Brimstone low carbon cement is produced from calcium silicate rock. Unlike limestone, which is the conventional raw material used in cement production and releases a significant volume of CO2 when processed, calcium silicate doesn’t release CO2. Brimstone produce two products: ordinary Portland cement (OPC) and supplementary cementitious materials (SCM). In addition to the calcium, silicon, iron and aluminum used to make cement, calcium silicate rock contains magnesium. They use this magnesium to passively and permanently remove atmospheric CO2. Image Brimstone.

Boston Metal have developed an electrolytic process, molten oxide electrolysis (MOE), which enables the use of renewable energy sources in the production of steel. This direct approach eliminates several steps in the steelmaking process and does not require coke production, iron ore sintering and pelletising, blast furnace reduction or basic oxygen furnace refinement. Image BMW Group, who have invested in Boston Metal.

InventWood have created a type of compressed wood they call MettleWood, suitable for demanding load-bearing applications. The process involves dismantling the lignin that bonds the cellulose fibres. This softens the wood and allows the cellulose fibres to be packed more tightly via evaporation of the water content. The wood is then swelled with water in a rapid process that “shocks” it to form a distinct partially open, wrinkled cell wall structure that provides space for compression as well as the ability to support high strain. The wood is compressed, finished and sealed to form the final profile. The process significantly increases strength and stiffness, which the company claims makes it more competitive with structural metals such as steel and aluminium alloy. Image InventWood.

Woodoo Augmented Wood uses a patented process to remove lignin from wood and replace it with a bio-based polymer (probably polyurethane).

Hydrogen and oxygen are produced as byproducts. They are in development and currently scaling up the technology to industrial-scale production. Image SublimeSystems.

Inspired by the composition of coral and seashells, Prometheus Materials combine microalgae (biomineralizing cyanobacteria that are grown using sunlight, seawater, and CO2) with other natural components to produce biocement and bio-based concrete – they are developing a patent-pending photosynthetic biocementation process. They already produce microalgae-based concrete masonry units (CMU) that conform to American Society for Testing and Materials (ASTM) standards and are planning to introduce pre-cast and ready-mix products for roofing tiles, wall panels, sound barriers, and other concrete elements. Image Prometheus Materials.

Concrete4Change (C4C) is developing additive materials for concrete that act as carbon carriers. Recycled wood and plastic waste are prepared to become an ‘adsorbent’ that may capture and release CO2. Then, using a process unit, the carrier is loaded with carbon dioxide – mainly utilising CO2 captured from the carbon heavy flue gas from cement production as feedstock. This loaded carrier is mixed into either wet or dry concrete wherein it slowly releases the CO2, allowing for permanent mineralisation. Not only does this mineralisation make the concrete stronger, less cement is required to do the same job. With this technology, C4C also promises 10 times more carbon sequestration than existing approaches for ready-mix concrete. Image Concrete4Change.

Made of Air convert biomass waste streams (such as forestry offcuts and secondary agricultural materials), which have photosynthesised CO2, into a form of biochar through controlled pyrolysis. Burning materials without oxygen means the carbon cannot form CO2 and instead forms biochar. Using their technology the biochar is converted into a functional carbon-rich filler for plastic biocomposites. Biochar has been produced for centuries and is increasingly being used as a fertiliser as well as a way of sequestering carbon in the soil, because the carbon is locked in and it remains stable for hundreds of years.

Limestone calcined clay cement (LC3) cement produces 30-40% less CO2 emissions compared to regular cement. The reduction is achieved by partially substituting (20-70%) clinker with calcined clay and limestone. This allows for a lower firing temperature and avoids the decomposition of limestone, which is responsible for a significant proportion of the CO2 of cement production. Clay is calcined (heated to around 800 degC, as opposed to 1,450 degC for regular cement) to make it suitable. It is widely available and compatible with modern cement manufacturing processes. While clinker is a waste product from burning coal and steel furnaces, it is not always available close to the cement factories, and the processes that generate it have come into question over sustainability concerns. Developed by Prof Karen Scrivener from EPFL in Switzerland and Prof Fernando Martirena from UCLV in Cuba, supported by the Swiss National Science Foundation (SNSF) and the Swiss Agency of Development and Cooperation (SDC). LC3 is in commercial production in several cement factories around the world. Image LC3.
