The long-term fates of land-disposed plastic waste

Up to 200% underestimation of cumulative methane emission from individual landfills uncovers tens of Tg of overlooked annual emission worldwide

“…For other countries, there is currently no authoritative o cial statistical data available. Therefore, we have adopted the annual waste generation data reported in (Fei et al, 2022;Kaza et al, 2018) and assumed that the annual waste disposal quantity is relatively stable from the operation started time.…”

Transparent, Self-Healing, and Recyclable Biomass-Based Covalent Adaptable Networks Formed via Magnolol and Dynamic Boronate Ester

“…Since the 1950s, humanity has entered an era commonly known as the “Age of Plastic” characterized by the widespread utilization of plastics due to their exceptional performance in both industrial and domestic applications. , According to statistical data, global plastic production exceeds 6300 million tons, with only approximately 9% being recycled . The data underscores a significant issue: the progressive accumulation of fossil-based plastic waste poses an increasingly pressing environmental concern over time. − In pursuit of a sustainable lifestyle, reusing, repairing, and recycling existing materials have become pivotal focal points. , However, there are numerous challenges associated with implementing plastic recycling practices. − One particularly formidable task that has garnered attention from the scientific community is addressing thermosetting plastics . Epoxy resin has garnered significant attention as one of the most prevalent thermosetting resins widely employed in composites, construction, coating, electronics, adhesives, and other industries. − However, similar to other thermosetting resins, it will encounter future challenges pertaining to reprocessing and reshaping capabilities. , In light of this challenge, scientific and industrial objectives are to develop a plastic material that combines the exceptional performance characteristics of thermosetting plastics with the recyclability of thermoplastics, while being derived from environmentally sustainable, renewable, and cost-effective natural resources.…”

Stimuli-cleavable moiety enabled vinyl polymer degradation and emerging applications

“…14 The outcome of this has been a significant proportion of waste plastics finding their way into landfills, being incinerated, or, more alarmingly, accumulating within delicate natural ecosystems. 15 In 2019 and 2020, the International Union of Pure and Applied Chemistry (IUPAC) recognized the plastic degradation technology as one of the ten chemical innovations with the potential to profoundly impact human society in the coming years. 16 Development of viable methods for chemical degrading and recycling of waste plastics would indeed go a long way towards improving material circularity of vinyl polymers.…”
