when it can be made into building material
New Zealand is throwing millions of dollars worth of recyclable polypropylene plastic into landfill, while at the same time importing recycled polypropylene, according to a study from Plastics NZ.
Polypropylene plastic is a durable, lightweight plastic that is used to make everything from ice cream containers to car bumpers. But its greatest asset is that it can be melted down and reused.
However, instead of being recycled, more than 67% of polypropylene goes to landfill after a single use.
