Cellulose is one of the most abundant non-degradable organic compound on earth. Near about half of the municipal and agricultural solid wastes contain cellulose or their derivatives. Saccharification or enzymatic hydrolysis of cellulosic wastes liberates glucose. In the present work, cellulase from Cellulomonas uda was extracted, partially purified by dialysis and immobilized on an organic supp...

Anaerobic digestion of dairy cow manure (CM), the organic fraction of municipal solid waste (OFMSW), and cotton gin waste (CGW) was investigated with a two-phase pilot-scale anaerobic digestion (AD) system. The OFMSW and CM were digested as single wastes and as combined wastes. The single waste digestion of CM resulted in 62m3 methane/ton of CM on dry weight basis. The single waste digestion of...

The objective of the German government’s policy on waste is to achieve a recyclingbased economy that conserves resources and reduces adverse impacts on the environment. The aim is to increase and optimise the efficient use of raw materials, to maximise recovery quotas and to permanently remove from our environment any residual waste that can no longer be used. This will lead to a substance mana...

The environmental loading of steroid hormones contained in dairy wastes may cause an adverse effect on aquatic species. To better assess the potential risks of hormone contamination resulting from land application of dairy wastes, various steroid hormones were determined in a typical dairy waste disposal system. Quantitative methods using gas chromatography/mass spectrometry (GC/MS) were develo...
