i hit on the idea of using coffee grounds as a raw material while studying in italy for three years he worked on getting the correct composition there was no shortage of the basic ingredient coffee grounds usually end up in the trash after brewing. if you dried careful you get a very fine powder from it which is make a good replacement for different fibers and can be added. yeah stretch. polymers to a very solid new material. the recycled cups are pressed into shape by a cologne company the grounds are mixed with wood and cellulose which preserves and stabilizes them the cups are also good for the environment when decomposing organic waste produces harmful greenhouse gases so recycling the coffee grounds is beneficial for the climate. yes.
