Biogas and biogas plant projects

Biogas technology is a multidimensional and progressive field that is constantly being renewed.

It can be utilized to handle waste streams safely, promote nutrient recycling, and produce renewable energy and transport fuels. The technology enables the processing of a wide range of materials, such as sludge, biowaste, industrial by-products, manure and agrobiomass.

The development of biogas plant process technologies and material flows opens up new opportunities for creating value chains. This includes, for example, the productisation of methane refined from biogas and the multiple uses of biogenic carbon dioxide. It is also interesting that hydrogen technology can be utilised in plant operations to increase methane yield. More efficient use of nutrients, trace elements and humus compounds contained in digestate is key to promoting green and sustainable development.

Now and in the future, biogas technology offers the keys to the wider adoption of sustainable, green and fossil-free circular economy solutions.
