Los Angeles - based start - up But an LA-based start-up is looking to solve the dairy waste problem by putting excess milk to good use. Mi Terro has introduced a t - shirt manufactured using milk which would otherwise be discarded . The company has been working with a manufacturer in Germany to up - process the milk into a fabric which can be used to produce a t - shirt , a process which takes roughly two months . The process involves removing fat , water and unwanted proteins from the milk , resulting in fibres which can be spun out into a yarn . Dairy waste is estimated to account for 20 % of waste in US incinerators and farms , according to the US Department of Agriculture .
