  1. Paper

  2. Plastic

  3. Chemicals

  4. None of the above

B Correct answer
Explanation
Since plastics take several years to decompose, they are not environment friendly and cause pollution. When animals eat them, plastics remain stuck in their organs and cause severe damage, sometimes leading to death.

Which of the following statement is true about non-biodegradable materials?

  1. They are safe for environment

  2. The wastes are made up of synthetic material

  3. They can be constantly reused

  4. The wastes are made up of natural ingredients
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Non-biodegradable materials are those which do not decompose by natural processes. Non-biodegradable materials are generally synthetic polymers. They are not safe for the environment. Natural fibres degrade very easily in nature. However, non-biodegradable materials are made up of synthetic materials which are not broken down by micro-organisms.

Which of the following item cannot be recycled?

  1. Plastic milk bottles

  2. Plastic food trays

  3. CD/DVD cases

  4. Plastic cups
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Plastic containers are relatively dense and compact which enables them to be easily sorted mechanically, into the different types of plastics. Plastic film and bags are not easily mechanically sorted making them very costly to sort. Also, recycling such plastic is an expensive process.

CVD/DVD cases are made up of thermosetting polymers which can not be recycled.
Option C is correct.

______ is an example of biodegradable .

  1. Thermal power plants

  2. Fertilizer industries

  3. Steel plants

  4. Cotton mills
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Cotton mills  (cotton clothes) is an example of biodegradable.
Other biodegradable materials are paper, wood, peels of vegetable and fruits, leftover foodstuff, woollen clothes etc.
Non-biodegradable materials are plastic bags, tin, aluminium, and other metal cans.

Note : Biodegradable waste consists of plant and animal waste that is broken down by other living organism. It is produced in industries like cotton mills, food processing units, paper mills and textile factories.

A Correct answer
Explanation

Biodegradable waste consists of plant and animal waste that is broken down by other living organism, substances that are broken down by biological processes are said to be biodegradable. Biodegradable waste products can also be called green waste, food waste, or organic waste.

Multiple choice chemistry man made materials plastic and environment pollution due to plastics environmental impact: plastics

Burning of plastic causes :

  1. water pollution

  2. air pollution

  3. sound pollution

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Plastics is burnt which releases toxic gases like Dioxins, Furans, Mercury and Polychlorinated Biphenyls into the atmosphere. Further, burning of Poly Vinyl Chloride liberates hazardous halogens and pollutes the air, the impact of which is climate change. The toxic substances thus released are posing a threat to vegetation, human and animal health and environment as a whole. These gases cause air pollution only.

Multiple choice chemistry man made materials plastic and environment pollution due to plastics environmental impact: plastics

 Disposable plastic plates should not be used because:

  1. They are made of materials with light weight

  2. They are made of toxic materials

  3. They are made of biodegradable materials

  4. They are made of non-biodegradable materials
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Disposable plastic plates should not be used because its waste is non-biodegradable and cannot be broken down into its base compounds by micro-organisms, air, moisture or soil in a reasonable amount of time. Non-biodegradable waste is an environmental concern, as it threatens to overwhelm landfills and create disposal problems.

Hence, the correct option is $D$

Multiple choice chemistry man made materials plastic and environment pollution due to plastics environmental impact: plastics

Non-biodegradable substance releases harmful gases when burnt.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Non-biodegradable products include plastic products, metal products, construction waste, electronics etc. Non-biodegradable products are items that cannot decay or be broken down by living organisms. The bio-degradable substances leach out toxic chemicals when they are burnt and are harmful to health.
