Organic Waste Treatment


The WELTEC Group from Vechta, Germany, has developed into a globally leading specialist for the construction and operation of biogas and biomethane plants since it was founded back in 2001. The Group designs, plans and sets up energy plants, operates them on a permanent or temporary basis, provides 24/7 service and delivers sustainable usage concepts for output flows, thereby covering the entire biogas value chain. The establishment of individual, technically mature solutions up to a plant size of 10 MW is one of the strengths of WELTEC BIOPOWER. The high proportion of custom-developed components is a key success factor. The company also boasts a wealth of experience in the field of biogas generation and utilisation. The company's nine decentralised plants at the moment generate 96 million standard cubic metres of biogas annually. Most of it is processed to biomethane and made available to energy suppliers and petrol station operators via the public gas network. The modern biogas plants are designed for the efficient use of different raw materials. Customers include companies from the waste and food industries, agriculture and the wastewater sector. In the meantime, the WELTEC Group with its 120 employees has already realised more than 350 energy plants in 25 countries on 5 continents.
