“…The total worldwide amount of PVB film produced for the automotive and construction industries is estimated at around 170 mil. kg per year [1][2][3][4]. Production lines of world-renowned manufacturers such as Solutia, DuPont, Sekisui, and Kuraray produce thousands of tons of PVB film per year for automotive and construction use, which is further pressed into laminated glass.…”

“…Production lines of world-renowned manufacturers such as Solutia, DuPont, Sekisui, and Kuraray produce thousands of tons of PVB film per year for automotive and construction use, which is further pressed into laminated glass. Worldwide, 65% of all PVB films are used in automotive applications [1,4]. By-products from processed PVB films (5%) and trimmed films (less than 10%) must also be included in the total produced quantities.…”

The Recycling of Waste Laminated Glass through Decomposition Technologies

Laminated glass is ever more frequently used nowadays. This applies to the automobile industry and the construction industry. In cars, this refers mostly to the front and rear windows, whereas in construction, technical safety glass is used for railings and window glass. The task of this type of glass is to provide sufficient resistance against mechanical impact and unpleasant weather conditions. At the same time, if it is damaged, it has to break into the smallest possible pieces, or, wherever possible, the glass should remain intact on the interlayer film to prevent shards from injuring people and animals in the immediate vicinity. The paper deals with the recycling of laminated glass, especially with the effective separation of glass (in the form of cullet) from the polyvinyl butyral (PVB) interlayer film. The experimental research is focused on the mechanical separation of glass from the interlayer film by vibration, and also on the chemical cleaning of PVB film in order to allow subsequent recycling of both materials. The results quantify the efficiency of mechanical separation in the form of weight loss of the sample of laminated glass and define the particle size distribution of glass cullet, which is an important parameter in the possibility of glass recycling. The research leads to a methodology proposal for the separation of glass and PVB film and the design of equipment for this method.

“…In such cases, these parts can be collected and recovered, then submitted to separation processes (polymer protection film) and grinding. The glass powder produced can be incorporated into polymer materials, resulting in composites with different properties [29]. Incorporating mineral loads into PP has been the object of studies on the production of materials with different properties [30,31].…”

Polypropylene (PP) is widely used in short-term use artifacts, rapidly discarded and should partially replace neat PP. In addition, it is one of the polymers most used in the automobile industry. This study shows the technical feasibility of partially substituting neat PP for a post-consumer counterpart (PP r), as well as adding ground glass (GP), used as filler in the polymer matrix. Mechanical and thermal properties of the recycled blends (PP/PP r) and composites (PP/PP r /GP) were evaluated. The results demonstrated that the blend with the highest PP r content obtained a statistically significant decline in elastic modulus, but adding 5 wt% of GP to this blend increased this property, achieving a similar value in relation to neat PP. The composite developed may be a promising tailor-made product with properties resembling those of the virgin plastic. Thus, the automotive industry seems to be a good option for the use of PP r and GP composites and blends, without increasing product requirements.

“…The innovative breaking-crushing machinery allows the separation of those materials during screening. Thus, the resulting effect is detached PVB films in the form of large-sized pieces contaminated by fine glass powder [1][2][3] into the sieved-out shards of glass contaminated by tiny PVB foil slivers. Consequently, PVB contamination excludes waste from new glass production, but the recycled glass can be used once again; for example, the recycled glass may be used as an addition to concrete-based materials or in the insulation of manufacturing glass fibers.…”

This paper presents mechanical and physical properties of light porous aggregates obtained from local waste materials. Granules were produced from a mixture of aluminosilicate-based coalmine slates and car windshield glass that was contaminated by the polyvinyl butyral foil. The initial waste material ratio modification significantly alters physical and mechanical properties of obtained ceramic granules to the extent of the critical amount of added windshield glass powder. The temperature of the heat treatment affects the granules' properties and demonstrates the microstructure and phase crystallization control possibilities. The critical value of the windshield glass concentration was determined to be at a level of 30%, considering the relationship between mechanical and physical properties when large porosity is essential in further application. On the other hand, if the glass-to-slates weight ratio was equal and a sufficient thermal treatment was applied, a core-shell macrostructure formation and occlusion of pores occurred.
