About
Leilac is a 93%-owned subsidiary of ASX-listed Calix Limited that develops indirectly heated electric calcination technology primarily for decarbonising cement and lime production. Its CDR relevance derives from a perpetual, exclusive global licence with Heirloom, which uses Leilac’s electric kiln to separate CO2 from limestone in its DAC process β including the ~17,000 tpa Shreveport facility targeted for 2026 and a follow-on ~300,000 tpa plant. Cement/lime decarbonisation remains Leilac’s core business; DAC royalties are an adjacent revenue stream.
