Kore Infrastructure
We’re in the middle of an electron race, and the bottleneck isn’t ambition. It’s buildable power. Kore Infrastructure turns landfill waste into firm, dispatchable, carbon-negative electrons using a proven, closed-loop, non-combustion pyrolysis system. Turn on the landfill. Where waste sits, power starts. Landfills aren’t just a climate liability. They’re grid-adjacent industrial sites with real-world advantages: existing operations, local logistics, plentiful feedstock, and proximity to load and transmission. Kore Infrastructure converts that overlooked footprint into repeatable power plants that are built for speed, scaled through modular deployment, and designed for the realities of permitting and uptime. Landfills are Future Power Plants. What we deliver: Firm power you can actually buy (not just model). Carbon-negative outputs: clean biogas + stable biocarbon for permanent sequestration. A scalable platform that grows site-by-site, region-by-region. Our customers and partners are the builders of the next decade of infrastructure: energy buyers, developers, and operators who care about one thing: getting reliable electrons online, faster. If you believe the transition will be won by execution, not slogans, you’re in the right place.
