What does landfill and biodegradable mean?

Landfill refers to a designated area where waste materials are disposed of by burying them underground, often leading to environmental concerns such as soil and water contamination. Biodegradable materials, on the other hand, are substances that can break down naturally through the action of microorganisms, returning to the environment without causing harm. Unlike waste in landfills, biodegradable materials can decompose in a relatively short time, contributing to a more sustainable waste management approach.
