“…In this regard, several efforts have been reported for rendering the process less-energy demanding by employing organocatalysis, enzymes, and 'green' solvents such as Ionic Liquids (ILs) and Deep Eutectic Solvents (DES) using milder conditions, and in some cases, short reaction times. [81][82][83][84][85][86] Despite the promising results, most of the technologies developed so far, especially compared to mechanical recycling, which is well-established industrially, chemical depolymerization industrialization is still at the lab scale, or, at most, at the pilot stage. Ioniqa Technologies, a spin-off from the Technical University Eindhoven (The Nederland), 87…”

“…The DES formed by ZnCl 2 /Urea procures by itself the acidic media and simultaneously, the interaction between hydrogen of the hydroxyl group and the oxygen of urea molecules, increases the nucleophilic character of oxygen. [ 84 , 85 ] The coordination of PET carboxylic oxygen with zinc promotes electrophilia. PET degradation gives bis terephthalate (2‐hydroxyethyl) monomer (BHET) which is very useful for new syntheses of unsaturated polyester and PET resins.…”

One of the highlights of green chemistry is the development of techniques and procedures with low environmental impact. In the last years, deep eutectic solvents (DES) have become an important alternative to conventional organic solvents. For a period ionic liquids have provoked remarkable interest, but they have been displaced by DES because they show easier preparation methods, lower prices, many of them are biode-gradable and compatible with biological systems. In addition, they show adjustable physicochemical properties, high thermal stability, low volatility and are compatible with water. In this paper is reviewed the state of the art of the use of DES paying special attention to the role of reaction media in organic synthesis.

“…Different treatments have been developed in order to depolymerise PET waste [259,262,263]. The three major chemical routes for depolymerisation are glycolysis [264][265][266][267][268][269], methanolysis [270][271][272][273][274], and hydrolysis [270,[274][275][276][277][278][279][280][281], summarised in Figure 15. For glycolysis and hydrolysis transformations, researchers focussed on the selection of catalysts, which could offer a high yield, short process time, and more environmental friendliness [106,249,282,283].…”

Polyolefins and Polyethylene Terephthalate Package Wastes: Recycling and Use in Composites

et al. 2021

View full text Add to dashboard Cite

Plastics are versatile materials used in a variety of sectors that have seen a rapid increase in their global production. Millions of tonnes of plastic wastes are generated each year, which puts pressure on plastic waste management methods to prevent their accumulation within the environment. Recycling is an attractive disposal method and aids the initiative of a circular plastic economy, but recycling still has challenges to overcome. This review starts with an overview of the current European recycling strategies for solid plastic waste and the challenges faced. Emphasis lies on the recycling of polyolefins (POs) and polyethylene terephthalate (PET) which are found in plastic packaging, as packaging contributes a signification proportion to solid plastic wastes. Both sections, the recycling of POs and PET, discuss the sources of wastes, chemical and mechanical recycling, effects of recycling on the material properties, strategies to improve the performance of recycled POs and PET, and finally the applications of recycled POs and PET. The review concludes with a discussion of the future potential and opportunities of recycled POs and PET.
