Plastic bottles come in all different shapes and colours, but Hamilton City Council urges Hamiltonians to 'keep it clear' when choosing a soft drink bottle.
Clear plastic bottles can be recycled up to nine times which puts less stress on our environment. Coloured plastic can be recycled, but the dyes adding the colour turn grey when processed.
Coloured plastic with the recycling number 2 generally comes from household cleaning or hygiene products or milk bottles. This plastic is mainly white and has a market to be recycled for wheelie bins and plant pots.
However, coloured plastic 1 (PET or food-grade plastic), in particular, soft drink and sports drink bottles, is harder to recycle and doesn't have a market.
