“…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.…”

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.

“…In 2020 Aranda-García et al [29] studied the main processing and formulation factors that affect the performance of panels manufactured with postconsumer aseptic cartons and HDPE (5 to 20 wt%). Their results showed that mechanical strength depended more on the pressing time than the formulation.…”

Aseptic beverage cartons are multilayer polymer-coated paperboards with a layer of aluminum foil. Due to their multilayer structure it is commonly assumed that they cannot be recycled. This is not the case and this review details the multifarious processes that are used to recycle aseptic beverage cartons. Hydrapulping to recover the paper fibers that constitute 75% of the carton is the most widespread process, followed by the manufacture of construction materials such as boards and tiles which utilize the complete carton. A range of mechanical, chemical and thermal processes are used to separate the PolyAl (polyethylene and aluminum) residual that remains after the paper fibers have been recovered. The simplest process involves agglutination followed by extrusion to obtain pellets that can then be used in industrial and consumer products or combined with other materials such as lignocellulosic wastes. Chemical approaches involve the solubilization of polyethylene and the removal of aluminum. Various thermal processes have also been investigated and a novel microwave-induced pyrolysis process appears the most commercially viable. It is concluded that the focus in future years is likely to be on recycling cartons into construction materials where there is a theoretical yield of 100% compared with 75% for hydrapulping.

“…Literature suggests that milk pouches only accounts to a total of 74 % of total PE waste while the rest comes from PE shopping bags (Aryan et al 2019). Recycling and utilization of such waste for other products can have substantial implications in dealing with the problems associated with such wastes (Aranda-García et al 2020). This waste material can effectively be used as an adhesive for mainly plywood which can also address the issues of formaldehyde emission from such panels along-with the recycling of waste material.…”

Recycling of single use plastic like milk pouches, oil pouches, etc. for high value products can have significant environmental, social and economic implications. The present study focuses on the utilization of waste milk pouches made out of low-density polyethylene as the bonding agent in preparation of plywood panels. Plywood panels with varying content of polymeric content (milk pouch layers) were prepared and evaluated for physical and mechanical properties. The results indicated that with increase in the dosage of milk-pouch content, both physical as well as mechanical properties of the plywood improved substantially. There was nearly three folds difference in modulus of rupture of panel prepared with 80 g/m 2 and 310 g/m 2 polymer content. Similarly, tensile strength, modulus of elasticity also increased significantly with increase in polymer content. The glue shear strength, which is very important for plywood, was found to be influenced by the quantity of polymer. Glue shear strength for panel with 80 g/m 2 polymer was 0,75 MPa which increased to 1,90 MPa in panel with 310 g/m 2 polymer content. It was observed that for strong bonding it is essential that the quantity of polymer should be sufficient enough to penetrate into the pores of wood creating a mechanical interlocking of veneers. The study opens up the scope of recycling of waste milk pouches in the preparation of formaldehyde free plywood.
