Toyota's engine plant in Deeside, North Wales, has begun using biomethane and electricity from a neighboring anaerobic digester, replacing natural gas in its production process. The company says this makes it the first Toyota factory outside Japan to move to carbon-neutral manufacturing, with full accreditation under ISO 14068 expected after a year of verified production in 2027. The digester, a 282 million pound privately funded facility, processes around 180,000 tonnes of local waste per year. Toyota estimates the gas switch alone will save nearly 3,000 tonnes of CO2 annually. The site already sources renewable electricity and sends no waste to landfill. Engine blocks now also include recycled aluminum from old alloy wheels supplied by Toyota's circular factory at Burnaston. Toyota Motor Europe plans to reach carbon-neutral production at all its European plants by 2030. The Deeside story is a useful example of industrial fuel switching and circular material use, though the final accreditation date will show whether the claim holds up to independent reporting.
