Valuable Products From Tannery Wastes

Abstract We proved the viability of enzymatic dechromation technology, proceeding under mild reaction conditions, by the daily capacity of 3 metric tons for processing chrome shavings. The advantage of the enzymatic reaction is producing protein hydrolyzates of relatively good quality and chrome sludge. The quality of both is increased by using organic bases to form an alkaline reaction mixture. ...

Investigation of benefit of using coal wastes in cement production

Waste disposal in coal preparation plants leads to serious environmental problems. These wastes usually contain about 20% carbon, and the composition of the remaining ash is similar to clay. Addition of these wastes to cement clinker raw material utilises carbon as a source of energy. In this investigation, the effect of addition of these waste materials to the raw materials used in cement ...
