Abstract

Abstract The textile sector has been an important part of Bangladesh’s (BD) economy over the past few decades. In Bangladesh, the textile sector currently has an export value of nearly 28 billion USD per year which contributes about 82% of the country’s total export earnings. It is projected that the annual ready-made garment (RMG) export value will be about 50 billion USD per year by 2021. However, the growth of Bangladeshi RMG sector is associated with different environmental issues, mostly caused by wastewater generated by textile industries. Textile industries consume high volumes of water per unit fabric for processing, which cause depletion of ground water levels at a high rate. In addition, in many cases textile effluents are discharged into rivers or wetlands without proper treatment. Untreated textile effluent can contaminate groundwater and waterbodies, reduce dissolved oxygen in water and affect aquatic ecosystems which may indirectly cause climate change. Improving conventional technology, adopting cleaner production (CP) options, the reusing and recycling of treated water may reduce water consumption, effluent volume and water stresses, and may help preserving aquatic ecosystems. However, additional investments, lack of technological knowhow, and awareness are factors limiting the adoption of cleaner production options. In order to take effective measures for future improvement it is important to develop a nationwide wastewater impact tracking system. In this study, a material balance approach has been developed to characterize the trend of pollution impacts (2011–2021) associated with the textile dyeing industries of Bangladesh. It is estimated that in 2016 textile industries in Bangladesh produced about 1.80 million metric tons of fabric, which generated around 217 million m3 of wastewater (2016) containing a wide range of pollutants. It is projected that wastewater production will reach 349 million m3 by 2021 if the textile industries continue using conventional dyeing practices. Gradual adoption of improved technology and cleaner production options could reduce wastewater volume by around 23% by 2021. This projection will help policy makers to take necessary mitigation measures for treatment and pollution management. This analysis will also provide a baseline scenario and open new opportunities for textile engineers and environmentalists to develop innovative technologies for textile dyeing and effluent treatment.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
