  • BLUUMBIO
    BLUUMBIO
    Y Combinator LogoS2021
    Active • 4 employees • Berkeley, CA, USA
    Our mission -To ensure current and future generations have access to clean soil, water & air. -To protect and restore earth's beautiful and diverse ecosystems. -To undo the harm of industrial activity on the planet and ensure future industrial activities are more sustainable. Our research -We develop new bio-based solutions that break down and remove toxic chemicals from the environment.  We also develop bioreactor based solutions which remove toxins from industrial production pipelines, ensuring contaminants are never released into the environment. -To do this, we've partnered with Nature. Specifically, we have harnessed the power of one of Nature's smallest but most powerful technologies: enzymes. Enzymes are everywhere. They break down the food in your stomach, remove dirt from your clothes, and make our beer. At BluumBio, we look for enzymes found in bacteria, algae, plants and other living organisms that naturally degrade toxic chemicals. We then make these enzymes work better in the lab and come up with develop new applications for these technologies.
