| | 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. |
