What item is more biodegradable?

Generally, organic materials such as food scraps, paper, and cotton are more biodegradable than synthetic materials like plastic. Among these, food scraps typically decompose faster due to their nutrient content, which supports microbial activity. In contrast, plastics can take hundreds of years to break down, making them significantly less biodegradable. Overall, the biodegradability of an item depends on its composition and environmental conditions.
