Oferta tecnológica: Novel mechanochemistry for simultaneous decarbonisation and solid waste valorisation in the cement industry

General information

Short Summary
The UK arm of a multinational SME is close to market with a novel mechanochemistry that mineralises CO2. Its technology transforms CO2 and byproduct feedstocks, at ambient temperatures into supplementary cementitious materials to abate clinker in cement or cement in concrete. Companies that make cement or produce/have large amounts of CO2, fly ash, steel slag or other industrial byproducts are sought for commercial agreements with technical assistance.
Full Description
Being a large CO2 emitter, the cement industry has started trialling new technologies. This includes solutions that reduce clinker in cement mixes like the use of low carbon feedstocks. However, these solutions are not problem-free as said feedstocks need to be of good quality and are not always logistically viable for cement producers.
The UK arm of a multinational SME is delivering new technology to the cement industry and other heavy industrial producers who produce either large amounts of CO2 or large amounts of industrial byproducts.
Its technology leverages a proprietary mechanochemical process that starts with feedstock that until now has been classified as waste or byproduct, and flue gases from the flue stack. Byproducts like fly ash, bottom ash, and steel slag are milled and contacted with the flue gases in a special reactor, permanently binding the CO2 in the gases to the material. The end product is an enhanced SCM or supplementary cementious material to be used directly in cement production. The strength of the SCM is typically of or above industry standards meaning it can replace a large proportion of clinker in the cement. The combined effect of abating clinker in cement and carbon sequestration means that a tonne of the new blend emits up to 60% less CO2, compared to ordinary portland cement.
The reaction is being trialled at TRL 8 with global leading cement manufacturers utilising glass, reclaimed ashes, and alternative slags. The reaction seems to work for a wide range of starting materials. The company claims to have third-party validated more than 40 materials across North America, Europe, and Asia, in its process.
The company seeks partnerships for both market adoption and new process development under commercial and technical agreements.
Advantages and Innovations
The patented mechanochemistry runs at ambient temperatures and can be fed with renewable energy.
The advantages are manifold. In essence, the technology forms a circular economy loop by providing a CCUS (carbon capture and utilisation) and solid waste management solution to other industries, and an end-to-end decarbonisation solution to cement. The product can be used for cement manufacturing or selling on as an SCM.

Partner Sought

Expected Role of a Partner
Type of partner sought: industry.
Specific area of partner sought: manufacturers of cement or industries emitting large volumes of CO2 who have access to newly created or stored/landfilled industrial byproducts.
Role of partner sought: interested parties are invited to send a description of composition of feedstocks. The UK company can then comment on the TRL where joint development can start from, whether technical or commercial.
