Gregor Ziegler GmbH was founded on 04.12.1990 and manufactures and sells biomass fuels (including wood pellets and wood briquettes), bark mulch and wood fibers as well as potting soils and planting substrates. The company operates a biomass power plant for electricity generation whose exhaust heat is used for drying the biomass fuels; feed-in tariffs are contractually fixed until 2024. In addition, the company runs local and long-distance logistics with its own fleet, trades complementary goods, and sells mainly in Germany and neighbouring countries; raw materials are mainly sourced from Bavaria and Thuringia, while peat is supplied from the Baltic region. Production sites include the main location in Stein/Ploessberg, a wood-fibre plant in Rheinmünster and a soils plant in Wiesmoor; the company has secured long-term supply relationships and fixed off-take agreements to stabilise supplies and sales.
