Reduce plastic & CO₂ pollution for a liveable future

“I have spent my career in the packaging industry, where I became very aware of the impact packaging materials have on the environment. I then decided I had to dedicate the rest of my life to reducing that impact. During my time as a consultant at my own company, I explored bio-based packaging solutions and fell in love with mycelium.”

“I was working at my own production company for prosthetics when I started making changes to live more sustainably. I knew I wanted to align my career with my values, so I started working in sustainable energy and eventually became co-founder of Grown.bio.”
After losing touch when we were 22, our paths crossed again 25 years later. What connects us to this day is our passion for sustainability and dedication to creating a liveable future for our children and generations to come.
Join us in creating a liveable future.
Our next step is to build a factory that can produce 10 million packages each year.
It’s pretty obvious we’re into sustainability, but did you know that we also strive to be socially sustainable? We believe that a balance in diversity is essential at all levels of our organization. If possible, we employ people with a distance to the labor market, who have faced barriers to employment and, offer opportunities for professional development and growth.
