Smart production and photocatalytic ultraviolet (PUV) wastewater treatment effect on a textile supply chain management

Abstract

Wastewater from a garment production system in a textile supply chain management is one of the main sources of water pollution. Wastewater is still an increasing problem for medium to large production industries as traditional wastewater treatments are not much effective, especially for removal of contaminated organic particles and heavy metals. Photocatalytic ultraviolet process is an eco-friendly and promising wastewater treatment since the last one decade with the removal of organic particles. This study examines a textile supply chain management, which uses the photocatalytic ultraviolet process for the wastewater treatment from the production system. The production system plays an important part to exclude wastewater from the system. The unnecessary production run-time not only produces excess garments but also produces excess wastewater, which is blended with dyestuff extracts. A smart production is able to control the garment production based on the necessity and the control of wastewater generation is possible. Despite of the amount of wastewater, the treatment of wastewater gradually becomes a part of the textile supply chain with economic valuation. The textile supply chain management is built by multi-supplier and multi-manufacture, where the garment production is controlled by a smart production system. The manufacturers provide a photocatalytic ultraviolet wastewater treatment and this wastewater treatment positively effects the market demand of garments. The global optimum solutions of the study prove that the use of smart production reduces the cost of the textile supply chain 18.55% followed by the PUV wastewater treatment 16.01%. The results reveal that an involvement of categorized labor for material handling in a textile supply chain management is cost effective rather than using uncategorized labor. Skilled labors are found to be the most sensitive for a textile supply chain management.
