In recent years, the issues of polymer pollution and carbon footprints have stirred up an active debate around the future of petrochemical industry, which over the past 50 years has been a significant driver of global oil demand. It is assumed that the transition to a "circular plastic economy" should resolve environmental issues for the industry, simultaneously eliminating its dependence on petroleum feedstock. In this work, the authors attempted to untangle the concept of "circular plastics" and assess its potential impact on the market of liquid hydrocarbons. Even in the Moderate scenario, the "circular plastics economy" does become an important factor in demand for hydrocarbons in petrochemical industry, reducing it by 5-10% of the business-as-usual case by 2050 and greatly slowing down demand growth rates after 2045, and the more drastic scenario even sees hydrocarbon demand peak by 2040. These findings indicate the importance of taking into account "plastics circularity" when making long-term forecasts of global oil market.

The growing pursuit of carbon circularity in material fabrication has led to the increased use of recycled and biobased resources, especially in epoxy resin systems. Fossil-based bisphenols are being replaced with recycled bisphenol A (r-BPA) and lignin derivatives, both derived from previous processes. In this study, r-BPA was chemically recycled from end-of-life televisions, then converted into r-DGEBA and r-DAGBA through glycidylation and acrylic acid ring-opening.

Through a natural experiment setting in Hong Kong, this study examines the effects of financial incentives and nudges on consumer choices among three types of coffee cups: bring-your-own-cup (BYOC), shop-provided reusable cups, and disposable cups. Our dataset comprises 223 structured observations of coffee shops with 522 data points. The financial incentive-a direct price instrument set as a discount-is offered exclusively to customers who bring their own cups, while shop-provided (reusable) cups are not eligible.

Article Synopsis
- The paper focuses on optimizing FDM (Fused Deposition Modeling) parameters, specifically layer height (L) and infill density percentage (I), for creating tensile and compression samples from recycled PETG and ASA materials.
- The study employs value analysis to balance mechanical strength and production cost, revealing that layer height primarily affects tensile samples made from rPETG, while infill density is crucial for rASA samples.
- Ultimately, the research identifies optimal FDM settings (L = 0.20 mm and I = 100%) for producing parts from recycled materials, supporting circular economy practices in manufacturing.
