Helix Carbon aims to cut steel emissions by upcycling blast furnace CO2
Helix Carbon, a startup presenting at TechCrunch Disrupt, has developed a technology to reduce carbon emissions from blast furnaces by converting waste carbon dioxide into carbon monoxide, which is then recycled back into the furnace. This process could reduce the need for coke, a major source of emissions, saving iron producers up to $14 per ton while cutting emissions. The company plans to initially target the specialty chemicals industry for revenue, using the same technology to create chemicals on-site from waste streams. The steel and iron market is valued at $2 trillion.

EveryCarbon wins FLAIR subcontract to scale materials production
EveryCarbon, a manufacturer of high-performance shielding materials, has won a subcontract under the FLAIR project, led by TU Hamburg, to scale its circular diol production from lab to a 10,000-litre industrial pilot at Popp Feinkost. The project aims to validate the industrial-scale production of ECOne, a polyester insulation material, using food waste hydrolysate and existing infrastructure. This initiative supports the shift to fossil-independent manufacturing and involves partners such as the University of Hamburg and Fraunhofer IPA for monomer development and data analytics. The project is a multi-year effort to convert food-processing side-streams into functional materials.
Atoco Startup Turns Data Center Waste Heat into Drinking Water
California-based startup Atoco has developed a system that extracts drinking water from the air using waste heat from data centers. In a September demonstration in Irvine, the company used 65°C heat to simulate server exhaust and produced water from its machine. The technology relies on metal-organic frameworks (MOFs), developed by Nobel laureate Omar Yaghi, which can capture water vapor even at low humidity. The demo unit delivers up to 300 liters per day using the waste heat of a 20 kW data center. A commercial unit with 1,000 liters per day capacity is in development, with first orders expected by year-end. Atoco has held five prototype tests with partners in the US and Gulf states and is in talks with tech giants. Costs are currently around $5 per ton of water, higher than desalination, but expected to drop in 3-5 years.
EU-Startups Analysis Shows 20 Startups in €3.4B EU Net-Zero Funding
EU-Startups' research reveals that 20 of the 77 European net-zero technology projects selected for €3.4 billion in EU Innovation Fund support involve startups, scaleups, and younger technology ventures. Announced on 19 October 2026, the European Commission's selection covers projects across 23 countries in the European Economic Area, spanning clean energy, industrial manufacturing, carbon removal, sustainable fuels, and critical raw materials. The startup-associated projects represent about 26% of the total selection. Notable startups include Vaeridion (electric aircraft), GravitHy (green steel), ChainCraft (circular chemistry), traceless materials (plastic alternatives), and Reverion (reversible power plants). The projects could collectively avoid approximately 290 million tonnes of CO₂-equivalent emissions in their first ten years. The programme is financed through EU Emissions Trading System revenues. Final grant agreements are expected by Q1 2027.
