Combining solar generation with agricultural activity on the same land — a stack from site assessment to dual-value harvest.

Bioenergy with carbon capture and storage — burning biomass for power or heat and permanently storing the resulting biogenic CO2 — is moving from single flagship pilots to a small cluster of near-term commercial projects in Northern Europe, while a marquee US project shows how permitting risk, not the underlying chemistry, is what actually delays BECCS at scale.

Printing inks whose binders, solvents and additives come from vegetable oils, rosin, lignin and other renewable feedstocks rather than mineral oil — sold as certified renewable-content ranges by Siegwerk, Sun Chemical, Flint Group (TerraCode Bio, BioCure F) and Sakata INX (BOTANICAL INK), where deinkability and food-contact compliance decide adoption as much as bio-content.

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.

Microalgae photobioreactor panels and units built into a building's facade or air-handling system — living CO2/VOC scrubbers that also shade and pre-cool glazing — sold by architecture-biotech studios and consumer-hardware startups as a distinct, algae-based layer from the rooted-plant living-wall biofiltration hardware already covered on this site.

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.

Rewiring natural photosynthesis — enhanced-photosynthesis trees, C4 rice, and new-to-nature CO2-fixation cycles — alongside artificial chloroplasts and bionic leaves that turn sunlight and CO2 into biomass, fuels and biofertilizer.

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.

Acetogenic bacteria fix steel-mill and refinery off-gas (CO, CO2, H2) into recycled-carbon ethanol, acetone and sustainable aviation fuel through the Wood–Ljungdahl pathway — operated at commercial scale by LanzaTech licensees (the 210,000 t/yr Shougang plant, the €200M Steelanol plant at Ghent, and LanzaJet's Freedom Pines alcohol-to-jet facility) and extended to non-steel CO2 feedstocks by Cemvita's engineered-microbe platform.

Thermochemical and biological routes that convert biomass and biomethane into hydrogen — gasification followed by water-gas shift and PSA, bio-SMR of biomethane, and dark-fermentation R&D — anchored by gasification licensors, solid-oxide reformers and energy majors.

Microbial electrosynthesis and power-to-methane: renewable electricity and CO2 fed to electroactive microbes at a cathode that fix CO2 via the Wood-Ljungdahl pathway into acetate, alcohols, biomethane and single-cell protein.
