Quality Tools Used to Improve Plastic Waste in Construction

The main challenge today is not plastic, viewed from a material perspective, but the transfer from the linear economic model to the circular model in which goods are produced, used and not disposed of but reused. This model starts from the premise of infinite economic growth and does not take into account the fact that natural resources are limited. There are several ways in which construction plastics can be managed during their life cycle and become truly sustainable products. Quality and price are the elements that complicate plastic recycling. Since plastics are easily adapted to the functional or aesthetic needs of each manufacturer, the diversity of the raw material complicates the recycling process, making it expensive and affecting the quality of the final product. While quality assurance refers to the establishment of standards, quality control refers to verifying that the structures or elements comply with these standards and in the field of construction. Achieving quality standards in construction is an intensive process and long-lasting, for which all participants are responsible. Continuous verification that decisions and work meet predetermined quality assurance standards is essential. Among the methods used to improve the quality in the present study, we will only use the Ishikawa diagram, the fishbone diagram and the 5 M's method. The methods were used in Turkey and Romania to identify the causes and factors that can disrupt the management of plastic waste in the field constructions.
