Biochar for Scotland: creating value from waste
Isle Utilities explored the benefits and impacts of biochar made from biosolids and waste streams for our client, Scottish Water.
Biochar produced from waste can help mitigate carbon emissions by sequestering carbon, enhancing soil health and promoting carbon storage. To date, research around biochar production and use has predominantly centered on biochar from plant-based sources. Exploring water utility
feedstocks, like sewage sludge, could yield significant value, yet research is still in the early stages. Isle undertook research to determine the current state of biochar knowledge and identify the value it could provide for Scotland. The team critically reviewed evidence and facilitated a
panel of globally recognised experts to address the topic. Experts assessed and prioritized nine possible uses, including four that could have a benefit within Scottish Water operations. They also identified 16 research needs to advance Scotland’s valorization of biochar.
