Waste encapsulation is a method used to safely contain hazardous materials, preventing them from leaking into the environment. This process involves enclosing waste in a stable material, such as concrete or glass, which helps to immobilize harmful substances and reduce their potential impact on soil and water. The encapsulated waste is then stored in secure facilities designed to isolate it from the surrounding area. This technique is commonly applied in the management of nuclear waste and other toxic materials, ensuring that they remain contained for long periods while minimizing risks to public health and the environment.
