Styrofoam recycling drop-off may be a good choice if you have a lot and you combine it with another trip to that area. Avoid or minimize purchases that you know will be packed in Styrofoam. Reach out to the company that you received the Styrofoam from and ask them to use another material, or a convenient means of recycling it. Support extended producer responsibility. Choose products that contain post-consumer recycled plastic.
Due to the light-weight nature of Styrofoam, food waste makes up most of the weight (30%) in our landfills. While it may feel bad to throw large volumes of Styrofoam in the garbage, eating food too-good-to-waste and composting food scraps has a bigger environmental impact by decreasing GHG emissions of food in the landfill.
