Polyethylene terephthalate (PET) is one of the most widely used plastics globally, predominantly found in packaging, textiles, and consumer products. As plastic waste continues to accumulate, the environmental burden associated with PET becomes increasingly pressing. Traditional recycling methods often fall short of addressing the challenges posed by PET's durability and resistance to biodegradation. This Collection seeks to explore innovative biorecycling strategies, including enzymatic depolymerization and microbial bioconversion, which can efficiently convert PET waste into valuable materials and chemicals, offering a sustainable solution to plastic pollution.

Advancements in the biorecycling of PET have shown promising results in recent years. Researchers are uncovering novel enzymes, such as cutinases and PET hydrolases, that can break down PET more efficiently than conventional methods. These breakthroughs not only enhance the recyclability of PET but also contribute to the development of a circular economy in plastics, thereby reducing the environmental footprint of polyester plastics. By fostering interdisciplinary collaboration, this research area holds the potential to revolutionize waste management practices and mitigate the impacts of plastic pollution.

Continued exploration in this field may lead to even more efficient biocatalysts and integrated waste management systems that could transform PET waste into renewable resources. Innovations in synthetic biology and metabolic engineering may also pave the way for microorganisms that can fully degrade PET and other polyester plastics, leading to sustainable and environmentally friendly alternatives to traditional recycling methods.

Potential topics for submission include, but are not limited to:

• Enzymatic depolymerization of PET

• Microbial bioconversion of plastic waste

• Development of recycled PET (rPET) materials

• Environmental impact of plastic recycling

• Circular PET economy strategies

Metal-organic frameworks (MOFs) have emerged as a groundbreaking class of porous crystalline materials, renowned for their remarkable tunability and high surface area. These versatile structures have garnered significant attention in recent years due to their potential applications in energy storage technologies, such as batteries, supercapacitors, and fuel cells. The unique properties of MOFs, including their adjustable porosity and selective adsorption capabilities, make them ideal candidates for enhancing the performance and efficiency of energy storage systems. As the global demand for sustainable energy solutions continues to rise, understanding and harnessing the capabilities of MOFs is more crucial than ever.

Advances in the field have demonstrated that MOFs can significantly improve the electrochemical performance of energy storage devices. Researchers are actively investigating various MOF compositions and structures to optimize energy density, charge-discharge rates, and overall efficiency. Recent studies have highlighted the potential of integrating MOFs into lithium-ion, lithium-sulfur, and lithium-air batteries, showcasing improvements in cycle stability and capacity retention. As the world shifts towards cleaner energy solutions, developing efficient energy storage systems through MOFs will play a vital role in addressing the challenges posed by intermittent renewable energy sources.

Continued research in the applications of MOFs in energy storage may lead to breakthroughs that enhance energy efficiency and performance. Future investigations might focus on the design of novel MOF materials that can facilitate faster charge and discharge cycles while maximizing energy density. Additionally, innovations in the integration of MOFs with other nanomaterials could pave the way for hybrid systems that leverage the strengths of each component, ultimately contributing to a more sustainable and reliable energy landscape.
