Enso — National B2B Marketplace to Buy and Sell Surplus Industrial MaterialsCircular Materials Marketplace
The National B2B Platform for Buying and Selling Surplus Industrial Materials
The industrial surplus marketplace that turns your waste streams into revenue. Sell surplus industrial materials, reclaimed aggregates, and industrial byproducts — or source bulk recycled materials from verified suppliers across the USA.
Turning Waste Into Opportunity
Enso is a woman- and minority-owned B2B circular economy marketplace — a sustainable materials procurement platform that connects companies holding surplus industrial materials with buyers who need them. Whether you want to sell industrial waste online or source repurposed industrial materials, Enso is the industrial materials exchange built for the circular economy.
Waste Streams → Commerce
Our patented platform matches industrial byproducts with qualified buyers across the USA. Categories include: spent grain, reclaimed asphalt, recycled concrete, recycled aggregate, scrap metal, excess packaging, used pallets, demolition debris, industrial chemicals, food-grade byproducts, textile waste, and more.
Disposal Costs → Revenue
Sell surplus industrial materials and reclaim value from inventory you’d otherwise pay to dispose of. Buyers on our surplus materials trading platform access cost-effective, sustainable alternatives to virgin inputs.
Full-Service Matching
From listing to transaction, we handle vetting, logistics, compliance, and quality assurance — making circular procurement as straightforward as any conventional purchase.
Verified Impact
Every transaction generates a Midori Metrics® scorecard: emissions avoided, water saved, waste diverted, and cost savings.

Midori Metrics®
Midori Metrics® is a sustainability impact tracking tool. It provides buyers and sellers with environmental scorecards that track, visualize, and quantify the benefits of their circular transactions.
Midori Metrics® supports internal ESG dashboards, regulatory reporting, grant applications, tax credits, and stakeholder communications. Each listing includes a scorecard scaled to the buyer's requested quantity.

Environmental impact report generated per transaction, scaled to quantity.
Greenhouse gas emissions prevented per transaction cycle
Gallons of water conserved versus virgin material production
Tons of material diverted from landfill per matched listing
Estimated kilowatt-hours saved versus virgin extraction
Tons of virgin aggregate or equivalent materials avoided
Estimated carbon credit value and cost savings per transaction
Sample metrics shown above are illustrative. Actual Midori Metrics® scorecards are calculated based on material type, quantity, and transaction-specific data using globally recognized standards.
