Evaluated Alternative Nano Cellulose + PLA Composite Material The plastic pollution is getting severe in the world and especially microplastic problem in the marine environment. There is some scientific evidence that these microplastics are already in our human body, which comes from our surrounding environment. Therefore, plastic recycling, reduction of plastic usage itself and biodegradable plastic usage and development, have been intensively attempted and carried out. Green Science Alliance a new bio-based plastic material by mixing PLA with Nano cellulose. The material is derived from 100% natural sources and contains no petroleum. By mixing PLA with Nano cellulos, PLA becomes mechanically stronger and biodegradability accelerates. It also increases crystallinity and foaming property.
