Abstract
Composting of raw organic waste is an excellent example of highly biological processes used for agricultural practices. The Open pile and the Windrow methods where used in composting poultry, cow and Municipal solid waste for 12 weeks and the heavy metals in the finished products where determined using the Atomic Absorption Spectrophotometer. The results showed a steady decline in the first seven weeks of composting and the overall quality of the final compost meet the recommended standard by the European Union for finished compost. Large scale, wide spread and further researches are highly recommended.
Highlights
Composting transforms organic matter into a stable product of humus-like substance
Comparing the mean of counts, the results showed the mean values for the total pate counts and the total coliform counts, there is a significant reduction in counts between the weeks (p
The results for the two types of composting techniques used revealed a steady decline in the mean count for total plate and total coliform count up to week 9 and week 8, respectively (Table 2)
Summary
Composting transforms organic matter into a stable product of humus-like substance. Gastrointestinal infections are the most common disease caused by enteric bacteria. Some examples are Salmonellosis, Vibriosis, Shigellosis and other infections caused by Campylobacter jejuni, Yersinia sp and E. coli 0157: H7 and many other strains. Wichuk and McCartney (2007) advised that since the infective dose for many of these organisms is very low, it is generally accepted that pathogens should be reduced to non-detectable levels and that compost should be maintain at 55°C for at least three days. It has been reported that Campylobacter in cattle manure can survive composting and persist for a long period in the final product (Inglis et al, 2010)
