The sisters, from Sasolburg in the Free State, cofounded Ramtsilo Manufacturing and Construction, South Africa’s first plastic bricks manufacturing factory.
Made from 30% recycled plastic and sand, it is one of South Africa’s alternative forms of building materials.
‘Our bricks use less water to manufacture and there’s less water needed during construction. They have higher compressive strength at a lesser cost, are less porous, and last longer than conventional bricks, which means no cracks on your wall for a longer period of time, thus ensuring structural integrity.
They are also fire-retardant and provide greater insulation and energy efficiency which means your home is cooler in summer and retains heat in winter’ says Kedibone, co-founder of Ramtsilo.
The factory works with more than 50 waste pickers in the Free State and on the East Rand, who supply some of the plastic. The remainder is collected from waste management companies and packaging corporations.
