Microplastic pollution is a problem that threatens not just marine ecosystem, but also human health (Sharma & Chatterjee, 2017). Approximately 0.1 milligrams of microplastic particles are released by each gram of synthetic textile in each washing cycle (Hernandez, Nowack, & Mitrano, 2017). With this in mind, we investigated potential mitigation methods in reducing the concentration of microplastics in laundry discharge. We start by identifying potential factors that contribute to amount of microplastics in laundry discharge, namely type of laundry detergent and the “wear and tear” factor. Our experimental results verified the presence of plastic microfibers released by RVRC launderettes during washing of synthetic textiles. We hypothesised that using liquid detergent will cause less microplastic shedding compared to powder detergents and older clothes will shed more microplastic as time progresses. Hence, we propose using liquid detergents for laundry and wash synthetic clothings with the appropriate washing guideline to improve their longevity.
