  • Green Green Grass

    A few years ago the North Sea managed a twelve month period without any major shipping disasters. Good news for the environment you’d have thought. However, in the same period up to one hundred thousand tonnes of oil were estimated to have been released into the sea. Some of this can be put down to natural occurrence, but by far the major part is dispersed from aircraft and shipping fleets ...

  • Energy Recovery from Residual Waste by Means of Anaerobic Digestion Technologies

    ABSTRACT Anaerobic digestion (AD) is a natural process, spontaneously taking place in natural surroundings, such as marshes,bogs, paddies, or in cesspits, landfills, and dedicated digesters, used for the conversion of organic waste into a rich gas. Typical AD substrates are: manure, sewage sludge, high BOD wastewater, and – more recently - the organic fraction of Municipal Solid Waste (MSW), ...

Engler, Ph.D., ...

  • Evaluating Food Digestion Effluent For Landscape Use

    Over the last year, Loyola Marymount University (LMU) has installed and studied a food waste diversion technology that converts raw food waste into a liquid effluent that is disposed through the sewer system. As an urban university located in West Los Angeles, California, LMU faces two major barriers with respect to composting food waste: on-campus space constraints and long distances to off-site ...

  • Toronto moves forward with anaerobic digestion of residential SSO

    In June 2007, Toronto's City Council approved the “Target 70” plan to achieve 70 percent diversion by 2010. Target 70 includes construction of two, 55,000 metric tons/year anaerobic digestion plants to process residential source separated organics (SSO). City Council says that the digester facilities, along with adoption of single stream recycling and a pay-as-you-throw funding system, will ...

  • Autogenerative high pressure digestion: anaerobic digestion and biogas upgrading in a single step reactor system

    Conventional anaerobic digestion is a widely applied technology to produce biogas from organic wastes and residues. The biogas calorific value depends on the CH4 content which generally ranges between 55 and 65%. Biogas upgrading to so-called ‘green gas’, with natural gas quality, generally proceeds with add-on technologies, applicable only for biogas flows >100 m3/h. In the concept of ...

  • Effects of the anaerobic biowaste treatment processes Management on the digestate quality (residues from Digestion/compost, process water/wastewater)

    Regarding the municipally-collected biowaste amount in Germany, a quantity of 90 - 100 kg/ per annum per citizen is registered (Gallenkemper and Doedens, 1994). That results in an annual biowaste amount of 6.3 to 7 million tons in the Federal Republic of Germany (FRG), whereby also sewage sludges and biogenic, industrial wastes are added. According to Hochrein (1994) about 3 million tons of ...

  • Producing green energy from post-consumer solid food wastes at a wastewater treatment plant using an innovative new process

    ABSTRACT More than 246 million tons of municipal solid waste (MSW) was generated in the United States in 2005, and this tonnage is expected to increase every year. The third highest component of MSW is food waste, but less than 3% of food waste is recycled. In an effort to meet the U.S. Environmental Protection Agency’s national 35% MSW recycling goal, and many states’ and local governments’ ...

  • Women in waste

    The current climate can not be described as prosperous whatever the profession that you are in. It is not a way of ‘living’ but merely a means of ‘surviving’. This has never been more accurate than for the women in waste. The name Jane is defined as one of the many feminine forms of John whereas John is defined as an English masculine name. In the workplace in many industries today, focussing on ...
