“…This confirmed the need for either an insulating layer of compost, peat or other suitable material (Rynk 1992), or an impermeable barrier, in further trials. The extent of the thermophilic periods in both manure/amendment/woodchips trials compared to 40-70 days found by Cooperbrand & Middleton (1996) for a field scale passively aerated system treating poultry litter and municipal solid waste.…”

“…The microbial respiratory activity in compost samples was measured based on CO 2 -C evolution rate conducted in closed bottles according to Öhlinger [15] and Alef [16] soil respiration techniques, but with some modifications made to techniques based on similar soil respiration procedures reported in literature [17][18][19][20][21]. CO 2 -C was trapped in an alkaline solution (KOH), which was then titrated with HCl.…”

a b s t r a c tFaecal Sludge (FS) contains high concentrations of pathogenic microorganisms that are 10-100 times higher than those in domestic wastewater. Proper and sustainable treatment is required to inactivate these pathogens if FS is to be recycled in agriculture, so as to minimise public health and environmental risks. Composting is one of the common low-cost technologies of sanitising FS in Urban Africa; however, it is associated with longer pathogen inactivation periods that make it commercially uneconomical. This study investigated the effect of different organic wastes types and their mixing ratios with FS on the inactivation efficiency of viable Ascaris eggs (suum and lumbricoides) during composting. Dewatered FS was mixed with market waste (MW), chicken feathers (CF) and sawdust (SD) in different ratios. Compost piles of FS:MW:SD and FS:CF:SD both in volumetric ratios of 1:2:1 and 1:3:1 were set-up in duplicate (3 m 3 each), composted and monitored weekly for viable Ascaris eggs presence for a period of 15 weeks. The results suggest that the organic waste types have a significant effect on the temperature evolution and pathogen inactivation efficiency while their mixing ratios do not. Piles containing CF achieved the shortest pathogen survival period of 4 weeks compared with 6-8 weeks for those with MW. The temperature-time factor was found to be the most important variable responsible for viable Ascaris eggs inactivation. However, other mechanisms such as microbial antagonism or antibiotic action induced by indigenous microorganisms and toxic by-products such as free ammonia were found to have also played an important role in Ascaris eggs inactivation. All piles attained 100% Ascaris eggs inactivation from FS, and therefore, the compost was safe for use in agriculture. The study findings suggest that composting of FS with CF can reduce Ascaris eggs inactivation periods by 42%, which may thus reduce the operational costs of FS treatment facilities.

“…On the other hand, nutrient loss is an unavoidable problem during the composting of organic waste. This is especially the case for nitrogen, the most essential fertilizer nutrient for crop production in many situations (Cooperband and Middleton 1996;Rao Bhamidimarri and Pandey 1996). According to previous research, total nitrogen (TN) loss during the course of composting organic waste ranged from 16% to 76% (Barrington et al 2002;Raviv et al 2002).…”
