Scientists in China have developed a tough new bamboo-based plastic that biodegrades in 50 days. The new material matches the strength of engineering plastics used in cars and appliances while retaining 90% of its durability after recycling. Researchers say bamboo’s rapid growth makes it a promising, renewable alternative to oil-based plastics.
