What is PCR, PIR or bio resin?

  • Post-Consumer Resin (PCR) is a plastic that has been re-processed to be re-used in new manufacturing, and consist of blend or recycled resins that would have otherwise become urban waste. As the name suggest, it the material that has been reclaimed after it has left the hands of the consumer.
  • Post Industrial Resin (PIR) is plastic waste recovered from industrial processes, and consists of blend or recycled resins coming from industrial waste. In contrast to PCR, PIR is recycled plastic that never left the manufacturing floor (and therefore never made it to the consumer).
  • Bio-based material is a resin that derives some or all of its constituent monomers from biological sources. It is made from organic feedstock, carbohydrate-rich plants such as corn or sugar cane.

Why the need?

  • Post-Consumer Resin (PCR):Virgin post-consumer resins such as LDPE resin and polyethylene are originally processed from fossil fuels and turned into plastics. When these PCR resins are reused and transformed into new products, new fossil fuels are not required, which has exponential environmental implications.
    According to data from the Environmental Protection Agency, recycled plastics account for far less environmental impact than their virgin counterparts. As a matter of fact, many studies suggest recycled plastics contain over 25% less green house/carbon gas emissions than virgin resins. The more PCR resins you include in your products, the higher impact you can make on saving the environment.
  • Post Industrial Resin (PIR):The use of post-industrial resin means less plastic waste sent to landfills. It not only decreases need for raw materials but it can also decrease the energy required to produce packaging materials
  • Bio-based material:It has properties similar to polypropylene (PP) and polyethylene (PET) and looks just like ordinary plastic. In theory, it breaks down in a matter of weeks and does so without leaching toxic chemicals back into the soil and water table. (But like most organic material, its decomposition yields methane gas, a greenhouse gas many times more potent than carbon dioxide. Instead, PLA-based bioplastics should be taken to a commercial composting facility where it can be broken down in a controlled environment by microbes)

How Aptar Beauty + home can help?

Aptar has launched a Sustainable Materials Task Force and developed a strategy that addresses customer, consumer and regulatory expectations for sustainable product offerings. The fundamental strategies are to create a reliable network of innovative sustainable material suppliers having technical and supply capabilities, and to create a robust process with our suppliers to validate Sustainable Materials, enrich our database and offer ready-to-use solutions for our business.

The first tangible outcome from our strong commitment to sustainable materials is the recent launch of Aptar’s tube top, snap top and disc top closures made of PCR resin. Approved by the Food and Drug Administration (FDA), this PCR Poly Propylene has been blended with virgin Poly Propylene resin (50/50).

Furthermore, among all tests that are being conducted on PCR, PIR and Bio-based materials, it is key to mention the recent qualification of the GS and GSA dispensers with actuator, closure and dip tube components made of bio-based material. The GS and GSA dispensers were the first dispensing system on the worldwide market to accomplish an LCA (Life cycle assessment) and to achieve an EPD (Environmental Product Declaration) and now, with the recent certification of bio-based material, it aims to strongly reduce their environmental impact.
