David Denis grew up in a small village in Tanzania, where he was given a small piece of land to farm and discovered a passion for agriculture. After qualifying for a full scholarship to attend school, he studied chemistry, physics and biology. His education paired with his curiosity led him to start Cutoff Recycle, a company that reuses human hair to produce fertilizers, pesticides and concrete. Although his family and community viewed the use of human hair as a form of witchcraft, David persisted and found success, placing second in the 2021 GSEA Global Finals. David speaks about the importance of taking advantage of opportunities, giving back to your community and inspiring younger people to make the most of their abundance of tomorrows.
