The climate crisis calls for a shift from petrochemicals to bio-based products to reduce environmental consequences. Polylactic acid (PLA) is one of the most widely used biopolymers, due to its mechanical properties and renewable origin, to produce bio-based compostable plastic for food packaging. The objective of this... | Categorize the text article into one of the two categories:

One of the key challenges for plastics in a circular economy is its degradation during use, washing and reprocessing. The reduced quality of recycled plastic waste leads to its use in inferior applications. This study presents a novel quality model which incorporates degradation, degree of mixing and contaminations.

A series of Cu/CNT catalysts were applied for CO2 hydrogenation to methanol in three phase reactor. In order to probe the promotion role of copper, catalysts with 0.2, 0.4, and 0.8 wt. % of Cu were synthesized by precipitation method. Different analytical techniques like Inductively Coupled Plasma-Optical Emission Spec... | Categorize the text article into one of the two categories:

The environmental impact of packaging has already been studied since the early development of the life cycle assessment (LCA) methodology, and today an extensive amount of studies exists. LCAs inform policy makers and guide companies in developing more environmentally sustainable packaging. From both a policy and a bus... | Categorize the text article into one of the two categories:

Plastic pollution is a pressing global concern due to its severe environmental impacts. Thus, the adoption of sustainable practices in product design and end-of-life management has become paramount towards a plastic's circular economy. This study delves into the transformative potential of design for recycling by exami... | Categorize the text article into one of the two categories:

The distribution of liquid detergents through self-dispensing systems has been adopted in some Italian retail stores over the last few years. By enabling the consumer to refill several times the same container, it is proposed as a less waste-generating and more environmentally friendly alternative to the traditional di... | Categorize the text article into one of the two categories:

The performance of ZSM-5, γ-Al2O3 and WO3/SiO2 catalysts for the dehydration of methanol was studied in a fixed bed reactor over a temperature range of 150 to 450 °C and at atmospheric pressure. A parallel reaction scheme for dehydration of methanol to dimethyl ether and methane was proposed for the WO3/SiO2 catalyst, ... | Categorize the text article into one of the two categories:

Although the high efficiency of the homogeneous processes, using rhodium or iridium complexes, was clearly demonstrated industrially, heterogeneous catalysts offer the advantages of facile product separation and vapor phase operation, which often limit catalyst losses.

Using the synthesis method, we produced a series of 2‑hydroxy-4-benzyloxybenzylidene N- or S-alkyl chains substituted thiosemicarbazones and their dioxomolybdenum(VI) complexes containing long alkyl chains (pentyl, hexyl, heptyl, and octyl). A series of dioxomolybdenum(VI) complexes with 2‑hydroxy-4-benzyloxybenzyliden... | Categorize the text article into one of the two categories:

Au@Pt core–shell nanoparticles were successfully synthesized by successive reduction of HAuCl4 and H2PtCl6 and were then assembled on Vulcan XC-72 carbon surface (noted as Au@Pt/C). The morphology and distribution of Au@Pt nanoparticles were characterized by UV–vis spectroscopy, transmission electron microscopy (TEM), ... | Categorize the text article into one of the two categories:

SAPO-34 molecular sieves synthesized using calcined kaolin as partial raw material under three-stage of high-low-high temperature hydrothermal condition are explored systematically. Especially, the effect of kaolin calcination temperature on the crystallization mechanism of SAPO-34 and the methanol to olefin performanc... | Categorize the text article into one of the two categories:
