I have been an Environmental Engineer for over 50 years. It all started when I was 19 and Purdue set me up with 3 professors and together we developed an individual engineering program to become an environmental engineer. When I was 23 I was the senior technical representative on two wastewater treatment design teams for chemical plants. At 29, I wrote my first book, “Groundwater Treatment Technology”. For the next 30 years I wrote, taught and designed treatment systems for groundwater and soil all over the world. The one constant during all of this was that biological systems were always the workhorse in removing unwanted chemicals from any environment.Fast forward to 2020 and I find myself retired and the world facing its next environmental crisis – Global Warming. The strange thing is that I could not find anyone that is applying biological methods to help solve this problem. So, I came out of retirement to see if biological systems could help. It turns out that is not that hard or expensive (<$50/ton) to capture and sequester CO2 using plants. Our first technology has just been awarded a patent and we have formed a company, “Carbon Captured Naturally” to bring this technology to the field.
