Lauren Gropper is tackling the problem of single-use plastic waste by replacing petroleum based plastics with plastic made from plants. Repurpose's products range from disposable plates and cups to garbage bags and straws -- all of which are made entirely from plants using upcycled materials such as eucalyptus, sugarcane pulp, and wood. They are totally non-toxic and fully degradable. Lauren aims to make Repurpose the go-to for disposable tableware in general, taking down brands like Solo and Hefty which are responsible for huge amounts of plastic pollution.
