don’t use plastic if you can avoid it. It’s not easy to recycle.
Plastic bags, styrofoam, and those hard plastics marked types 1 & 2 are the ones most likely to be recycled into new products. They are easy to break down and recycle into new containers.
Hard plastics marked types 3 through 7 are most likely to be filtered out and either incinerated or dumped straight into the landfill, as it costs more to recycle them than to just create new straight from oil.
