As well as a whole range of compact cameras and printers, Canon has launched two new green calculators.

The LS-120TSG and the F-502G are made from 100% recycled plastic from recycled Canon copiers.

Both models also feature replaceable batteries, auto-power off and the LS-120TSG uses solar-power.

The LS-120TSG will be available from June for £11 while the F-502G will be available from May priced at £8.
