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 ...

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 ...
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%..

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
Whats the psychology behind food waste and what can we do to change our behavior? 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 - ...

Dominion has narrowed its differences with environmental groups over how to dispose of coal ash, but the conflict is not easily resolved, and uncertainty about the final outcome prevails.. by James A. Bacon. Dominion Virginia Power has settled disagreements with two foes over its plans to discharge coal ash wastewater from its Possum Point and Bremo power stations into Virginias rivers and streams, but the battle over coal ash disposal isnt going away. Not only are the state of Maryland and the Potomac Riverkeeper Network appealing the wastewater-discharge permit for Possum Point, but Dominion still must acquire solid-waste permits for both plants.. Also, within the next year or so, Dominion will file permit applications for its legacy coal ash ponds at Chesterfield Power Station, while Appalachian Power Co. plans to close and cap an ash pond at its Clinch River Power Station. Determined to hold the power companies to the strictest standards possible, environmentalists have vowed to scrutinize ...
Just as in humans ,a cats kidneys do the important work of filtering waste products from the blood stream.. When kidneys are failing or have failed, waste products can build up. Fortunately, feline kidney disease can be managed.. If your veterinarian suspects feline kidney disease, he will perform tests to measure the levels of BUN (blood urea nitrogen) and creatinine in your cats blood. BUN is a waste product that is produced when protein breaks down as part of the digestive process.. When the kidneys cannot filter this waste product out, blood levels of BUN become elevated.. BUN levels can also rise if your cat is dehydrated, so an elevated BUN level by itself is not enough to make a complete diagnosis.Creatinine is another waste product that is filtered out of the blood by healthy kidneys.. Elevated blood creatinine levels are more diagnostic of kidney disease. Sometimes your veterinarian will compare the levels of creatinine in your cats blood to that of his urine.. If your cat is ...

With global production of plastic exceeding 280 metric tons every year, a fair amount of the stuff is bound to make its way to the natural environment. However, until now researchers havent known whether ingested plastic transfers chemical additives or pollutants to wildlife. A new study conducted by an NCEAS researcher shows that toxic concentrations of pollutants and additives enter the tissue of animals that have eaten microplastic. The findings are published today in Current Biology.. There were two primary objectives for the study: to look at whether chemicals from microplastic move into the tissues of organisms; and to determine any impacts on the health and the functions that sustain biodiversity. Lab experiments exposed lugworms (Arenicola marina) to sand with 5 percent microplastic (polyvinylchloride) that also contained common chemical pollutants (nonylphenol, phenanthrene) and additives (Triclosan, PBDE-47). Results showed that pollutants and additives from ingested microplastic were ...
WMU Dining Services is trayless in all of our dining centers. The trayless initiative began in 2008. Based on food waste audits conducted in 2008, food waste was reduced by up to 30% when trays were removed. In addition to reducing food waste, there are also environmental savings that result from the decreased dish washing volume when trays are no longer used. Fewer cleaning chemicals are used, less energy is consumed to run dish machines, and there is less water waste. WMU students are applauded for their leadership in the national move to trayless dining and their immediate acceptance of this service style.. In conjunction with the Western Student Association, Dining Services helps to raise awareness about the facts regarding food waste to students and other patrons of the dining centers. These infographics about the quantity of food we waste as a society are posted in the dining halls and throughout campus on digital displays. Students and other diners are encouraged to reduce their own ...
Starch saccharified glucose from food waste is an important precursor for a variety of renewable chemicals and fuels. Despite numerous studies on hydrolysis of biomass, detailed kinetic studies and associated models of hydrolysis are lacking. We investigated the kinetics of glycosidic bonds scission of malto-oligosaccharides in lithium bromide molten salt hydrate (MSH) medium and estimated rate parameters from experimental data. We find that the terminal non-reducing bonds hydrolyze faster than the other C-O bonds. Next, we extended the model to simulate the hydrolysis of linear and cyclic saccharides of various degree of polymerization and amorphous potato starch. The model is in excellent agreement with the experimentally determined concentrations for glucose and other oligosaccharides. The chain length of polysaccharides was found to be directly related to their hydrolysis rates ...
