Industrial biotechnology processes have recently been exploited for an economic utilization of wastes to produce value added products. Of which, fish waste is one of the rich sources of proteins that can be utilized as low cost substrates for microbial enzyme production. Fish heads, tails, fins, viscera and the chitinous materials make up the wastes from fish industries. Processing these wastes...

This study was designed to evaluate selected chemical and microbiological treatments for the conversion of certain local agro-industrial wastes (rice straw, corn stalks, sawdust, sugar beet waste and sugarcane bagasse) to ethanol. The chemical composition of these feedstocks was determined. Conversion of wastes to free sugars by acid hydrolysis varied from one treatment to another. In single-st...

The exchange of wastes, by-products, and energy among closely situated firms is one of the distinctive features of the applications of industrial ecological principles.This at= ticle examines the industrial district at Kalundborg, Denmark, often labeled as an “industrial ecosystem” or “industrial symbiosis” because ofthe many links among the firms.The forces that led to its evolution and to the...

Optimum conditions for the determination of lanthanum at sub μg level have been developed employing differential pulse polarography. A detection limit of 0.5μg/ml has been achieved. The method successfully been applied for analysis of lanthanum in industrial wastes.

The aim of this study was evaluate the potential use of low-cost and environment friendly solvents to extract polyphenols from apple wastes for biotechnological application. Apples solid wastes from industrial transformation were used as raw material to produce extracts enriched in antioxidant polyphenols, using a green and environmental friendly solvent in a solid-liquid extraction. The reacti...
