Smokeless Household Waste Carbonization & Direct NaOH CCU System

Every day, municipalities and industries face the twin challenges of escalating household waste and rising carbon emissions. Conventional disposal methods either leak methane in landfills or release uncontrolled smoke and CO2 through open burning.

Turning household waste into a zero-smoke, closed-loop resource engine is no longer just a concept—it is an engineering reality. 🌱⚙️

At BioCom, we believe environmental performance is an engineering constraint, not a cosmetic layer. Every day, municipalities and industries face the twin challenges of escalating household waste and rising carbon emissions. Conventional disposal methods either leak methane in landfills or release uncontrolled smoke and CO2 through open burning.

Our integrated Smokeless Household Waste Carbonization & CCU System transforms this liability into two high-value industrial commodities: Biochar and Sodium Carbonate / Bicarbonate (NaCO3 / NaHCO3).

How the Closed-Loop Process Works:

1️⃣ Thermal Pre-Drying (Fluidized Bed Dryer): Hot combustion flue gases and pyrolytic vapors are recycled upward through a perforated plate, suspending wet, shredded household waste in a fluid-like state for rapid, energy-efficient moisture removal.

2️⃣ Autothermal Carbonization (Fixed-Bed Reactor): Dried feedstock enters a fixed-bed kiln heated by combusting a controlled fraction of the carbonization product itself—eliminating external fossil fuel dependency while producing stable, carbon-rich biochar.

3️⃣ Zero-Smoke Flue Trap & Direct CCU: Rather than venting exhaust into the atmosphere, flue gases pass through a direct NaOH Carbon Capture and Utilization (CCU) scrubber, locking away CO2 and converting it into valuable Na2CO3 and NaHCO3 slurry.

By coupling waste-to-biochar thermal conversion with direct chemical carbon capture, we can achieve 99.8% mass balance efficiency and 75%+ embodied carbon reduction—proving that circular material loops can be modular, scalable, and economically self-sustaining.

We are actively partnering with municipal leaders, industrial estates, and sustainability pioneers across Indonesia and beyond to deploy field-tested circular infrastructure.
