Solid waste materials are useless materials that result from various human activities, including domestic trash, garbage, metal scrap, and more.

These materials have a direct impact on the environment, causing both land and water pollution.

With the increase in industrialization and urbanization, many waste materials are directly exposed to nature, harming plants and animals.

In today’s world, we rely heavily on ready-made and artificial products, resulting in increased soil waste and related problems.

To manage this unwanted solid waste, the 5R principle has been introduced.
