Biogas - GS questions based on daily current affairs

1)   Which of the following are the benefits/uses of biogas?

1) Bio-manure is obtained
2) Improves sanitation in village
3) Reduce causes of climate change

a. 1
b. 2, 3
c. 1, 3
d. All of the above
Answer  Explanation 

ANSWER: All of the above

Explanation:
The process of biogas generation is called anaerobic digestion (AD) and salient benefits of biogas technology are -

  • It provides clean gaseous fuel for cooking and lighting.
  • Digested slurry from biogas plants is used as enriched bio-manure to supplement the use of chemical fertilizers. The slurry bio-manure can be applied for crop production in solid, liquid or dried form.
  • It improves sanitation in villages and semi -urban areas by linking sanitary toilets with biogas plants.
  • Biogas Plants help in reducing the causes of climate change.
  • It has the potential for leveraging livelihood development as well as tackling the issues related with health hazard associated with indoor air pollution.
2)   Which of the following is/are true regarding National Biogas and Manure Management Programme (NBMMP)?

1) It is for setting up of Family Type Biogas Plants mainly for urban households.
2) The objective of the scheme is to provide clean gaseous fuel for cooking and organic bio-manure as a by-product.

a. Only 1
b. Only 2
c. Both 1 and 2
d. Neither 1 nor 2
Answer  Explanation 

ANSWER: Only 2

Explanation:

  • National Biogas and Manure Management Programme is a Central Sector Scheme, which provides for setting up of Family Type Biogas Plants mainly for rural and semi-urban/households.
  • A family type biogas plant generates biogas from organic substances such as cattle –dung, and other bio-degradable materials such as biomass from farms, gardens, kitchens and night soil wastes etc.
  • The objective of the scheme is to provide clean gaseous fuel for cooking and organic bio-manure as a by-product in the form of biogas plant left over slurry, which contains higher values of Nitrogen, phosphorus and potassium (N, P&K).
  • NBMMP also helps in mitigating drudgery of women in rural and semi-urban areas by saving in their time both in collection of firewood, making cattle dung cakes and cooking.
  • A biogas plant will facilitate in achieving sanitary in villages by linking sanitary toilets with cattle dung based biogas plants and the slurry bio-manure can be applied for crop production in solid, liquid or dried form.
