ABSTRACT

The textile industry is one of the most critical sectors in Bangladesh, for it depends on the textile industry heavily, which accounts for a considerable portion of its exports and annual GDP. The low cost of the labor force becomes a decisive advantage that attracts Western countries to open factories there, especially around Dhaka areas. However, while earning a profit, Bangladeshi textile industries emit a huge amount of pollutions, devastating the local environment severely. This research paper reveals the value of several discharged wastewater pollution- Biochemical oxygen (BOD), Chemical oxygen demand (COD), Dissolved oxygen (DO), and pH value from the Bangladesh Bureau of Statistics (BBS)- around the blue river's garment factories to find the causes of pollution and evaluate river water quality. The results display that the total amount of water pollution already goes beyond the standard level, meaning that the Bangladesh government should consider the detrimental impact the Bangladesh textile factories cost seriously. Our research paper summarizes several efficacious strategies such as adopting waterless dyeing technology, Pigouvian tax, cap and trade, and more rigorous environmental regulation, thereby enabling Bangladesh to minimize its textile industry's pollutants while developing its economy.
