“…The use of commonly available conventional fillers (both particulate and fibrous) such as glass fibers, [229] talc, [230,231] calcium carbonate, [232] etc. has been well documented in packaging polymers to cause improvements in mechanical properties such as tensile strength and modulus, thermal properties such as heat deflection temperature and thermal resistivity, electrical properties, etc.…”

Plastics around the globe have been a matter of grave concern due to the unavoidable habits of human mankind. Taking waste statistics in India for the year 2019–20 into account, the data of 60 major cities show that the generation of plastic waste stands tall at around 26,000 tonnes/day, of which only about 60 % is recycled. A majority of the non‐recycled plastic waste is petrochemical‐based packaging materials that are non‐biodegradable in nature. Vegetative/food waste is another global issue, evidenced by vastly populated countries such as China and India accounting for 91 and 69 tonnes of food wastage, respectively in 2019. The mitigation of plastic packaging issues has led to key scientific developments, one of which is biodegradable materials. However, there is a way that these two waste‐related issues can be fronted as the analogy of “taking two shots with the same arrow”. The presence of various bio‐compounds such as proteins, cellulose, starch, lipids, and waxes, etc., in food and vegetative waste, creates an opportunity for the development of biodegradable packaging films. Although these flexible packaging films have limitations in terms of mechanical, permeation, and moisture absorption characteristics, they can be fine‐tuned in order to convert the biobased raw material into a realizable packaging product. These strategies could work in replacing petrochemical‐based non‐biodegradable packaging plastics which are used in enormous quantities for various household and commercial packaging applications to combat the ever‐increasing pollution in highly populated countries. This paper presents a systematic review based on modern scientific tools of the literature available with a major emphasis on the past decade and aims to serve as a standard resource for the development of biodegradable packaging films from food/vegetative waste.

“…These are mainly composites filled with various types of fibers, mainly glass fibers (so-called short and long fibers and, in a growing number of applications, continuous fibers). In the literature, many examples can be found of the analysis of the impact of recycling or of the use of recycled materials to obtain new polymer materials [ 4 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ]. The innovative approach in this publication is the analysis of the influence of adding recyclate from pre-consumer waste streams, with the aim of obtaining a mixture of the original polymer with re-granulates and glass fibers not previously subjected to recycling.…”

“…The conducted research allowed for the verification of the properties of the obtained mixtures and newly created materials and the possibility of their reuse. The introduction of short glass fibers into the mixture had a positive effect on the mechanical properties but led to a significant deterioration in the impact strength [ 15 ]. In terms of polymer mixtures and the reuse of various types of polymer materials, research was also conducted by Chiang et al (2020).…”

The problem of the growing amount of waste polymer materials currently affects virtually every area of the global economy. New actions taken by the E.U. and member states could lead to a reduction in the burden on the natural environment, as well as the reuse of thermoplastic waste. The aim of this study was to analyze the possibility of reusing post-industrial waste (recycled polypropylene—rPP) in order to produce mixtures with original polypropylene (PP) and glass fibers. The research undertaken is characterized by a high level of innovation and was carried out on an industrial scale from industrial waste. The primary goal of the analyses was to determine changes in the properties of the polymer mixtures depending on the amount of recycled polymers. For this purpose, four types of mixtures were prepared, characterized by different degrees of filling with recycled material obtained from big-bag packaging (the filling levels were 0 wt.%, 20 wt.%, 30 wt.%, and 70 wt.%). A detailed analysis of the physical properties of the obtained mixtures was carried out to determine changes in the densities depending on the amount of rPP material. In addition, changes in the MFIs (melt flow indexes), characterizing viscosity changes, were analyzed depending on the amount of secondary raw material used. An analysis of the mechanical properties was also carried out based on static tensile testing, the impact strength (the Charpy method), and the Rockwell hardness test (the M method). The analysis of the thermal changes was performed using the DSC method. The results showed that the composites made of virgin polypropylene (PP GF30) and those made from re-granulates and glass fibers (rPP GF30) are characterized by similar mechanical properties and significantly different processing properties, determined by MFI. This means that the addition of re-granulates significantly affects the processability of the obtained materials, while the addition of glass fibers maintains the basic mechanical properties.

“…TPOs recycling in the automotive industry is complex and challenging because of the oxidation of some bumper components, hence the deterioration of the mechanical properties, and the loss of the compatibility at the interphase [3]. Mechanical recycling is the most used method to recycle PP based materials, however, due to the sophisticated morphology of TPOs, the final properties of recycled products often do not meet car bumpers requirements [4,5]. To reproduce original properties, TPOs are often mixed with a virgin polymer and with appropriate fillers and compatibilizers [6].…”

The synthesis of polypropylene-based car bumper waste (PP-CBW)/metallocene linear low-density polyethylene (m-LLDPE)/micro-CaCO3 composite films for agriculture mulch films applications has been thoroughly investigated during this study. The chemical composition of these wastes was determined by Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Three blends of various compositions were prepared using a twin-screw extruder, the pellets were then blown into films using a single screw extruder. The mechanical properties of the films were then studied and compared with the EN 13655, 2002 standards for agriculture mulch films applications. The results indicated that the use of an anhydride grafted polypropylene (MAH-g-PP) as compatibilizer improves the adherence at the interface between the polar acrylic paints present in the car bumper waste and the polymer matrix. Also, the presence of stearic acid surface treated micro-CaCO3 improves considerably the mechanical properties of the composite when the amount of PP-CBW is less than 13 wt%. Using higher amount of PP-CBW improves the tear resistance properties in TD and MD but fails to increase the impact strength and the tensile properties in MD and TD.
