Manufacturing & Processing

Clean, scalable, microbe-made colour to replace toxic dyes

Molecule Works Inc. logo

Molecule Works Inc.

Manufacturing & Processing

We are developing a low-cost (less than $100/ton) solid sorbent DAC system based on our proprietary reactor/contactor configuration. This design yields very high productivity by delivering low pressure drop, very high heat and mass transfer rates and high sorbent loading. Heat is provided through ls closed loop low temp hot water system so that no steam is needed. After initial charge, no water is consumed. Regeneration is achieved in 20 to 30 minutes.

[ 03 ]Who We Are

Greentown is a 501(c)(3) nonprofit helping climate entrepreneurs build faster.

The way the world makes energy, materials, and food is changing — and the next decade will decide whether that change makes life better: more energy with fewer emissions, more industry with cleaner air, more good jobs.

That future comes from entrepreneurs — the heroes who turn ideas into real products, real companies, and the jobs of the future. And the ones who make it are the ones with a community behind them.

For 15 years, Greentown has been that community — leaning in with the space, the people, the funding, and the first customers they need. Get behind the entrepreneurs building our future.
