200KT Compost Plant
200KT Compost Plant
The 200,000 tons/year compost plant is designed as a medium-scale, fast-deployable circular-economy asset, converting agricultural biomass residues and livestock manure into certified organic compost.
It provides early revenue generation, strong ESG impact, and feedstock discipline while preparing the ecosystem for downstream biomass power plants.
This asset offers low technical risk, short construction timelines, and stable, utility-like cash flows independent of power-sector licensing.
