How do we solve two of the biggest environmental challenges at once—diverting organic waste from landfills and decarbonizing global chemical manufacturing?

At BioCom, our vision bridges the gap between circular waste management and advanced chemical engineering. We are rethinking green ammonia (NH3) production by ditching fossil fuels and heavy grid-tied water electrolysis entirely.

Instead, we use an integrated, low-emission, four-step thermochemical looping system:

1️⃣ Waste Valorization: Organic waste is carbonized into stable biochar, followed by targeted gasification to produce a high-quality, carbon monoxide (CO)-rich syngas.

2️⃣ Steam-Iron Redox Looping: Instead of expensive precious-metal electrolyzers, the syngas (CO) reduces magnetite (Fe3O4) to elemental iron (Fe). Introducing superheated steam to the reduced iron then yields ultra-high purity hydrogen (H2), cycling the iron carrier indefinitely.

3️⃣ PSA Air Separation: Low-energy Pressure Swing Adsorption (PSA) isolates nitrogen (N2) straight from the atmosphere on-site.

4️⃣ Green Haber-Bosch Synthesis: Pure N2 and H2 streams are combined to synthesize green ammonia—delivering zero-carbon fertilizer and zero-emission maritime fuel.

Why this shifts the paradigm:

Grid Independence: The chemical looping loop acts as a thermal buffer, smoothing out the intermittent nature of renewable wind and solar power.

Cost Efficiency: Abundant, non-toxic iron oxides replace expensive iridium/platinum catalysts found in standard PEM water electrolysis.

Zero Logistics Overhead: Modular, decentralized deployment brings production directly to municipal hubs and agricultural centers.

Real sustainability is an engineering constraint, not a cosmetic layer. Let's build infrastructure that lasts.
