“…The use of fillers and compatibilizers in the molded pulp material was recommended to advance the alternative upcycling and reusage of repulped LPB in molded pulp products. As the mechanical recycling of LPB provides a lower environmental impact in comparison to the incineration of its plastic fraction (Khan et al 2021), the manufacturing of molded pulp products from the repulped LPB can be exploited to reduce the environmental impact by reusing the plastic fraction of LPB instead of incinerating it.…”

“…Repulping reject consisting of plastics, aluminum, and some fibers is incinerated. Mechanical or chemical recycling of the repulping reject is an alternative to incineration, and the alternative treatment of LPB waste can be used to lower environmental impacts from handling of the reject (Khan et al 2021). In addition to the recycling method, the environmental impact of recycling LPB is influenced by composition of the recycled LPB (Sun et al 2021).…”

Laboratory sheets were prepared from repulped liquid packaging board (LPB) for press-forming experiments and tensile tests to study convertibility and mechanical properties of molded pulp material developed from the repulped LPB. Maximum forming depth was utilized as a convertibility indicator, and defect formation in press-formed molded pulp samples was observed with a visual analysis. Female mold temperature and pressing force were altered among press-forming parameters. The results showed that the laboratory sheets had a limited convertibility. The fragile structure of the laboratory sheets was connected to negative effects from the presence of plastic particles in the material. Increased heat input and decreased pressing force improved the convertibility, and the defect formation during the press-forming was aggravated by flattening of the material in flange and bottom regions of the samples. The use of repulped LPB as the raw material in the manufacturing of molded pulp by press-forming was found viable, and the presented solution offers an ecological alternative to conventional recycling of LPB.

“…Numerous studies have been recently conducted to highlight the issues related to the production of plastics from non-renewable and poorly biodegradable sources [ 210 , 211 , 212 ]. These issues should be understood and exploited with a view towards a greener recycling process for petroleum-based materials, with the hope of eventually replacing them entirely.…”

Recently, academic research and industries have gained awareness about the economic, environmental, and social impacts of conventional plastic packaging and its disposal. This consciousness has oriented efforts towards more sustainable materials such as biopolymers, paving the way for the “green era” of food packaging. This review provides a schematic overview about polymers and blends of them, which are emerging as promising alternatives to conventional plastics. Focus was dedicated to biopolymers from renewable sources and their applications to produce sustainable, active packaging with antimicrobial and antioxidant properties. In particular, the incorporation of plant extracts, food-waste derivatives, and nano-sized materials to produce bio-based active packaging with enhanced technical performances was investigated. According to recent studies, bio-based active packaging enriched with natural-based compounds has the potential to replace petroleum-derived materials. Based on molecular composition, the natural compounds can diversely interact with the native structure of the packaging materials, modulating their barriers, optical and mechanical performances, and conferring them antioxidant and antimicrobial properties. Overall, the recent academic findings could lead to a breakthrough in the field of food packaging, opening the gates to a new generation of packaging solutions which will be sustainable, customised, and green.

“…Er is één overzichtsartikel en dat besteedt nauwelijks woorden aan de verpulping, maar vooral aan verwerkingsmogelijkheden voor het drijvende bijproduct (ook wel PolyAl genoemd) (Robertson, 2021). Er is een levenscyclusanalyse over de verwerkingsopties voor dit bijproduct (Khan et al, 2021). De openbare wetenschappelijke literatuur besteedt nauwelijks aandacht aan de vervuiling van drankenkartonafval.…”
