| Abstract | Coffee chaff and eggshells were examined as potential bio-fillers for |
| carbon black due to carbon black’s health risks to the average |
| consumer. Different compounds within the coffee chaff were examined |
| and TGA and FTIR analyses were run on the different components of |
| the coffee chaff and eggshells to compare and contrast physical |
| properties between the compounds. Coffee chaff was also incorporated |
| into a rubber formula in order to examine its effectiveness at replacing |
| carbon black. After the ingredients for each rubber sample were run |
| through the Banbury, plaques were made of each sample and tested |
| for their hardness and thickness values. These values were compared |
| to a control (rubber tire formula without coffee chaff) to examine |
| differences and similarities between coffee chaff and carbon black. |
