Compost Site

The open windrow compost site is permitted to receive 75,000 tonnes per annum of biodegradable household, commercial and industrial waste and processes 25,000 tonnes of green and clean wood waste per annum.

Incoming green waste is shredded and windrowed prior to screening at 25mm. All oversize is re-processed. A total period of not less than 8 weeks’ elapses before material can be exported to allow sanitisation and stabilisation of the compost.

The site operates to PAS:100 & Compost Quality Protocol standards and all material produced is classed as product.

In addition to the composting operation, a large shed operates as a waste transfer operation bulking black bag waste for onwards transfer to an energy from waste processing facility for waste collected by South Northamptonshire Council.

AD Facility

Material Change operates the Gas to Grid anaerobic digestion facility at the site (owned by Helmdon Blackpits Power Limited) which injects over 300m3 gas per hour into the National Grid near Brackley, Northamptonshire. The site uses Maize, Rye and Grass supplied by local farmers to produce the gas which uses a membrane technology to separate the methane from other gases produced during the digestion processes. The methane is purified further before being mixed with a small percentage of propane so that it can be used in the exactly the same way as the gas in the grid. Although there is no direct control, the majority of the time residents of Brackley and beyond are supplied from the site and are using renewable gas in their homes.

The site produces 20,000 tonnes a year of digestate which is used by the farms that grew the crops to add organic matter and nutrients back to the land. We are always keen to talk to farmers who want to grow crops for the site and enjoy the agricultural benefits of a good break crop, helping them control black grass and other weeds.

Material Change has supplied digestate to various agricultural and horticultural trails helping strawberry growers improve yields.
