What category of waste would "buns" fall under in the waste management system?

The category of waste that "buns" falls under in the waste management system is food waste. This classification is based on the nature of the item, as buns are organic materials that are typically considered kitchen waste, primarily due to their composition of ingredients that can decompose.

Food waste is generally defined as any edible items that are discarded, whether they are spoiled, leftover, or unsold items that cannot be reused or consumed. This category focuses on reducing the environmental impact by managing how such waste is treated, often through methods such as composting or donation to food banks.

Other categories, such as paper or recyclables, involve materials that can be processed and reused, while hazardous waste pertains to items that pose risk to health or the environment. Buns do not fit those definitions, making food waste the appropriate classification.
