Central Asia steps in biogas production
Last week the first biogas plant in Central Asian region with a capacity of 500 kilowatts was launched in Shymkent, Kazakhstan.
The project was announced for during the International Specialized Exhibition EXPO-2017 and was realized jointly with the Czech company HEDVIGA GROUP, provider of technical solutions in the field of fuel and energy production from waste.
The technology is based on the process of methane decomposition of biomass, namely sewage water and municipal treatment facilities wastes. As a result, the unit produces 300 cubic meters per day of biogas or methane-containing gas, electricity and thermal energy.
The cost of the project amounts near US $ 6.6 million.
The biogas is composed of methane (50-87%), CO2 (25-50%) and small quantities of hydrogen, nitrogen, oxygen. The biogas treated from carbon dioxide is called biomethane, which is full analogue to natural gas.
The production of biogas reduces global climate emissions by 20%.
According to the market research company ReportBuyer, there are currently over 12,000 biogas plants in the world with a total capacity of about 7,000 MW. More than 90% of these facilities are located in Europe and Germany is home for about two-thirds of all biogas plants, existing on the planet. However, the number of biogas plants will increase to 15,000 all over the world and their capacity will raise to 9600 MW by 2025.
London-based World Biogas Association says that dung, received from two cows is enough for biogas plant, while major biogas parks processing up to 500,000 tons of food waste and sewage can support industries of any scale.
