Biogas is a mixture of about 60% methane, 40% carbon dioxide and traces of other contaminant gases. The exact composition of biogas depends on the type of feedstock being digested. Biogas can be combusted to provide heat, electricity or both. Alternatively, the biogas can be 'upgraded' to pure methane, often called biomethane, by removing other gases. This pure stream of biomethane can then be injected into the mains gas grid. One cubic metre of biogas at 60% methane content converts to 6.7 kWh energy.
Biogas can be combusted to produce heat alone. Some of this energy can be used on site to maintain the temperature of the digester and to heat nearby buildings. However, even small plants will have an excess of heat. The heat can be transferred via hot water to remote users by a district heating system, a concept widely used in some European countries like Denmark, or more likely in the UK used by horticultural and industrial businesses in the vicinity. Using biogas for heating requires investment in new infrastructure, and installations can benefit from the Renewable Heat Incentive (RHI) support. The RHI includes support for biogas combustion and for biomethane injection into the national grid at all scales.
Electricity generation is a relatively straightforward use for biogas and it can be the most profitable. Biogas requires minimal investment in cleaning and upgrading and electricity is supported under the ROCs and FiT Schemes. Electricity is easier to transport than heat and supply is easily measured. Electricity storage, however, is not simple and connecting to the electricity network is costly.
These days, business and community leaders alike are having the same discussion about how to balance their environmental goals with their budgetary ones. Mixed recycling from Waste Management provides an efficient, sustainable solution to help achieve both. Waste management is all the activities and actions required to manage waste from its inception to its final disposal. This includes amongst other things, collection, transport, treatment and disposal of waste together with monitoring and regulation. It also encompasses the legal and regulatory framework that relates to waste management encompassing guidance on recycling etc. The term usually relates to all kinds of waste, whether generated during the extraction of raw materials, the processing of raw materials into intermediate and final products, the consumption of final products, or other human activities, including municipal (residential, institutional, commercial), agricultural, and special waste (health care, hazardous household waste, sewage sludge). Waste management is intended to reduce adverse effects of waste on health, the environment or aesthetics.
