In recent years, the disposal of organic wastes from domestic, agricultural and industrial sources has caused increasing environmental concerns. In this regard, the recycling of utilizable waste is feasible. This can be solved by combination of effective technologies like Biodung composting and Vermitech (incorporating earthworms for the production of vermicompost). The present work was carried...

The aquatic environment has always been subjected to different types of pollutants of industrial, domestic and agricultural wastes (Mance, 1987; Kalay and Canli, 2000) which severely affect the aquatic organisms. Beaumont et al., (2000) and Almeida et al., (2001) reported that rapid industrialization in India has resulted into a substantial increase in the liquid waste (spent wash or effluent),...

In this paper, the present status of the industrial waste, development foundation, and research progress of high technology are discussed based on the author’s experience on the development of industrial waste. The important academic and utility values are presented.

the silica gel waste (sgw), after its collection from a local factory (kolkata, india) was modified with cationic surfactant and was utilized as an adsorbing media for the removal of 2,4- dichlorophenoxyacetic acid (2,4-d) from agricultural runoff of a tea garden. characterization of base adsorbent and modified adsorbent was carried out. the efficacy of the adsorbent was evaluated through both ...

A review is given of gasification processes for solid fuels with special emphasis on waste gasification. Although the co-current moeing bed gasifier has not been under consideration for a long time, it offers interesting possibilitiesJor waste gasification. Some operational data are given. Two potential applications are discussed--gasification of agricultural waste (maize cobs) in the rural are...

Background: Plant biomass and agricultural waste products disposal is a serious problem in agriculture based countries. These wastes, usually rich in xylan can be satisfactorily converted to industrially important and useful products by efficient biotechnological application of potent xylanase producing bacteria which generally have high temperature and pH optima....
