Napcor issued a statement refuting the PLA recycling experiment

with regard to the PLA sorting experiment of primo company intended to prove that PLA can be sorted out of the pet stream some time ago, the national PET container Resources Association (napcor) of the United States recently issued a statement on this matter, in which it questioned the intention of this conclusion. The main reason for napcor is the increase of sorting costs and pollution, as well as the loss of pet finished products. In addition, it is believed that the mixing of PLA will affect the quality of pet and have an adverse impact on the processing process

The chairman of napcor said: "We don't doubt that PLA can be recycled, but now there are obviously some key problems that need to be solved. The current situation is that PLA increases the cost and logistics burden of the recycling system, affecting the business of recycling companies, and if it continues to develop without control, the survival of recycling companies will also become a problem. Napcor has spent 20 years to help establish a successful domestic PET recycling facility system. At present, this kind of mixture The status not only endangers the PET recycling system, but also is not the solution to the recycling of PLA

Mikeschedler, technical director of napcor, said: "The whole premise of the experiment is: simply add the PLA container into the PET recycling stream, successfully sort it out, and finally find a market that can accept this material. This is like advocating that ceramics can be put into the glass material stream, because they can be sorted out, and eventually these mixtures will be purchased when there is a large amount. In fact, this is no different, and it is an unacceptable solution. Schedl ----- far east technology Associate professor xupiming Er of the university continued to point out that in addition to pet, PLA can be added to other polyesters, including PVC, PS and other resins. This practice only adds several more materials to the market

schedler added that since PLA and pet are not easily distinguished visually, an automatic sorting technology must be used. Some time ago, the sorting experiment of the PLA bottles of NatureWorks used by primo water company proved that the near infrared (NIR) sorting system is very effective in this regard, and 93% of the PLA materials can be sorted out of the pet material flow. Unfortunately, at present, NIR system is not used by all recyclers, because buying NIR system requires a considerable investment, usually more than 200000 US dollars. The recyclers who invest so much money in this kind of equipment hope that the sorting rate of the equipment can reach 95% or above. Other sorting equipment are not within the scope of the recent test. Also not within the scope of the test are the problems of PLA polluting products and PLA will get stuck in the desiccant

sabourin, executive director of nap revealed COR, said: "After so many efforts, the ratio of PLA that can be sorted out is still relatively low, and it is far from reaching the critical value for commercial operation. The reality is that PLA increases the loss of PET raw materials, and the lack of raw materials has become a major crisis in the PET recycling industry. A part of pet that could be recycled and entered the market has been sorted out with PLA. In recent years, it is not only the increase of sorting costs and the loss of production If there is no suitable way to collect and use the sorted products, or there is no market for these products, then we can only go to the landfill

bourin also pointed out that there are thousands of recycling bin projects on the roadside, which depend on the price of recycled materials to varying degrees. At this stage, napcor's goal is to help and support the establishment of these recycling bin projects, but PLA has weakened the price of recycled materials, and its response to PCU is smaller than UHMWPE. In the current economic situation, just maintaining these recycling bins has been a headache for many institutions. Napcor does not want to hinder the recycling of other resin products, including PLA, but napcor will never support things at the cost of damaging the existing successful operation mode

napcor hopes to attract more attention: at present, the domestic PET recycling system cannot successfully digest PLA containers, and the measures currently taken are not a model for the sustainable development of PLA. Napcor calls on brands and packaging decision makers to carefully consider the current situation and its impact on the product environment on the premise of meeting their packaging requirements before making a decision
