Nalgene reusable polypropylene(PP) products are designed to last many years under typical laboratory conditions. Yet, as with all durable products, they need to be retired and replaced eventually. These racks and their packaging are recyclable in many communities. Please recycle the corrugate cartons and LDPE bags in which your Nalgene products are packaged. And at end of product life, please wash and recycle your Nalgene racks if services are available in your community.
