Plastic production has been rapidly growing across the world and, at end of their use, many plastic products become waste disposed in landfills or dispersed, causing serious environmental and health issues. From a sustainability point view, conversion to fuels or, better yet, individual monomers, leads much greener management compared landfill disposal. In this paper, we systematically review potential pyrolysis as an effective thermochemical method for valorization waste. Different types, along with influence operating conditions, e.g., catalyst temperature, vapor residence time, on yields, quality, applications cracking are discussed. The quality oil, before after upgrading, is conventional diesel fuel. oil yields high 95 wt.% can be achieved through slow pyrolysis. heating value approximately equivalent that fuel, i.e., 45 MJ/kg, no sulfur, very low water ash content, almost neutral pH, making it promising alternative petroleum-based fuels. This as-is minor modifications, readily used engines. Fast mainly produces wax rather than oil. However, presence suitable catalyst, waxy further crack into Wax intermediate feedstock fluid catalytic (FCC) units produce fuel other valuable petrochemical products. Flash waste, performed temperatures, near 1000 °C, short times, less 250 ms, recover up 50 ethylene monomers from polyethylene Alternatively, pyrolytic olefins two stages, followed by thermal second stage. carbon nanotubes, representing higher-value product also discussed detail. results indicate 25 converted nanotubes.

Abstract Plastic waste remains a global challenge due to the massive amounts being produced without satisfactory treatment technologies for recycling and upcycling. Photocatalytic processes are emerging as green promising approaches upcycle plastics into value‐added products under mild conditions using sunlight energy source. In this review, recent advances in plastic conversion through photocatalysis have been comprehensively summarized. Special emphasis is placed on photocatalytic mechanism selective CC CH bond transformations of access fuels, chemicals, materials. Finally, challenges perspectives establishing new paradigm toward sustainable circular economy also put forward.

Energy from renewable resources is central to environmental sustainability. Among the renewables, sunlight-driven fuel synthesis a sustainable and economical approach produce vectors such as hydrogen through water splitting. The photocatalytic splitting limited by oxidation half-reaction, which kinetically energetically demanding entails designer photocatalysts. Such challenges can be addressed employing alternative half-reactions. Photoreforming drive breakdown of waste plastics biomass into valuable organic products for production H2. We provide an overview photoreforming its underlying mechanisms that convert polymers H2 fuels fine chemicals. This paramount importance two complementary perspectives: (i) green energy harvesting (ii) sustainability decomposing valuables. Competitive results generation without hazards are being generated. process, mechanisms, critical assessment field scarce. address points focusing on concept up-to-date knowledge with key milestones achieved, uncovering concepts in photoreforming, (iii) design photocatalysts pathways use different polymer wastes substrates.

A general rise in environmental and anthropogenically induced greenhouse gas emissions has resulted from worldwide population growth a growing appetite for clean energy, industrial outputs, consumer utilization. Furthermore, well-established, advanced, emerging countries are seeking fossil fuel petroleum resources to support their aviation, electric utilities, sectors, processing essentials. There is an increasing tendency overcome these challenging concerns achieve the Paris Agreement’s priorities as technological advances energy technologies progress. Hydrogen expected be implemented various production applications fundamental future carrier materials development manufacturing processes. This paper summarizes recent developments hydrogen refining, hydrocarbon processing, manufacturing, pharmaceuticals, aircraft construction, electronics, other applications. It also highlights existing industrialization scenario describes prospective innovations, including theoretical scientific advancements, green raw production, potential exploration, renewable resource integration. Moreover, this article further discusses some socioeconomic implications of resource.
