Question

which of these items in garbage has the highest btu content when burned? glass banana peels plastic

Explanation:

BTU (British Thermal Unit) is a measure of energy content. Glass does not burn (it is non - combustible), so it has no BTU content from burning. Banana peels are organic matter, but they have a relatively low energy density compared to plastics. Plastics are hydrocarbon - based materials (similar to fossil fuels in some ways). Hydrocarbons have a relatively high energy content when burned. When plastics are burned, they release a significant amount of energy in the form of heat, which is measured in BTU.

Answer:

plastic
