Background Plant biomass is an abundant and renewable source of energy rich carbohydrates that can be efficiently converted by microbes into biofuels [1]. Butanol is considered as a second generation biofuel when it is produced from lignocellulosic biomass comprising of agricultural and garden wastes that does not compete with the food supplies [2]. Clostridium acetobutylicum is a gram positive...

background: developing cities like khulna, the third largest metropolitan city in bangladesh, have now begun to confess the environmental and public health risks associated with uncontrolled dumping of solid wastes mainly due to the active participation of non-governmental organizations (ngos) and community-based organizations (cbos) in municipal solid waste (msw) management. methods: a survey ...

Kuhlman, L.R., 1990. Window composting of agricultural and municipal wastes. Eur. Symp. on Integrated Resource Recovery from Municipal Solid Wastes. Resour. Conserv. Recycl., 4: 1 5 1 160. Many wastes are produced from agricultural and municipal facilities that are not suitable for direct land application. Composting these wastes converts them to a humus-containing organic material advantageous...

Co-pyrolysis is an enhanced thermochemical conversion process employed to convert lignocellulosic and plastic materials into more improved liquid, gaseous, solid biofuels. has been used extensively for the manufacturing of liquid biofuels (bio-oil) with little emphasis on syngas production. However, a promising source renewable power generation green chemicals. Production provides opportunity a...

This paper presents a comparison of dry anaerobic digestion reactors fed with differently sorted municipal organic solid wastes. One reactor was fed with source sorted organic wastes and a second reactor was fed with mixed organic wastes consisting of grey wastes, mechanically selected municipal solid wastes and sludge. The two reactors utilised the same process (Valorga) and operational condit...

Construction wastes have become the major source of solid wastes in Hong Kong. Thousands of tonnes of solid wastes are produced every year from construction and demolition activities. Increasing generation of these wastes has caused significant impacts on the environment and aroused growing public concerns. Therefore, the minimization of construction wastes has become a pressing issue. This pap...
