Humidity, dirt, swarf, heat and cold: these are just some of the many environmental and weathering effects in which composting and waste incineration plants have to function reliably to avoid expensive machine downtime. For composting, fail-safe components are indispensable to ensure that the complicated, self-contained composting process is not disturbed. The aim is to produce high-quality compost from biodegradable waste so that it can be used as a fully effective fertiliser in gardening and farming. In heavy-duty areas, steel systems are increasingly being replaced with igus products due to their exceptional suitability.
