Processing techniques on plastic waste materials for construction and building applications

Abstract

Plastic trash has become a huge environmental concern due to the large volumes produced, inflicting substantial harm to both the ecology and its inhabitants. This hazard has a huge impact on the maritime environment. The plastic garbage produced on land eventually makes its way to water bodies, where it has negative consequences such as floods and marine animal poisoning. When aquatic animals like fish consume this plastic garbage, it is detrimental to human health as well. To determine the most efficient method for managing these wastes and enhancing the sustainability of our ecosystem, this review discloses several processing strategies for recycling plastic trash into new goods with a specific focus on construction and building. It has been discovered that recycling plastic trash for building purposes would significantly improve climate sustainability along with serving as a reliable source material in construction supplies. This study shows that employing recycled plastic waste, as a component in cementitious composites is the most advantageous because it may be used to replace all of the composite's solid components. The pursued qualitative analysis of various plastic waste management techniques, focusing on the most significant features, reveals that newer methodologies are more effective in terms of environment and sustainability, but are not economical. Finally, limitations and directions of use are also listed to throw light on the recycling of circular economy.
