PLA Plastic vs. PET Plastic

PET plastic is a petroleum-based plastic while PLA plastic is a bioplastic typically made from fermented plant starch. While PET plastic can be easily recycled, PLA is more difficult to recycle and requires a special facility in order to be composted. Before disposing, avoid contaminating your recycling by double-checking whether your item is PET or PLA and the current disposal instructions for that material.
