The problem of plastic waste seems insurmountable. The good news is plastic recycling is on the rise and that is good for the circular economy. In parts 1, 2 and 3, we delved into the role of the waste management and recycling industry and how material sorting technologies can help. Part 4 is all about the increased use of recyclates as an essential part of properly closing the plastic cycle.
The plastics industry is facing a great many challenges. Harvesting recyclates from waste is only worthwhile if the plastic has been properly sorted and does not contain any metal, and if the products made from the secondary raw material are similar in quality to those made from new plastic.
Manufacturing recyclates from plastic waste is the first step. But in order to fully close the plastic cycle, more recyclates need to be used in the manufacturing of new products. This is a lucrative business for plastics processors, as recyclates are cheaper than new materials.
With material costs in the plastics industry accounting for 40% to 80% of total expense, depending on the segment, using recycled materials can significantly increase profitability. In addition, the secondary raw material in its ultra-pure state has practically the same characteristics as new plastic.
Yet there are still a number reservations in the industry when it comes to recyclates. The quality of the input material is particularly important in this regard. Recyclates must be free from any contamination to protect processes and machines from damage and ensure that the final products meet high standards of quality.
