In which type of compositing manure takes 4 to 6 weeks?

  1. Machanical Compositing

  2. Open window composiing

  3. Worm Compositing

  4. Compositing by trenching
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Open windrow composting (also called open window composting) takes approximately 4 to 6 weeks to produce mature compost. This method involves piling organic matter in long rows (windrows) that are periodically turned to aerate the pile, accelerating decomposition. Mechanical composting is faster, while trenching takes longer.

Which type of compositing requires less land area?

  1. Manual Compositing

  2. Machanical Compositing

  3. Open Window Compositing

  4. Sea Disposal
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Mechanical composting requires less land area compared to other methods because it uses enclosed systems with forced aeration and temperature control, allowing faster decomposition in smaller spaces. Open windrow requires large land areas for rows, and manual methods need space for turning and managing piles.

Rubber cracking of tyres and electrical insulation is caused by

  1. $O _{3}$ and PAN

  2. Lead Poisoning
  3. $SO _{2}$, $NO _{2}$, $O _{3}$

  4. PAN
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ozone (O3) and Peroxyacetyl nitrate (PAN) are strong oxidizing agents found in photochemical smog that cause the degradation and cracking of rubber products.

In which method all pathogens and insects are destroyed?

  1. Incineration

  2. Landfilling

  3. Pyrolysis

  4. Composition
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Incineration involves burning waste at very high temperatures, which effectively destroys pathogens, bacteria, and insects that might be present in the waste.
