Recycling 101

In January 2019, we learned that over 50% of Philadelphia’s recycling was being sent straight to an incinerator in Chester. (Philadelphia incinerated its recycling for about six months, stopping in Spring 2019.) The problem was part of a larger issue with recycling nationwide — that the market for purchasing recycled goods, with China being the primary buyer, had shifted greatly.

In 2018, China decided to no longer accept recycled materials that didn’t meet new stringent rules around contamination and mixed materials. Soon, recycling, which had actually been profitable for Philadelphia, became an expense for the city.

One of the main reasons that much of Philadelphia’s and the United States’ recycling is so expensive to sell is that it is deeply contaminated. You can help address this problem by knowing what you can recycle and how best to clean your recycling.

How clean should it be?

What does it mean to have clean recycling? Your can of tomatoes, jar of jam or bottle of milk need to be rinsed of visible residue before you put them into the curbside recycle bin. Cardboard boxes (flattened, with stickers and labels included) are almost always ok, unless debris and grease have soaked into the fibers. Pizza boxes, for example, are often greasy, but if the top of the box is clean you can tear it off and recycle it curbside, discarding only the soiled portions.

You can recycle glass bottles, but do not include broken glass, window glass, light bulbs (recyclable at some home improvement stores) and porcelain in your curbside recycling. Don’t even consider adding in napkins, paper towels, used paper plates, waxed coffee cups, tissues or straws — they are as off limits as the Styrofoam containers and packing peanuts that often come in shipped materials. Plastic bags, including those air filled packs that often come in shipping boxes, cannot be recycled curbside, but many grocery stores accept them along with regular grocery store plastic bags if they are clean and dry.

What can you recycle curbside?

  • Glass jars and bottles
  • Paper (non-metallic)
  • Newspaper
  • Cartons (milk, juice, broth, wine)
  • Flattened cardboard (try to keep it dry!)
  • Books and magazines
  • Egg cartons (cardboard cartons, styrofoam should be put in the trash)
  • Plastic containers (rinsed, lids and caps ok)
  • Aluminum cans
  • Metal tins
  • Steel cans and lids
  • Empty paint cans

How can you reduce the amount of recycling or waste you create?

Reduce: You know the phrase reduce, reuse, recycle. It’s especially important to remember the first part of it. In a world where almost any item is available to be delivered right to your home or office via the click of a button, being aware of the environmental impact of having that item shipped to you is of utmost importance. If you suspect something will come in unrecyclable plastic or with excess packing material, consider if you really need that item or if you can purchase it in a more sustainable way.

Reuse used goods: When you need to purchase an item or you find yourself with more than you need, Philadelphia is full of consignment shops, thrift stores, used clothing boutiques, children’s sales and home goods and electronics resale shops that both accept used goods and offer gently used items at a fraction of the price of purchasing new. Facebook Marketplace, Craigslist and several apps and websites also provide places to buy and sell everything from leftover birthday party swag to shoes and baby gear. You can donate bedding, car seats, prom dresses and even used textiles (including very worn clothes) at a number of locations, listed on Green Philly’s website.

Buy Bulk: Many supermarkets (including Philadelphia branches of Mom’s OrganicWhole FoodsWegman’s and Weaver’s Way) allow you to buy items such as laundry detergent, rice, pasta, spices, nuts, beans and more in bulk with your own container. Make sure to note the weight of your container and subtract it from the full weight of your purchase.

Yard Waste and Composting

Yard Waste: Many municipalities, including the city of Philadelphia, have special pickups during the year (particularly in the fall) for yard waste. Instead of throwing your yard waste in the trash, it can be collected separately and used to create compost and mulch. Philadelphia’s sanitation centers accept Christmas trees, and many neighborhoods have private events that allow residents to bring their trees for nominal fees for reuse as compost or wood chips.

Composting: Food scraps and yard waste are close to 30% of what we throw away ( When thrown into an oxygen-deprived landfill, the very same items break down slowly and produce methane, contributing directly to global warming. Composting enables you to turn your organic waste — items such as fruit peels, food scraps, coffee grounds, leaves and more — into a resource that can help nourish your soil and spruce up your yard. You can compost at home or with the help of compost collection services in certain communities and markets, such as Mom’s Organic in Center City.

Recycling in the Philly Suburbs

Recycling requirements differ from county to county, and your municipality may have specific guidelines for your curbside trash and recycling. You can find out more about
your municipal requirements online or by calling your local administration building. You may also have access to county-wide recycling events for hazardous waste, electronics, shredded paper or other items that do not comply with municipal guidelines. Here are some links to county-specific resources to help you and your family start a conversation about recycling:

Recycling at the Academy

At the Academy of Natural Sciences, we believe that individual actions like recycling can truly make a difference. Each month of 2020, we’ll guide our community in a conversation about how everyday choices can affect the health of our environment. Follow along with us here, on our website, on social media @acadnatsci and #TakeActionANS, through email and in the museum to join the conversation. Plus, learn more about what we’re doing at the Academy in January 2020 to encourage recycling among our staff and visitors.
