Questions Related to conservation of environment

Resource recovery is also known as 

solid waste and its management conservation of environment

  1. Reuse

  2. Recycle

  3. Reduce

  4. All of the above

Show answer
Correct Option: B
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.

 The rate of pyrolysis increases with 

solid waste and its management conservation of environment

  1. Temperature

  2. Pressure

  3. Preciptation

  4. None of the above

Show answer
Correct Option: A
Explanation:
Pyrolysis is the process of breaking organic compounds in the presence of heat but in absence of oxygen. The process accelerates with increase in temperature. 
So, the correct answer is 'Temperature'

Waste minimization targets at

solid waste and its management conservation of environment

  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

Show answer
Correct Option: D
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.

solid waste and its management conservation of environment

  1. Automated vacuum collection

  2. Curbside collection

  3. Pyrolysis

  4. None of the above

Show answer
Correct Option: B
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. 

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

solid waste and its management conservation of environment

  1. Landfill

  2. Incineration

  3. Recycling

  4. None of the above

Show answer
Correct Option: B
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.

Incineration is also known as 

solid waste and its management conservation of environment

  1. Thermal treatment

  2. Landfill

  3. Decomposition

  4. None of the above

Show answer
Correct Option: A
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 A.

Processing is a step during waste management which means

solid waste and its management conservation of environment

  1. Operation to convert a material into a non-biodegradable waste

  2. Operation to convert a material into a useful product

  3. Operation to convert a material into a weedicides

  4. None of the above

Show answer
Correct Option: B
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. Processing during 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 minimisation can improve

solid waste and its management conservation of environment

  1. Efficient production practices

  2. Economic returns

  3. Quality of products produced

  4. All of the above

Show answer
Correct Option: D

Waste hierarchy gives information about

solid waste and its management conservation of environment

  1. Waste minimization

  2. Incineration

  3. Recycle

  4. None of the above

Show answer
Correct Option: A
Explanation:

Answer is option A i.e. "Waste minimization"
Waste Hierarchy is based on the principle that it is better to not to create waste. It helps in managing waste according to best for the environment. The aim of the waste hierarchy is to extract the maximum practical benefits from products and to generate the minimum amount of waste.

Eco save toilets are working in many areas of

solid waste and its management conservation of environment

  1. Assam and West Bengal

  2. Kerala and Sri Lanka

  3. Maharashtra and Andhra Pradesh

  4. Karnataka and Sri Lanka

Show answer
Correct Option: B
Explanation:
Ecological sanitation is a sustainable system for handling human excreta, using dry composting toilets. This is a practical, hygienic, efficient and cost-effective solution to human waste disposal. With this composting method, human excreta can be recycled into a resource (as natural fertilizer), which reduces the need for chemical fertilizers. There are working ‘EcoSan’ toilets in many areas of Kerala and Sri Lanka. 
So the correct answer is 'Kerala and Sri Lanka'.
