Dozens of mobile phones have already been donated to Bristol Zoo Gardens
If you got a new mobile phone for Christmas, then Bristol Zoo Gardens wants to hear from you.
They are appealing for people to recycle their old phones to help "safeguard the future of gorillas in the wild".
Mobile phones contain coltan, a mineral extracted from the home of the critically endangered lowland gorillas.
The zoo will receive £1.75 for each mobile donated, which will go towards its conservation projects.
Mining for coltan takes place on a large scale in the forests of the Congo Basin in central Africa.
It has led to widespread deforestation, which, in turn reduces the available habitat for animals.
Opening up the forests has also resulted in an increase in illegal poaching and the bushmeat trade.
Bristol Zoo is asking people to help reduce the need for coltan by recycling their old phones and help protect the future of gorillas which live in the forests of the Congo.
'Do your bit'
Bryan Carroll from Bristol Zoo said: "We are asking them [people] to consider recycling their old phones for this very valuable and worthwhile cause.
"You'll also be doing your bit to help the environment by saving waste from going to landfill.
"Even if your phone can't be re-used, it will be recycled."
Unwanted mobile phones (with the SIM card removed) can be dropped off at the zoo or posted, in a sturdy envelope, with the phone battery, to:
• Bristol Zoo Mobile Phone Recycling, Greener Solutions, FREEPOST, LON17592, Mitcham, CR4 3UZ.
Alternatively, you can request a freepost envelope by contacting Lizy Jones on 0117 974 7329 or email
