“…Both, LDPE and HDPE, belong to the group of polyethylenes, however, their behavior during mechanical recycling differs significantly, and one cannot be predicted from another Thus they need to be studied individually. Findings on M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT extensively recycled LDPE have been already reported by our group [12], whereas here we summarize results on mechanical recycling of HDPE material.…”

“…Jin et al studied the degradation behavior of LDPE under one hundred consecutive extrusion cycles through a twin‐screw extruder. They reported that chain scission and crosslinking occurred simultaneously when reprocessing recycled LDPE.…”

“…Jin et al reported the crystallinity (based on ISO 11357 ) of recycled LDPE is relatively constant up to the 40th extrusion cycle, and then decreases between the 40th and 50th extrusions, and keeps unchanging until the 100th extrusion. The decrease in crystallinity is attributed to the creation of structural irregularities due to the increasing crosslinking.…”

Efficient technology and applications for recycled polymer waste has become increasingly important to decrease environmental contamination and to conserve nonrenewable fossil fuels. Mechanical recycling is the most widely practiced in Australia, since it is relatively easy and economic; and moreover, infrastructure for collection and reprocessing has been well established. In order to improve quality of end products of recycled plastics, various workable reprocessing techniques in the second stage of mechanical recycling have been developed and widely applied in the recycling industry. This article critically reviews the current reprocessing techniques of recycled polyolefins. Reprocessing recycled polyolefins is always accompanied with degradation, crystallization, and consequent processability problems, which result from molecular chain scission, branching, and crosslinking. The present state of knowledge and technology of various reprocessing techniques, including melt blending, filler reinforcement and mechanochemistry, is then described and evaluated systematically. Each reprocessing technique presents its own individual advantages and special applications. POLYM. ENG. SCI., 55:2899-2909, 2015

“…during lifespan and reprocessing. Jin et al who studied the influence of multiple extrusion on the flow properties of low-density polyethylene (LDPE) reported that MFI decreased from 2.31 g/10 min to 0.02 g/10 min after 100 extrusions [17]. This change was attributed to chain scission or crosslinking of the polymer chains.…”

The recyclability of polystyrene, acrylonitrile butadiene styrene, polystyrene and polyvinylchloride waste and using them as a source for 3D printing were studied. Filaments of about 3 mm in diameter were extruded successfully with a small-size extruder. The processed filaments were tested on a broad range of parameters - glass transition temperature, tensile properties and a pyrolysis scenario were obtained. The measured parameters were compared with parameters of virgin counterparts presented in the literature. In order to estimate the toxicity of the recycled material, elemental analysis of the samples was done.
