Paper, Plastic, & Metal

Welcome to the PRC Recycling Guide, where you can learn about recycling best practices.

All recycling is based on simple market economic principles. As commodities, things like aluminum cans are recyclable because industry recognizes their inherent value. In other words, an item is only recyclable if someone finds a use for the material. These markets exist for many of our household waste materials. Recycling works when the value of the particular material supports the collection, processing and re-manufacture of a product into a new one.

Act 101

Pennsylvania’s recycling law, Act 101, established a variety of rules ensuring Pennsylvanians have free and convenient access to recycling services for commonly recycled materials from their homes and at their places of business. While Act 101 does not guarantee residents access to recycling for all common materials, market conditions have supported the collection for most.

Please note that this information is based on PRC’s extensive technical expertise in the recycling industry and is not based solely on City of Pittsburgh policy and recycling guidelines. Official City of Pittsburgh Policy on plastic recycling remains that plastic bottles, jars, and jugs (#1 & #2) can be placed in curbside recycling. Find more information, see below.

Best Practices

  • Place CLEAN and DRY materials un-bagged into a blue recycling bin.
  • Set materials on the curb, separate from your trash, between 6 pm the day before collection and 6 am the morning of collection.
  • Protect your recycling and trash haulers, and NEVER put broken glass or other sharps in recycling. Instead, wrap the sharp object in softer trash.
  • If you keep your bin outside, keep the lid on until it’s time for your hauler to pick it up. The lid protects your recyclables from both the weather and curious vermin. The recycling haulers work very quickly, and your lid may go flying and or be misplaced.
  • When in doubt, ask PRC.

Most Recyclable Materials

PRC constantly analyzes policies and markets to ensure that we understand the best practices regarding recycling, so we are able to support the most vibrant and responsible waste diversion system possible in Pennsylvania.

Materials Recovery Facilities (MRFs) separate materials into bales of recyclable commodities (like cardboard, paper, aluminum, etc.). These bales are then sold to buyers who eventually re-manufacture or recycle these commodities into new products or materials. Recently, domestic and international buyers of these commodities have demanded higher quality material and are allowing ever lower contamination levels. With this refocus on quality standards, MRFs are having a difficult time finding economically viable markets to consume the materials. To overcome this challenge, MRFs are beginning to focus on a core group of consistently recyclable and marketable materials.

This update in the recycling market is what guides PRC’s communication at Recycling Bin Distribution Events and beyond. In fact, it is this very approach which has led to the bin distribution program itself; an effort to improve the quality of Pittsburgh’s recycling by removing the plastic bags from the system. It is also important to note that the challenge is not just in the marketability of a particular material but may also include that materials impact on the quality of what are otherwise highly valuable materials.

PRC therefore asks residents to focus on recycling the materials which are supported by clear market demand. We know that Pittsburgh residents, especially those like yourself who self-select to receive a recycling bin, are committed to recycling. To honor that commitment, we want to give you the most current information for which materials are in demand now and are expected to be into the future. We further desire to help you increase the volume of materials not only being collected for recycling but being processed and sold in environmentally responsible end markets.
