Simple enough to
actually work.

01
🏪
Businesses list their streams

Coffee shops, breweries, restaurants, woodworkers — any Winnipeg business with a consistent waste stream gets a free listing. We handle the setup, you handle the handoff.

02
🔍
Recipients browse and claim

Urban gardeners, makers, small food producers, and community orgs browse available streams by category, neighbourhood, or material. Find what you need and reach out directly.

03
🤝
The match happens locally

No platform fees, no accounts, no middleman. Just two Winnipeg parties figuring out a pickup that works for both. Material stays in the city, out of the landfill.

Every industry
has a stream.
