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 ...

The biowaste-programme of the german environ-mental foundation - Results, conclusion and perspectives

The biowaste programme of the German Environmental Foundation was started in 1995. Since its beginning 55 projects were supported with more than 32 Mio DM (ca. 16 Mio EURO) focussing the following sectors: i) development and application of new compost-based products; ii) reduction of pollutants and higher effective pre-sorting of extraneous materials; iii) innovative technologies of biowaste ...

$Perspectives of composting and anaerobic digestion technologies for the treatment of organic fraction of municipal solid waste in Europe and Asia$

Perspectives of composting and anaerobic digestion technologies for the treatment of organic fraction of municipal solid waste in Europe and Asia

The development and implementation level of composting and anaerobic digestion technologies for municipal biowaste management in Europe and Asia are different in many aspects. The progress of these technologies generally depends on the lifestyle, waste generation rate, waste characteristics, awareness level, acceptability, market value and other economic factors. In Europe, regulatory directives ...

Integrated environmental biotechnology-oriented framework for solid waste management and control in Nigeria

Several environmental problems arising from man's activity have to be solved in a cost-effective and an environmentally friendly approach. In this paper, a framework for an integrated management and control of solid waste in the south-east zone of Nigeria is presented. The major activities include collection and transportation of solid waste to designated areas, separation of reusable components ...

Determination of sand content in digestate

The biological treatment of separate collected waste becomes more and more important. The composting is still the dominant method of treating this waste, but the anaerobic alternative, the anaerobic digestion, plays an increasing part. In Germany already 15% of the whole capacity of biological treatment plants for separate collected biowaste are of anaerobic digestion (Kern, 1998), because of its ...

European Experiences With the Treatment and Digestion of Bio-Organic Waste

In the area of waste management environmental awareness has essentially increased and according technologies got more and more accepted in Europe within more than ten years now. During all the time BTA has gathered experiences by developing and realising flexible concepts for biowaste treatment plants of different design and capacities for the treatment of various waste streams: full scale plants ...

Environmental evaluation of systems for the recovery of biogenic wastes

The recovery of waste materials is promoted by the German Waste Act 'Kreislaufwirtschafts- und Abfallgesetz'. It requires that among the recovery routes available for a specific waste category the priority has to be on those which are more environmentally compatible. As a restriction given by the law, only those recovery routes which are technically feasible and economically reasonable must be ...

Managing Compostable Bags At Anaerobic Digestion Plants

The highest and best use for treating residential food waste is through source separation, sending organics first to anaerobic digestion (to capture energy), followed by aerobic composting (to return nutrients to the soil). Sending food waste to anaerobic digestion (AD) facilities requires appropriate tools and planning for capturing high volumes of material with low contamination. Compostable ...

Biochemenergy: a project to turn an urban wastes treatment plant into biorefinery for the production of energy, chemicals and consumer's products with friendly environmental impact

Urban bio-wastes (UBW) contain soluble bio-organics (SBO) with excellent surfactant properties are proven or expected to perform as bio-based products for use in chemical and environmental technology, in agriculture and in animal husbandry as well as or better than commercial synthetic products. On these basis, UBW are proposed as renewable sources of a wide number of products with potential sale ...

Environmental efficiency of composting versus anaerobic digestion of separately collected, organic waste

Environmental policy in the Netherlands among others aims at closing material cycles and minimising the amount of waste requiring final disposal. In this policy the highest priority is given to the prevention of waste production followed by (in descending order of preference) reuse, incineration with energy recovery and sanitary landfilling. In the implementation of this solid waste policy also ...

Reasonable waste digestion plants

During the last years it became quite clear that in the area of utilisation of organic waste the anaerobic digestion has developed a leading position. This is not only based on its well known advantages:- abhigh rate degradation of organics- abcontained process- ablow emissions- abhigh yield of CO2-neutral produced biogas and high quality compost as its productsbut also on the fact that customers ...

Adding AD To Existing Composting Site Footprint

About an hour’s drive west of Munich in southern Germany, the City of Augsburg had been served by an indoor composting facility since 1994. It was operated by Abfallverwertung Augsburg (AVA), three quarters of which was initially owned by the City of Augsburg and the districts of Aichach-Friedberg and Augsburg. Until recently, the remaining quarter was owned by a private company but as of ...

Digester Developer Taps Natural Gas Markets

IN the late 1990s, Dan Eastman and two colleagues were researching business opportunities in the renewable energy industry. They were looking for a commercially viable technology that could take renewable energy from an experimental phase to a solid business investment. In 1999, Eastman and his partners founded Microgy, Inc., with its base in Wisconsin. The company licensed the Xergi anaerobic ...

Anaerobic procedures (fermentation)

Anaerobic technology is particularly well suited for the utilisation of organic industrial refuse with a high water content as well as for the organic part of bio-waste. A crucial factor for the increasing acceptance of anaerobic waste treatment is the fact that - in contrast to composting - the energy (digested gas) which is released during fermentation can be collected and used and enables ...
