  • Coalition “Feeds The Need” In California County

    The Waste Not Orange County Coalition is a public-private partnership that increases the flow of — and access to — wholesome nutrition for food-insecure families. Dr. Eric Handler is a pediatrician — and the Public Health Officer for Orange County, California. Over four years ago, he was attending a meeting in Sacramento, the state capital, and met Mark Lowry, Director ...

  • How Food Waste Costs Our Cities Millions

    It would take farm land the size of Mexico just to grow the amount of food that humans produce, but do not eat, every year. More food goes uneaten at the consumption phase of the supply chain—in places like homes, restaurants and cafeterias—than at any other stage. Almost all urban areas experience high levels of food waste—food that is fit for consumption when it reaches ...

  • Effect of operational pH on biohydrogen production from food waste using anaerobic batch reactors

    This study was performed to investigate the influence of operational pH on dark H2 fermentation of food waste by employing anaerobic batch reactors. The highest maximum H2 yield was 1.63 mol H2/mol hexoseadded at operational pH 5.3, whereas the lowest maximum H2 yield was 0.88 mol H2/mol hexoseadded at operational pH 7.0. With ...

  • The Global Food Challenge Explained in 18 Graphics

    The world is projected to hold a whopping 9.6 billion people by 2050. Figuring out how to feed all these people—while also advancing rural development, reducing greenhouse gas emissions, and protecting valuable ecosystems—is one of the greatest challenges of our era. So what’s causing the global food challenge, and how can the world solve it? We begin to answer these questions ...

  • High density polyethylene (HDPE) pyrolysis plant

    Thermal degradation of plastic polymers is becoming an increasingly important method for the conversion of plastic materials into valuable chemicals and oil products. In this work, virgin high-density polyethylene (HDPE) was chosen as a material for pyrolysis. A simple pyrolysis reactor system has been used to pyrolyse virgin HDPE with an objective to optimize the liquid product yield at a ...

  • Emerging Waste Conversion Technologies

    Today, people and companies are more aware and concerned about the environment than ever before. Everyone is looking for ways to reduce waste or convert organic waste into something more useful. The Federal Government has introduced a renewable energy policy and is continuing to fund for new waste conversion technology. It is now important for local governments to portray their cities and towns ...

  • Marketing and implementing emerging waste conversion technologies: the local effect

    Solid waste management in the U.S. has always been a uniquely local endeavor. Typically, landfilling has provided the most efficient and least expensive option for solid waste management by local governments. Recently, there has been an increasing demand for clean, affordable alternatives to landfilling and other traditional forms of waste disposal. Throughout the world, mainly in Europe and ...

  • Release behaviour of chromium from ferrochrome slag

    Huge amount of ferrochrome slag, a solid waste is being generated from submerged electric arc furnace during manufacturing of ferrochrome alloy. The waste slag contains about 6–12% chromium as chromium oxide and it has the potentiality of releasing hazardous chromium compounds. Although chromium exists in the slag as highly immobile Cr (III) state, there is possibility of chromium release under ...

  • Leveraging microgrids in waste-to-energy applications

    What do the waste-to-energy and real estate sectors have in common? In both, location is the key factor influencing the bottom line. Although waste-to-energy conversion technologies continue to improve their efficiency, energy will always be worth more when it is in the right location. With rising energy costs and increasing concern over electric power reliability and sustainability, the ...

  • Renewable energy from food wastes

    Food waste is an untapped energy source that mostly ends up rotting in landfills, thereby releasing greenhouse gases into the atmosphere. Food waste is difficult to treat or recycle since it contains high levels of sodium salt and moisture, and is mixed with other waste during collection. Major generators of food wastes include hotels, restaurants, supermarkets, residential blocks, cafeterias, ...

  • Removal of benzene from wastewater via Fenton pre-treatment followed by enzyme catalyzed polymerization

    This study investigated the feasibility of a two-step process for the removal of benzene from buffered synthetic wastewater. Benzene is outside the scope of enzymatic removal. In order to remove it from wastewater using enzyme, its pretreatment by modified Fenton reaction was employed to generate the corresponding phenolic compounds. In the first phase, the optimum pH, H2O2 and Fe2+ ...

  • Carbon offsets from organic waste conversion projects

    The Climate Act ion Reserve (the Reserve) has long had a protocol to give credit for the capture and destruction of methane emissions from organic waste in landfills, but they have now opened up the possibility of credits for projects that prevent that waste from entering landfills in the first place. In October 2009, the Reserve adopted the Organic Waste Digestion Project Protocol, covering both ...

  • Case Study - Brett Aggregates adopt MP5 for sustainability

    The Brett Group (http://www.brett.co.uk/) was established in the UK in 1909. Since that time Brett has evolved into a successful, established construction and building materials group - one of the largest independents in the UK. The business is structured into a number of divisions each being aligned with a product set – aggregates, concrete, construction, granite products, ...

  • Decontamination of a natural multicomponent aqueous liquid waste by titania photocatalysis

    The aerobic photocatalytic degradation of municipal dump-site leachate at 300 K has been carried out in a pilot-scale bubble column reactor. The leachate feed is a complex mixture of various organics and nitrogenous compounds. Runs were performed over a 48-hour period at atmospheric pressure. Compositional analysis of aliquots from the reactor revealed simultaneous total organic carbon removal ...

  • Influence of poly(bisphenol A carbonate) and poly(ethylene terephthalate) on poly(vinyl chloride) dehydrochlorination

    Abstract  Recycling of poly(vinyl chloride) (PVC) waste is a serious problem because of its high chlorine content. Dehydrochlorination of PVC-containing polymer waste produces solid residue char, for which conversion to pyrolysis oil in a petrochemical plant seems to be an attractive way of recycling PVC waste. Unfortunately, some polymer admixtures react with HCl and cause formation of ...

  • Workshop Proceedings: QUOVADIS Waste-to-Fuel Conversion? A Thinkshop

    Waste incineration practices are currently being diversified and optimised in terms of the efficiency of the recovery of the energy embedded in the waste. One of these tendencies is the conversion of non-hazardous waste into an adequate form for utilisation in an efficient combustion process. The fact that Directive 2000/76/EC on the incineration of waste (WID) now covers both incineration and ...


  • Recycling; Segregation of Waste; Use of Recycled Products; Energy Conservation: Flinders Medical Centre

     Background Flinders Medical Centre (FMC) initiated the Healthy Environment Project in December 1991 with the aim of minimising waste and exploring other environmental initiatives. FMC is a public teaching hospital in the southern suburbs of Adelaide, with 500 beds and 3,000 staff. Over the past two decades, hospitals have increasingly sought to minimise the risk of ...
