40 Inventive principles are different processes of mitigating pollution, and this invention was propounded by a Russian Scientist Genrich Altshuler,

The principles include:

• Segmentation: Divide the system into smaller parts to reduce the amount of pollution generated.
• Taking out: Remove the source of pollution from the system.
• Local quality: Change the properties of the system to adapt to the local environment and reduce pollution.
• Asymmetry: Introduce asymmetry into the system to reduce pollution.
• Merging: Combine similar systems to reduce the amount of pollution generated.
• Universality: Use a single system to perform multiple functions, reducing the need for additional components and reducing pollution.
• Nesting: Place one system inside another to reduce the amount of pollution generated...
