Vitamins containers are usually made of HDPE plastic or Glass. Both can be recycled. But putting them in the Blue Bin is not always the best option.
When PET is bad…
Occasionally you may also find vitamins in dark #1 PET bottles. For instance the brand Optimum Nutrition uses this for many of its products.
While coloured PET is theoretically recyclable, it is virtually never recycled in practice because it is technically challenging to sort and process. It just costs too much to recycle it.
For such containers, we recommend that you find reuses for them or throw them in the trash. They will not be recycled if you put them in a recycling bin.
