Abstract
One of the significant problems of our time and future is environmental pollution. There are many factors that cause environmental pollution and the main concerns are waste material. Since production, consumption and service activities have increased with rapid industrialization and increasing population. Waste assessment is a process that includes minimization, separate collection at source, intermediate storage, pre-treatment, the establishment of waste transfer centers, recovery and disposal when necessary, which are qualified as outputs as a result of activities such as production, application and consumption. The purpose of waste assessment is to ensure the process of wastes generated by human action without harming the environment and human health. In this context, re-evaluation of agricultural and aquaculture products that turn into waste after being used as a product is important both in terms of economic and environmental pollution. Herein, the use of cumin black pulp, which is waste at the end of black seed oil production, as a bio-based filler material in ethylene-propylene diene rubber (EPDM) was examined. Accordingly, the effects of cumin black pulp added to the EPDM matrix at different content on the rheological, mechanical and crosslinking degree of EPDM were determined. With the use of 10 phr cumin black pulp, the mechanical and rheological properties of EPDM and the degree of crosslinking increased. The tensile strength and elongation at break of the EPDM/CB composites increased up to 11 MPa and 480% with the addition of 10 phr CB, respectively. In addition, it was revealed that the vulcanization parameters were also enhanced. Consequently, it has been concluded as a result of the analysis that the waste cumin black pulp can be used as a filling material in the EPDM matrix. Thus, it has been seen that a product in the state of waste can be recovered and become an economic value.
