Recycling Plastic Packaging: What Plastics Are Acceptable?

what plastic packaging is recyclable

Plastic packaging waste is a significant contributor to the millions of tons of plastic waste generated annually, with the average American generating over 250 pounds of plastic waste per year. While recycling plastic packaging is complex due to the variety of plastic types and local recycling capabilities, it is possible to recycle certain plastic packaging. The recyclability of plastic packaging depends on factors such as the type of plastic resin, local recycling infrastructure, and the availability of specialized recycling programs. Understanding these factors is crucial for individuals aiming to recycle plastic packaging effectively and contribute to a more sustainable future.

Plastic bags and wraps

The recyclability of plastic bags and wraps depends on their resin identification code, which is typically found on the product's label and indicated by a recycling symbol with a number inside. The most commonly recyclable plastic bags and wraps are made from polyethylene terephthalate (PET or PETE, resin code 1) or high-density polyethylene (HDPE, resin code 2). These bags and wraps are widely accepted in recycling programs and can be recycled into new products, such as fleece jackets, car parts, and even new bags. However, it is important to ensure that the bags and wraps are clean and dry before placing them in the recycling bin, as contamination can render them unrecyclable.

In addition to PET and HDPE, some communities may accept plastic bags and wraps made from low-density polyethylene (LDPE, resin code 4) and polypropylene (PP, resin code 5). LDPE plastic bags include produce bags, dry cleaning bags, and the outer packaging of products such as toilet paper. PP plastic wraps are often used for products like kitchen paper towels and biscuits or cookies. Before including these resin codes in your recycling, it is essential to check with your local recycling program, as acceptance may vary depending on the region.

It is important to note that not all plastic bags and wraps are recyclable. Those that are stretchy or crinkly, such as plastic wrap used for food storage or plastic shipping envelopes, often belong to the category of hard-to-recycle plastics. This includes plastics made from linear low-density polyethylene (LLDPE, resin code 4) and polyvinyl chloride (PVC, resin code 3), which are not widely accepted by recyclers due to their unique chemical structures. Additionally, any plastic bags or wraps that are soiled, greasy, or contaminated with food waste are not recyclable and should be disposed of in the regular trash.

Some examples of plastic bags and wraps that can be recycled include:

  • Grocery bags (HDPE or LDPE)
  • Retail bags (HDPE or LDPE)
  • Bread bags (HDPE or LDPE)
  • Dry cleaning bags (LDPE)
  • Toilet paper and paper towel wraps (LDPE or PP)
  • Plastic shipping envelopes (LDPE)
  • Produce bags (LDPE)
  • Ice bags (LDPE)

It's important to keep in mind that the recyclability of these items may vary depending on your location, so it's always a good idea to check with your local recycling guidelines. Properly sorting and preparing your plastic bags and wraps for recycling can make a significant difference in reducing waste and promoting sustainability.

Plastic lumber

While plastic lumber has certain advantages over wood, there are concerns about its recyclability. Some sources argue that turning plastic packaging into plastic lumber does not constitute recycling, as it does not reduce the need for new plastic production. This process, known as downcycling, extends the life of plastic but does not create a sustainable loop as the resulting product cannot be recycled further.

One example of this is Amazon's plastic packaging, which is often claimed to be recyclable. However, research has found that only a small fraction of Amazon's plastic packaging ends up at recycling centres, with the majority becoming pollution or waste. Some of this plastic packaging may be used to create plastic lumber, but it does not address the root issue of excessive single-use plastic production.

Despite these concerns, plastic lumber has several benefits. It is maintenance-free, resistant to moisture, chemicals, graffiti, and insects. It does not require the introduction of preservatives or paint for maintenance. Additionally, it is durable and long-lasting, making it a cost-effective alternative to wood in the long run.

Overall, while plastic lumber may not be the perfect solution to the plastic waste crisis, it can be a viable option for certain applications where its advantages over wood are beneficial. However, it is essential to recognise that reducing single-use plastic production and promoting proper recycling practices are crucial steps in addressing plastic pollution.

Plastic film packaging

Plastic film can be recycled and upcycled into many useful products. For example, recycled plastic film packaging can be used to make durable plastic or composite lumber for decks, fences, and other outdoor uses. One company, Trex, claims that a 500-square-foot composite deck contains about 140,000 recycled plastic bags. Plastic film can also be reprocessed into small pellets, which can be made into new bags, pallets, containers, crates, and pipes.

However, recycling plastic film packaging can be challenging. Most curbside recycling programs do not accept plastic film, so it must be taken to a drop-off location. In addition, plastic film can be difficult to recycle if it has been used for food packaging or is contaminated with food or liquids. It is important to ensure that any plastic film intended for recycling is clean and dry before drop-off.

There are ongoing efforts to improve the recyclability of plastic film packaging. For example, the Film & Flexibles Recycling Coalition works to identify and scale recovery methods for film and flexible packaging. New regulations and increased public commitment to sustainability are also driving a demand for more recyclable materials and greater recycling clarity.

Overall, while plastic film packaging can be recycled, it is important to research the correct way to do so in your local area and to ensure that the plastic is clean and dry before drop-off.

Polypropylene

It is important to note that not all recycling centers accept PP, and it is always worth checking with your local center before disposing of this plastic. However, there are many benefits to recycling polypropylene. As well as reducing the amount of plastic waste that ends up in landfills and the natural environment, recycling PP can also help reduce energy usage and the consumption of resources such as water and fossil fuels.

When recycling polypropylene, it is important to ensure that the plastic is clean and dry. Any food residue or liquid left in containers can contaminate the entire batch of recycling, making it unusable. It is also worth noting that not all PP products are created equal—some may be treated with chemicals or contain other materials that make them non-recyclable.

Recycling symbols

Other recycling symbols provide information on how to dispose of an item or whether it can be recycled. For example, the symbol of a crossed-out wheelie bin indicates that electrical products, batteries, and their packaging must be recycled through a recycling centre or retailer. The "Green Dot" symbol, used in some European countries, indicates that the producer has made a financial contribution towards the recovery and recycling of packaging but does not necessarily mean that the packaging is recyclable.

It is important to understand the recycling rules and legislation in your town or local area to ensure that you are properly following the guidance of recycling symbols.
