  • Conversion of food waste into hydrogen by thermophilic acidogenesis

    Conversion of food waste into hydrogen by thermophilic acidogenesis was investigated as a function of organic loading rate (OLR), hydraulic retention time (HRT) and pH in a continuous stirred tank reactor. In order to identify hydrogen-producing microorganisms, denaturing gradient gel electrophoresis (DGGE) of the polymerase chain reaction (PCR) – amplified V3 region of 16S rDNA analysis was ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Food Waste Collection Innovations

    As more food waste diversion programs roll out in the residential and commercial sectors, manufacturers and suppliers are responding with new collection and container tools. The weight and moisture content of food waste have led to innovations in equipment design and operation. An increase in residential food waste collection programs — and the need to service curbside carts — are ...

  • 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, ...

  • 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 ...

  • 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 ...

  • Examination of food waste co-digestion to manage the peak in energy demand at wastewater treatment plants

    Many digesters in Germany are not operated at full capacity; this offers the opportunity for co-digestion. Within this research the potentials and limits of a flexible and adapted sludge treatment are examined with a focus on the digestion process with added food waste as co-substrate. In parallel, energy data from a municipal wastewater treatment plant (WWTP) are analysed and lab-scale ...

  • 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 ...

  • Turning waste into power

    Economic, social and environmental factors dictate the necessity to manage waste to a new level. Wastewater plants, landfills, farms and food plants are all the owners of biomass that can be digested to produce biogas and turned into power. Biogas can be burned directly in boilers for heat recovery and used for manufacturing, heating or cooling; this is the simplest method of direct biogas ...

  • Food industry needs to step up on responsible groundwater use

    Californians are all too familiar with what happens when water is not treated as the precious resource it is. But most of us are unaware of the enormous power we have through our day-to-day purchases, social media campaigns and petition drives to push food companies to take more responsibility in protecting global water supplies. Food production, the world’s biggest water user, is a major ...
