Biodegradable phone!

A mobile phone implanted with a sunflower seed and made from biodegradable material is among the cutting edge cellular technology which has been unveiled at the Science Museum.

The theory is that the biodegradable phone cover will release nutrients as it deteriorates, helping the sunflower grow.
It is hoped that the prototype, developed by researchers from Warwick University, will mean phone covers can simply be buried in the ground after use.
The innovation was one of a series of biodegradable phones on display at the Dead Ringers? exhibition at the Science Museum.
The biodegradable NEC phone cover, which is currently only available in Japan, was shown for the first time in the UK.
Among the more unusual exhibits was a lasagne-based circuit board and a phone which will be able to take itself apart to aid recycling.
According to the exhibition, 1,712 mobile phones are upgraded every hour in the UK after 18 months of use, even though they are designed to last up to 10 years.
There are about 50 million mobiles in the country and the number of phones globally is expected to reach two billion by the end of the year.
Environment Minister Ben Bradshaw said: "We tend to upgrade our phones without thinking about what happens to our old one when we no longer need it.
"So what should we do with our old phones when we do?
"And what can manufacturers do to make it easier for people to make the right choices for the environment?
"These are some of the core questions we are raising in our current review of England's waste strategy so the Science Museum's exhibition is especially timely."
