(iii) Dairy industry- Dairy processing plants should be designed, built and operated to achieve:

• maximum recovery of products such as milk fat and solids.
• minimization of losses or emissions to the environment.
• recycling and/or reuse of wastes.
• prevention of further environmental degradation.
• restoration of the environment.
• appropriate location of the plant to minimize the impact on residents, while still allowing for future expansion.
• waste management, to avoid degradation of the community environment.

Cement industry : There are a number of environmental issues related to the cement sector, such as control of air pollutants (dust and gaseous emissions), reduction of greenhouse gases (GHG), the control of fugitive dust, utilization of hazardous wastes as alternate fuels and the conservation of natural resources. The Indian cement industry has shown phenomenal performance in terms of improving air quality. Dust emissions are reduced and cement plants conform to the environmental parameters set by statutory bodies.
