20 Jul Paper sunflower seeds’ shells ( P3S )

World consumption of paper has grown 400% in the last 40 years. Now nearly 35% of the total trees cut around the world are used in paper industries, which is a disaster for nature. As wood contains 40-50% of cellulose, and sunflower seeds’ shell contain 48% of this material as well, which is the main component of paper making, we found out that we can reduce the use of trees by replacing it by sunflowers seeds’ shell. First we soaked sunflower’s seed shells in water for 6 hours to make it more easy to use . Second we boiled them and add them sodium carbonate for 30 minutes on high temperature. Then we kept pounding it to produce pulp. Finally we dried it on a hot surface.
