Operations are expected to commence towards the end of 2025, featuring an integrated, digitalised, and circular plant design​​.

8. Sublime Systems

Revenue: US$45.86m

Sublime systems has a unique approach to climate change as it targets the cement industry for decarbonisation. The industry is responsible for 8% of global greenhouse gas (GHG) emissions and production typically requires high-temperature kilns that burn fossil fuels. 

The climate tech startup was co-founded by an MIT Professor Yet-Ming Chiang and Dr Leah Ellis. The technology is expected to reduce production emissions by 50% without altering cement’s properties or impacting the functionality of the product.
