MATERIALS

This guide outlines the decomposition times of various materials, highlighting the significant environmental impact of waste. Paper products, such as paper and cardboard, decompose in weeks to months, while plastics can take decades. Aluminum products require hundreds of years to break down, and Styrofoam can persist for up to 2000 years. Glass is particularly concerning, with an estimated decomposition time of 1 to 2 million years. Understanding these times can foster awareness about recycling and waste reduction efforts.
