Recycleye’s £40 treadmill became a business that picks through your rubbish
A camera, an eBay treadmill and some borrowed garage space started Recycleye. Its robots and optical sorters now tackle recycling’s awkward arithmetic: recovering materials has to pay.
The 5 Million-Stop Machine Turning Trash Into Infrastructure
Republic Services makes roughly 5 million pickups a day. Behind each stop is a carefully linked business of routes, landfills, laboratories, recycling plants and energy projects - an unglamorous network becoming a platform for circular materials.
Revise Robotics
Revise Robotics builds AI-enabled robotic systems that test, refurbish, and resell used electronics, starting with laptops. Its machines slot into e-waste recycling and IT asset disposition facilities, where they inspect devices, wipe drives, photograph units, and list them on online marketplaces - hundreds of laptops a day, across any model, manufacturer, or operating system, without human intervention. Founded in 2024 by Rupesh Jeyaram and Antonio Monreal and backed by Y Combinator (W25), the New York company aims to unlock the residual value trapped in discarded electronics and keep more devices out of landfills.
Goodwill Industries of South Florida
Goodwill Industries of South Florida is a Miami-based nonprofit social enterprise that funds training, employment and job placement for people with disabilities and other barriers to work. Founded in 1959, it runs a self-sustaining business model spanning donated-goods retail and thrift stores, technically complex apparel and flag manufacturing for the U.S. military, commercial laundry, janitorial services and third-party logistics. With roughly 3,600 employees and about $196M in annual revenue, it is one of the largest Goodwills in North America and the largest employer of people with disabilities in Florida.
Planet Protector Group
Planet Protector Group is an Australian climate-materials company that turns waste wool and recycled fibre into circular insulation. Its flagship WOOLPACK product replaces polystyrene in cold-chain packaging for food, wine and pharmaceuticals, while a newer building-insulation line extends the same wool, denim and recycled-poly technology into construction. Founded in 2016 by Joanne Howarth, the company has diverted thousands of tonnes of waste wool from landfill, eliminated millions of polystyrene boxes and returned millions in new revenue to sheep farmers across Oceania.
Rekosistem
Rekosistem is a Jakarta-based clean- and climate-tech company that manages Indonesia's fragmented waste supply chain end to end. Through a network of Reko Waste Stations, app-based pickup services, and material recovery hubs, it collects, sorts, and channels waste from households and businesses back into the circular economy. Founded in 2021 by Ernest Layman and Joshua Valentino, the company serves 90,000+ households and 200+ enterprise clients, processes roughly 4,500 tonnes of waste per month, and raised a US$7M Series A in 2025 led by Saratoga Investama Sedaya and K3 Ventures.
6K
6K is a North Andover, Massachusetts advanced materials company that uses its proprietary UniMelt microwave plasma technology - which reaches roughly 6,000 degrees, hence the name - to produce battery cathode materials and additive-manufacturing metal powders faster, cleaner, and with fewer processing steps than conventional methods. Spun out of research at MIT and the University of Connecticut, the company operates through two divisions, 6K Energy (battery cathode active materials) and 6K Additive (sustainably sourced metal powders), and is building a domestic U.S. supply chain for critical materials backed by federal grants and more than $348 million in venture funding.
CurbWaste
CurbWaste is a New York-based vertical SaaS platform built for independent waste and dumpster haulers. Founded by fourth-generation hauler Mike Marmo, it unifies order management, online ordering, real-time dispatch, driver mobile apps, inventory and asset tracking, automated invoicing and payments, and data reporting into a single cloud system. The platform aims to become the system of record for the fragmented waste industry, serving roughly 150 haulers across 40 states, and raised a $28M Series B in October 2025 to expand AI-driven route optimization and business intelligence.
Downstream
Downstream is a Dallas-based online marketplace that lets construction contractors rent equipment, book waste hauling, and order jobsite services - dumpsters, porta potties, scissor lifts, forklifts, fencing, mobile offices - from a nationwide network of vetted suppliers. The platform delivers real-time pricing, multiple competing quotes per job, consolidated billing, Net 30 payment terms, and AI agents that read a contractor's rollout sheets or invoices to procure automatically. Founded in 2022 (originally as Trash Gurus), the company raised an $8M Series A in November 2025 co-led by Brick & Mortar Ventures and Moneta Ventures.
RoadRunner
RoadRunner (RoadRunner Modern Waste + Recycling) is a Pittsburgh-based, technology-driven waste and recycling company that helps commercial and enterprise businesses cut costs, divert more material from landfills and report on their environmental impact. Founded in 2014 by Graham Rihn, it pairs a managed-services model with proprietary software and AI-powered smart cameras (via its 2022 acquisition of Compology) to meter, monitor and optimize waste streams. The company serves 14,000+ customers across all 50 states and has raised roughly $150M in venture funding.
Graham Rihn
Graham Rihn is the founder and CEO of RoadRunner, a Pittsburgh-based company that uses data and AI to modernize commercial waste and recycling. A Cornell economics grad and former college linebacker who grew up in Allison Park, Pennsylvania, Rihn started RoadRunner in New York City in 2014 after watching garbage pile up on Manhattan streets and asking why an $85 billion industry had skipped the technology revolution. He moved the company to his hometown of Pittsburgh in 2017 and grew it from roughly 30 people in three cities to more than 500 employees serving over 12,000 customers nationwide, raising more than $150 million along the way, including a $70 million Series D led by General Atlantic.
Philip Stanger
Philip Stanger is the co-founder and CEO of Olyns, a Silicon Valley startup turning recycling into a self-funding business by pairing AI-powered reverse vending 'Cubes' with retail media advertising. A classically trained musician with degrees from Johns Hopkins and Yale, he scored films before founding indoor-positioning startup Wifarer, then led Apple Maps' indoor mapping team for five years. He started Olyns in 2019 after watching wildfires and floods hit the Santa Cruz Mountains where he lives, betting that recycling fails not for lack of technology but because its business model is broken.
Hauler Hero
Hauler Hero is a New York-based software company building a cloud and AI-powered operating system for waste and recycling haulers. Its all-in-one platform unifies CRM, dispatching, routing, billing, reporting, and a driver mobile app, replacing the decades-old tools that most trash and recycling companies still run on.

Glacier
Glacier builds AI-powered robots that sort recyclables inside Material Recovery Facilities (MRFs). Their compact, conveyor-mounted robots use computer vision trained on billions of recycling images to identify and pick more than 70 material categories, while also generating real-time data on what flows through the waste stream - data that brands and recyclers use to prove and improve circularity.
Rebecca Hu-Thrams
Rebecca Hu-Thrams is the co-founder and CEO of Glacier, a San Francisco-based company building AI-powered robotic arms that sort recyclables in material recovery facilities. Raised by Chinese immigrant parents who instilled a 'reduce, reuse, recycle' ethos, she channeled her Bain consulting background and Thumbtack operating experience into tackling what she calls 'the most demented form of manufacturing on the planet.' Glacier's robots, trained on 3.8 billion images of waste, sort 70+ material categories at 60 picks per minute - preventing roughly 10 million items per robot from reaching landfill annually. Named Fast Company's #1 Most Innovative Company in Robotics & Engineering for 2026, Glacier has raised $33.2 million including a $16M Series A extension in April 2025 backed by Amazon's Climate Pledge Fund and New Enterprise Associates.
