What is the decomposition time for glass bottles?

The decomposition time for glass bottles is approximately 500 years. This means that once discarded, glass bottles take a very long time to break down in the environment. Glass is made from silica (sand), and it is a highly durable material. Unlike organic materials that can decompose relatively quickly due to biological processes, glass remains intact for centuries. The long decomposition time highlights the importance of recycling glass bottles and reducing waste, as they contribute significantly to landfill mass if not properly managed.

The other options, though they suggest long decomposition times, do not accurately represent the consensus on glass bottles. While glass does take a long time to decompose, the notion of 700 years is an exaggeration, as is the idea that it could significantly decompose in less than 500 years, which would underestimate its durable nature.
