It is estimated that the equivalent of 50 billion plastic bottles’ worth of microplastics enter wastewater every year from washing synthetic garments. There’s no single solution to tackling fashion’s impact on the planet but we do know that wool fabrics - even those treated with Hercosett resin to be machine washable - are biodegradable in marine environments. This means that 100% wool fabrics do not contribute to microplastic pollution.
