High hopes for ‘green charcoal’

The ‘green charcoal’ is made from discarded plant waste such as millet and sesame stalks or palm fronds.

As they zigzagged from one machine to another in the searing African sun, the workers were covered in black soot.

But the charcoal they were making is known as “green”, and backers hope it can save impoverished Chad from ­rampant deforestation.
