About us
We are the team behind
Green Carbon Technologies Sweden
—Lukong and Sara.
Both of us have engineering backgrounds, and our paths first crossed many years ago at Halmstad University.
With Lukong’s deep expertise, experience, and ideas around biochar, and Sara’s knowledge of 3D technology and design, we began a collaboration that continues today—
with Lukong working on the ground in Africa and Sara based in Sweden.
Our Vision
A future where waste becomes wealthy,
soils become stronger,
and every bag of biochar helps the earth breathe again
