  • Global food security is a moral imperative

    We must work to overcome hunger not only for economic and political reasons, but also because it is the right thing to do. It is peculiar to live in a world where hunger is an endemic problem for half the planet while diet books are best sellers in the other half. This point is often lost in the broader bundle of jargon that now defines the conversation on food security in the ...

  • 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 ...

  • Bio-conversion of organic waste using composting technologies – a review

    Composting is nowadays evolving as a highly technical process for processing organic waste separately replacing landfilling along with municipal solid waste. Vegetable waste with high organic content can be composted to produce nutrient rich material that can work as soil conditioner instead of dumping in open landfills. Various studies reveal that due to high organic content of vegetable waste ...

  • Conversion of solid organic waste into compost using Trichoderma spp. and its application on some selected vegetables

    This study was conducted to evaluate the potentiality of Trichoderma species as a bio-conversion agent for composting of solid organic waste and examine the effects of produced composts on the growth of two types of vegetables. The experiments were conducted both in vitro and in vivo processes. In vitro conversion of solid organic waste, the highest height and weight losses were found 42.64 ...

  • 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 ...

  • Biowaste conversion technology for household food and energy security in the Philippines: appropriate on–site small–scale rice husk waste carbonisation

    Successful long–term domestic rice research to feed the rapidly increasing population in the Philippines facilitated increased production of the nation's staple from 11.786 MT in 1999 to 16.258 MT in 2008. The additional rice production has correspondingly increased the annual milled rice husk waste resource to around 3.4 MT - currently, a disposal problem for millers who often dump the waste in ...

  • 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 ...

  • Thermodynamic and exergy efficiencies of magnetocaloric energy conversion utilising industrial waste heat

    An investigation under which conditions industrial waste heat utilised with magnetic energy conversion machines can be a possible alternative to conventional energy conversion technologies is presented. The application of a numerical model leads to the thermodynamic efficiency, the exergy efficiency, and approximate values of the total mass and the total volume of a magnetic energy conversion ...

  • 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+ ...

  • Exergetic performance assessment of gasification and pyrolysis processes of pre-treated wood board wastes

    This paper investigates exergetic performance of gasification and pyrolysis processes and compares their exergy efficiencies, using the experimental data on a two-step process of thermo-chemical conversion of Wood Board (WB) wastes. The exergy values of biomass samples change from 17.49 MJ/kg to 24.57 MJ/kg, respectively. Hydrogen produced from pyrolysis step of gasification varies between 17 ...

  • Waste-to-energy: Garbage to gold: putting waste conversion at the center of the clean fuel market

    As the U.S. explores new technologies to transform our energy supply and reduce our dependence on foreign oil, one of the most exciting clean energy solutions has the potential to transform the waste handling industry as well. Cellulosic ethanol, a clean burning advanced biofuel, can be derived from a wide variety of renewable, nonfood sources, including municipal solid waste (MSW) and ...

  • 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 ...
