Best Solid Waste Management Tech Companies in United States

The 445 best Solid Waste Management Tech companies in United States in 2026, ranked by funding and momentum. Funding, investors, founders, valuation, tech stack and live signals. Top: Redwood Materials.

$11.3Bdisclosed funding

214have raised

Ranking the top Solid Waste Management Tech companies in the United States by disclosed equity funding, this directory covers 445 tracked firms carrying a combined $11.3B in disclosed capital. That's real money. The global solid waste management market sat at roughly $285.2B in 2019 and is forecast to reach $379.1B by 2028, compounding at 3.3% annually, driven by urbanization, rapid industrialization, and IoT-enabled smart collection systems. Four unicorns have emerged from this field, and if you want a sense of scale, consider that Redwood Materials alone has pulled in $1.9B, while Divert has raised $1.0B. Those two firms aren't outliers so much as anchors for a sector that's attracting serious institutional attention.

What I find telling is where the funding concentrates. LanzaTech sits at $869M, well above the pack behind the top two, and the investor mix, anchored by the National Science Foundation and America's Seed Fund alongside Plug and Play Tech Center, signals that deep-tech credentials matter here as much as commercial traction. Hot themes across the sector now include EV battery technology and next-generation EV platforms, reflecting how waste recovery and electrification supply chains are increasingly the same conversation. So the directory below isn't just a fundraising leaderboard. It's a map of where materials recovery is actually being built.
