Carbon dioxide removal

Microbes and mineral carbonation bind aggregate into cement at room temperature — replacing the 1,500-degree kiln that makes Portland cement responsible for roughly 8% of global CO2 — turning concrete into a carbon-negative climate asset sold as tiles, self-healing structures and CO2-derived aggregates.

Pyrolysing biomass into stable biochar — or fast-pyrolysis bio-oil injected underground — turns atmospheric carbon into a durable, monetisable climate asset, with soil-amendment value and certified carbon-removal credits as the twin revenue streams.

The reactor and balance-of-plant hardware that carbonises biomass into biochar plus heat and power — modular continuous carbonisers, biomass-cogeneration-coupled pyrolysis, and batch or mobile units — supplied by specialist manufacturers whose equipment is what makes certified biochar carbon removal physically possible.

Turning captured CO2 into fuels, proteins, polymers and methanol via microbial gas fermentation, engineered microbes and algae — a carbon-utilization value chain from industrial emissions to circular carbon products.

Carbon captured by marine ecosystems — mangroves, seagrass, salt marshes and cultivated seaweed/kelp — and the emerging industry of ocean farming, Sargassum valorization and marine carbon-dioxide removal (mCDR) that monetizes it via biomass products and durable carbon-removal credits.

Direct air capture with bio-integration — carbonic-anhydrase-functionalized sorbents and engineered-microalgae photobioreactors that cut DAC regeneration energy and cost via low-temperature desorption.

Crushed silicate rock — usually basalt — spread on farmland to accelerate the natural weathering reaction that draws down atmospheric CO2 into stable dissolved bicarbonate, with the added draw of a real agronomic side-benefit: the same application also raises soil pH and releases nutrients.

Accelerating the ocean's natural carbon sink by adding alkaline minerals to seawater to safely sequester CO2.
