Our focus is customer satisfaction. We strive to maintain long-term relationships by offering high-quality products and services along with constant customer support. As a result of ongoing research and development, we are constantly improving our portfolio of products and services, enabling us to provide our clients with updated solutions in an industry that changes rapidly.
The majority of our plants are located within Europe, Asia and North America, with the global market being served by licensed partners. Our biogas engineering operations unfold along the entire biogas value chain including project development and planning, co-investment, turnkey construction, and operation of biomethane and biogas plants of various capacities. In addition to engineering, we also own and operate biogas and biomethane plants ourselves (OPO- Own Plant Operations).
BIOGEST recognizes the need to convert organic waste into clean and renewable energy because of rising worldwide waste production and demand for energy. With our products, we can offer an important contribution through the use of renewable, raw materials to achieve climate goals. In contrast to fossil resources, biogas production releases only as much CO2 as the renewable resources drew from the atmosphere during their growth.
Our work is designed to be a valuable contribution to society, and we take pride in our social and societal responsibilities. By partnering with us, you can experience this same gratification. We treat our customers and employees equally, irrespective of ethnic background and gender. BIOGEST is proud to provide charitable organizations with above average levels of support.
