Summary

This review paper looks at how plastic waste (like bottles) can be turned into building materials and architectural walls instead of ending up in landfills or oceans—and it's up to 30% cheaper than traditional construction materials. This matters for your health because less plastic waste sitting around outdoors means less breaking down into microplastics that can contaminate our water, food, and air; however, more research is needed to confirm these building materials are safe and durable over time, since plastics can still shed tiny particles as they age.

The increase in environmental pollution due to the accumulation of huge amounts of plastic waste led to the generation of a new technique, the circular economy, which emphasizes the reuse, recycling, and regeneration of materials. This paper discusses the innovative application of plastic waste as a construction material, aiming to reduce environmental impact and promote sustainable building practices. By incorporating plastic waste into construction materials, the potential benefits and challenges include its structural properties, durability, thermal performance, and aesthetic versatility. Case studies of existing projects utilizing plastic waste in architectural applications are analyzed to demonstrate the feasibility and effectiveness of this approach. The findings highlight how plastic waste can be transformed into valuable resources, contributing to the circular economy and offering practical solutions for sustainable architecture. Building with plastic bottles can be up to 30% cheaper than conventional materials. This study provides a comprehensive overview of the techniques, materials, and design strategies involved in integrating plastic waste into building facades, paving the way for future innovations in sustainable construction.
