Abstract
This project compares a soy ink formulation to a petroleum ink formulation for their advantages and disadvantages. This was accomplished by evaluating the rejected samples from the flotation cell deinker. These samples were degraded aerobically and anaerobically to determine the rate at which degradation takes place and the ultimate degradation over a specific time interval. This was done by finding the biochemical oxygen demand (BOD). The data from these tests was put into a spreadsheet and data processing program to find the rate of degradation and ultimate degradation. From this, the two methods of degradation were compared along with the two ink formulations and their effect on the environment. Possibly due to the affect of curing time and fiber content, the comparison of soy and petroleum inks was inconclusive until further research can be done in these areas.
