About Bioenergie Markmüller

Bioenergie Markmüller is a sole proprietorship based in Hofkirchen in the district of Passau (Lower Bavaria). Owner Florian Markmüller offers services along the biomass value chain: wholesale and retail trade in wood chips, transport, drying and power generation. Among other things, the company supplies the local district heating network and provides heat from biomass to connected customers in Hofkirchen. In February 2022, the company was supported by the partner Hackschnitzel Wenninger in the transport and drying of wood chips for the citizens of Hofkirchen. In August 2025, provisional insolvency was filed for the company; the heat supply of the approximately 110 connected customers was initially secured by mobile heating plants. The information is based on public sources such as the company website, Creditreform and local press reports.
