Biochar Carbon Hill

Biochar from tree, hedgerow cuttings, and green waste from parks and gardens

Carbon Hill is a biochar company owned by the Jones family located in Caebardd farm, near Welshpool in mid-Wales, UK. The family, who have been farming for many years, have diversified their operations by leveraging their expertise in biomass and mechanical engineering. Their engineering arm, Woodtek Engineering, designs and manufactures efficient wood chip dryers and feed mechanisms. The company has developed a proprietary pyrolysis thermal combustion system that utilizes new and existing technologies to produce biochar with minimal emissions. The system is operating at Caebardd, but the company has rolled out several pyrolysis units to process waste biomass in the UK and internationally. Carbon Hill sources two types of waste woody biomass for their biochar production: Tree and hedgerow cuttings and Green Waste Over Size (GWOS) from local parks and gardens. These feedstocks are largely underutilized in the UK and are typically either left to biodegrade or burn, leading to carbon loss. The biochar is applied to agricultural land, including Carbon Hill’s own farm and nearby partner sites, improving soil quality and supporting regenerative practices. Biochar is also used in collaboration with academic partners for research trials, contributing to data generation and validating agronomic benefits.
