Abstract
The urbanization process contributes to the growth of solid waste generation and causes an increase in environmental impacts and failures in the management of solid waste. The number of dumps is a concern due to the limited implementation and safe disposal of this waste. The interest in sustainable techniques has been growing in relation to waste management, which is largely absorbed by the civil construction sector. This work aimed to review plastic waste, especially polyethylene terephthalate (PET), that can be incorporated with construction materials, such as concrete, mortars, asphalt mixtures, and paving. The use of life-cycle assessment (LCA) is related, as a tool that allows the sustainability of products and processes to be enhanced in the long term. After analyzing the recent literature, it was identified that studies related to plastic wastes in construction materials concentrate sustainability around the alternative destination of waste. Since the plastic waste from different production chains are obtained, it was possible to affirm the need for a broader assessment, such as the LCA, providing greater quantification of data making the alternative processes and products more sustainable. The study contributes to enhance sustainability in alternative building materials through LCA.
Highlights
The global urbanization process is one of the main factors responsible for the substantial growth in the generation of solid wastes, demanding attention for the increase in environmental impacts caused by the accumulation and failures in the management of solid wastes
The addition of polyethylene terephthalate (PET) decreased the values of the resilience module of construction and demolition (C&D) waste, while with crushed bricks they presented higher values of resilience module than with recycled concrete
The mixtures stabilized with cement containing 5% PET with C&D residues presented physical and mechanical properties that meet the technical requirements for the construction of the base and sub-base of pavement
Summary
The global urbanization process is one of the main factors responsible for the substantial growth in the generation of solid wastes, demanding attention for the increase in environmental impacts caused by the accumulation and failures in the management of solid wastes. Developing countries do not have a standard with regard to waste management practices and this fact contributes to the application of informal process models and, favors irregular disposal, such as in open dumps [1]. The world generates 2.01 billion tons of solid urban waste per year, at least. For example, uses waste management, where almost 44 million tons of waste are generated annually, only 1% is disposed in dumps, with the rest being recycled or converted into energy in state-of-the-art facilities [4]
