Abstract: In oil spill clean-up, a sorbent is material that is used to absorb oil and repel water. Sorbents are used very frequently, but many of them tend to be expensive or inefficient. Based on extensive research, it is found that a combination of polypropylene, polyester, reclaimed newspaper print, and vermiculite makes a very effective filler for a sorbent. It is concluded after many trials that a composition of 48.63% polypropylene, 27.97% polyester, 12.53% newspaper print, and 10.87% vermiculite in a sorbent absorbs the most oil and repels the most water. A non-provisional utility patent will protect this ratio and introduce a competitive, cost-effective, and eco-friendly sorbent into the market.
