“…Already relatively small amounts of foreign bodies in the polymer matrix can have severe effect on mechanical, rheological or aesthetical properties. Kühnel et al (Kühnel et al, 2019) showed that concentrations as low as 0.17 wt % of paper labels in PolyCarbonate/Acrylonirtile Butadiene Styrene (PC/ABS) can result in a loss of 96 % in strain at break, while comparable concentrations of PolyPropylene (PP) labels resulted in a significantly lower influence. Not only the type of impurity but also the size, shape and distribution in the polymer matrix will determine the final effect the impurity has on the quality of the recycled plastic (Adams, 1993;Eriksson et al, 1998;Perrin et al, 2016).…”

The quality of mechanically recycled plastics from WEEE is seen as one of the main bottlenecks for their re-application in high-quality products to enable a circular economy for these materials. Most literature focuses on the quality at the end of the value chain while significant potential to improve the performance of the entire value chain is seen by the quality assessment of input material of recyclers. In this research a testing procedure for mixed plastic flakes by Fourier-Transform InfraRed (FTIR) spectroscopy, X-Ray Fluorescence (XRF) and manual composition analysis assisted by computer vision. Mixed plastics from TV housings, washing machines, fridges and fridge drawers were taken as case studies. It is shown that unwanted plastic types, glass, metals, wood, rubber and foam as well as additives such as talc, calcium carbonate or brominated flame retardants can be detected by the procedure. In addition, a Failure Mode and Effect Analysis (FMEA) is shown to be a powerful tool for a risk-based assessment of the most relevant quality influences, which allows to define strategies for quality control. The economic evaluation showed that automation is required to allow the systematic use of the testing procedure.

“…ABS is an amorphous thermoplastic terpolymer possessing an excellent balance of properties, dimensional stability, chemical resistance, and non-toxic to human. Besides that, ABS is widely used as one of blending ingredient to improve mechanical properties especially impact toughness in the brittle polymer [4,5]. By selecting ABS as blending material for PLA, the resulting blend capable of retaining PLA strength and stiffness while remedying its weak impact properties.…”

Polylactic acid is a biodegradable polymer derived from renewable resources, showing potentials in replacing traditional petroleum-based polymers, yet its brittleness limits its applications. Thus, blending polylactic acid with acrylonitrile butadiene styrene as well as incorporation of fillers were used to enhance the mechanical and biodegradability properties of polylactic acid by extrusion compounding. The aims of this study to produce and investigate PLA/ABS blend incorporated with natural filler, NFH and IC to improve the properties pf PLA/ABS blends. Two types of fillers used were Nypa fruticans husk and isolated cellulose from Nypa fruticans husk which was obtained by using Soxhlet extraction. Transform Infrared spectroscopy analysis was used to characterize and verified the extracted substance was isolate cellulose. Tensile, impact and biodegradation test were conducted to investigate the mechanical and biodegradability properties. The optimum blend ratio for polylactic acid/acrylonitrile was 75/25 php base on previous studies, and it was found that the incorporation of both fillers, Nypa fruticans husk and isolated cellulose from Nypa fruticans husk had decreased the tensile strength, elongation at break and impact strength of the composite however increased the Young’s Modulus and biodegradation weight loss. Meanwhile, at similar filler content, the tensile strength, Young’s modulus and biodegradation weight loss of polylactic acid/acrylonitrile butadiene styrene blend incorporated with isolated cellulose were higher value compared to polylactic acid/acrylonitrile butadiene styrene blend incorporated Nypa fruticans husk. Furthermore, morphological studies showed a well-coated filler by matrix and reduction of filler pull out when isolated cellulose was incorporated in polylactic acid/acrylonitrile butadiene styrene blend. Therefore, it was found that the incorporation of isolated cellulose in polylactic acid/acrylonitrile butadiene styrene blend, shows higher mechanical and biodegradation properties than polylactic acid/acrylonitrile butadiene styrene blend incorporated with Nypa fruticans husk.
