Straw becomes suitable for biogas production after a pre-treatment. Especially biogas production out of straw is feasible in countries with the hot climate, where straw is cheap, not used for heating during winters and mainly burned in the fields. Such countries are, for example, Spain, Greece, Egypt, Turkey, Brazil, India.

Straw becomes suitable for biogas production after undergoing a pre-treatment process. Biogas production from straw is particularly viable in countries with hot climates, where straw is abundant, inexpensive, and often not used for heating in winter but instead burned in the fields. Countries such as Spain, Greece, Egypt, Turkey, Brazil, and India are examples where straw can be effectively utilized for biogas generation.

When considering the construction of a biogas plant, agricultural companies typically think about growing maize for silage. With this approach, land is dedicated either to grain or silage production. However, with new technologies for preparing straw, there is now a viable alternative to maize silage. This allows enterprises to maximize the benefits of their land by producing both grain and biogas from straw. Substrates that are suitable for biogas processing include wheat straw, sunflower straw, rice straw, paddy straw, bagasse, and corn stover.
