PROFILE: LANGKLOOF BRICKS
EASTERN CAPE TOP GREEN ORGANISATION AWARD WINNER 2012 Langkloof Bricks, the pioneers of Vertical Shaft Brick Kiln technology in South Africa, have invested and created one of the most energy efficient clay brick firing systems in the world. The VSBK reduces Green House Gas Emissions and coal usage by up to 50%. The first South African six shaft VSBK was constructed, commissioned and inaugurated in late 2011 at Langkloof Bricks.
The proven VSBK system of firing clay bricks now gives the South African brick industry an environmentally viable alternative to the original method of firing bricks in clamps. At Coetzee, the Executive Director of the Claybrick.org says, “The VSBK Project is a brilliant example of how local expertise can partner with international knowledge leaders to benefit an entire industry and country.
