Yorwaste & its subsidiary company, SJB Recycling has provided green waste composting services for various local authorities and business for well over ten years and with over 200,000 tonnes a year, we are now one of the largest composters in the UK.
The companies operate a large number of composting facilities across the UK that meet appropriate regulations for undertaking open-windrow composting, including grass cuttings, leaves, weeds and hedge trimmings collected from household waste recycling centres, kerbside collections and commercial collections.
Open windrow composting is a managed process in which biodegradable green waste is broken down by naturally occurring micro-organisms to produce a stable residue. Waste is collected and brought to the site where it is checked to ensure it is of sufficient quality. It is then shredded and arranged into windrows, which are elongated piles shaped for composting. Aeration is encouraged by mixing of the material and regular mechanical turning.
Bacteria break down the material to produce heat which transforms and sanitises the product, turning it into rich, dark compost. At the end of the process we produce a high quality soil conditioner that is accredited, at some sites, to the national BSI PAS 100 composing quality assurance standard, certified by the Association for Organics Recycling.
