It is difficult to reuse wastes from polymers due the mismatch between amount of contaminants and secondary quality feed. This type operation much more expensive cost-effective than production polymer raw materials latest materials. However, recyclable beneficial if used extensively in various concrete products wood-polymer boards. done only cleaning sorting are not particularly important for products. Polyethylene terephthalate (PET) a widely industries its excellent physical chemical properties. Besides, increasing use PET has led global crisis waste management, as improper disposal caused significant environmental damage. major source accumulated landfills, address this issue, recycling methods have evolved. In regard, present review examines techniques involved PET. Conventional influence diverse depolymerization reaction variables were discussed, upsides downsides each technique considered. The summarizes advances technologies plastic waste, focusing on bio-recycling PET, aiming sustainable, economical solutions circular economy.

Plastic production has increased dramatically, leading to accumulated plastic waste in the ocean. Marine plastics can be broken down into microplastics (<5 mm) by sunlight, machinery, and pressure. The accumulation of organisms release additives adversely affect health marine organisms. Biodegradation is one way address pollution an environmentally friendly manner. microorganisms more adapted fluctuating environmental conditions such as salinity, temperature, pH, pressure compared with terrestrial microorganisms, providing new opportunities pollution. Pseudomonadota (Proteobacteria), Bacteroidota (Bacteroidetes), Bacillota (Firmicutes), Cyanobacteria were frequently found on biofilms may degrade plastics. Currently, diverse plastic-degrading bacteria are being isolated from environments offshore deep oceanic waters, especially Pseudomonas spp. Bacillus Alcanivoras Actinomycetes. Some fungi algae have also been revealed degraders. In this review, we focused advances biodegradation their enzymes (esterase, cutinase, laccase, etc.) involved process polyethylene terephthalate (PET), polystyrene (PS), (PE), polyvinyl chloride (PVC), polypropylene (PP) highlighted need study sea.

The accumulation of synthetic plastic waste in the environment has become a global concern. Microbial enzymes (purified or as whole-cell biocatalysts) represent emerging biotechnological tools for circularity; they can depolymerize materials into reusable building blocks, but their contribution must be considered within context present management practices. This review reports on prospective bio-recycling framework Europe. Available biotechnology support polyethylene terephthalate (PET) recycling. However, PET represents only ≈7% unrecycled waste. Polyurethanes, principal fraction, together with other thermosets and more recalcitrant thermoplastics (e.g., polyolefins) are next plausible target enzyme-based depolymerization, even if this process is currently effective ideal polyester-based polymers. To extend to circularity, optimization collection sorting systems should feed chemoenzymatic technologies treatment mixed In addition, new bio-based lower environmental impact comparison approaches developed (available new) materials, that designed required durability being susceptible action enzymes.

The presence of microplastics (MPs) is increasing at a dramatic rate globally, posing risks for exposure and subsequent potential adverse effects on human health. Apart from being physical objects, MP particles contain thousands plastic-associated chemicals (i.e., monomers, chemical additives, non-intentionally added substances) captured within the polymer matrix. These are often migrating MPs can be found in various environmental matrices food chains; health effects. In addition to attributes MPs, plastic surfaces effectively bind exogenous chemicals, including pollutants (e.g., heavy metals, persistent organic pollutants). Therefore, act as vectors pollution across air, drinking water, food, further amplifying posed by exposure. Critically, fragmentation plastics environment increases risk interactions with cells, available leach adsorb transfer pollutants. This review proposes so-called triple nexus approach comprehensively map existing knowledge interconnected particles, Based data, there large gap regard cumulative nexus. Each component known induce genotoxicity, inflammation, endocrine disruption, but about long-term inter-individual lacking. Furthermore, not readily excreted organisms after ingestion they have been accumulated blood, cardiac tissue, placenta, etc. Even though number studies MPs-associated impacts rapidly, this underscores that pressing necessity achieve an integrated assessment MPs' order address future gaps.

Abstract Plastic waste is an environmental challenge, but also presents a biotechnological opportunity as unique carbon substrate. With modern tools, it possible to enable both recycling and upcycling. To realize plastics bioeconomy, significant intrinsic barriers must be overcome using combination of enzyme, strain, process engineering. This article highlights advances, challenges, opportunities for variety common plastics.

Abstract Plastic pollution is becoming a major health issue due to the recent discovery of microplastics and nanoplastics in living organisms environment, calling for advanced technologies remove plastic waste. Here we review enzymes that degrade plastics with focus on properties, protein engineering polymers such as poly(ethylene terephthalate), poly(butylene adipate-co-terephthalate), poly(lactic acid), polyamide polyurethane.
