Welcome to the latest edition of eco@africa

This week's eco@africa show brings you a host of green ideas from Ghana to Zimbabwe that are helping the environment and our planet!

First, we're off to Kenya to check out a unique snake farm – while snake bites can be deadly, they are treatable if you know how to do it correctly. So this farm helps produce effective anti-venom while also teaching the public the important role snakes play in maintaining biodiversity.

Next, we visit a town in France which has hit upon a special way to deal with its organic waste: giving every interested household chickens, which gobble up the leftovers, meaning a huge reduction in food waste.

We're then off to Zimbabwe, where a clever app is helping to cut traffic and food waste at the same time by letting people order fresh produce – meaning farmers only take exactly as much as they need to the market, reducing the amount of perishable unsold items that are thrown away afterwards.

In Ghana, we meet this week's eco hero: an entrepreneur who has introduced a technology that is turning organic waste into biogas, and helping reduce the rate of deforestation in the country in the process.

A miracle cotton wool takes us to Germany, where a firm has developed a special material that can soak up any kind of oil – even potentially crude oil spills.

Finally we visit South Africa, where invasive trees species are being cut down to protect native vegetation – with the wood turned into furniture for poorly-equipped schools.
