Impact of food industrial waste on anaerobic co-digestion of sewage sludge and pig manure
(2004) In Journal of Environmental Management 70(2). p.101-107- Abstract
- The performance of an anaerobic digestion process is much dependent on the type and the composition of the material to be digested. The effects on the degradation process of co-digesting different types of waste were examined in two laboratory-scale studies. In the first investigation, sewage sludge was co-digested with industrial waste from potato processing. The co-digestion resulted in a low buffered system and when the fraction of starch-rich waste was increased, the result was a more sensitive process, with process overload occurring at a lower organic loading rate (OLR). In the second investigation, pig manure, slaughterhouse waste, vegetable waste and various kinds of industrial waste were digested. This resulted in a highly... (More)

Although the conversion of volatile fatty acids was incomplete the processes worked well with high gas yields, 0.8-1.0 m(3) kg(-1) VS. (C) 2004 Elsevier Ltd. All rights reserved. (Less)
