Green Chemistry is an approach to chemistry that aims to maximize efficiency and minimize hazardous effects on human health and the environment. By implementing the 12 Principles of Green Chemistry wherever possible, Sino Lion strives to promote the green chemistry concept in China and globally, leading the green development of the raw material supply chain in the whole industry.

The 12 Principles of Green Chemistry

  • 1.Waste Prevention

    Prioritize the prevention of waste rather than cleaning up and treating waste after it has been created. Plan ahead to minimize waste at every step.

  • 2.Atom economy

    Reduce waste at the molecular lever by maximizing the number of atoms from all reagents that that are incorporated into the final product. Use atom economy to evaluate reaction efficiency.

  • 3.Less hazardous chemical syntheses

    Design chemical reactions and synthetic routes to be as safe as possible. Consider the hazards of all substances handled during the reaction, including waste.

  • 4.Designing safer chemicals

    Minimize toxicity directly by molecular design. Predict and evaluate aspects such as physical properties, toxicity, and environmental fate throughout the design process.

  • 5.Safer solvents & auxiliaries

    Choose the safest solvent available for any given step. Minimize the total amount of solvents and auxiliary substances used as these make up a large percentage of the total waste created.

  • 6.Design for energy efficiency

    Choose the least energy-intensive chemical rout. Avoid heating and cooling, as well as pressurized and vacuum conditions (i.e. ambient temperature & pressure are optimal).

  • 7.Use of renewable feedstocks

    Use chemicals which are made from renewable (i.e. plant-based) sources, rather than other, equivalent chemicals originating from petrochemical sources.

  • 8.Reduce derivatives

    Minimize the use of temporary derivatives such as protecting groups. Avoid derivatives to reduce reaction steps, resources required, and waste created.

  • 9.Catalysis

    Use catalytic instead of stoichiometric reagents in reactions. Choose catalysts to help increase selectivity, minimize, and reduce reaction times and energy demands.

  • 10.Design for degradation

    Design chemicals that degrade and can be discarded easily. Ensure that both chemicals and their degradation products are not toxic, bio-accumulative, or environmentally persistent.

  • 11.Real-time pollution prevention

    Monitor chemical reactions in real-time as they occur to prevent the formation and release of any potentially hazardous and polluting substances.

  • 12.Safer chemistry for accident prevention

    Choose and develop chemical and procedures that are safer and inherently minimize the risk of accident. Know the possible risks and assess them beforehand.
