In today’s episode, we meet Isaac Macharia, a Kenyan social entrepreneur with Marafiki Community International who makes cabins out of plastic to keep Kenya’s Masai Mara clean. In 2015, Macharia was on his usual tour-guiding routine at the Masai Mara in Kenya. It bothered him.

Also Meet a young Kenyan lady repurposing waste glass at Masai Mara.

He decided to construct cabins using not only plastic bottles, but also stashing and hiding every non-biodegradable waste you can think of—straws, broken glass bottles, clothes, beer cans, to name just a few—right in there during construction. To harden and convert the plastic bottle into a smaller brick, they add dry sand. The contractors used plastic to make the cabin roof. Contracted local women collect these bottles and fill them with sand or paper. Listen by clicking the link above or here.
