“…The results showed that the blends were more flexible than pure PLA, whereas the tensile strength, Young's modulus, and glass transition temperature of pure PLA were higher than those of the blends (Figure 17). The decreasing T g with increasing PTMC content in the blend indicated the compatibility between the two components (PLA, PTMC) [76,77]. The greater flexibility of the blends compared to pure PLA made them more suitable for covering the wound where the stiff film of pure PLA could not be covered freely over the wound when it was implanted in the body.…”

Abstract. Polylactic acid (PLA), one of the well-known biodegradable polyesters, has been studied extensively for tissue engineering and drug delivery systems, and it was also used widely in human medicine. A new method to synthesize PLA (ring-opening polymerization), which allowed the economical production of a high molecular weight PLA polymer, broadened its applications, and this processing would be a potential substitute for petroleum-based products. This review described the principles of the polymerization reactions of PLA and, then, outlined the various materials properties affecting the performance of PLA polymer, such as rheological, mechanical, thermal, and barrier properties as well as the processing technologies which were used to fabricate products based on PLA. In addition, the biodegradation processes of products which were shaped from PLA were discussed and reviewed. The potential applications of PLA in the medical fields, such as tissue engineering, wound management, drugs delivery, and orthopedic devices, were also highlighted.

“…In another report the depolymerization of PC in subcritical and supercritical toluene had been reported [7] . In the meantime, some other publications have been shown PC recycling, alone or blended with other polymers, which have their own merits and drawbacks [8][9][10][11][12][13][14][15][16] .…”

Hydroglycolysis of polycarbonate waste from used compact discs was developed to recover Bisphenol-A (BPA) as a valuable material. Experiments were done in glycerin and water as an alternative green solvent. The effect of solvent ratios has been studied to evaluate BPA recovery. The use of 30% aqueous glycerin (pbw) led to 93 and 100% of BPA at reflux condition within 1.0 and 5.5 hours, respectively. Recovered BPAs were identified by spectroscopy methods and the results were compared with commercial sample data.

“…Approximately 15 million tonnes of the used plastic waste are generated every year across Europe. Of this volume, a mere 7% [1][2][3] is recycled and the remainder is deposited or incinerated [4]. Polyethylene terephthalate (PET, systematic name poly(oxy-1,2-ethanediyloxycarbonyl-1,4-phenylenecarbonyl)) is a highly thermally stable polymer with many uses, most frequently as packaging material for beverages [5] in the form of the well known PET bottles.…”
