How we utilize CO₂ efficiently

Patented technology

Reduciner's innovation transforms what has long been seen as a problem into a valuable solution.

Reduciner’s technology is based on a thermally driven carbon conversion process where carbon dioxide reacts with biochar to produce carbon monoxide and activated carbon. CO₂ is used as a feedstock rather than treated as waste, enabling its conversion into valuable industrial products, e.g. carbon monoxide and activated carbon, through thermal energy.

CO₂ + Biochar + Electricity → CO + Activated Carbon

Benefits

Efficient CO₂ Utilization

Industrial CO₂ emissions are captured and utilized from hard-to-abate industries like lime, cement, steel before entering the atmosphere. No major infrastructure replacement required.

Electrical Conversion

Our patented electrically heated process converts CO₂ into a clean carbon monoxide stream and high-value activated carbon. No combustion, no hydrogen losses. Pure electrical energy powers the conversion process.

Dual Output

Two valuable products from one process with significant environmental benefits. The resulting syngas serves as industrial fuel and feedstock for synthetic fuels and chemicals. Activated carbon becomes a premium material for several applications in e.g. water and gas purification.

carbon monoxide

From fossil-based fuels to electrified CO₂ conversion enabling sustainable operations

Fossil fuel use can be reduced by directly replacing fossil-based carbon sources with carbon-neutral carbon monoxide, or by converting that CO into synthetic hydrocarbons that can substitute conventional fossil fuels. In both approaches, carbon dioxide is no longer treated as waste, but is transformed into a usable feedstock or energy carrier for fuels and chemicals.

A key enabler is electrically heated CO₂ reduction, which allows CO production without combustion and hydrogen use. The resulting carbon monoxide can then be used as fuel in conventional combustion-based systems, enabling the indirect electrification of these processes: electricity is first used to produce CO, which then serves as a combustion-compatible energy carrier.

The resulting carbon monoxide can be utilized in existing industrial systems, including synthetic fuel production, chemical manufacturing, and energy generation, without major changes to downstream infrastructure. This makes CO₂-derived CO a scalable pathway for reducing emissions in hard-to-abate industries.

Carbon Monoxide

Uses of Carbon Monoxide

Synthetic Fuels

CO combined with hydrogen forms syngas, from which synthetic diesel, methanol, and other e-fuels are produced for aviation and maritime transport.

Steel Reduction

CO acts as a reducing agent in iron production, enabling lower-emission steelmaking by replacing part of the coke used in blast furnaces.

Chemical Industry

Carbon monoxide is a key feedstock in the production of plastics, pharmaceuticals, and other synthetic hydrocarbons.

Circular Economy

Reduciner directly converts industrial CO₂ emissions into CO — a closed loop where carbon is not released into the atmosphere but reused as a resource.

Enabling low carbon operations

From fossil based to biogenic activated carbon and from combustion to electrification

Activated carbon is a highly porous material that effectively captures impurities, odors, and chemical compounds. It is widely used in water and air purification, as well as in industrial processes where reliable filtration and purity are required.

Its exceptionally large surface area (BET >1000 m2/g) enables efficient adsorption of unwanted substances, helping improve safety, performance, and overall product quality.

We produce biogenic activated carbon from renewable biomass sources, offering a sustainable alternative to fossil-based materials. Unlike fossil-derived activated carbon, our product is based on the short carbon cycle, helping to significantly reduce lifecycle emissions depending on sourcing and production energy.

The result is high-performance activated carbon with the same adsorption efficiency, but a stronger sustainability profile supporting companies, cities and communities in reducing their carbon footprint and meeting increasingly strict ESG and regulatory requirements.

Active carbon

Uses of Active Carbon

Water Filtration

Activated carbon is widely used in drinking water and wastewater treatment to remove impurities, chemicals, and heavy metals.

Energy Storage

High-surface-area activated carbon is a key material in supercapacitors — a fast-growing market driven by electric vehicles.

Air Purification

In industrial facilities, hospitals, and buildings, activated carbon filters effectively remove volatile organic compounds (VOCs) and odours.

Pharmaceuticals

In pharmaceutical production and medicine, activated carbon is used to purify substances and treat poisoning cases.
