Lime Production
Decarbonizing value chains and improving
performance for better industries, a better
climate and a better future.
Unlocked Circularity, Reduced Waste, Increased Profits
CarbonBlue develops technologies which increase industrial efficiency, productivity and profits, while unlocking circularity and reducing reliance on legacy fuels.
Our Technology
Electrified, Scalable,
Sustainable
CarbonBlue’s EcoLime technology is a patented, easily-deployable, fully electrified lime production process capable of using low-quality waste feedstock. Operating at ambient temperatures, EcoLime replaces kiln combustion with clean energy, while unlocking circularity and upcycling of waste streams and low-quality feedstock, enabling sustainable, high-quality production of one of the most utilized materials on the planet.
Solutions
EcoLime allows steel producers to get more out of their slag. By reclaiming lime from slag for circular use in steel purification, EcoLime reduces emissions, external lime consumption and waste management, shortens supply chains, and increases profits.
EcoLime produces high-quality lime from diverse feedstocks, regardless of feedstock purity. Able to extract lime from on-site waste streams like quarry fines, demolition, and steel slag, EcoLime can shorten supply chains and lower feedstock prices, enabling high-quality PCC production from previously untapped lime sources
EcoLime unlocks on-site biogenic CO2 production, reduces the need for expensive CCS, and decarbonizes the lime reclamation stage in Kraft process mills. Fully electrified, EcoLime eliminates the need for fuels, and further reduces energy and heat requirements by bypassing the need to dry lime-mud, as well as reduces loss of sulfides and their required makeup streams.
EcoLime extracts lime from low-quality calcium-bearing materials like construction and demolition (C&D) waste for on-site reuse or commercial production.
