BDI to build multimillion biogas plant

Bioenergy firm will build plant with waste separation technology in France

The biogas plant will process waste to generate 2.1 MW of electricity

Firm BDI (BioEnergy International) has obtained a commission to build a biogas plant in France. Following the construction of a plant in Marl, Germany, the company is to build another multi-feedstock biogas plant to process industrial waste. The plant will be located in northern France with an order volume amounting to EUR 4.45m.

The plant will produce almost 4.2 millionnm³ of biogas to create 2.1 MW of electricity per year. This is enough to supply about 4,000 European households. The plant has also been designed in such a way that the capacity can be doubled easily in future.

Edgar Ahn, CSO of BDI, said: "The high flexibility, functional reliability and economic viability of our multi-feedstock technology have already been proved impressively in our biodiesel plants. We are benefitting from our many years of experience in the generation of energy from residual and waste materials in the introduction of our biogas technology.

“This commission is further evidence that we have chosen the right technologies and that the market for biogas plants has tremendous global growth potential," he said.

The plant will contain separation technology to process raw materials and remove contaminants, such as packaging materials, metals or glass from the waste flow.

The unique process is specially designed for the separation of different waste flows into their organic content and packaging materials and for optimum co-ordination. It enables an extremely high purity level to be achieved with the biogas substrate, combined with a clean and dry inorganic material flow.

Edgar said: “This technique makes it possible to feed the biogas substrate directly into our fermentation system, without formation of the floating sludge layer that is frequently encountered in conventional processes, which may lead to operational disturbances. The separation concept is an optimum addition to BDI’s product range."

Work to build the plant is set to start before the end of the year, which will involve installing a system for the handling of leftover food.
A plant to process biological organic residual materials will then be installed, followed by a combustion engine system for the generation of electrical and thermal energy from biogas.
