Recycling & Circular Economy
WALL-E tech — AI-powered waste sorting and material recovery
Robotic waste sorting, AI-driven material recovery, chemical recycling, and food waste transformation. Companies in this sector are making recycling dramatically more efficient — turning the garbage dump into a mine, and landfill into energy.
Why It Matters
Humanity generates 2 billion tons of municipal solid waste per year, projected to reach 3.4 billion by 2050. Traditional recycling relies on error-prone manual sorting, and roughly 91% of plastics ever produced have never been recycled. A new generation of AI-powered robots can identify and sort hundreds of materials per minute with superhuman accuracy. Combined with breakthroughs in chemical recycling (breaking plastics down to their molecular building blocks) and enzymatic processes, this sector represents the infrastructure for a true circular economy. Think WALL-E — but profitable, at scale, and happening now.

Companies in Recycling & Circular Economy
6 trackedAMP Robotics
Series C ($300M+, backed by Blue Earth Capital, Microsoft Climate Innovation Fund)
AI-powered sorting robots deployed at 200+ recycling facilities. Their neural networks recognize 100+ material categories at 80+ picks per minute per arm — dramatically more accurate and faster than human sorters. The AMP Neuron platform is essentially the brain of modern recycling.
Deployed AI sorting systems at 200+ facilities across North America; processes over 2 billion items per year
Glacier
Series A ($16M, backed by NEA, New Enterprise Associates)
YC-backed startup building lower-cost recycling robots designed for mid-sized materials recovery facilities (MRFs) that can't afford traditional industrial sorters. Their robots install on existing conveyor lines and use computer vision to sort plastics, metals, and paper.
Deployed robots at recycling facilities across California and the Midwest; targeting the underserved mid-market MRF segment
ZenRobotics
Subsidiary (Terex)
Finnish pioneer of heavy-picker recycling robots for construction and demolition waste — handling materials up to 30kg that humans can't safely lift repeatedly. Acquired by Terex (NYSE: TEX) and deployed across Europe and North America.
First commercial waste-sorting robots; Heavy Picker handles C&D waste at scale across 50+ installations globally
Mill
Series B ($100M+, backed by Breakthrough Energy Ventures)
Founded by Nest co-founder Matt Rogers. Mill's kitchen bin dehydrates and grinds food scraps into nutrient-rich grounds that are mailed back to farms as chicken feed, closing the food waste loop at the household level. Beautiful design, subscription model.
Launched consumer product in 2023; diverting tens of thousands of tons of food waste from landfills annually
Carbios
Public (Euronext)
French company pioneering enzymatic PET plastic recycling — using engineered enzymes to break plastic bottles back into their raw molecular components, enabling infinite recycling without quality degradation. Partnered with L'Oréal, Nestlé, and PepsiCo.
Building world's first industrial-scale enzymatic PET recycling plant in France; commercial production targeted for 2026
Novoloop
Series A ($21M, backed by Valo Ventures)
Upcycles hard-to-recycle polyethylene plastic waste into high-performance thermoplastic polyurethanes (TPUs) used in footwear, automotive, and electronics. Partners with On Running and other premium consumer brands.
First commercial products incorporating upcycled PE-derived TPU launched with On Running; industrial scale-up underway
