Not only collection and separation…
The first step of a waste management system is reduction and complete collection of waste as well as separation for recycling of waste fractions which have a market value. But in many cases, environmental stewardship stops there.
A modern waste management system does not only focus on protecting health and environment, it also makes maximum use of the waste to reduce the exploitation of our limited natural resources. This applies to densely populated and highly industrialized countries just as it does to rural regions worldwide.
..but also thermal waste treatment
For this reason recovery of materials and energy from waste by thermal & biological waste treatment is an integral part of any modern waste management system which does no longer focus on discarding waste but on maximized utilization of all resources contained in the waste with minimized burden on society and environment.
