Abstract:

During mechanical recycling several mechanical treatments are used to degrade textile waste and make it ready for new application in different other industries. Mechanical recycling process consists of several work steps. Pre or post-consumer textile waste is firstly cut in small pieces by a shredding machine. Blending boxes with different storage capacities are used to blend cut textile waste. A feeding unit is placed in between a blending box and a tearing machine. Tearing machines separate individual fibers by tearing small pieces of shredded textile material apart. At the end of the textil

Abstract:

The increase in waste has motivated the adoption of the circular economy concept, which assumes particular relevance in the case of plastic materials. This has led to research of new possibilities for recycling plastics after their end-of-life. To achieve this goal, it is fundamental to understand how the materials’ properties change after recycling. This study aims to evaluate the thermal and mechanical properties of recycled plastics, namely polycarbonate (PC), polystyrene (PS), glass fibre-reinforced polyamide 6 (PA6-GF30), and polyethylene terephthalate (PET). With this purpose, injected s

Abstract:

Solvent-based and mechanical recycling technology approaches were compared with respect to each process’s decontamination efficiency. Herein, post-consumer polystyrene (PS) feedstock was recycled by both technologies, yielding recycled PS resins (rPS). The process feedstock was subjected to four recycling cycles in succession to assess the technology perennity. The physico-chemical and mechanical properties of the rPS were then evaluated to discern the advantages and drawbacks of each recycling approach. The molecular weight of the mechanically recycled resin was found to decrease by 30% over

Abstract:

The textile industry is among the world’s largest, producing an estimated 124 million tonnes of fibres in 2023, with more than half of these being made from virgin polyester. Less than 0.1% of polyester fibres are recycled into new textiles at the end of their lives. Mechanical, thermo-mechanical, and chemical textile-to-textile polyester recycling are all technically possible, but thermo-mechanical recycling is reported to provide the most promising compromise between cost and quality. Myriad chemicals are used in polyester production, and this paper is the first to review the related academi

Abstract:

Biocomposites, made from biobased polymers with natural fibre reinforcement, offer a feasible path towards environment friendly and sustainable materials. However, biocomposites have struggled to attract ta market that is mostly dominated by conventional fossil-based polymers. To increase the cost efficiency and extend the lifespan of biocomposites, the effects of mechanical recycling on their properties should be thoroughly explored. While there has been some research on recycling natural fibre-reinforced biocomposites, limited attention has been paid to biocomposites reinforced with softwood

Abstract:

During the last decade, the consumption of plastics has increased highly in parallel with plastic waste. The transition towards a circular economy is the only way to prevent the environment from landfilling and incineration. This review details the recycling techniques with a focus on mechanical recycling of polymers, which is the most known and developed technique in industries. The different steps of mechanical recycling have been highlighted, starting from sorting technologies to the different decontamination processes. This paper covers degradation mechanisms and ways to improve commodity

Abstract:

The excessive amount of global plastic produced over the past century, together with poor waste management, has raised concerns about environmental sustainability. Plastic recycling has become a practical approach for diminishing plastic waste and maintaining sustainability among plastic waste management methods. Chemical and mechanical recycling are the typical approaches to recycling plastic waste, with a simple process, low cost, environmentally friendly process, and potential profitability. Several plastic materials, such as polypropylene, polystyrene, polyvinyl chloride, high-density poly

This study investigates the effect of recycling/reprocessing on the physical and mechanical properties of composites based on radiata pine (Pinus Radiata) fibre and polypropylene (PP) with a maleated polypropylene (MAPP) coupling agent, produced using a twin-screw extruder, followed by injection moulding. Composites containing 40wt% fibre and 4wt% MAPP were assessed mechanically and thermally, as well as for moisture absorption after being recycled up to eight times. Both the tensile strength (TS) and Young’s modulus (YM) of composites were found to decrease linearly from 41 MPa and 4556 MPa r

Abstract:

Poly(lactic acid) (PLA) is a biobased polymer that represents one of the most interesting alternatives to fossil-fuel based polymers in food packaging applications. Most of the PLA used in food packaging is used only once and then discarded, even though the PLA types used in packaging have good properties and stability. Therefore, it seems reasonable to consider the possibility of recycling the used polymer through a mechanical recycling process. The main aims of this work are to study the effect of the mechanical recycling on the properties of PLA and the usefulness of different upgrading met

Abstract:

The rapid growth of the wind energy industry has resulted in a significant increase in Wind Turbine Blade (WTB) waste, posing challenges for recycling due to the composite materials used in their construction. Several proposed techniques, including mechanical, thermal, and chemical processes, have been considered for wind-blade recycling, but determining the most effective approach remains a critical issue. This study presents the first comprehensive systematic review of available wind-blade recycling processes, evaluating their economic, technical, and environmental performance. Additionally,

Abstract:

The cold recycled materials have temperature sensitivity; both the modules and the strength will decrease with the increase of temperature, which will change the mechanical state of pavement structure. The temperature sensitivity of cold recycling materials may produce failure. Two typical pavement structures, which have been used in practical project, were selected in the analysis. The result shows that the mechanical state of cold recycling pavement without semi-rigid base will be improved in hot summer, while the mechanical state of the cold recycling pavement without semi-rigid base will b

Abstract:

Analogue materials are widely used to simulate prototype rocks in geo-mechanical model tests. The large amounts of solid waste generated by a large-scale model test has always posed problems for studies. The re-use of analogue materials can significantly reduce the cost of geo-mechanical model tests and the resulting environmental problems. However, despite the environmental and economic benefits, there have been few reports on the re-use of analogue materials. In this work, a recycling method for a resin-based analogue material is studied experimentally. More than 300 samples were prepared an
