Food Waste Conversion To Biochar / Activated Carbon

FoodCycle+ leads a pioneering initiative to convert yard and food waste into biochar in Hong Kong and ASEAN. By deploying local pilot plants and advanced pyrolysis technology, the project supports sustainable waste management, soil enhancement, and carbon sequestration, collaborating with CUHK experts and promoting eco-friendly agricultural practices.

Innovative Biochar Production and Team Expertise

The project utilizes a pilot biochar production plant at EcoPark, transforming woody biomass into highly porous biochar through pyrolysis. Supported by a multidisciplinary team—including environmental scientists, engineers, and agricultural experts—the initiative collaborates with CUHK professors to advance biochar research. Team members bring extensive experience in recycling, organic farming, landscape management, and water treatment, ensuring robust technical and operational capabilities. This collaborative approach accelerates the adoption of biochar for soil improvement, environmental remediation, and ecosystem restoration across Hong Kong and ASEAN regions.

Wider Application and Ecosystem Benefits

FoodCycle+ promotes the immediate and extensive use of biochar in landscaping, agriculture, and environmental recovery projects. Applications include soil amendment, landslide vegetation recovery, advanced farming in newly developed agricultural parks, and co-composting with food waste. Biochar enhances soil structure, stability, and biodiversity, aids in slope restoration, and supports carbon sequestration. Field trials and demonstrations involve partnerships with government, private developers, and NGOs, aiming to meet rigorous quality standards and fulfill specifications for soil conditioners and mixes, thereby driving sustainable land management practices.

Advanced Research and Future Directions

The project explores innovative methods for activating biochar and converting it into high-performance activated carbon. Techniques such as microwave-assisted and ozone activation offer energy-efficient, chemical-free alternatives to conventional processes. Activated biochar shows promise in water filtration, pollutant removal, and enhancing soil biodiversity. Ongoing studies evaluate biochar’s effectiveness in decolourization and contaminant adsorption, with preliminary results indicating significant potential. These advancements position FoodCycle+ as a leader in regenerative material development, supporting circular economy principles and environmental health in Hong Kong and beyond.
