Innovative Biodegradable Sponge for Microplastic Filtration

Researchers in China have developed a biodegradable sponge crafted from squid bones and cotton to combat the pervasive issue of microplastics in water sources. This innovative material, known as CT cell, utilizes the natural properties of chitin found in squid bones and cellulose from cotton, creating a highly effective filter. Initial tests have shown that it can remove between 98% to 99.9% of microplastics, such as polystyrene and PET, from different water sources, including irrigation and seawater. Unlike conventional plastic filters that contribute to pollution, this sponge decomposes into harmless byproducts, presenting a sustainable solution to an escalating environmental crisis.
