WELTEC BIOPOWER GmbH, from Vechta, Germany, has received the ”DLG FokusTest” certification from the German Agricultural Association (DLG). A key objective of the test was to check how effectively the biogas plant degrades organic dry substances and thus total carbon for producing biogas. The calculated biogas yield was compared with the maximum possible biogas yield.
The organic dry substance degradation rate amounted to 83.9 percent, and the specific gas yield to 81.5 percent. All values remained constant over the entire test period of almost 147 days. Following the optimisation of the stirring unit settings, a decline was observed in the energy consumption. The electricity needs of the biogas production itself consumed 2.6 percent; the energy consumption for the introduction of solid substances amounted to 3.77 kWh per ton of solid substance.
The degradation rate and the biogas yield were checked over a period from May to October 2010 in a 500 kW biogas plant in Wiefelstede near Oldenburg, Germany, which mainly uses liquid manure and maize silage for the fermentation process. During the check, the percentages of these two substrates increased from 65 to 90 percent. Duck manure, corn-cob mix (CCM), and grass silage were also used, though to a smaller extent. The amount of biogas produced during the entire test period amounted to 736,773 standard cubic meter.
The DLG test engineers regularly test product developments and innovations with the help of modern measurement technology and application-oriented test methods. The ”DLG FokusTest” serves the product differentiation and the highlighting of interesting innovations. According to the German Agricultural Association, the ”DLG FokusTest” mainly concentrates on testing individual quality criteria of a product. The test concludes with the publication of a report and the award of the test mark.

Company Portrait
Established in 2001, WELTEC BIOPOWER GmbH is a leading provider of biogas plants. Based on the modern approach of experienced engineers, the company from Vechta, Lower Saxony, with its staff of close to 70, offers complete biogas plants from one source.
One of the main strengths of the medium-sized enterprise is the ability to deliver individual and flexible solutions – from compact plants to large computer-controlled plants in the megawatt range, waste recycling plants, and biogas parks with gas processing technology.
The Könnern industrial zone between Magdeburg and Halle, Germany, is home to one of the world‘s largest biogas parks, built by WELTEC BIOPOWER. In its capacity as general contractor, WELTEC was responsible for the overall project planning, turnkey setup including the infra- structure, approval planning, production, and installation, as well as the operational launch and comprehensive biological supervision of the park. The concept comprises the processing (amine treatment) and feed-in of biomethane into the natural gas grid. Another WELTEC biogas park in Barsikow, Brandenburg, has been generating up to 4.3 million standard cubic meter a year since the beginning of 2010, and in Arneburg, Saxony-Anhalt, one of Europe‘s largest biogas parks will supply the equivalent of 7,000 homes with power and heat.
The plants have a modular structure. WELTEC BIOPOWER uses only proven system components and develops most of the technologies along the entire value chain internally: fermenter technology, mixing technology, control technology, hygienisation systems, and digestate processing solutions originate from the company.
As the hydrogen sulphide and ammonia compounds contained in biogas corrode unprotected parts, WELTEC builds the fermenters from stainless steel. This ensures a long useful life of the plant. The great manufacturing depth also guarantees a consistently high standard regardless of the location and ensures an export rate that is far above the industry average.
Meanwhile, the company‘s quality is renowned worldwide. In 2009, a Chinese investor engaged WELTEC BIOPOWER GmbH for the setup of a biogas plant. The plant with an output of 370 kWel is China‘s first biogas plant that meets German quality standards.
In 2008, WELTEC BIOPOWER GmbH became one of the first providers of complete biogas plants to be certified by TÜV Rheinland according to DIN EN ISO 14001:2004 and the quality management standard DIN EN ISO 9001:2001.
