Starting with the discovery of fire and the preparation of food in prehistoric times, mechanochemistry is the oldest form of chemistry that humans have controlled.Mechanochemical practices, such as grinding with a mortar and pestle, continued into the Middle Ages until dedicated scientific studies began in the 19 th century.Since then, research in mechanochemistry has shown that many chemical reactions can be performed via mechanical force without or with small amounts of solvent.Besides being time, material, and energy efficient, mechanochemical reactions often yield products that differ from those obtained in solution.Therefore, not only is mechanochemistry greener and more sustainable than conventional solution chemistry, but it also has the added value of providing new reactivity and selectivity.This is especially important today, when chemists need to invent high-performance materials, intermediates, and products with the use of sustainable feedstocks and develop environmental remediation pathways.At the same time, time-resolved in situ monitoring and computational modeling are necessary for addressing fundamental questions about the atomistic, molecular, and electronic nature of mechanochemical reactivity.Integrating digitalization, robotics, and artificial intelligence tools promises to increase the reproducibility and scalability of mechanochemical processes.Further evolution of mechanochemistry is expected to have a transformative effect on the chemical industry.
