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 utilisation. The company’s nine decentralised plants generate 96 million standard m³ of biogas a year. Most of it 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– e.g. 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.
The biogas specialist is 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 80 employees of the WELTEC Group have implemented more than 300 energy plants in 25 countries on five continents. These plants save about 485.000 tons of CO2eq a year.
The fermentation of organic waste is a special focus of WELTEC – this also includes the use of potato leftovers to generate energy. WELTEC has already successfully implemented such systems for customers in several countries. A plant in France was built in 2018 and annually uses around 22,000 tons of residues from potato chips production. Approx. 1.75 million Nm³ of green gas with an energy value of 17,440 MWh are extracted from this annually. The return on investment is significantly less than five years for this sustainable and climate-friendly project.
