A great attention, from environmental point of view, has been directed toward reducing fossil fuel consumption and finding alternate, renewable sources of materials in the rubber industry. The dominant filler for rubber composites is carbon black (CB), the petroleum product, due to its exceptional reinforcement properties, purity and low cost. Recently, the major interest is made in replacement of CB with biochar because of its renewability and low cost. In order to compare CB and biochar impact on the power consumption of rubber mixer, two experiments were conducted: standard CB and the biochar made from woody waste feedstock were blended as filler with natural rubber commercial mixture. The experiments were conducted with 0, 10, 20, 30, 40 and 50 phr of CB and biochar. Power consumption of rubber mixer was the similar (around 44 Wh) for both mixtures with 0, 10 and 20 phr, and then started to increase using the CB, compared to biochar. Natural rubber blend with 50 phr of CB made a power consumption of 51 Wh, while the same share of biochar made 48 Wh. In addition to all its advantages, using biochar can contribute towards reducing energy consumption.
