“When invasive hyacinth blocked their canoe trips in the Khayelitsha wetland, Siyanda and Akhona Sopangisa started harvesting the hyacinth to make biochar.”

Biochar production process

They dry hyacinth in sun, burn in kiln, mix with cow dung, rest two weeks before packing.

“To produce 1kg of biochar, you need 5kg of hyacinth.”

Char2Cool training

Char2Cool, a german non-profit, taught brothers how to make biochar from hyacinth.

“While we were still learning, we sent them videos of the biochar we made via whatsapp”

Current sales

They sell biochar at R80 in suburbs and R20 in Khayelitsha, with seedlings selling better.

“We are out of seedlings now because they sell well.”

Gardening project

Volunteers launched Masilime Sonke Gardening Project with 46 home gardens and a ten-year lease.

“Since we don't work, the gardening project helps make money to buy electricity, meat and food.”

Future plans

Brothers aim to hire unemployed residents to produce biochar for big farmers.

“We will hire unemployed residents to produce the biochar.”
