“…To facilitate the identification and sorting of different types of polymer residues in PW, several companies determine the plastic types present in their manufactured products by a numerical symbol system. 14 The first identification code was suggested by the Society of Plastics-Society of Plastics Industry, Inc. in 1988 due to a request from recycling companies. 68 A similar numerical coding system is established in Brazil by Brazilian Association of Technical Standards with the Standard NBR 13230 (2008).…”

Several researches and technologies on polymer recycling have been driven and justified by the uncontrolled and crescent polymer waste generation in the world. Herein, a critical and concise review on the recent and well-established recycling practices for polymer waste is presented, taking into account not only thermoplastics (or plastics) but also thermosets and elastomers. Moreover, sorting and characterization techniques for polymer waste recycling are detailed and their importance is discussed. An in-depth analysis of the literature indicated that novel and advanced recycling methods for polymeric waste (PW) present difficulties to be applied in the industrial sector, mainly the scientific innovations in the chemical recycling area. In the current scenario, new challenges for the recycling sector are linked to highly contaminated PW from electrical, electronic, and medical products.

“…• Secondary -mechanical reprocessing to lower value products (downgrading) [7,9] • Tertiary -chemical recycling to recover petrochemical components in plastics [9,10,11] • Energy recovery (incineration) -of limited value because energy recovered as heat is a fraction of energy conserved by recycling [12] Several recent reviews have focussed on thermoplastic polymer recycling covering the aforementioned 4 main methods [7,8,9,13] and discussing the opportunities, benefits and disadvantages of each. Specifically, El Mehdi Mekhzoum et al [13] present technological and economic issues preventing increased volumes of thermoplastic waste being recycled in addition to the varied methods and options that can, and are, used to recover plastic resources.…”

It is reported that plastic waste is accumulating in the oceans at an alarming rate. A significant proportion of this waste is plastic packaging materials, even though recycling routes and options are available to retain and reuse this oil-based resource. In addition to thermoplastic materials, fibre reinforced polymer materials are finding increased use and soon will become a concern with respect to disposal. This review presents current research and technology that aims to embrace plastics and polymer composites into a circular economy. The benefits and challenges associated with polymer recycling are highlighted, not least being the strategies required to encourage industry and society to recycle resources rather than dispose and renew.

Strategic Approach Towards Plastic Waste Valorization: Challenges and Promising Chemical Upcycling Possibilities

et al. 2021

View full text Add to dashboard Cite

Plastic waste, which is one of the major sources of pollution in the landfills and oceans, has raised global concern, primarily due to the huge production rate, high durability, and the lack of utilization of the available waste management techniques. Recycling methods are preferable to reduce the impact of plastic pollution to some extent. However, most of the recycling techniques are associated with different drawbacks, high cost and downgrading of product quality being among the notable ones. The sustainable option here is to upcycle the plastic waste to create high-value materials to compensate for the cost of production. Several upcycling techniques are constantly being investigated and explored, which is currently the only economical option to resolve the plastic waste issue. This Review provides a comprehensive insight on the promising chemical routes available for upcycling of the most widely used plastic and mixed plastic wastes. The challenges inherent to these processes, the recent advances, and the significant role of the science and research community in resolving these issues are further emphasized.
