Innovation with Tradition. As a pioneer in composting, we have prioritized the closed-loop material cycle from the very beginning. The result: the production of sustainable, environmentally friendly, and market-oriented products through successful recycling. Respect for nature and the responsible use of raw materials are our guiding principles now more than ever. Resource conservation also extends to energy consumption: Since November 2024, we have operated a photovoltaic system in Remseck. RETERRA Soils was one of the first manufacturers to produce a bio-substrate that meets the strict guidelines of the EU Organic Regulation. With approximately 50 employees, we produce quality-controlled substrates at our plants in Remseck and Aichach: soil improvers, mulch products, ready-to-use potting soils, tree planting and green roof substrates, and organic products for all areas of horticulture, trade, landscaping, and parks departments. At our plant in Öhringen, we operate a modern composting facility with a throughput of 51,500 tons per year as part of our overall concept. As a certified waste management company, we thus ensure access to high-quality and environmentally friendly additives for the production of our soils and substrates.
