As a replacement for natural gas – if biogas is cleaned up and upgraded to natural gas standards, it’s then known as biomethane and can be used in a similar way to methane; this can include for cooking and heating. During anaerobic digestion, organic material is broken down in several steps by different types of micro-organisms. Depending on the feedstocks used, the methane content in biogas varies between 50 and 65%. It’s produced when organic matter, such as food or animal waste, is broken down by microorganisms in the absence of oxygen, in a process called anaerobic digestion. To increase the quality of the raw biogas, the gas is usually purified of unwanted substances such as hydrogen sulphide, oxygen, nitrogen, water and particulates. It can occur naturally or as part of an industrial process to intentionally create biogas as a fuel. Biogas is produced by anaerobic digestion (AD) or fermentation of organic matter, including organic fractions of household and industry waste, manure, sewage sludge, energy crops, biodegradable waste in landfills or any other biodegradable feedstock, under anaerobic conditions. Biogas is a high-energy gaseous mixture, product of the natural decomposition process of organic material in the absence of oxygen, also known as anaerobic digestion. If purified (upgraded) it can be compressed to replace compressed natural gas for use in vehicles, where it can fuel an internal combustion engine. It can be used in a variety of ways including as vehicle … A small amount of biogas is used in transport. What sort of waste can be used to produce biogas? This biological process is referred to as Anaerobic Digestion (AD). The relative quantities of these vary depending on the type of waste involved in the production of the resulting biogas. The biogas composition and the yield of biogas will depend on the substrate composition used during the anaerobic digestion. A typical power capacity would be 1MW / 500 Nm³/h biogas.

Most biogas in New Zealand is produced from landfill sites and wastewater treatment plants and is mainly used for electricity generation. https://www.linkedin.com/company/desotec-activated-carbon. ).
