Method used to control pollution:

Installation of gobar gas plant:


  • Installation of gobar gas plant is an effective method to control pollution.

  • Gobar gas plants use organic waste such as cow dung to produce biogas for cooking and electricity generation.

  • By using cow dung as a renewable energy source, gobar gas plants reduce the dependency on fossil fuels like coal and petrol.

  • This helps in reducing air pollution and greenhouse gas emissions.


Dumping of non-biodegradable waste in low-lying areas:


  • Dumping of non-biodegradable waste in low-lying areas is not a method used to control pollution.

  • It is an improper waste disposal method that can lead to environmental pollution and degradation.

  • Non-biodegradable waste should be properly segregated, recycled, or disposed of in designated landfill sites.


Use of coal and petrol:


  • The use of coal and petrol is not a method used to control pollution.

  • Coal combustion releases harmful pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter, contributing to air pollution and climate change.

  • Petrol combustion in vehicles also emits pollutants such as carbon monoxide, nitrogen oxides, and volatile organic compounds, which are harmful to human health and the environment.


Conversion of organic waste and fecal material into compost:


  • Conversion of organic waste and fecal material into compost is an effective method to control pollution.

  • Composting is a natural process that transforms organic waste into nutrient-rich compost, which can be used as a soil conditioner.

  • This reduces the amount of organic waste going to landfills, preventing the release of methane, a potent greenhouse gas.

  • Composting also improves soil health, reduces the need for chemical fertilizers, and promotes sustainable agriculture.


Therefore, the correct answer is option C: (a) and (d) are correct. The installation of gobar gas plants and the conversion of organic waste and fecal material into compost are methods used to control pollution.
