"Calgary-based CleanO2 transforms CO2 captured from building heating boilers into feedstock to make soap. Newlight Technologies, a biotechnology startup based in California, takes carbon pulled directly from the air and turns it into biodegradable plastics. Germany’s Covestro AG, one of the world’s largest polymer manufacturers, is also switching some of its fossil fuel-based feedstocks to carbon-derived materials for everything ranging from car shells to medical devices and stadium roofs."

"Both water and captured carbon can be used to make sustainable aviation fuel. That was particularly attractive to investor JetBlue Ventures, the venture capital arm of the airline, which invests in companies attempting to change the travel industry."

"Eidelson emphasizes that while Stepchange is driven by what he sees as a moral imperative — working as fast and aggressively as possible to slash carbon from every sector of the economy — he also expects it to succeed financially."

"Other firetech startups include Overstory, which is using AI to work with utility companies to analyse satellite data and identify wildfire risk from vegetation growing near power lines. California-based Rain is working with fire agencies to use autonomous drones that use sensors to identify fires before they rage out of control. Software and thermal cameras also allow them to fight the fires from the air."

"The company’s new EV product is expected to feature materials including soybean oil used in the tire’s construction as well as sustainably sourced natural rubber as well as high-quality rice husk ash silica, which is a byproduct when rice is processed."

"Exaum’s innovation balances the production and consumption of electricity along the power grid, an issue for generators and customers as more intermittent renewable energy is deployed. The technology allows the transmission system operator to adjust and control electricity consumption in the grid, while ensuring that sudden changes in production do not cause blackouts or grid imbalance. It can direct and channel excess power production to areas where it’s needed, such as industrial heating—an area of need in Finland."
