Biokolprodukter - Cortus Energy

Cortus operates a renewable gas and biochar facility in Sweden, using advanced pyrolysis and gasification technology. The system converts locally sourced forest residues into renewable energy gases and stable biochar. The renewable gas replaces fossil fuels in industrial processes, such as the steel industy, while the biochar provides long-term carbon storage and is used as a soil amendment.

By combining clean energy production with carbon sequestration, the project demonstrates how circular bio-economy solutions can decarbonize heavy industry while creating verifiable carbon sinks.

Cortus began with a vision to produce renewable energy and industrial gas from biomass. Through advanced pyrolysis and gasification, they turn forest residues into synthesis gas and biochar. The gas replaces fossil fuels in industrial processes, while the biochar provides a stable carbon sink as soil amendment. This approach merges energy innovation with climate action, showing how circular technology can transform industrial energy systems and strengthen Sweden’s transition toward a fossil-free economy.

"With an EBC-certified biochar, the value of the biochar increases and gives us the foundation for new business opportunities,”

Rolf Ljunggren, Founder

• The project integrates gasification and biochar production in a circular process. It replaces fossil fuels, supports a greener steel industry, and stores carbon in soil, providing both clean energy and long-term carbon sequestration.
• The project converts local biomass residues into renewable gas and stable biochar, preventing CO₂ emissions and reducing reliance on fossil fuels. By replacing fossil energy in industry and transportation, it supports large-scale decarbonization while enhancing urban green spaces and improving stormwater management practices.
• The project has been contributing to innovative solutions and job creation by processing local biomass residues. It's been supporting local industries with renewable energy and strengthened Sweden’s transition toward self-sufficiency in clean fuels. The biochar, applied in urban soils, improves soil health, ecosystem services and promotes circular resource use. The project aims to inspire similar industrial biochar-energy initiatives across the Nordics.

• European Biochar Certificate (EBC) and EBC C-sink – certifies sustainable biochar production, analytical thresholds, and environmental compliance.

Biokolprodukter Global, established in 2019, is a Swedish company that partners with projects to help them improve their existing bioenergy facilities to simultaneously produce biochar. They specialise in the development and sale of biochar products aimed at enhancing soil quality and combating climate change. Their offerings include pure biochar, nutrient-enriched biochar blends, and machinery for biochar production.

At Biokolprodukter, they believe biochar can drive both climate action and sustainable local growth. Their mission is to make certified Swedish carbon credits a tool that strengthens biochar production and use—turning climate goals into real carbon removal and soil improvement. By linking local producers with climate-conscious buyers, they create a self-reinforcing cycle of climate and environmental benefits.
