To enhance waste-to-resource initiatives in Canada, ClimateDoor facilitated a partnership for Proteus Waters with C-Green, aiming to convert organic waste, like sewage sludge, into valuable resources while minimizing greenhouse gas emissions.
To address Canada’s organic waste management challenges by transforming sewage sludge into hydrochar, contributing to the circular economy and offering sustainable resource solutions.
Proteus faced limitations in securing reliable waste-to-resource technology. Additionally, complex funding and regulatory hurdles needed to be navigated to launch a successful pilot in Canada.
ClimateDoor’s strategy enabled Proteus Waters to form a transformative partnership with C-Green, aligning with Canada’s goals for waste management and emissions reduction. This collaboration supports the circular economy and establishes Proteus as a leader in sustainable waste solutions.

We work with climate ventures at TRL 6–9 that have early traction and are ready to grow. If you’re looking to raise capital, land partners, or enter new markets, we can help.
Think of us as extensions of your core team, in the trenches executing and delivering in the key areas we excel the most in. Whether that’s building sales materials, updating your financial model, closing investment, securing partnerships, our team is your team, and we’re more of a “less talk, more work” shop.
Not from the beginning but may longer term. We believe taking equity is like getting into a marriage with someone, and we want to date first to ensure it makes sense for both parties to continue longer term.
We’re doers, not advisors, keeping our hands on keyboards to deliver and execute where you need surge capacity support the most, which typical accelerator programs and the like will not provide such level of detailed / hand-on support.
The timeline varies depending on the scope of the project and the services provided. Typically, you can expect to see significant improvements within 3-6 months, with some immediate benefits as we begin implementation.
Clean economy executives, change-makers and investors welcomed.
Tailored insights and opportunities await.
