“…The effect of UV exposure was evident in terms of the difference of the total change in colour (Δ ) with respect to exposure time. However, no clear trend was observed in the colour parameter measurements with respect to exposure time, indicating that the condensation mechanism in the weathering chamber is a main factor that controls the change in colour, as noted in some previous works [39]. In addition, it was observed that photo-bleaching and a change in surface chemistry were a function of waste content in the formulation, leading to more discolouration (Δ ) with higher waste content.…”

“…The results of the samples produced under a DHT equal to 175 ∘ C did not show a clear trend between the amount of waste content and the value of the stress at break (MPa) (Figure 3(a)). Elzubair and Miguez Suarez [39] showed that waste content does not affect the stress values even in the presence of additives and fillers in recycled HDPE. This could be attributed to the crystallinity of the polymers constituting each blend at room temperature and the change in their amorphous region due to processing conditions, especially when considering the number of polymers each blend possesses [5,40,41].…”

Accelerated weathering test was performed on blends of linear low density polyethylene (LLDPE) and plastic film waste constituting the following percentages of polyolefin polymers (wt.%): LLDPE (46%), low density polyethylene (LDPE, 51%), high density polyethylene (HDPE, 1%), and polypropylene (PP, 2%). Compounded blends were evaluated for their mechanical and physical (optical) properties. The impact of photodegradation on the formulated blends was studied, and loss of mechanical integrity was apparent with respect to both the exposure duration to weathering and waste content. The effect of processing conditions, namely, the die head temperature (DHT) of the blown-film assembly used, was investigated in this work. It was witnessed that surpassing the melting point of the blends constituting polymers did not always result in a synergistic behaviour between polymers. This was suspected to be due to the loss of amorphous region that polyolefin polymers get subjected to with UV exposure under weathering conditions and the effect of the plastic waste constituents. The total change in colour (ΔE) did not change with respect to DHT or waste content due to rapid change degradation on the material’s surface. Haze (%) and light transmission (%) decreased with the increase in waste content which was attributed to lack of miscibility between constituting polymers.

“…Reutilizing the post-consumed polymeric materials reduces the environmental impact and the consumption of virgin plastics [19]. Regarding the reuse of polyethylene, considerably research has been conducted in the area of the polyethylene-lignocellulosic composites materials [12,[19][20][21][22][23][24].…”

The aim of this chapter is to describe in detail the advances in polyethylene reinforced with lignocellulosic material. Indeed, the successful employment of natural based materials to reinforce/improve the properties of polyolefins has been growing in a wide range of applications. Firstly, basic concepts and terminology adopted in the lignocellulosic composite materials are reviewed. The objective is to bring the reader's attention to important issues that must to be taken into account when working in this subject as well as by providing the most appropriate references for those with interest to delve into the topic. In the context of polyethylenelignocellulosic composites, ongoing research is then summarised mainly focussing on (i) the main aspects related to the selection of the commonly used lignocellulosic materials and the potential of its main chemical constituents, (ii) the principal methods used for the improvement of interfacial adhesion and (iii) the main adopted processing routes and the composite properties. Finally, applications, new challenges and opportunities of these polyethylene-lignocellulosic composites are also discussed.
