Waste to Compost Process

1. Organic waste delivered to Envar is weighed and visual check undertaken.
4. Over a period of 7 to 10 days, temperatures of 60°C are achieved & sustained for at least twenty four hours. Procedure is managed at all times to comply with ABPR and ensures the destruction of any weed seeds & pathogens in the material.
2. Incoming material streams are then shredded and blended to produce a homogenous mix for composting.
5. Product is moved from the IVC bunkers to nearby maturation windrows where the material is left to mature further. During this phase, (8 & 12 weeks), the product remains carefully monitored to ensure optimum temperature & moisture content.
3. Blended material is loaded into one of the enclosed in-vessel bunker systems complete with aeration system, temperature control & wireless data logging probes. Decomposition is carefully controlled to ensure EU composting standards are met.
6. After screening and grading the result is a range of stablised, nutrient-rich, peat-free products suitable for use as soil improver, mulch, compost or soil replacement material.
