The benefits of composting have been well documented. Reduced volumes up to 60%, lower handling costs, reduction in odour, destruction of weed seeds, destruction of pathogens and a greater degree of public acceptance potentally make it a viable alternative. However, many large previously established operations are based on liquid manure handling systems, therefore would require retrofitting of their current operation. Before considering composting considerations for composting hog manure should be taken into account alog with the specific compost standard that one is trying to achieve.
