   Abstract: 
   The scarcity of fresh drinking water has become a major concern in various parts of the world recently. Therefore, this study aimed to develop a sustainable polymer (polypropylene) and carbon (activated carbon from coconut shell) based water treatment filter. The filter was made by integrating polypropylene nonwoven fabric on top of a two-inch layer of activated carbon and the traditional slow sand filter. The filter showed a significant reduction in turbidity, total dissolved solids (TDS), biological oxygen demand (BOD), pH, and concentration of heavy metals (HM) in the water samples collected from Turag River, Bangladesh. The reduction efficiencies were more than 85%. The higher value of reducing heavy metals, TDS, BOD, and pH might be explained by higher particle retention and adsorption capacity of the filter due to the notable higher specific surface area of activated carbon and the pore size of the polypropylene filtration layer. The concentrations of lead, zinc, iron, potassium, magnesium, calcium, and copper were examined in which the filter showed a promising result; however, the removal efficiency of other potential heavy metals is yet to be tested.

2. Uddin, M., Ullah, M. R., & Dipto, M. R. R. Assessment of the current working condition of the garment workers and determining the importance of labor union for the improvement of working condition in the RMG industry of Bangladesh.
   Abstract: 
   The well-being of the workers is one of the most important issues in industries worldwide. The ready-made garment (RMG) industry of Bangladesh is the backbone of the country's economy which has been facing challenges to ensure workplace safety of the workers. Also, there has not been a healthy growth of labor unionism within the RMG industry. Previous studies suggest that there is a widespread occupational segregation and gender discrimination in wage rates. The purpose of this study is to assess the current working condition of the garment workers in terms of health and workplace safety and gender discrimination. Another purpose is to determine the impact of labor union on improvement of the workers' condition. The study uses survey data from 203 responses to evaluate the working condition of the RMG industry. An exploratory data analysis was done to measure the occupational health and safety which was followed by a logistic regression to find out the relation between labor union and other variables. Results reveal that gender discrimination has been reduced greatly, fire, building and other workplace safety measures has been consistently improving and labor union has a significant impact on enhancement of betterment of the workers.

3. Uddin, M., Tushar, S. I., & Sakib, S. (2020). Producing Sanitary pads from knitwear waste in Bangladesh. Materials Circular Economy, 2(1), 15. 
   Abstract:
   At present, not only Bangladesh but also the entire world is so conscious about women’s health and environmental protection. In our country, a large number of women, especially those from low socio-economic groups, do not use sanitary napkins since the available pads in the market are costly. They make use of old rags instead which are not comfortable or hygienic, leading to illnesses which constantly cause absence from work. On the contrary, export income of Bangladesh heavily depends on its textile industry which produces almost 500,000 tons of clothing waste annually. Moreover, clothes are generally thrown away after use. Both these incidents cause serious problems to the environment. For instance, waste clothes take plenty of time to mix with soil, causing landfill problems. Besides, some people burn these thrown away clothing materials in order to reduce solid waste, which instead causes carbon emission. Burning these wastes is not a solution. To solve these problems we have made sanitary pads from recycled cotton collected from waste clothes and thrown away clothing materials, particularly the knitwear which are more sustainable, lightweight, and affordable.
