More than 1.1 billion inkjet cartridges are used around the world every year, and up to three pints of oil are used in the manufacture of each one. If you laid them end-to-end, they would be 129 times longer than the great wall of China.
Less than 30% of all these cartridges are being recycled. The plastic that is contained within the casing of a printer cartridge can take up to 1,000 years to decompose. In the UK alone we use 65 million printer cartridges and we only recycle 15% of them.
