The Smilepack egg cartons are made with fiber recovered from recycled paper, which can be reused up to seven times. The cartons can be recycled in regular paper stream and they are home and industrially compostable. Smilepack is already in use in the U.S. by a prominent producer and distributor of free-range eggs, whose products are sold in retail stores across the country. It is estimated that by switching to fiber packaging, this company will eliminate around 4.6 million plastic egg cartons, or around 200 metric tons of plastic annually.
