Industrial wastes are of great interest as a substrate in production of value-added products to reduce cost, while managing the waste economically and environmentally. Bio-ethanol production from industrial wastes has gained attention because of its abundance, availability, and rich carbon and nitrogen content. In this study, industrial potato waste was used as a carbon source and a medium was ...

Red mud, one of the mostly produced industrial wastes, was converted into a catalyst with exceptionally high and stable performance for hydrogen production from ammonia. Results showed that iron species produced after reduction of the HCl digested red mud were converted into ε-Fe2N during the induction period of ammonia decomposition reaction at 700 °C. The catalytic performance measurements in...

Besides their traditional food usage, mushrooms can be used as a source of many pharmacologically active compounds, especially polysaccharides. Wastes left over in the edible mushroom farms such as Agaricus bisporus (white button mushroom) can also become free and alternative source of chitin-chitosan materials, beside the traditional industrial source shellfish waste materials. Chitosan, a nat...

The first industrial revolution has led to a world-wide emphasis on the adoption of industrialisation as the quickest route for rapid economic development. This has forced large-scale import of technologies – both poor and moderate in quality by the developing countries (Maudgal, 1998). All industrial production processes depend upon natural resources for both inputs (source) and disposal of wa...

Developing an understanding of Industrial Ecology (IE) and implementing Design for Environment (DfE) requires a sophisticated understanding of waste streams and the processes and products that generate them. Data deficiencies and methodological issues complicate this necessary effort. Allen demonstrates how data on industrial and municipal wastes can be used to assess the potential utility of w...

A survey of industrial pollution was carried out in Anambra State of Nigeria between February 1992 and June 1993. The survey showed that Idemili, Onitsha and Nnewi Local Government Areas have the greatest concentration of industries in the state and stand a high risk of industrial pollution unless steps are taken to put the issue of waste disposal under strick check. Some of the industries in t...

The all-trans-β-carotene is a natural pigment used in various industrial fields (food, cosmetics, pharmaceuticals, etc) and possesses the higher provitamin A activity, in respect to other carotenoids. All-trans-β-carotene is produced industrially by chemical and biotechnological means. For β-carotene biotechnological production in industrial scale mated cultures of Blakeslea trispora, a heterot...

The UASB Reactor concept represents a very promising proposition for the anaerobic treatment of a variety of industrial wastes and even of domestic wastes. In the present study, after careful acclimatization, the granules were found to be well adapted to fish processing effluent and the COD reduction was upto 96% at organic loading rates from 150 mg l–1 d–1 to 2,200 mg l–1 d-1. The biogas produ...

The present paper discusses sintered glass–ceramics with attractive appearance, which are obtained by vitrification of hazardous industrial wastes. The chemical durability of parent wastes and resulting glasses was characterised by toxic characteristics leaching procedure (TCLP). The crystallisation behaviour was evaluated by DTA and XRD, while the structure of materials was observed by optical...
