Mexican cleantech firm G2E showcased its hydrochar technology at COP31. Instead of drying organic waste for pyrolysis, G2E submerges wet municipal waste in water and heats it to 200 degrees Celsius. The process converts organic material into a nutrient-rich fertilizer in 6 to 8 hours, avoiding the energy-intensive drying step used in conventional biochar production. G2E already operates a pilot plant in Mexico City and is expanding to an 800-ton-per-day facility with backing from government and banking partners. The company currently generates emissions avoidance credits by keeping methane-producing waste out of landfills. It is also working with universities to develop methodologies for certifying permanent carbon removal credits from hydrochar, while using low-cost VR tools to teach waste separation in schools.
