00:00These bricks save water and trap CO2. They are made from black wattle and eucalyptus,
00:05invasive species to South Africa that need huge amounts of water. The wood is shredded,
00:10mixed with low cement binders and pressed. The makers say the bricks are fireproof and
00:15better insulated than clay or concrete. And because trees trap carbon while growing,
00:20these bricks act like little CO2 storage units. Here's why that matters. The production of cement,
00:26the main ingredient in concrete, is responsible for almost 8% of global emissions. Building
00:32materials like these can help cut down emissions and restore ecosystems damaged by thirsty invasive trees.
