H��WYo���+_ Anaerobic composting was traditionally used to compost animal manure and human sewage sludge, but recently is has become more common for some municipal solid waste (MSW) and green waste to be treated in this way (Yvette B etal, 2000). /F4 15 0 R In anaerobic composting the moisture content used will depend upon the method of handling and whether it is carried out in the open or in closed container. Any bin with a tight lid and drainage holes can be used. Performance of two-phase anaerobic high solid digestion 49 Table 19. Unlike aerobic composting, the pilå will not heat up.

Despite these disadvantages, anaerobic composting is the best way to go in some situations: You’re looking to dispose of a one-time load of wet, potentially smelly, or pest-attracting kitchen waste, such as you’d accumulate after a day spent canning fruits or vegetables, cleaning freshly caught fish, or organizing a big social gathering that generates food scraps. Organic matter may be collected in pits and covered with a thick layer of soil and left undisturbed six to eight months. Data on composting and anaerobic treatment should be collected separately, where possible. >> composting process is influenced by factors such as temperature, oxygen supply (i.e. /F3 12 0 R While many people have a basic understanding of the composting process, few people understand its complexity.

Anaerobic composting is a slow process that produces foul-smelling gases, yet requires little maintenance once the pile is constructed.
