🌱 Hemp waste makes eco-packaging way stronger
Korean researchers successfully strengthened biodegradable plastics by using hemp hurd, an agricultural byproduct. The team from KRICT developed this method using industrial hemp stalks in Andong, Gyeongsangbuk-do. The process achieved a 26.2% increase in tensile strength when incorporating the filler into TPS/PBAT films. This technique cleverly controls moisture and uses a low-cost chemical agent to prevent fiber clumping during drying. The technology could soon be applied to soybean stalks and rice straw, aiming to reduce waste and costs. ♻️
