The plastic manufacturing industry is a large and intricate sector that produces a variety of plastic products used in numerous industries, including packaging, construction, automotive, and healthcare, among others. Various processes, including injection moulding, extrusion, and blast moulding, are utilised to create a variety of products from synthetic or semi-synthetic materials. Population growth, urbanisation, and consumer preferences for convenience and durability continue to drive an increase in the global demand for plastic goods. However, environmental concerns, such as the dispersal of plastic waste and the use of non-renewable resources, present obstacles for the industry. Consequently, there is a growing interest in sustainable solutions and circular economy models that seek to reduce the environmental impact of plastic production.
