Abstract:

The expansion of biofuel production has increased, due to the near depletion of fossil fuels. Substances which were once considered wastes are now being converted into biofuels (e.g. combustion of MSW producing electricity). One such waste in abundant supply is pig manure. The preferred method of disposing manure is land­spreading. The implications of The Nitrates directive (SI 610 2010) [1] has meant that less manure is land spread producing excess manure. Manure has been used to create heat and energy by anaerobic digestion. However, research into the use of manure as a solid fuel is in its infancy. The aim is to assess the suitability of separated solid pig manure (SRM) composted neat and co­composted over 56 days with various biomass addendums as a potential biofuel. It is found that during composting the ratio of inorganic/organic species altered, leading to an increase in ash and decrease in GCV. As the organic fraction decreased, the inorganic fraction increased causing a concentration of metals. Analysis showed that SRM and sawdust and SRM and woodchip samples with minimum composting time had the most suitable results. However, an allied study found that 7 days composting was required for removal of pathogens.
