Kinloch Castle Friends Association (KCFA) has registered with recycle4charity to raise funds for the historic Isle of Rum castle.
The company offers £1 for every used printer cartridge sent to them and 50 per cent of the market value of old mobile phones.
Cartridges can be recycled by sending them to recycle4charity in a recycling bag and phones can be recycled through the use of recycling boxes. Bags and boxes can be obtained through the KCFA.
