Why Southeast Asia’s next climate unicorn might be built from farm waste
Biochar is easy to dismiss as a climate-tech curiosity. It shouldn’t be. Across Indonesia, Vietnam, Thailand, the Philippines and Malaysia, it sits at the intersection of five problems regional governments already spend money on: agricultural waste management, seasonal haze, soil degradation, industrial wastewater, and rural income. Few climate technologies touch all five at once. The […] The…
Southeast Asia's agricultural waste stream holds significant potential to become the foundation for a climate unicorn. The region's abundance of feedstock, including rice straw, palm oil residues, rice husks, coconut husks, sugar cane bagasse, and more, presents an opportunity to address multiple environmental challenges simultaneously.
Biochar, a carbon-rich substance produced through pyrolysis of biomass waste, can simultaneously tackle agricultural waste management, seasonal haze, soil degradation, industrial wastewater, and rural income issues. Southeast Asia's geographical diversity allows for a varied feedstock base, turning waste disposal costs into potential revenue streams through biochar production, heat/energy generation, and carbon removal credits.
Carbon removal, in particular, presents a promising opportunity, with successful proof points in the Philippines and Thailand. Carbon removal certificates have already been generated in the Philippines and Thailand, with further credit opportunities on the horizon from multinational corporations. The agricultural sector is another promising market, as biochar can improve soil health, water retention, and nutrient-use efficiency, addressing the nutrient and water stress faced by paddy soils in the region.
Wastewater treatment is an underexplored area where biochar's porous nature can be utilized to treat polluting byproducts like palm oil mill effluent (POME) and general industrial and municipal wastewater, potentially generating better margins than generic biochar. The key to unlocking this opportunity lies in identifying high-value biomass currently stranded and transforming it into a high-value product.
A platform layer approach, aggregating biomass from smallholders and mills, operating distributed pyrolysis units, tracking feedstock and output, certifying carbon removal, and selling both the physical product and carbon credits, represents a climate-infrastructure business rather than a commodity one. This approach is closer to what regional players like Alcom are assembling and holds significant promise for Southeast Asia's climate future.
