WELTEC BIOPOWER Extends AD Plant in France
Breton Biogas Plant to Be Stepped up to 500 kW

October 17, 2017

Together with its French partner WELTEC Agripower, German biogas plant manufacturer WELTEC BIOPOWER is currently working on an extension AD project in Iffendic, Brittany. The biogas plant in Iffendic had already been built back in 2014, and now its capacity is being doubled. The biogas plant now generates 500 kW a day, enough to supply almost 1,000 households.

Apart from the needs-oriented planning and the high quality of the AD plant, the smooth rollout of the initial construction project was a key reason why the operator Samuel Morand decided to entrust WELTEC with this follow-up project. Again, everything went smoothly: After the quick approval process, the groundworks were finished within a short time, and WELTEC commenced with its work, which also progressed speedily", says the owner of the young bull and pig fattening facilities, commenting on the rapid project rollout. Our great experience and the close coordination of all processes with our project partner WELTEC Agripower played a key role in this achievement", says Alain Priser, who oversees the business in France at WELTEC. Thus, the expanded plant went online after a building time of only a few months.

Samuel Morand already had the idea of extending the plant when the original biogas plant was being built. However, as he only had a limited amount of cattle manure, pig manure, whole crop silage, cereal debris and apple pulp at his disposal, he initially decided to implement just one 2,625-m³ stainless-steel digester and a 250-kW CHP. Nevertheless, WELTEC proactively designed the other plant components, such as the dosing feeder and the pumps, for the double plant size. The robust input system MULTIMix was also implemented in such a way that it can now easily supply a second digester. The MULTIMix ensures efficient shredding of long-fibre and sticky substrates such as cattle manure and whole crop silage, thereby enabling use of the full energy potential.

Over the past years, the operator has successfully enlarged his agricultural business and now has a greater amount of cattle and pig manure at his disposal. Moreover, an apple juice manufacturer is now able to supply Morand with more waste from his production. This increase in the available substrate forms the basis for the plant extension by an additional 2,625-m³ digester and an additional 250-kW CHP.

Another benefit for French farmers: In December 2016, the feed-in tariff for power from agricultural biogas plants was raised, especially for the input of liquid manure. Moreover, the maximum compensation period has been increased five years to a total of 20 years. Both the term and the amount of the tariff ensure more planning and investment security in the industry. Another positive aspect for Samuel Morand s operations is that he can use the exhaust heat from the CHP unit for his pigsties and digestate drying.

In this way, this measure means a win-win situation: France is approaching the goal of stocking up the proportion of renewable energies to 30 percent by 2030. The figure currently amounts to 19 percent, and especially the contribution of biogas to energy production can be further expanded. The new compensation strengthens the role of biogas, allowing this energy source to demonstrate its strength within the scope of the French energy reform: The advantage of biogas over other renewable resources is the ability to control the timing and amount of energy generation and the storability. This makes biogas a valuable component of the energy mix, which not only improves the carbon balance, but can also contribute significantly to grid stability, security of supply and a recycling economy.

Company Portrait
WELTEC BIOPOWER GmbH is one of the world s leading enterprises in the field of stainless-steel biogas plant construction. The company has planned, developed and built anaerobic digestion plants since 2001. Today, the medium-sized company has about 80 employees at the headquarters in Vechta, Germany, and has established more than 300 energy plants in 25 countries worldwide. The global distribution and service network spans six continents. The range of customers includes businesses from the agriculture, food, waste and wastewater industries.

The strength of WELTEC BIOPOWER lies in custom-tailored design and technically mature solutions for projects up to 10 megawatt capacity. In this context, the high proportion of internally developed components is a key success factor. The company also owes its leading edge to the use of stainless steel. This enables the input of a diverse range of feedstocks, a fast and economic assembly and a consistently high quality standard - regardless of the location.

After a biogas plant goes live, WELTEC BIOPOWER offers additional support through its experienced mechanical and biological service team. 24/7 availability and an in-house lab contribute significantly to the efficiency of the plant.

Nordmethan, a subsidiary company of WELTEC BIOPOWER , addresses another business area: The operation of biomethane plants and the provision of heat through energy contracting. In this way, the WELTEC Group covers the entire value chain of energy generation with biogas and biomethane - from the plant construction to the plant operation.
