Coal is NOT a renewable resource because once it is used (burned) it cannot be recycled or used again.
Sulfur is considered a non-renewable resource since it is primarily extracted from natural deposits, such as volcanic regions and salt domes, and cannot be replenished on a short timescale. However, it is abundant in nature and can be recycled from certain industrial processes.
Steel is not a natural resource. It is a metallic alloy of iron and carbon. Iron is the natural resource and mining it has and will have many consequences on the environment. Iron will be harder and hard to mine and steel now has become one of the most recycled metals.
No, plastic is not a renewable resource. It is primarily derived from nonrenewable fossil fuels such as oil and natural gas through a chemical process. Once plastic is created and used, it cannot be easily recycled back into its original form.
Yes magnesium is a resource but it cannot be classified as energy resource.Magnesium is a metal.

No, a bicycle is a manufactured item (it does not grow or form naturally). Many of the materials used in manufacturing bicycles (steel) can be recycled, and some may be natural (natural rubber tyres, leather seats) but this does not make it a renewable resource.
Bismuth is a nonrenewable resource but wastes can by recycled.
When a natural resource cannot be REPLACED (not 'reused', which is the wrong terminology).
No they cannot be recycled.
