CHAPTER I INTRODUCTION Pollution is one of the main problems the world faces today. One of the reasons is the overload of non-biodegradable objects like plastics‚ cans and Styrofoam. The invention of plastics and Styrofoam made a huge change in our society and it helped us in many ways. But it is also one of the main pollutants that destroy our planet. Because of these we devised a way to recycle used Styrofoam‚ and this is to make glue out of it. This glue can help reduce the number of Styrofoam
