Landfills full of (climate) gold

The chance: Waste management strategies could inject an additional $8 billion annually into Africa's economy, fostering growth and jobs, says the UN. 

• Building successful waste-tech companies is aided by a lack of competition. The sector is overlooked by most mainstream operators.
