“…Furthermore, the outcomes demonstrate that all treatments enhanced the cement mortar's qualities as compared to polyethylene that had not been treated. (5) However, compared with a mix without plastic, (6) it reduced compressive strength and bond while increasing tensile strength. (6) Jain et al (7) employed the trash from plastic bags in concrete to address the issue of rising waste and to create high-quality, inexpensive concrete that is advantageous to both building construction and plastic recycling.…”

The goal of this work is to reuse plastic waste as a result of the production of valves on gas bottles into concrete. In this way, one can reduce and consume that waste and at the same time reuse it in concrete and study its effects on its properties to decide which best content. This kind of plastic waste was used in different quantities (5%, 7.5%, 10%, 12.5%, and 15%) to replace fine natural aggregate (sand) partially. The effects of these ratios on the fresh concrete's slump factor, the density of hardened concrete, compressive strength, absorption, microstructure, and ultrasonic pulse speed were studied and compared with a reference mixture free of plastic waste. The ANOVA analysis was used to analyze the results of the fresh and hardened tests, and it was concluded that 5% was the ideal percentage of the percentages used, as it had less negative influence on the properties of concrete. From laboratory work, it was concluded that increasing the percentage of plastic waste has a negative impact on the properties of concrete, such as reducing compressive strength, flexural strength, spitting tensile strength, and increasing absorption.

This research aims to create green concrete with acceptable characteristics by recycling glass and plastic waste together. Cement was partially replaced with a 15% waste glass powder by weight mixture and fine aggregates with a 5% waste plastic crushed mixture. According to the findings, adding glass alone to concrete enhanced its qualities, such as compressive strength, splitting tensile strength, flexural strength, energy capacity, and bond strength, compared to a reference sample. The splitting tensile strength increases with replaced cement by 15% glass by 5.4%. When replacing fine aggregate with 5% fine plastic, splitting strength decreases by 5.4%. Flexural strength increased by 1.6% when adding 15% glass to the reference mixture. On the other hand, replacing sand with plastic for concrete with 15% glass powder led to some properties of concrete being affected downwards.

“…Reusing these waste resources in concrete has the effect of reducing the cost of treating waste resources, protecting the environment from pollution, and has many advantages, such as improving some properties of concrete [1]. Therefore, research on eco-friendly concrete technology using waste resources is being actively conducted to prevent environmental pollution and reduce carbon emissions.…”

Currently, membrane filters, which need to be replaced regularly as they get worn, are used in filtration facilities globally. The old membrane filters and housings become continuous industrial waste and are currently 100% incinerated. To solve this environmental problem, this study proposes the development of an eco-friendly concrete by mixing waste membrane resources with concrete. Through this, the environmental pollution and wastage of resources due to incineration, and the enormous amount of carbon dioxide generated during cement production, can be decreased by reducing the cement required when mixing concrete. To this end, the membrane module outer surface (acrylic butadiene styrene, ABS) and inner membrane (poly vinylidene fluoride, PVDF) were extracted from the waste membrane system and pulverized. Different mix ratios of 1%, 3%, and 5% for replacing cement were used when mixing concrete. The test specimens were then tested and compared with the reference concrete (ordinary Portland cement) specimen. It was confirmed that the compressive strength was high after 28 days in all the specimens to which ABS was added at 1%, 3%, and 5% mix ratios. Therefore, the possibility of technological development of eco-friendly concrete using waste resources from membrane filtration facilities was verified.
