The use of plastic has grown extensively in recent years all over the world. It is inexpensive and easily available and can be moulded into any shape. However, plastic is nonbiodegradable; it causes pollution and create difficulties in managing even for a wealthy nation. The purpose of this study was to investigate the environment-friendly potential use of plastic and demonstrate usefulness of plastic sand bricks as alternative structural elements, replacing standard clay brick. The physical and mechanical properties of plastic sand bricks were studied in different plastic sand ratios of 1 : 3, 1 : 4, and 1 : 5 by their weight, using plastic as a binder. Moreover, the thermal resistance test, split tensile strength test, penetration test, and Fourier transform infrared spectroscopy were performed. The study concluded that the strength of plastic sand brick depends upon the uniformity of the mixture and increases when the ratio of sand and plastic in the mixture is increased to 1 : 4 from 1 : 3. Any increase or decrease in the ratio 1 : 4 is found to reduce the strength. All the bricks in any of the ratios showed zero water absorption and nil efflorescence.

“…Recycled aggregates from ceramic waste, on the other hand, have lower mechanical resistance than recycled concrete aggregates [22], which has a negative impact on the performance of masonry mortars made from this type of sand. Among the most important characteristics of mortars made with ceramic recycled aggregate are their excessive porosity and demand for kneading water [23], their high shrinkage values and their high fine content generated during their manufacture [24], their lightness [25] and its reduced durability in salt crystallization cycles [26].…”

The construction sector is one of the main consumers of raw materials and generates a high volume of waste within the European Union. The search for new materials that are more sustainable and respectful of the environment has become a challenge for countries with a high degree of industrialization. In this work, a study of the most relevant properties of masonry mortars made with recycled aggregates and reinforced with synthetic fibers was carried out. Three types of aggregates were used—natural, concrete recycling and ceramic recycling—and two types of reinforcing fibers: polypropylene and polyolefin. In this way, various tests of physical-mechanical characterization and a statistical analysis of the results were carried out. It has been shown that the mortars made from aggregate recycled concrete and reinforced with polypropylene fiber are the ones with the best properties for application in the construction sector, although without improving the properties of traditional mortars made from natural aggregate and without fibers.

“…The composition of cement, eggshells, and glass is the same. Therefore, the glass and eggshell powder can replace the cement content in the brick [24]. The sand and cement have the same chemical composition; therefore, there is no need to add cement in poly sand bricks as a binder.…”

With continuous progress in science and technology, we are facing more problems too. One of the biggest problems is the allocation or decomposition of materials when they come to their end i.e., the waste materials. In this study, we employed plastics and glass waste, as well as organic wastes, and eggshells, to test the influence of casting and melting procedures on ordinary concrete bricks in this research. As per the results, the density of the brick reduces to ~20% when the cement is replaced with 10% EggShell Powder (ESP) and 20% Glass Powder (GP) and 86% when replaced with 25% plastic in the sand (PolySand Bricks), whereas the durability of all the compositions came under the heavy load-bearing bricks category (~6%). Furthermore, the 10% ESP-based bricks show the maximum compressive strength (~18%), whereas the 25% Plastic replaced PolySand bricks showed (~9%) strength, which makes them suitable for use in pavements.
