First launched in the 1970s and now found around the world, recycling programmes help reduce the amount of waste that enters landfill and conserve natural resources. By now, we've all become accustomed to recycling cans, bottles, jars and newspaper. But these aren't the only items that can be recycled. Many products most of us simply throw away can also be reused.

When a printer's ink cartridge runs out, most people simply throw the cartridge, which has both plastic and metal components, in the bin.

Like shoes, well-beloved denim jeans are often kept until they are so worn and tattered that they can't be donated to a charity shop. Nonetheless, the fibres in these items can still be recycled by specialist companies and made into items ranging from home insulation to sandals.
