In the era of online shopping, packaging has become a large portion of waste in our daily world. Packages arriving in our mailboxes and on our doorsteps show up in many forms and most are not recyclable. Some of these items can be saved to re-use for future shipping needs. Here are a few of the common types:

Cardboard box - this is recyclable
Plastic envelopes - landfill (Amazon's plastic, bubble wrap lined envelopes can be dropped off at retailers that collect plastic bags)
Bubble lined envelopes - landfill

Packaging Fillers:

Packaging Peanuts, Air Pillows and Bubble Wrap are accepted for reuse at many shipping companies.
Paper - Recycle

Insulated polystyrene shipping containers are not recyclable, but can be reused for camping or picnics.
