Mechanical sorting is widely applied in the current Dutch waste management scheme, which sorts all of the polyolefin flexible packaging (different types of polyethylene, polypropylene) into the same stream, i.e. DKR 310, with different composition of each batch. Such inconsistency of feedstock composition brings remarkable hurdle to recycle this waste stream particularly on the sealing process design of the circular packaging from the stream. Therefore, Brightlands Materials Center is developing a prediction scheme for sealing performance of flexible packaging with recycled content based on the composition of the waste.
The realization of such prediction method is based on a machine learning assisted material model to tackle the complex polymer interaction of the mixed content and impurities. Therefore, this method could be readily extended in future cases with changes to waste stream composition from improved sorting and increased amount of packaging with mono material design.
A presentation by Yibo Su, research at Brightlands Materials Center.
Yibo states that as a research scientist working in the field of circular plastics, me and my colleagues are always striving to realize circular plastic packaging with minimum carbon foot print and maximized economical benefit. Therefore our research program is focusing on a better circular plastic pacakging design under the current Dutch waste management scheme, and we are targeting on improving the quality of circular plastic packsging by better understanding the sorted waste stream and to offer a suitable solution in a fast response by means of our machine learning assisted design tool.
