Southeast Asia produces some of the world’s most abundant agricultural residue streams, rice straw from the Mekong Delta to Luzon, sugarcane bagasse from Thailand to the Philippines, coconut byproducts across the archipelagic economies of Indonesia and the Pacific rim. Collectively, these represent billions of dollars in untapped feedstock value.
And most of it gets burned.🔥
The open-field burning of crop residues is one of Southeast Asia’s most persistent and underreported environmental problems. It contributes significantly to the seasonal haze events that blanket the region, degrades soil quality over successive cropping cycles, and represents an enormous opportunity cost, carbon that could be sequestered, nutrients that could be returned to the soil, and materials that could enter productive value chains are instead released as pollution.
What’s striking is how well-understood the alternatives are. Biochar, biomass energy, composting, animal feed supplementation, and bio-based material production are all proven pathways.
What’s missing is the regional coordination, shared standards, cross-border market linkages, and investment in the aggregation infrastructure that makes circularity economically rational for smallholder farmers who generate the bulk of these residues.
Southeast Asia doesn’t lack circular economy potential. It lacks the systems to capture it.
Which country in the region do you think is closest to getting this right, and what are they doing differently?
