The concept of circular economy has been ubiquitous over the past five years and steadily gaining a consensus as new paradigm. Circular covers wide spectrum topics ranging from waste management, through materials to supply chain, amongst which packaging is an essential part for achieving truly economy. It emphasised that resources should be kept in closed loops, thereby generating zero waste. However, largely due nature designated usage, industry built on linear model where designed, produced, consumed disposed of. This creates substantial amount waste, now growing concern earth ecosystem. To enable smooth transition system, design recognised fundamental stepping-stone towards In this study, extensive literature review performed, investigating body research relation paper reviews state-of-the-art design, including rules, guidelines, considerations tools can applied process A framework then proposed, summarising findings showing (i) factors determine material selection, (ii) strategies, guidelines taken into account conceptual development phases, (iii) indicators assist validation assessment circularity. Finally, future trends various aspects facilitate recycling, tools, education policy making are discussed.

Plastic waste has become a serious environmental issue and attracted increasing attention. Various treatment technologies have been developed for the remediation of this waste, including degradation, recycling upcycling, transformation to value-added products extensively studied. Transitioning plastic into carbon-based functional materials is especially attractive because practical applications wastes derived carbon (PWCMs) in field green energy sustainable practices. Herein, recent advances preparation PWCMs are systematically reviewed. Thermal methods synthesizing from summarized, anoxic pyrolysis, catalytic pressure carbonization techniques, flash Joule heating microwave conversion. The PWCMs-based composites storage production (such as batteries, supercapacitors water-splitting systems) concepts (pollutant adsorption/degradation, solar evaporation CO2 capture) detailed, with an emphasis on property-performance correlation. potential future development also examined. This review meant provide insights advanced stimulate upcycling waste.

Plastic and biomass waste pose a serious environmental risk; thus, herein, we mixed with plastic bottle (PET) to produce char composite materials for producing magnetic better separation when used in water treatment applications. This study also calculated the life cycle impacts of preparation adsorbent material 11 different indicator categories. For 1 functional unit (1 kg pomace leaves as feedstock), abiotic depletion fossil fuels global warming potential were quantified 7.17 MJ 0.63 CO2 equiv production materials. The (MPBC) was then remove crystal violet dye from its aqueous solution under various operational parameters. kinetics isotherm statistical theories showed that sorption CV onto MPBC governed by pseudo-second-order, Langmuir models, respectively. quantitative assessment capacity clarifies produced exhibited an admirable ability 256.41 mg g-1. Meanwhile, recyclability 92.4% demonstrated after 5 adsorption/desorption cycles. Findings this will inspire more sustainable cost-effective sorbents, including those derived combined streams.

Abstract Polyethylene terephthalate (PET) is used in textile and packaging industries. The main source of PET production fossil fuels with limited capacity. Also, products are single use that transform into high volumes wastes, causing ecosystem problems. Recycling proposed to confront this challenge. four major recycling techniques mechanical, chemical, pyrolysis, enzymatic. Mechanical, enzymatic have constrained capabilities manage waste. Chemical the potential path expanding waste possibility upcycling addressing dirty streams. Several chemical methods introduced discussed literature. five glycolysis, alcoholysis, aminolysis, ammonolysis, hydrolysis. This review describes depolymerization via these introduces hydrolysis as one can depolymerize an organic‐free solvent environment. Hydrolysis tolerates mixed wastes streams including copolymers. It helps avoid challenges attributed using organic solvents reaction systems. Moreover, produces terephthalic acid, monomer, which has recently gained attention initiative monomer for production. focuses on three forms hydrolysis—alkaline, neutral, by presenting background studies, issued patents, recent trends application
