Опубликована: Авг. 1, 2024

Abstract The escalating accumulation of plastic waste has been developed into a formidable global environmental challenge. Traditional disposal methods such as landfilling and incineration not only exacerbate degradation by releasing harmful chemicals greenhouse gases, but also squander finite resources that could otherwise be recycled or repurposed. Upcycling is kind recycling technology converts high‐value helps to avoid resource pollution. Electrocatalytic upcycling emerges novel distinguished its mild operational conditions, high transformation efficiency product selectivity. This review commences with an overview the employed in management respective advantages inherent limitations are delineated. different types upcycled electrocatalytic strategy then discussed process examined together mechanisms underlying upcycling. Furthermore, structure‐activity relationships between electrocatalysts performance elucidated. aims furnish readers comprehensive understanding techniques for provide guidance design towards efficient transformation.

Impact of Metal Impregnation of Commercial Zeolites in the Catalytic Pyrolysis of Real Mixture of Post-Consumer Plastic Waste

Catalysts, Год журнала: 2024, Номер 14(3), С. 168 - 168

Опубликована: Фев. 24, 2024

This work reports the study of catalytic pyrolysis rejected plastic fractions collected from municipal solid waste whose mechanical recovery is not plausible due to technical or poor conservation issues. The chemical recycling using was carried out over commercial zeolites formulas, i.e., HY and HZSM-5, in which Ni Co metals were deposited at two different loadings (1 5%, wt.). presence these transition on zeolitic supports impacted total production compounds existing liquid oil. samples characterized terms structural, chemical, morphologic properties, fuel (gasoline, light cycle oil, heavy oil) correlated with a combined parameter defined as ratio Acidity/BET area.

Upvaluing chlorinated plastic wastes

Interdisciplinary materials, Год журнала: 2024, Номер unknown

Опубликована: Авг. 14, 2024

Abstract Plastics are a ubiquitous and growing presence in our lives, with chlorinated plastics, like polyvinyl chloride (PVC), playing pivotal role due to their superior qualities. However, the disposal recycling of these materials present significant challenges. The chlorine content can harm catalysts, corrode equipment, create dangerous pollutants, making management plastic waste critical issue efforts. There is pressing need for green, effective, atom‐efficient methods handle this responsibly. This review explores potential converting into valuable resources. We examine four key areas upcycling reusing PVC waste, including innovative separation techniques, leveraging molecular structure, carbon components inherent PVC. By offering thorough analysis current strategies highlighting existing solutions, aims inform inspire further research crucial field, pushing towards more sustainable practices.

The environmental impact of end-of-life PVC flex banners and its potential upcycling opportunities

Waste Management Bulletin, Год журнала: 2024, Номер 2(3), С. 249 - 265

Опубликована: Авг. 27, 2024

PVC is used as a raw material for many products, especially in the production of flex banners. banners advertising or marketing purposes have short-term use [average up to 45 days]. are usually annihilated, piled landfills, incinerated, buried under soil, thus causing severe damage environment. This systematic literature review highlights research carried out on this topic over last two decades and discusses industry practices producing banners, environmental impact due annihilation, reuse recycling methods One these opportunities upcycling, which an important part strategy. These can be reused fashion upcycled products [high-value functional aesthetic products] accessories through zero-waste processes [especially pattern designing cutting stages]. include primarily bags luggage, apparel, footwear, worker uniforms, accessory upcycle products. Based findings from review, it recommends conceptual framework that emphasises end-of-life offers ways avoid piling incineration, burying wastes reducing The studies suggesting upcycling by process not been sufficiently researched reported, they novel method reusing resources.

A Study of Plant-Filled Polymer Composites Based on Highly Plasticized Polyvinyl Chloride

Polymers, Год журнала: 2024, Номер 16(11), С. 1551 - 1551

Опубликована: Май 30, 2024

To enhance the ecological properties of polyvinyl chloride (PVC) products, fabrication PVC-based composites using biofillers with acceptable performance characteristics could be considered. In this work, plant-filled composite materials were fabricated and their optical, structural, thermal, mechanical properties, depending on nature filler, studied. Spruce flour, birch rice husk used as fillers. Optical measurements showed selected technological parameters, allowing films a uniform distribution dispersed plant filler in polymer matrix to obtained. Using fillers PVC leads reduction strength characteristics; for instance, tensile changed from 18.0 MPa (for pure film) ~7 20 wt.% fillers), ~5–6.2 40 fillers). Thermal investigations that samples at low temperatures without changing operating characteristics. Thus, have wide temperature range, from—65 °C 150 °C. TGA analysis has demonstrated affected thermal stability by increasing decomposition resistance. The ability absorb water was observed during investigation absorption samples. And highest degree (up 160 mg/g) detected sample husk. general, based can an equal basis unfilled plastic compounds some applications such construction example, design tasks).
