Kozdrach and Radulski , in their research published in Scientific Reports, investigated the potential of using biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More derived from chokeberry as a sustainable additive in vegetable oil-based lubricants. The researchers focused on the tribological and rheological properties of the lubricants, analyzing the impact of biochar produced at different pyrolysisPyrolysis is a thermochemical process that converts waste biomass into bio-char, bio-oil, and pyro-gas. It offers significant advantages in waste valorization, turning low-value materials into economically valuable resources. Its versatility allows for tailored products based on operational conditions, presenting itself as a cost-effective and efficient More temperatures and concentrations . Their findings suggest that chokeberry-derived biochar can significantly enhance the performance and sustainability of lubricants.  

The increasing demand for environmentally friendly lubricants has driven research into bio-based additives. Chokeberry, a fruit rich in antioxidants and minerals, presents a promising source for biochar production. The study found that incorporating chokeberry biochar into rapeseed oil-based greases led to improved tribological properties, including enhanced anti-wear and anti-scuffing characteristics. The biochar also positively influenced the rheological behavior of the lubricants, affecting their flow curves, viscosity profiles, and viscoelastic characteristics.  

These improvements are attributed to the unique properties of chokeberry biochar, which include high porosityPorosity of biochar is a key factor in its effectiveness as a soil amendment and its ability to retain water and nutrients. Biochar’s porosity is influenced by feedstock type and pyrolysis temperature, and it plays a crucial role in microbial activity and overall soil health. Biochar More, surface area, and the presence of beneficial compounds inherited from the fruit. The study highlights the potential of chokeberry biochar as a sustainable alternative to conventional lubricant additives, contributing to the development of greener and more efficient lubricants.
