Which of the following is an important step before the last step of solid waste management?

  1. Collection

  2. Recovery

  3. Disposal

  4. None of the above

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

There are various steps which are involved in the safe management of the solid waste. Reduce, reuse, recycling, sorting, processing, recovery and disposal are major steps of integrated waste management. The important step before the last step is the energy recovery. The forms of wastes which can be recovered to obtain energy can be segregated and the remaining waste forms can be disposed. This reduces the energy which will be required for the transport and the final disposal of the waste.

Thus, the correct answer is option B.

Resource recovery is also known as 

  1. Reuse

  2. Recycle

  3. Reduce

  4. All of the above

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

There are different waste management strategies for waste minimization. The aim of the waste management is to obtain the maximum benefits from products and to generate the minimum amount of waste. Resource recovery in the waste management process is a step of converting a waste material into a useful product. It is called as recycling. 

Thus, the correct answer is option B.

Waste minimization targets at

  1. Reducing the amount of waste produced in society

  2. Preventing the creation of waste

  3. Supporting the efforts to promote a more sustainable society

  4. All of the above

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Waste minimisation is the method which aims at reducing the amount of waste which is generated. The waste which is generated can be reduced at the society level. There should be a decrease in the production or creation of the wastes. The used products can be transformed and used again, instead of throwing the substance as waste. Waste minimisation is one of the methods which can help to promote a sustainable society.

Thus, the correct answer is option D.

 ............ is the most common method of disposal in most European countries.

  1. Automated vacuum collection

  2. Curbside collection

  3. Pyrolysis

  4. None of the above

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Curbside collection is the method of waste disposal in the European countries. There are special bins which are used for the collection of the wastes from the residential areas. The wastes are then recollected in special trucks. These trucks are used for the transport of the wastes to the areas outside the premises of the city.

Thus, the correct answer is option B. 

Multiple choice solid waste and its management conservation of environment

 ............. is a disposal method in which solid organic wastes are subjected to combustion.

  1. Landfill

  2. Incineration

  3. Recycling

  4. None of the above

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Incineration is a waste treatment process that involves the combustion of organic substances contained in waste materials. Incineration can be described as thermal treatment. Incineration of waste materials converts the waste into ash, flue gas and heat. 

Thus, the correct answer is option B.
