Negative impact of BD plastics on PC-PET recycling
“Not Shown Compatible with Recycling” say Trade Groups

The Association of Postconsumer Plastic Recyclers (APR) and the National Association for Plastic Container Resources (NAPCOR) released a statement today to address the growing problems resulting from the introduction of “degradable additives” into the plastic packaging marketplace, and the negative impact these materials will likely have on postconsumer plastics recycling.

“The facts are very clear,” said David Cornell, the Technical Director from APR. “The degradable additive concept effectively renders the product using the additive non–recyclable. Many recycled plastics are used to make durable goods. Failure of these next-use products, such as carpets or piping, could range from distressing to tragic.” Steve Alexander, Executive Director of APR, noted that, “Post-consumer plastic feedstock is being used increasingly in products of higher value and possibly where human health and safety is a critical component of their performance. Degradable additives mixed in with recycled feedstock will potentially contaminate the final product. Advocates for the degradable additives approach should prove ‘no harm’ both for first recycled end-use applications and subsequent, “ he added.

According to Cornell, APR’s membership has devoted considerable time and energy to produce guidelines to determine if a material meets or exceeds standards for recyclability. “We have a program in place to determine whether a material interferes with current recycling technology,” he noted. “Typically, any additive that diminishes performance properties renders the material non-recyclable. Should degradation prone material be mixed with recyclable material, the sum of materials likely becomes contaminated to the point that none of the material is recyclable, leading to landfill disposal… which is exactly the wrong thing to do.”

Dennis Sabourin, Executive Director for NAPCOR, said, “It is important not only that the next use of a recycled bottle be unimpaired for its full service life, but that the next use material can itself be recycled. Strapping that contains plastic from used soft drink bottles is likely itself to be recycled into new strapping. This is key to the spirit and definition of sustainability, so it is important that any additive intended to degrade not impair the repeated use of the plastic molecules.”

APR and NAPCOR encourage companies seeking to use any additives to work with APR and plastics recyclers to ensure their material does not contaminate the material’s ability to be recycled.
