Different Indices to Express Biodegradability in Organic Solid Wastes

The composting potential of different organic solid wastes: experience from the island of Crete.

For the past 20 years, the National Foundation for Agricultural Research in Crete and the School of Agricultural Technology of the Technological and Educational Institute of Crete have been involved in a number of research and development activities, related to the production and evaluation of compost derived from a variety of local solid, mainly agricultural organic wastes. Materials such as o...

Emission of volatile organic compounds from composting of different solid wastes: abatement by biofiltration.

Emission of volatile organic compounds (VOCs) produced during composting of different organic wastes (source-selected organic fraction of municipal solid wastes (OFMSW), raw sludge (RS) and anaerobically digested wastewater sludge (ADS) and animal by-products (AP)) and its subsequent biofiltration have been studied. Composting was performed in a laboratory scale composting plant (30l) and the e...

Growth and reproduction of Perionyx excavatus in different organic wastes

Earthworms have been successfully used in the vermistabilization of urban, industrial and agricultural wastes in order to produce organic fertilizers and obtain protein for animal feed. Although many species could be used for these ends, given their nutritional requirements and reproductive biology, only Perionyx excavatus and Lampito mauritii are widely used. The most effective use of earthwor...

Solid-phase Methane Fermentation of Solid Wastes

Dr. Ghosh has presented a novel technique for the con­ version of Municipal Waste (MSW) to methane rich gas. Prior work has either permitted fermentation to proceed naturally (landfill gas extraction) or used conventional stirred reactors (DOE Ref COM facility). Proposed is to recycle leachate through a mass of solid waste to achieve volatile acids and then to convert the acids to methane in a ...
