One of the most used resins in the plastics industry is polyethylene (PE).Although PE has good impact resistance and ductility, its low maximum use temperature and mechanical strength limit some commercial development, especially for load-bearing applications. To get better overall performances, crosslinking is performed to improve the chemical, mechanical, and thermal properties of PE. Although PE can be crosslinked by using various chemical and physical methods, this makes the resulting polymers more difficult to recycle since a three-dimensional (3D) network is created. In this review, we first describe the different crosslinking techniques for PE to manufacture crosslinked PE (XLPE) parts. Then, as more than half of the XLPE-based products are disposed directly after use, we present several options to reuse and recycle these products to overcome this environmental issue and find a sustainable solution. A focus is made on mechanical recycling and de-crosslinking techniques for XLPE to generate recycled-XLPE (r-XLPE). Finally, a conclusion is presented on the current situation and research gaps that must be filled by future works.

Rotational moulding is a plastic manufacturing technique primarily used to create hollow items without stress. In the current work, the banana fibre in powder form is combined with linear low-density polyethylene (LLDPE) at concentrations ranging from 5% to 40% by weight. Several tests, including Fourier transform infrared spectroscopy (FTIR), melt flow index (MFI), water absorption, and differential scanning calorimetry, were carried out for three samples for each percentage and the average of those samples has been considered to support the requirements of processability for rotational moulding. The significance of LLDPE and banana fibre peaks can be seen in the 5–30 wt. % range, according to FTIR. The MFI test followed by FTIR results conferred a flow-ability ranging between 3.022 and 3.5 g/10 min for 5 to 15 wt.% which is considered to be appropriate. A water absorption test was conducted from 5 to 15 wt.% for the blend, it is observed as fibre content increases water absorption increases. Based on the analysis 15 wt. % sample has been discarded noting a high absorption rate of 7 wt. %. From the thermal analysis, the crystallisation temperature of 5% and 10% LLDPE/banana blend was found to be 110.20°C and 111.08°C, making it suitable for rotomouldability. From the testing results, it can be inferred that a banana fibre concentration of 10 wt. % or less in LLDPE is the optimal range for producing a blend with better processability for rotational moulding.
