The new structures are made of HDPE (High Density Polyethylene). HDPE is a #2 plastic which is a commonly recycled plastic, making our new bottles more easily recyclable.
The new bottles also contain 50% PCR (Post-Consumer Recycled) plastic. In other words, PCR is made out of used plastic that would have otherwise ended up in landfills. This reduces our usage of “virgin” (new) plastics. Before 2021, the old bottles were made out of green colored PET (Polyethylene terephthalate). Green/colored PET is not as easily recyclable because there is a limited secondary market for colored PET plastics.
