What happens to hydrocarbons when waste polymers are combusted?

When waste polymers, which are often derived from hydrocarbons, are combusted, they can indeed provide energy resources. During combustion, the hydrocarbons react with oxygen to produce carbon dioxide and water, releasing energy in the form of heat. This exothermic reaction can be harnessed for various applications, such as generating electricity or providing heat.

The process also reflects the potential of these materials as fuel sources, given that many waste polymers are derived from petroleum-based hydrocarbons. Although it is important to manage the emissions produced during combustion, including harmful gases, the primary outcome of this reaction is the release of energy. This makes the option regarding energy resources a valid choice.

In contrast, the other options do not accurately represent the outcomes of combusting waste polymers. They do not produce no energy, nor do they revert to monomers through combustion. While harmful gases can be released during the process, the focus on energy generation as the main outcome of this combustion is what makes it the correct answer.
