The concept of circular economy has been ubiquitous over the past five years and steadily gaining a consensus as new paradigm. Circular covers wide spectrum topics ranging from waste management, through materials to supply chain, amongst which packaging is an essential part for achieving truly economy. It emphasised that resources should be kept in closed loops, thereby generating zero waste. However, largely due nature designated usage, industry built on linear model where designed, produced, consumed disposed of. This creates substantial amount waste, now growing concern earth ecosystem. To enable smooth transition system, design recognised fundamental stepping-stone towards In this study, extensive literature review performed, investigating body research relation paper reviews state-of-the-art design, including rules, guidelines, considerations tools can applied process A framework then proposed, summarising findings showing (i) factors determine material selection, (ii) strategies, guidelines taken into account conceptual development phases, (iii) indicators assist validation assessment circularity.

According to the European circular economy strategy, all plastic packaging placed on market by 2030 has be recyclable. However, for recycled plastics in direct contact with food, there are still major safety concerns because (non-)intentionally added substances can potentially migrate from polymers into foodstuffs. Therefore, Food Safety Authority (EFSA) derived very low migration limits (e.g., 0.1 µg/L polyethylene terephthalate (PET) and 0.06 high-density (HDPE)) polymers. Thus, use of recyclates post-consumer waste materials food is currently only possible PET. A first step assessing potential health hazards is, therefore, identification toxicological classification detected substances. Within this study, samples different packaging-relevant recycling (HDPE, LDPE, PE, PP, PET, PS) were analyzed. The identified examined a focus their abundance, toxicity (Cramer classification), polarity (log P values), chemical diversity, origin (post-consumer vs. virgin base polymer substances). It was demonstrated that polyolefins contain more classified as toxic than due higher diffusivity. In addition, despite its diffusivity compared polyolefins, high number found PS.

Low-density polyethylene (LDPE), extensively employed in flexible plastic packaging, often undergoes printing with inks. However, during the mechanical recycling of post-consumer waste, these inks act as contaminants, subsequently compromising quality and usability recycled material. To understand better exactly which ink components cause effects, this study comprehensively assesses thermal behavior three organic pigments two commonly utilised binders, correlated impact on LDPE-based packaging. In regard, focuses four pivotal factors: processability, properties, aesthetic attributes, volatile compound profiles. The results indicate that nitrocellulose, used a binder, degrades reprocessing, resulting film discoloration emission potentially odorous compounds. Conversely, are found to be dispersed within droplets polyurethane binder LDPE recyclates, whilst reprocessing printed samples detrimentally affects notably dart drop resistance, strain at break, number inclusions.

Abstract Since 1950, only 9% of all plastic produced has undergone recycling, and a mere 10% that been recycled multiple times. Most discarded (around 73%) ends up in landfills or is improperly managed, resulting widespread littering. The main reason for low recycling rates the lack technology multi‐polymer multi‐layer materials unsortable mixed waste. This waste one most accumulating types, including example single‐use food packaging with an average lifetime less than 6 months. These films, consisting various polymer are not feasible traditional mechanical which requires well‐sorted, clean, homogeneous materials.
