New Trends in Substrates and Biogas Systems in Poland
The amendment to the Polish Renewable Energy Act creates great opportunities for the development of the biogas
market in Poland. Years of experience in biogas production in Western Europe and the development of biogas
installations in Poland indicate the requirement to look for alternative substrates to those produced from dedicated
crop production (mainly maize silage). Feasible solutions include the use of biodegradable waste from agriculture
or industry as well as municipal landfill sites. The usage of these substrates in the methane fermentation process
offers low cost, high biogas production and the safe management of biowaste. The arguments for using them in
biogas installations are persuasive. This article presents new approaches of biogas plant installation solutions
which allows for the effective fermentation of biowaste from animal and vegetable production, from the agro-food
industry and from municipal wast
The Future Agricultural Biogas Plant in Germany: A Vision
After nearly two decades of subsidized and energy crop-oriented development, agricultural biogas production in Germany is standing at a crossroads. Fundamental challenges need to be met. In this article we sketch a vision of a future agricultural biogas plant that is an integral part of the circular bioeconomy and works mainly on the base of residues. It is flexible with regard to feedstocks, digester operation, microbial communities and biogas output. It is modular in design and its operation is knowledge-based, information-driven and largely automated. It will be competitive with fossil energies and other renewable energies, profitable for farmers and plant operators and favorable for the national economy. In this paper we discuss the required contribution of research to achieve these aims.Peer Reviewe
