Use Post-Consumer Mechanically Recycled Content

Many companies have now committed to increase their use of post-consumer recycled (PCR) content in their packaging, to help drive the scale-up of high value mechanical recycling systems. PCR content comes from packaging that has been used by a consumer and then recycled, compared to post-industrial recycled content left over from industrial manufacturing processes that has never been sold to a consumer.

There is increasing demand for PCR from brands globally as both consumers and investors pressure companies to increase the circularity of their packaging. One example of a public commitment to utilize more PCR is the Ellen MacArthur Foundations’ Global Commitment. Companies that have signed up to the Global Commitment utilized an average 6.2% PCR in 2019, a 22% increase from 2018 (1). Analysis by The Recycling Partnership projects that demand for recycled PET could increase by 300% by 2025 (2).

The Plastic IQ tool focuses on PCR content because most plastic waste is post-consumer and demand for recycled content is needed to drive collection, sorting and recycling for this material. To be accepted for use in food applications, recycled plastic content has to meet a higher standard, sometimes creating a barrier. The table below shows how likely it is for different plastic types to be used as recycled content currently, split between food-grade and non-food-grade applications.

The US Plastics Pact recommends an average target of 30% recycled or bio-based content across a company’s portfolio of plastic packaging (3). This matches the targets of many of the companies involved in the Ellen MacArthur Foundation’s Global Commitment. Beverage companies have set many of the most aggressive targets, with Danone setting its target at 50% by 2025 and Coca-Cola at 50% by 2030. Cosmetics company L’Oreal has also set a goal of 50% by 2025 (1). Regulation is also increasing. For example, California requires all plastic beverage bottles covered by their container redemption program to contain 50% PCR content by 2030 (4).

For some packages, like PET bottles, it is possible to aim as high as 100% PCR. In fact, numerous beverage companies have already introduced 100% PCR PET bottles or announced a commitment to do so by 2025, including Coca-Cola, Nestle Waters, and Evian. Other companies, such as Organic Girl, utilize 100% rPET in their PET thermoform clamshells.

PCR is also available in HDPE and LDPE for use in packaging. Seventh Generation uses 100% PCR in multiple HDPE bottles for cleaning products. LDPE film, including overwrap and stretch wrap, is also available with high percentages of PCR. This can be used as a wrap either around a single product or around a bundle of individually packaged items.

Recycled resins are commodities, and their price fluctuates depending on numerous factors, including virgin resin prices, bale prices and demand, and availability of material. Recycled resin prices have generally tracked up and down with virgin resin prices, but comparisons can be difficult due to the different quality of the resin, different resin grades, and different colors. Several published reports claim varying levels of pricing of recycled content relative to virgin pricing and companies should work with their suppliers and partners to evaluate costs of using PCR. Companies should also consider investing in increasing collection to grow supply to lower pricing of PCR over the long term.

Using recycled content offsets the need to produce more virgin material, and is less energy-intensive than virgin material. Based on averages from multiple life-cycle analysis (LCA) studies, Plastic IQ analysis estimates that recycling and using PCR content from mechanical recycling lowers life-cycle GHG emissions by over 70% compared to virgin plastics made from fossil fuel sources.

Key Benefits

  • Driving the circular economy: Using mechanically recycled content is critical for creating a circular economy that keeps materials in use and not buried or burned. Companies making long-term commitments to buying PCR allow for recyclers and other companies along the value chain to invest in in-creasing the collection, processing, quality, and quantity of recycled material.
  • Satisfying consumer preference: Consumers often don’t fully understand how the recycling system works but recycled con-tent is cited as a positive sustainability related product attribute.
  • Reduced risk: Using PCR supports the expansion of the Circular Economy and may reduce the risk of poli-cy makers mandating recycled content.
  • Decoupling from fossil fuel volatility: Virgin plastic prices fluctuate significantly with changes to oil price. Companies that incor-porate recycled content may be able to decouple their procurement costs from that volatility.
  • Greenhouse gas reduction: Replacing virgin plastic with recycled content saves significant GHG emissions. Plastic IQ estimates that over 80% of CO2e emissions are saved per ton of recycled content used, com-pared to virgin plastics. Companies are encouraged to review published and peer-reviewed LCA information for recycled plastics.
  • Job creation: Recycling plastics creates more jobs than virgin plastic production. For example, Association of Plastic Recyclers (APR) estimates that its Demand Champions program created over 2,000 jobs along the supply chain by increasing demand for PCR (6).

How to make it work

  • Identify suitable packaging types: Certain packaging types, such as PET bottles, non-food HDPE or LDPE, and other packaging formats that are less sensitive to color variations or imperfections, are likely better suited to incorporate PCR. The table above shows the current plastic types that are most likely to easily accept recycled content.
  • Work with your suppliers: Packaging suppliers are already able to incorporate up to 100% PCR in many packages to-day. Identify long-term goals and collaborate on increasing PCR in existing packages – or change packaging designs to incorporate more material.
  • Encourage resiliency of PCR through long-term commitments: While long-term contracts are common with virgin resins and even with PCR content for paper, they have not yet been significantly leveraged for recycled plastic resins (5).
  • DEnsure that the resin is certified post-consumer material: There are numerous organizations that can help with the verification of PCR, including APR, which maintains a list of auditors that meet their certification (7).
  • Support efforts to boost collection: There are various organizations working on increasing the collection of recyclables. Companies who want to use more PCR should invest in growing collection through an industry collaboration.

Enabling system conditions

  • Increased, constant and predictable demand: Strong demand commitments and long-term offtake agreements are critical to enable recy-clers to invest in more and better processing capacity. It is therefore not sufficient to just use recycled content, but to create constant and predictable demand for it.
  • Increasing recycling rates will improve supply: Today, packaging companies must compete with other industries for a limited stock of re-cycled resins. Investment in improving collection programs for residents will increase avail-able supply of recycled content.
  • Invest in the system: Companies and organizations can work together to improve the recycling system by in-creasing access to curbside service, expanding the materials accepted, and improving the quality and capture of the material going into and out of materials recovery facilities (MRFs) and reprocessors.
