A typical New Zealander throws away dozens of pens a year, but all brands of pens and markers are 100 per cent recyclable through a TerraCycle partnership with pen manufacturer BIC.
The recycling giant sorts, shreds and melts writing instruments into plastic pellets to be used in other products such as garden beds, park benches and playgrounds.
First Years Learning Centre has been collecting writing instruments for almost a year.
The idea is to keep your worn-out pens and, when you have a small container full, put them in the special letterbox at 38 Smithfield Rd, Gonville.
"The children will be excited to see these being kept out of landfill," says owner manager Katrina Culhane.
