We produced a biomass selection report evaluating feedstock suitability, contamination levels, energy characteristics, pretreatment requirements, and biochar application pathways. Each biomass had to support stable pyrolysis operation, deliver commercially relevant biochar, and meet regulatory standards.
We identified four new biomass options that met these criteria. Pyrocore tested them at their Bristol facility to validate conversion efficiency, biochar yield, carbon content, operational stability, and emissions compliance. All four feedstocks were confirmed as technically compatible. This gave Pyrocore an improved understanding of throughput and char quality that they could use in future customer proposals.
The feedstock identification work provided Pyrocore with validated biomass options and pilot trial evidence that they could present to clients across food and beverage residues, agricultural by-products, light industrial organic wastes, and forestry residues. Pyrocore integrated these findings into their commercial pipeline, using the trial data to respond to customer tenders requiring feedstock validation, expand their allowable feedstock list for new markets, and support early sales discussions for diversified waste-to-biochar applications. The company sold a machine for agricultural by-product processing based on this work.
We analysed laboratory results for the produced biochar and reviewed soil application pathways, assessing soil pH interactions, cation exchange capacity improvements, nutrient retention behaviour based on feedstock type, and regulatory constraints for land application. This gave Pyrocore application guidelines showing that high-ash biochars perform well on acidic soils by improving pH and buffering capacity, nutrient-rich chars work well in compost blends, and lower-ash, high-carbon chars suit soil carbon applications and horticultural substrates. Pyrocore can now discuss biochar performance credibly across different agricultural contexts.
