Credit Stack.
Making biowaste sorting and recycling economically viable.
A product that connects global funding to food and organic waste diversion from landfills to biological treatment and rewards the people who do the work.
How It Works · Part 2
A less polluted and cooler planet needs more than good intentions.
The Credit Stack combines recycling and carbon credits from the same verified recycling activity. They are sold together and retired separately, keeping the two environmental claims distinct.

What it funds
Recycling credits help scale and sustain biowaste collection and recycling.
Together, these funding roles underpin the Biowaste Financing and Policy Roadmap.

Your purchase can help activate the market for diverting biowaste from landfills to biological treatment. Demand for verified outcomes helps fund local projects and accelerate the adoption of biological treatment.
Map key, sources and records
Carrot projects · July 2026 snapshot. Project status does not establish credit availability.
Climate TRACE · 2025 annual methane estimates.
Locations are approximate. Accredited projects are named. Projects under audit show municipality only. The development pipeline is a count, with no locations plotted. The selected landfill sites cover 12 South American countries and show potential need for recovery; they are not Carrot projects or available credits.

Your purchase helps fund local recovery—and helps this market get started. Today, less than 1% of municipal waste in Latin America and the Caribbean is biologically treated.World Bank — What a Waste 3.0
Compare the records, symbols and claims
| What to check | Recycling | Carbon |
|---|---|---|
| Certificate | RecycledID | GasID |
| Credit symbol | C-BIOW | C-CARB.CH4 |
| Environmental claim | Certified material recycling | Quantified emission reductions |
| Retirement | A separate recycling-credit record | A separate carbon-credit record |
MassID records the material and its custody. RecycledID and GasID are certificates backing the credits. The carbon path uses MassID evidence independently of recycling-credit issuance.
Retirement removes a credit from circulation so it cannot be resold or used again. The two paths do not create permission to claim the same emissions twice. This page invites a contribution to verified results; it makes no carbon-neutrality or compliance promise.
The system changes. When the rewards are shared.
Buying credits funds real outcomes and shares proceeds with the people doing the work—including the waste generator, where it starts and needs to be sorted.

Rewards are shared transparently
A credit purchase funds shared rewards across these six contribution groups.

The Rewards Distribution Policy defines the participant categories and the payout ratio for each. Rewards depend on waste type, verified contribution and the applicable policy.
Rewarding environmental work creates an economic incentive to change.
