“…In this framework, several recycling methodologies have been proposed and industrially implemented over the years, which have been recently reviewed by Robertson [4]. These approaches can be broadly divided in two families: a first family includes those that reprocess cartons as a mixture (incineration, gasification, pyrolysis) for energy recovery [5] or for manufacturing construction boards by hot compression [6][7][8], while the second one involves the removal of the cellulosic part in a previous step. In this case, which is the most common recycling strategy at an industrial level, the removal of cellulosic fraction is accomplished by hydrapulping in paper mills thanks to centrifugal forces and water.…”

Effect of Basalt Fibres on Thermal and Mechanical Properties of Recycled Multi-Material Packaging

The low-density polyethylene (LDPE)/aluminium mix obtained after the recovery of cellulose from multilayer aseptic packaging used in the food and beverage industry is generally destined for energy recovery. In this work we propose it as a matrix for value-added composite materials. A commercially available material (EcoAllene) obtained from multilayer packaging recycling was reinforced with short natural basalt fibres up to 30 wt.% by twin screw extrusion, aiming at improving the mechanical profile of such material and widening its applications. Thermal characterizations by thermogravimetric analysis and differential scanning calorimetry showed that the material is indeed a complex mixture of LDPE, HDPE, PP, and aluminium. Basalt fibres did not modify the melting and crystallization profile as well as the global degradation behaviour. Composites were then subjected to tensile, bending, Charpy impact tests and the fracture surfaces were investigated by scanning electron microscopy. Results highlighted a beneficial effect of basalt fibres to stiffness and strength in both loading conditions, with improvements by 107% and 162% for tensile and bending strength, respectively, which were linked also to a 45% enhancement of impact strength. This increased mechanical performance is promising for their use in automotive interiors and outdoor decking applications.

“…By means of trial and error and using thermodynamical analyses, they did conclude that char obtained from pyrolysis at 600°C at a 3 h procedure demonstrated the most promising mercury adsorption capacity at 21.0 mg/g. The field of char absorbents is still expanding with hopes of Tetra Pak pyrolysis chars acting as major absorbents for industry in the future [41].…”

Waste Material Recycling in the Circular Economy - Challenges and Developments

View full text Add to dashboard Cite

This chapter presents an overview of current trends in plastic recycling and focuses on specific topics of interest. Firstly, there are presented all methods used for plastic recycling, along with the advantages and disadvantages of each method. Extra attention is paid to chemical recycling and especially, pyrolysis (thermal and catalytic), which is an environmentally friendly method that results in the formation of value-added products. Emphasis is given on three case studies where there are difficulties as regards the recycling of the plastic part: polymeric blends, since the existence of mixed plastic wastes may be challenging for their recycling; plastics originating in multilayer packaging, since the multilayer packaging consists of various materials, including plastics, paper, and metals that may be an obstacle for the recycling of the plastic part; and brominated flame-retarded plastics from waste electric and electronic equipment (WEEE), since in this case safe handling is required in order to avoid environmental contamination and a pretreatment step before recycling may be of paramount importance. These three case studies along with the mentioned difficulties and suggestions in order to overcome them are presented here, with the aim of offering insights for future studies on the management of plastic materials.

“…Uma parcela significativa das embalagens cartonadas pós consumo, tem sua destinação para aterros sanitários. Assim, a reciclagem dessas embalagens se faz necessária para reduzir os impactos ambientais da geração de resíduos, para que dessa forma, possa recuperar os materiais contidos nas embalagens cartonadas possam ser inseridos ou reutilizados nos processos de produção, reduzindo a necessidade de exploração dos recursos naturais (HAYDARY et al, 2013;ZÚÑIGA-MURO et al, 2021). Porém os processos de reciclagem dessas embalagens, são prejudicadas pela sua composição e ao custo do processo (KRAUKLIS et al, 2021;DELVERE et al, 2019).…”
