waste management — English
The environmentally responsible discarding of any substance that humankind has no use for anymore. Waste may be solid, liquid or gaseous. It might be bulky, but harmless or small and highly toxic. It might require treatment like incineration (see “incineration”). Years before environmental management became a recognised field of study and integrated environmental management systems were developed, various waste management systems were already used in different parts of the world and humankind had attempted to manage waste disposal. Now it is a specialised branch of environmental management. (See “environmental management” and “hazardous waste”). Always remember the most important environmental rule is: “there is no away”.
