Biofertilisers Service
Agrivert locates its facilities close to product markets. All our compost and digestate products are recycled to land locally to maximise environmental sustainability.
Digestate
Agrivert’s anaerobic digestion facilities are designed to produce a liquid digestate fertiliser to BSI PAS110 and Quality Protocol standards.
See our latest official PAS110 sample results. Our sample has zero plastics and was well within the limits for all other constiuents including heavy metals!
Agrivert’s long AD retention times produce a stable and low odour product that is ideal for complete chemical fertiliser replacement.
Compost
Agrivert produces compost to BSI PAS100 and Quality Protocol standards (for more information on BSI PAS100 please visit the AfOR website). The product has to meet strict feedstock and end product specifications and is suitable for use on organic farms. Our compost products are currently sold in bulk from sites in Oxfordshire and Hertfordshire.
Biosolids
Agrivert offers robust, cost-effective sewage sludge treatment processes. By use of a variety of treatment methods to suit individual circumstances, Agrivert produces compliant dewatered ‘sewage cake.’ The cake is spread to land as an agricultural fertiliser, complying with all regulatory and statutory requirements. The application to land is carried out in line with the Safe Sludge Matrix.
Agrivert also offers an anaerobic digestion solution that can treat sewage sludge. This removes energy from the sludge, reduces its quantity and removes much of the odour. The process produces a biofertiliser product (digestate) that can be dewatered and used as an agricultural fertiliser.
Biofestiliser benefits
Our biofertiliser products:
- Provide an excellent source of NPK and S to replace chemical fertilisers
- Improve soil structure, drainage, water retention and aeration, providing a better rooting environment for plants
- Possess slow nutrient release qualities. The material continues to breakdown within the soil, reducing nitrogen and phosphate leaching, which can occur with chemical fertilisers
- Improve the workability of soils, especially heavy clay
- Improve water retention in light soils
- Enhance resistance to soil compaction and erosion.
- Reduce the need for artificial fertilisers
