Calderdale Council is exploring proposals for a new pyrolysisPyrolysis is a thermochemical process that converts waste biomass into bio-char, bio-oil, and pyro-gas. It offers significant advantages in waste valorization, turning low-value materials into economically valuable resources. Its versatility allows for tailored products based on operational conditions, presenting itself as a cost-effective and efficient More plant, a project aimed at managing green waste more efficiently and generating a valuable byproduct. The facility, under consideration for the Atlas Mill waste and recycling site in Brighouse, would process household green waste through a process that uses high temperatures to break down organic materials in the absence of oxygen.

​The primary objective of the proposed plant is to tackle the council’s substantial annual green waste disposal costs, which currently amount to around £240,000. By converting this waste into useful products, the council could potentially transform a financial burden into a revenue stream. The process would produce biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More, a carbon-rich material with applications in agriculture for improving soil health and in water filtration.

​A crucial aspect of the proposal is the need for clear and transparent communication with the public. Councillors have stressed the importance of explaining that the process is not incineration and that the plant would handle only green waste, avoiding potentially harmful materials like plastics or tires. This proactive approach is intended to mitigate public apprehension and ensure community support for the project.

The council is evaluating various operational models, including running the plant independently or forming a partnership with a specialized company. A full business case, detailing the financial and logistical aspects, is anticipated to be presented to senior council members for approval by the end of the year. The council will have to borrow to fund the endeavour with a 75/25 council/private split of ownership thought to be preferred at this point. The initiative reflects a commitment to innovative waste management strategies that align with sustainability goals while offering economic benefits.
