What is the hardest thing to decompose?

What Cannot be decomposed?

Expert-Verified Answer

The substance that cannot be decomposed by ordinary chemical means is mercury, as it is an element and cannot be broken down further. Other options listed are compounds that can undergo decomposition. Therefore, the correct answer is option 2: Mercury.

Does glass decompose in soil?

Glass is non-biodegradable, which means it will not decompose naturally and can remain in the environment for thousands of years. In landfills, its presence contributes to the growing volume of waste. In the ocean, it can break down into smaller pieces, becoming a hazard to marine life but will not biodegrade.

What are the examples of non decomposing waste?

Examples of non-biodegradable substances include footwear, fibers, metals, poisonous chemicals, pesticides, and consumer goods like disposable bags, supermarket bags, plastic containers, water bottles, and metal cans.
