Non biodegradable waste is waste that does not break down into natural components and exists in the environment for a long time. Examples would be tyres, plastics, electronic components, metals etc

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.

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.

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.

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 $D$

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.

Biodegradable substances are those materials or products that are able to naturally break down or decompose without causing any harm to the environment. Biodegradable substances are generally things that are organic in nature. This means they are substances that are made from things that were living at some point. Examples of biodegradable substances include paper which is made from trees, meat products which come from animals and leather products.

Not all synthetic polymers are biodegradable substances. Most of the synthetic polymers, including polythene and polypropene are not biodegradable.

Groundwater moves through soil and rocks, picking up pollution along the way. Plastic trash can affect groundwater quality, especially if you dispose of it improperly. It reduces the percolation of water as it comes in the way as water moves through soil.
