Amid the COVID-19 pandemic, a sudden surge in the production and utilization of disposable, single-use facial masks has been observed. Delinquency in proposal disposal of used facial masks endangers the environment with a new form of non-biodegradable plastic waste that will take hundreds of years to break down. Therefore, there is an urgent need for the resourceful recycling of such waste in an environmentally friendly way. This study presents an efficient solution by using waste masks in fibered or crushed form to produce environmentally friendly and affordable green concrete. This investigation assessed the mechanical and durability properties of waste masks-incorporated concrete. A total of six mixes were prepared for standardized tests to determine compressive strength, split cylinder tensile strength and rapid chloride penetration test (RCPT), and freeze-thaw resistance. The percentage of mask fibers used were 0.5, 1, 1.5, and 2% of concrete by volume, while crushed masks were used at 0.5% only. The mask waste in both forms was found suitable to be used in concrete. One percent of waste mask fibers was found as an optimum value to increase compressive and tensile strength, reduce chloride permeability, and increase freeze-thaw resistance. Besides this, 0.5% crushed mask fiber also performed well, especially for producing less permeable and highly durable concrete. It is thus corroborated that waste masks that increase pollution worldwide can be utilized sustainably to help build green buildings. By reutilizing waste masks to produce improved concrete with better strengths and higher durability, circular economy and sustainability are achieved, along with efficient waste management.

“…In many studies in the literature, polymer composites have been obtained from waste masks by various methods (Mellin vd., 2016;Mohan, Jayanarayanan, & Mini, 2021;Xiang vd., 2021) Recycling masks, which are the most common medical wastes, are important in terms of environmental pollution. There are many polymeric components such as polypropylene in their structure (Joseph, James, Kalarikkal, & Thomas, 2021).…”

In this research, waste masks (WM) that pollute the environment have been evaluated in the polyester composite. Some physical and chemical properties of the obtained composite have been characterized. In particular, its density, Shore D hardness, thermal conductivity, thermal stability, and porosity have been determined. Waste masks were collected, disinfect, ground, dried and added into unsaturated polyester (UP) at the rates of 0 %, 2 %, 5 %, 7 %, and 10 % by mass as a filler. Mask wastes were reinforced to the unsaturated polyester in certain proportions and were homogenized thoroughly for 10 minutes at a mixing speed of 1000 rpm. Then, the chemical reaction has been carried out with the help of methyl ethyl ketone peroxide (MEKP) and cobalt octoate (Co Oc) catalysts. The chemical bond structure of the produced polyester composites was determined by Fourier transform infrared spectrophotometer (FTIR). According to the results, both density and Shore D hardness of the composites decreased as the WM ratios in the composites increased. It has been evaluated that the mechanical strength of the polyester composite and porosity raises with increasing WM ratio. The increase in WM by mass in the polyester composite raises thermal conductivity and activation energy.
