Dark Earth

Dark Earth creates durable carbon removal inside one of the world's most land-constrained cities. At the Asia Renew Science facility in Lim Chu Kang, chicken manure from the host farm, recycled wood chips and garden waste from across Singapore are converted into stable biochar through controlled pyrolysis.

The project is designed as a closed urban carbon loop. Local organic residues become a durable carbon store, then return to the city's soils through horticulture, rooftop greenery, vertical landscaping and other approved applications. At full capacity, the facility is expected to process about 39,600 tonnes of organic material and remove about 9,400 tCO2e each year.

This is carbon removal rather than emissions avoidance. Carbon contained in the biomass is transformed into a stable material that can remain stored for centuries. Production data, feedstock origin, process conditions, batch identity and carbon content are tracked through Cula's digital MRV system and independently assessed before certificates are issued.
