ReOil is a sustainable energy company that transforms waste sunflower oil into biodiesel. We developed a bold and clean visual identity reflecting both the ecological mission and industrial reliability of the brand. The logo combines a stylized oil drop with recycling arrows to symbolize the closed-loop process. We designed a cohesive visual system including color palette, typography, and branded assets – from vehicle graphics and worker uniforms to oil canister labels and product stickers. The bright yellow and deep navy color scheme enhances visibility and memorability, while supporting the brand’s eco-tech positioning.
