“…Other researchers, as Wu et al [46], obtained a TTI of 24 s for ABS with a 50 kW/m 2 external heat flux, which is in line with our result. A different TTI time for ABS shows that for a comprehensive approach, several factors have to be considered, as for example: the monomers (acrylonitrile, butadiene-styrene) concentration [47], the manufacturing method, the products supplier (i.e., with regard to their purity, chemical composition etc.) or the external heat flux value of the cone calorimeter.…”

In this paper an experimental investigation on fire retardancy of a new polymer nanocomposite derived from organic montmorillonite and exolit fire retardant in an acrylonitrile- butadiene-styrene copolymer by analyzing the flammability and fire behavior is described. The samples were prepared by melting and mixing nanocomposites and fire retardant in different concentrations in an acrylonitrile-butadiene-styrene base polymer. It was found that using only one component (organic montmorillonite or fire retardant) the burning stops in 10 s on the sample. Confirmation of synergy in flammability by combining both montmorillonite and flame retardants was noticed and is discussed regarding the flame-retardant mechanisms assessed by means of the Limiting oxygen index (LOI), UL 94, and cone-calorimeter methods. The acrylonitrile- butadiene-styrene preparation with 15–20 wt% fire retardant and 1–2 wt% organic montmorillonite reached a UL-94 V-0 classification, contrasting with the pure acrylonitrile- butadiene-styrene and the acrylonitrile-butadiene-styrene with 15 wt% fire retardant and acrylonitrile-butadiene-styrene with 1–2 wt% organic montmorillonite formulations, which completely burned. Finally, the samples showed a very good synergy going to a higher reduction of the peak heat release rate and to a minimum mass reduction, as obtained from cone calorimeter tests.

“…The properties of the produced composite material mainly depend on the percentage of the butadiene in the initial polymer, which varies between 3-10 mol%. It is widely used in electrical and electronic equipment, in construction and packaging materials and in storage bottles, appliance parts, housewares, and interior parts in household electronics [48].…”

“…Marcilla and his team [52,48] also worked on the catalytic pyrolysis of mixtures of Al-MCM-41 catalysts and a series of polymers and copolymers with a styrene base by the means of thermogravimetric analysis, and they reported that the mesoporous catalysts appear to be interesting in the process of HIPS thermal degradation. In a published paper of 2007 [52] they studied, with the thermogravimetric technique, the effect of parameters such as particle size and method of contact between polymer/catalyst in the HIPS pyrolysis.…”

In a later study of 2009 [48] they also studied the pyrolysis of a series of polystyrene/polybutadiene copolymers in the presence of Al-MCM-41 in an attempt to compare their behaviour in the pyrolysis process with that of HIPS. Results have shown the importance of parameters such as the copolymer structure, the flow characteristics and the method of contact between the polymer and the catalyst in the pyrolysis process.…”

The production of electric and electronic equipment (EEE), including personal computers, compact disks, TV sets, refrigerators, washing machines, toasters and many other daily-life items, is one of the fastest growing areas of manufacturing industry today. The rapid development in the EEE technology combined with a short life cycle and a variety of uses, at least for most of the products, poses a significant issue as far as their disposal is concerned. This has resulted in a continuous increase of Waste Electric and Electronic Equipment (WEEE) with some representative numbers: in the EU only, 9.5 million tones have been disposed in 2008 and this is expected to increase to 12.3 million tones in 2020 [1, 2]. While there is no generally accepted definition of electronic waste in most cases electronic waste consists of electronic products that were used for data processing, telecommunications, or entertainment in private households and businesses and are now considered obsolete, broken, or unrepairable (Figure 1). Despite its common classification as a waste, disposed electronics are a considerable category of secondary resource due to their significant suitability for direct reuse and material recycling. In view of the environmental problem involved in the management of WEEE, many countries and organizations have drafted national legislation to improve the reuse, recycling and other forms of recovery of such wastes so as to reduce disposal. The EU in an attempt to deal with the necessity of a meaningful recycling system and at the same time to preserve oil and fossil fuel resources has introduced 2002/96/EC directive [2], which demands 70-80% of WEEEs to be recovered in the form of energy and/or materials [2]. The directive aims at the minimization of the percentage of the solid wastes which will be landfilled or incinerated the full conversion of all waste streams (including plastics) through thermal or mechanic treatment by 2020.

“…7 Within the types of polystyrene (PS), high impact polystyrene (HIPS) corresponds to 30-40% of the worldwide PS production, finding applications in packaging, containers, appliance parts, household items and electronic equipment. [8][9][10][11][12] Actually, the waste produced by electronic equipment, known as "waste electrical and electronic equipment" (WEEE), reached 59 million tons by 2022, with HIPS representing 42% of all WEEE. 13,14 Current valorization techniques for polyolefins (including PS) involve pyrolysis reactions, perhaps the most common approach, 15 metathesis reactions, like ethenolysis, 16 hydrogenolysis over metal catalysts, 17 hydrocracking over bifunctional catalysts, 18 among others.…”
