WELTEC BIOPOWER – Anaerobic Digestion
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. Moreover, the use of stainless-steel technologies ensures flexible substrate input, quick and inexpensive assembly and a consistently high quality standard, regardless of the location. Following the commissioning, WELTEC‘s mechanical and biological service plays a significant role in ensuring the plant efficiency.
The company also boasts a wealth of experience in the field of biogas generation and utilization. At ten of its own locations and five locations that are operated for a fund, the plants there produce around 155 million standard cubic meters of biogas annually. A portion is processed to biomethane and made available to energy suppliers and petrol station operators via the public gas network. Additionally, at 16 locations in Germany in the field of horticulture, housing construction and healthcare as well as communities – the biomethane is used for generating heat within the framework of WELTEC energy contracting.
As biogas specialists they are well aware of the importance of customer and investor proximity. Accordingly, the Group's sales and service network spans the entire globe. The range of customers includes businesses from industries such as agriculture, food, waste and wastewater. So far, the 120 employees of the WELTEC Group have implemented more than 350 energy plants in 25 countries on five continents. All in all, the biogas specialists responsible for annual savings of around 530,000 tons of CO2eq.
