bay. With an average microplastic abundance of 700,000 particles/km2, Bay surface water appears to have higher microplastic levels than other urban waterbodies sampled in North America. Moreover, treated wastewater from facilities that discharge into the Bay contains considerable microplastic contamination. Facilities employing tertiary filtration did not show lower levels of contamination than those using secondary treatment. As textile-derived fibers were more abundant in ...

Methanol is produced from an organic waste material such as sewage by a process wherein an arc heater or plasma jet performs novel process steps including: (1) partially vaporizing an organic sewage sludge (a semi-liquid material produced by bacterial digestion of the sewage); (2) reacting the gas products obtained by the sludge vaporization, together with a digester gas (obtained by digestion of the sewage), to form a synthesis gas comprising principally H2, CO, CO2, H2 O and CH4, and (3) optionally, driving a water shift reaction to convert a portion of the output gases to additional H2 and CO for use as a feed stream to the jet. The synthesis gas is converted to methanol in a subsequent process step.
About 30-40% of food in the US is wasted, according to USDA, which takes a heavy toll on water consumption and carbon emissions. As consumers grow more conscious about the sustainability and environmental impact of food choices, restaurants and retailers are responding. Chef Jehangir Mehta, owner of NYC restaurants Graffiti Earth and Me & You, is a leading authority on increasing sustainability and reducing food waste in the foodservice sector. Peanuts are a natural fit for sustainability and reducing waste because theyre a zero-waste crop. From water to fertilizer, peanuts require fewer and fewer resources to grow. Nutrient-rich peanut plant hay is tilled back into the soil or fed to livestock. Peanut oil is used in commercial products and as biodiesel. Peanut flour and powder are culinary ingredients packed with nutrition and flavor.. Heres how Chef Mehta advises tackling the challenge of waste in the foodservice industry, and how peanuts can play a role.. ...

Compared to the CO2 emissions of individual countries this volume, which is the estimate produced by the FAOs Food wastage footprint - impacts on natural resources, 2013 ranks third among the worlds biggest greenhouse gas emitters after China and the USA.. What this means in concrete terms is that the greenhouse gas associated with the production, processing, transport and storage of all non-consumed food corresponds to roughly half of what both China and the USA emit into the atmosphere each year, according to SAVE FOOD, a joint initiative of the Food and Agriculture Organisation of the United Nations (FAO) and Messe Düsseldorf GmbH.. For Germany this figure stands at approximately one giga ton - less than one third of all global emissions caused by food loss and waste.. By comparison the with 3.3 giga tons (billion tons) of food waste emissions, the greenhouse gas emissions associated with road traffic in all of the USA was 1.5 giga tons in 2010.. Broken down into food categories, cereals ...
In some places, microplastic is swirling in concentrations greater than at the surface of the infamous Great Pacific Garbage Patch.
Anaerobic digestion is one of the best available technologies for food waste (FW) and pig manure (PM) management by producing methane-rich biogas. However, mono digestion of FW or PM is easily inhibited by high volatile fatty acid (VFA) or ammonia. Co-digestion of FW and PM can provide an effective solution to address these issues due to the buffering interactions between the VFA and ammonia. Compared with wet digestion, dry digestion can reduce the digester volume significantly, thereby decreasing initial capital expenditure and the energy consumption required for heating. In this research, batch dry co-digestion of FW and PM was conducted in laboratory-scale digesters at the total solid (TS) content of 20%. The research objectives were to assess (1) the feasibility and optimal operation conditions of dry co-digestion systems; (2) methane production kinetics and the inhibition mechanisms; (3) the biosafety of digestate, i.e. the inactivation of enteric indicator bacteria, including total ...
Deep Well Injection of Industrial Wastes JOHN C. MANNING, President HydroDevelopment, Inc. Bakersfield, California INTRODUCTION Pollution of the natural environment by waste products has become one of the major problems facing our modem industrial society. Human and industrial wastes have been disposed of traditionally by dumping on the ground or by discharge to streams, lakes, or to the ocean. As quantities of wastes have increased along with growing population and more advanced technology, the natural environment sometimes has been overloaded with waste products. The result is pollution. And the only way to abate the pollution is to reduce the quantities of wastes being discharged or to find new ways or new places to dispose of waste products. With increasing attention being given to pollution abatement in recent years, a number of innovations in waste disposal have been put into practice. One of the most promising of these is the process of waste disposal by deep-well injection. At present ...
Sustainable aviation fuel (SAF) made from food waste has the potential to reduce net carbon emissions by 165% compared to fossil jet fuel, according to researchers at the U.S. National Renewable Energy Laboratory (NREL).
Global solutions for pollution include plogging in Sweden, food waste programs in Denmark, smog-eating buildings in Mexico and Italy, and recycling oil in Canada.
Insects may be a tasty, environmentally-friendly source of protein...but not everybody is excited about chowing down on bugs. So Grubbly Farms is putting edible insects to another use: harvesting black soldier fly larvae for livestock feed. And because they feed the larvae on material that would otherwise wind up in the garbage, the company hopes to reduce food waste as well. At the 2015 Kairos Global Summit, Popular Science host Katie Linendoll caught up with Grubbly Farms cofounder Patrick Pittaluga to get the lowdown on these creepy-crawlies. ...

It also highlights the current application and future potential of agroindustrial waste reinforced composites in aerospace, automotive and other construction industries.. ...
Give thanks - then compost!Since this is Thanksgiving week here in the U.S., a time when we are at our most gluttonous, composting is a timely issue. In fact, Im putting together a video with tips for getting started - keep an eye out for it.. In the meantime, your question is an interesting one. Are yard and food scraps the key to quicker decomposition in landfills? The answer is no. In fact, such organic waste is the bane of a landfill operators existence; it takes up a quarter of the space and is a major source of methane, a greenhouse gas thats twenty times more potent than carbon dioxide. Paper is also a problem: its another major source of methane, and accounts for about a third of our municipal solid waste.. This is why composting and recycling are so important. Here in the U.S., we are better about recovering paper and yard waste than food waste: In 2007, according to the EPA, we recycled 54 percent of our paper and composted 62 percent of yard waste. When it comes to food waste, ...
A fertilizer comprising a dewatered solid agricultural nutrient is disclosed. A method for preparing this fertilizer is provided including the steps of providing a raw agricultural waste to be treated, adding to the raw agricultural waste an effective amount of a composition comprising a quaternized amino methylated polyacrylamide polymer for separating the raw agricultural waste into a mixture having a separate clarified liquid portion and a separate dewatered nutrient solids portion, wherein the separated dewatered nutrient solids portion is a fertilizer, mixing the composition with the raw agricultural waste to facilitate the separation of the raw agricultural waste into the mixture, and subjecting the mixture to at least one mechanical separation means for segregating the separated clarified liquid portion from the fertilizer. An aqueous system comprising water, raw agricultural waste and a composition comprising a quaternized amino methylated polyacrylamide polymer is also disclosed.
Questions arose around the WMEAC office recently about recycling expanded polystyrene, also known as Styrofoam or EPS, via the City of Grand Rapids single stream recycling service. The confusion came about because Styrofoam is one of the items the city explicitly prohibits residents putting in their curbside recycling bins, even though plastic polymers 1-7 are accepted, including polystyrene (#6).. Non-expanded polystyrene is used in a variety of items: protective packaging like CD and DVD cases, laboratory equipment like petri dishes and test tubes, along with disposable items like razors, silverware, cups, and food containers. Expanded Polystyrene is a different form of the material with a foam-like consistency used for packing materials, insulation, and disposable food containers.. I contacted James Hurt, Public Services Director for Grand Rapids, who indicated that since the Kent County Recycling Facility did not accept expanded polystyrene, the the city could not accept it either. Hurt was ...

Prerenal azotemia is common, especially in older adults and in people who are in the hospital.. The kidneys filter the blood. They also make urine to remove waste products. When the amount, or pressure, of blood flow through the kidney drops, filtering of the blood also drops. Or it may not occur at all. Waste products stay in the blood. Little or no urine is made, even though the kidney itself is working.. When nitrogen waste products, such as creatinine and urea, build up in the body, the condition is called azotemia. These waste products act as poisons when they build up. They damage tissues and reduce the ability of the organs to function.. Prerenal azotemia is the most common form of kidney failure in hospitalized people. Any condition that reduces blood flow to the kidney may cause it, including ...
Carbon dioxide (CO2) enrichment of anaerobic digesters (ADs) without hydrogen addition has been demonstrated to provide a potential solution to manage CO2 streams generated in the water and organic waste sectors, with concomitant increases in methane (CH4) production. This study investigates the CO2 utilization mechanisms, by considering chemical and biological pathways in food waste and sewage sludge ADs. Methanosaetaceae was observed to be the dominant methanogen in sewage sludge ADs (Abundance of 83.8-98.8%) but scarce in food waste units (3.5-5.8%). Methanosarcinaceae was dominant in food waste (14.3-32.4%), likely due to a higher tolerance to the free ammonia nitrogen concentration recorded (885 mg L−1). RMethanosaetaceae (ratio of Methanosaetaceae fluorescence signal between test and control) of 1.45 and 1.79 were observed for sludge ADs enriched once and periodically with CO2, respectively (p-value | .05), suggesting a higher Methanosaetaceae activity associated with CO2 enrichment.

You must complete a waste transfer note (WTN) for every load of waste you pass to others. This will include a detailed description of the waste.. You may be able to use a season ticket if you have regular collections of waste of the same type and from the same place, by a waste carrier. This is one transfer note covering a series of transfers over a year, for example weekly collections of waste from shops or commercial premises or multiple lorry trips to remove a large heap of waste. If you use a season ticket you must keep a log of the individual waste transfers.. A WTN shows carriers and site operators who handle your waste what they are handling. WTNs also ensure that there is a clear audit trail for the waste from when it is produced until it is disposed of.. A WTN must be completed and signed by both the person sending the waste and the person collecting it.. Waste holders and transporters must carry the WTN alongside the waste it relates to and must produce the note if stopped by an ...
How do you feel social media is impacting social change communication?. Beka: I get psyched about social media, the sheer number of people that you can communicate with instantaneously is exciting. Its been so crucial in our launch and initial growth. Social media gets a bad rep a lot of the time, but I think the other side of that is that when its used for good, youve got such a powerful tool. Im all about encouraging and celebrating the positive side of it. I hope that Wise Boys can add to that.. It is estimated that avoidable food waste costs New Zealand $870 million annually, the numbers are staggering. As a business how do you guys reduce avoidable food waste?. Tim: Its pretty tough for us. Being a food truck you gamble a lot on how much you might sell each week. Sometimes you nail it but sometimes we have too much left over at the end of the week. Any of our food waste thats a no go is commercially composted by We Compost and sometimes well take some buns to the Auckland City ...
The microbial synthesis of polyhydroxyalkanoates (PHA) from organic wastes is a valuable process to valorize available renewable resources, such as food wastes and biological sludge. Bioplastics find many applications in various sectors, from medical field to food industry. However, persistent organic pollutants could be transferred from wastes to the final product. The present paper demonstrates that the use of municipal wastes in PHA production is safe for the environment and human health and provides a polychlorinated biphenyl (PCB) profile in both commercial and waste-based PHA samples. PCB analysis in several PHA samples showed very low concentrations of the target analytes. Commercial PHA samples showed a similar PCB level with respect to PHA samples from municipal waste/sludge and higher than PHA samples from fruit waste. For all analyzed PCBs, detected concentrations were consistently lower than the ones reported in regulatory framework or guidelines.

The state of Kentucky regulates the operation of municipal garbage dumps but says nothing about the disposal of coal ash, said KFTC member Mary Love. I applaud the EPAs decision to finally set nationwide rules for the disposal of this dangerous waste stream.. The settlement was filed late yesterday in response to a lawsuit brought in 2012 by Earthjustice on behalf of Appalachian Voices (NC); Chesapeake Climate Action Network (MD); Environmental Integrity Project (D.C., PA); Moapa Band of Paiutes (NV); Montana Environmental Information Center; Physicians for Social Responsibility; Prairie Rivers Network (IL); Sierra Club; Southern Alliance for Clean Energy; Western North Carolina Alliance and KFTC.. Threats from coal ash ponds remain for generations. Peak pollution occurs between 78 to 105 years after ash pond operation begins.. In October, the U.S. District Court for the District of Columbia ruled that the EPA has a mandatory duty to review and revise its waste regulations under the Resource ...
In the tiny Montana town of Colstrip, people knew the Moose Lodge well water tasted bad. But it would be years before the community learned why.. Waste ponds at a massive coal plant nearby had leaked over the decades, contaminating wells in residential neighborhoods and groundwater under cattle grazing lands, as lawsuits would eventually allege. According to an excellent investigation last year by The Center for Public Integrity (CPI), some who drank the well water got diarrhea; another resident stopped drinking her strange-looking tap water after her cat would no longer lap it up.. The contamination came from a coal plant, but not from the usual air pollutants. Toxic materials that dont go out the stack-arsenic, cadmium, lead, selenium, mercury-get left behind in ash after the coal is burned. Yet coal ash has been wildly unregulated in some places. Despite containing chemicals linked to cancer, birth defects, stomach ailments, fish kills, and livestock deaths, coal ash has been dumped in ...
The Asian Coal Ash Association was founded to bring together industry, academia, governments, NGOs and other stakeholders in the utilization of coal combustion products. The AsianCAA aims to promote initiatives of a scientific, technical, industrial, environmental, educational and legal nature associated with applications for coal ash produced from Asian coal fired power stations.
University of Alabama chemist Robin Rogers imagines a future where shrimp shells could become more than a smelly seafood byproduct.
On Dec. 22, 2008 a containment pond at TVAs plant in eastern Tennessee failed, spilling more than a billion gallons of coal ash. In the weeks following the disaster, a team of Duke scientists analyzed sediment and water samples collected from the areas of the spill, including locations downstream and upstream on the nearby Emory and Clinch rivers. They found high levels of toxic metals and radioactivity, including 75 parts per million of arsenic, 150 parts per billion of mercury, and eight picocuries per gram of total radium.. As long as the sludge remains wet, risk of exposure via inhalation remains slight - but that risk increases as it dries out. People already suffering from lung disease or infections would be especially susceptible to health problems from airborne coal ash dust.. During the ongoing the cleanup, TVA has worked to prevent the spilled ash from becoming airborne by vacuuming it up, wetting the ash and growing grass on top of it.. The Duke research team has also begun a program ...
Yes. People living near sites used to store ash or sludge from coal-fired plants have a 1 in 50 chance of getting cancer. Coal ash contains, high levels of arsenic, lead, mercury and boron, each of which has been known to cause cancer, neurological and development problems, and other illnesses, according to the first citation. Check out the links for more info, but, in general, coal ash is bad stuff, and will make you sick. The possibility for respiratory issues like asthma, as well, are likely to be high whenever youre talking about major contaminants being in the air.. ...
New tests found water wells with elevated levels of a toxin commonly associated with coal ash in water wells located up to a mile away from a nearby coal ash pond.
A process is disclosed for generating burnable gas by gasifying water- and ballast-containing organic materials, be it coal or garbage. The drying, low temperature carbonization and gasification steps are carried out separately. The heat taken form cooled gasified gas is supplied to the endothermic drying low temperature in low temperature carbonation stages. The low temperature carbonization gas is burned in a melting chamber furnace with air and/or oxygen or oxygen-rich flue gas and the liquid slag is evacuated, whereas the low temperature carbonization coke is blown into the hot combustion gases that leave the melting reactions which take place and give carbon monoxide and hydrogen reduce the carbon is removed from the gasified gas, supplied to the melting chamber furnace and completely burned. The advantage of the invention is that the ashes may be transformed into an elution-resistant granulated building material, in that a tar-free burnable gas is generated and in that oxygen consumption is
