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. ...

Oceans apart: Comparative liability standards on when a product becomes a waste

In the last year the highest courts in Europe and the United States have reached divergent results on the scope of liability of a producer whose product ends up becoming a “waste” by the actions of a third-party. One court held that a producer is not responsible for the third-party actions resulting in contamination unless the disposal was part of the arrangement between them. The other held that ...

On the pre–treatment of municipal organic waste towards fuel production: a review

Lignocelluloses are the main constituents of municipal organic waste (MOW). In order to increase the production of fuels, via fermentations, the enzymatic hydrolysis is the first step towards a valorisation process. It is well–known that the hydrolysis of lignocelluloses is not very effective because of the high stability of the constituents. In this respect the pre–treatment of MOW is necessary ...

Anaerobic fermentation of organic solid wastes: volatile fatty acid production and separation

Anaerobic fermentation of organic municipal solid waste was investigated using a leach-bed reactor (LBR) to assess the volatile fatty acid (VFA) production efficiency. The leachate recycle rate in the LBR affected the VFA composition of the leachate. A six-fold increase in the recycle rate resulted in an increase of the acetic acid fraction of leachate from 24.7 to 43.0%. The separation ...

Going Further with Food: The Rise of Channelling Food Waste for Biogas Production

Almost 50% of the total amount of food thrown away in the UK comes from our homes, representing over seven million tonnes of food and drink wasted from British households annually. Wasting this food costs the average household £470 a year. In fact, if we all stop wasting food that could have been eaten, the benefit to the planet would be the equivalent of taking 1 in 4 cars off the road ...
