We know our customers are concerned about care of the environment, and so are we. We carefully considered different materials for our bags and settled on the #4 LDPE bag. We want our customers to have the best possible experience using our products, and this type of bag is durable and protects from weather damages during delivery.We also chose this bag because LDPE #4 plastic bags are 100% recyclable. There are numerous recycling facilities nationwide that take our bags. You can recycle our bags anywhere that takes grocery bags for recycling. Location can be looked up online here: https://www.plasticfilmrecycling.org/recycling-bags-and-wraps/find-drop-off-location/We are constantly working on innovations to reduce our environmental impact this even further. Currently, we are working with a plastic neutral NGO and formulating a way to add a bio-based polymer into our production line so stay tuned for more on that very soon!Every Catalyst Pet purchase online is now certified Plastic Neutral. By partnering with rePurpose Global, Catalyst Pet is donating a percentage of every product purchase to collect and reuse one ocean-bound plastic pouch for every one it sells online. By funding cutting-edge recycling technologies and supporting ethical wages for marginalized waste workers in India, the company is enabling rePurpose Global to tackle harmful plastic waste streams otherwise destined for landfills and waterways worldwide. By taking this bold commitment, every Catalyst Pet purchase online will now carry a net zero plastic footprint.
