“…28 Monoclinic, trigonal, and orthorhombic forms are among the crystal modifications found in semi-crystalline iPP structures. 29 Despite the fact that polypropylene is one of the most widely used plastic packaging components, only around 1% of it is reprocessed, meaning the majority of it ends up in landfills 30 These take 20-30 years to disintegrate. Apart from the harmful chemicals in PP like lead and cadmium, this poses serious environmental concerns.…”

“…Companies have done “life cycle” studies to determine how recyclable polypropylene is, which examine at the plastic from production stages to the last phase of waste disposal to determine the materials long‐term viability. According to the findings of these investigations, PP has a lot of potential as a long‐term product 30 . Extrusion of fibers, hot drawing, hot stabilization, and fiber indentation are all steps in the manufacturing process 27 …”

The scientific community is currently confronted with critical problems in providing a healthy world for future generations. The study for sustainable plastic recycling methods is difficult for a variety of purposes. Indeed, during the previous century, the widespread usage of plastic materials has resulted in vast amounts of long‐lasting waste that has remained largely unaddressed by effective collection and disposal policies. Packaging materials are responsible for the majority of this waste which also includes polypropylene materials. However, environmental concerns imposed a new trend in the previous decade that brought this research under focus, as seen by the growing number of linked publications. For the recycling of polymeric plastic materials, several chemical and mechanical methodologies have been proposed. Due to the low ultimate tensile strain of concrete, plastic waste fiber materials have been used in concrete in recent times as the reinforced concrete components often function with cracks during the serviceability phase. The bonding strength and stress variation during flexure, toughening effect of a hybrid combination of steel and recycled polypropylene fibers on high‐strength concrete are investigated. Polypropylene's compressive and tensile strength, good dielectric characteristics, and acid and alkali resistance have all been observed in various studies. Hence the current review focus on the past researches on utilization of recycled polypropylene in concrete for the enhancement of its physical and mechanical properties.

“…The employment of both types of fibers in the same inorganic matrix enhanced the compressive strength concerning geopolymers reinforced using only organic fibers. Ramos et al used polypropylene to develop new sustainable functionalized composite materials as well [ 57 ]. In particular, their study concerned the enhancement of geopolymer concrete waste by functionalizing this inorganic matrix with polypropylene and vinyl trimethoxysilane.…”

In the last decades, new synthetic hybrid materials, with an inorganic and organic nature, have been developed to promote their application as protective coatings and/or structural consolidants for several substrates in the construction industry and cultural heritage field. In this context, the scientific community paid attention to geopolymers and their new hybrid functional derivatives to design and develop innovative and sustainable composites with better chemical resistance, durability and mechanical characteristics. This review offers an overview of the latest progress in geopolymer-based hybrid nanofunctional materials and their use to treat and restore cultural heritage, as well as their employment in the building and architectural engineering field. In addition, it discusses the influence of some parameters, such as the chemical and physical characteristics of the substrates, the dosage of the alkaline activator, and the curing treatment, which affect their synthesis and performance.
