Is it a PET bottle?
Reverse vending machines are the best way to ensure plastic PET bottles are recycled
While Singapore's plastic recycling rates are low (this is not unique to Singapore and is a global issue) this PET plastic is one of the better ones to put in the blue bins. Make sure it is rinsed!
Be weary of putting plastic in the segregated bin system which splits materials by paper, metal, plastic&glass.
Because plastic and glass have virtually no value, sometimes the "plastic&glass" bin simply gets dumped into the green trash bin. This does NOT happen with blue bins... but even in blue bins, plastic recycling rates are extremely low. If you really want to maximise the chance of these bottles getting recycled, find a reverse vending machine.
Does the bottle have any food waste like oil or sauce? Do not recycle it. Throw it directly into the trash.
Likewise if the plastic is NOT a bottle, the chance of it being recycled is low. Don't go out of your way to try recycle it.
Plastic #1, also known as polyethylene terephthalate (PET), is a type of plastic commonly used in the production of beverage containers such as water bottles, soda bottles, and juice containers.
Quite often, when a plastic is rigid and see-through, it is PET. PET is sometimes opaque and coloured, but this is less common..
While most types of plastic are not actually recycled, PET bottles often are. It is worthwhile trying to recycle clear PET plastic bottles.
