Anaerobic Digestion and Composting

14.26 Anaerobic digestion and composting can be an important means of securing the re-use of the organic element of waste that can be used as a substitute for peat. Anaerobic digestion is the bacterial fermentation of organic waste in warm, oxygen-free conditions. The process converts the waste into methane and carbon dioxide and leaves liquid and solid residue. The liquid is a nitrogen rich fertiliser and the solids are used as a soil conditioner. The methane gas can be used to produce heat and electricity. At the present time, digestion plants, particularly for household waste, are not common in the UK. However, in the future the process may become more cost effective and more widespread. Digestion plants for household waste are likely to be large industrial plants and as such must be sited in industrial areas or close to wastewater treatment plants, landfill or waste transfer sites.

14.27 Composting is a process that stimulates the decaying of organic materials by aerobic means. It is usually undertaken on green waste, but it can also be used on mixed household waste. The green waste is normally shredded and heaped in rows (windrows) and turned regularly. Composting of mixed household waste may be undertaken in an enclosed industrial type building where the compost is processed, including aeration and mechanical means of turning, and would generally be undertaken in an industrial area. Open composting of mixed household waste could be undertaken on existing landfill sites. However, composting does have disadvantages. The composting of all domestic waste is not possible in practice and, in any event, would yield too much for the market to cope with. It may also retain heavy metals and this could result in potential contamination problems.

14.28 Both anaerobic digestion and composting produce odour and there is also a potential for emissions to the air from the gas produced. A large digestion or composting plant would also be a significant traffic generator. The process may be visually intrusive. This can arise from the buildings associated with the process and the storage and treatment of the waste outside.The following Policy will apply: -
