Kompost | So stellen wir Kompost bei Sonnenerde her 😍🌱

Making compost isn't rocket science if you know how! In this video, we show you how we professionally produce our high-quality compost at Sonnenerde. After shredding, the tree, shrub, and green waste mixture is temporarily stored in a large pile – for up to several months, depending on the season. This causes the green waste to become very hot and dry completely – making it storable indefinitely, allowing us to create a correspondingly large interim storage facility. This dried shredded material, together with various nutrient-rich sludges and rock flour, is pre-mixed and stacked in a large pile using only a wheel loader, depending on the recipe. The material remains there for a maximum of two weeks, heating up to 60°C. The moisture from the sewage sludge combines perfectly with the dry green waste, resulting in perfectly homogenized and pre-heated material that can then be composted. The intensive rotting process then takes place in very small windrows with a maximum width of 2.5 m and a height of 1.2 m. During the first week, the material is turned daily to ensure that it quickly becomes 100% aerobic. This intensive rotting process is monitored by temperature and gas sensors, and we ensure that oxygen is always present in the windrow core and that the temperature does not exceed 65°C. After two weeks of intensive rotting, this material is moved to the side and placed in the post-rotting stage. Here, it is "only" turned twice a week, and the temperature continuously drops to 40°C. After another two weeks, this compost is returned to larger windrows (up to 6 m wide) for the so-called soiling process – here, it is only turned with a wheel loader every 1-2 weeks (depending on the season). The finished compost matures for 4-8 months at our facility. Before screening, it is placed on small piles and turned daily to ensure that all the tubers are broken up by the wheel loader's movement, allowing the heat from the heat buildup in the large piles to escape, and maximizing the screening yield. This compost then goes to screening – depending on the product line, with a grain size of between 8 and 25 mm.
