An Overview of Recycling Phenolic Resin

Polymers, Journal Year: 2024, Volume and Issue: 16(9), P. 1255 - 1255

Published: April 30, 2024

Over a century ago, phenolic formaldehyde (PF) resin was developed and continues to increase in yield due its diverse applications. However, PF is thermosetting plastic lacking fluidity moldability, which are nondegradable natural environments, leading severe threats fossil resources as well global environmental crises. As result, recycling extremely important. In this review, we provide the recent advances of resin, includes mechanical recycling, chemical utilization carbon-based materials. The advantages disadvantages each strategy evaluated from green chemistry perspective. This article aims attract interest design, synthesizing, application offering useful suggestions.

Plasma‐Enabled Process with Single‐Atom Catalysts for Sustainable Plastic Waste Transformation

Angewandte Chemie International Edition, Journal Year: 2024, Volume and Issue: 63(50)

Published: Aug. 20, 2024

Abstract The escalating issue of plastic waste generation has prompted the search for an effective solution to address these challenges. In this study, we present a novel plasma‐enabled strategy rapid breakdown various types wastes, including mixtures, into high‐value carbon nanomaterials and hydrogen. H 2 yield selectivity achieved through implemented catalyst‐free are 14.2 5.9 times higher, respectively, compared those obtained with conventional thermal pyrolysis under similar conditions. It is noteworthy that plasma alone approach yields significantly higher energy (g H2 /kWh) other processes. By coupling catalytic process, employing 1 wt . % M /CeO ( =Fe, Co, Ni) atomically dispersed catalysts can further enhance hydrogen production. Specifically, Co/CeO catalyst demonstrated excellent performance throughout 10 cycles decomposition, achieving highest 46.7 mmol/g (equivalent 64.4 theoretical production) nearly 100 atom recovery efficiency at 7 th cycle. Notably, over Fe on CeO surface (1 Fe/CeO ) in integrated plasma‐thermal process comparable particles (10 ). This outcome, single‐atom catalysts, offers promising avenue cost‐effective efficient chemical recycling. Through combination experimental computational efforts, have provided in‐depth understanding mechanisms investigated single developed process. innovative straightforward provides expedient continuously converting diverse streams, mixed contaminated sources, products conducive circular economy.

Design of Copolymer‐Based Blend Compatibilizers for Mixed Plastic Recycling

Macromolecular Chemistry and Physics, Journal Year: 2023, Volume and Issue: 224(24)

Published: Nov. 2, 2023

Abstract Mixed plastic waste recycling represents a significant challenge as the phase separation of different components dictates downgraded performance. Polymer‐based compatibilizers can offer promising solution to address this issue, through effectively reducing surface tension and increasing interfacial strength between distinct result in improved mechanical thermal properties recycled products. This perspective provides an overview fundamental concepts for rational design copolymer blend discusses their recent advances, including both preformed situ generated systems. Impacts key material parameters compatibilizers, such chain topology, chemical composition, block sequence on performance remediating mixed plastics are discussed. Additionally, reactive compatibilization strategies also introduced, formation polymers, installing functional groups plastics, employing dual strategies. Looking forward, there many research technology opportunities area, especially enabling use practically wastes at scale. Specifically, future compatibilizer application should provide strong competitiveness cost energy savings, carbon emission reduction. Together, development is important step establishing circular economy creating more sustainable future.
