TOWERING INFERNO Reaches Sky-High Efficiency - Waste Management World

Again and again we hear the message that resources are scarce, and that we have to ensure that they are not lost in our waste. Explanations as to which resources we are talking about and how we avoid wasting them, however, are in short supply.

Waste may contain many different resources depending on origin and prior use. The resources of waste may be considered a material resource, an energy resource or a nutrient resource, and typically a waste fraction will comprise a mixture of these in varying quantities.

When evaluated from a materials and nutrients point of view, however, many waste fractions do not contain any significant recyclable resources without them first being subjected to thorough sorting and cleaning processes – processes which both economically and in terms of energy are very costly. At modern waste to energy facilities with combined heat and power production a highly efficient recovery of the most important resource of these waste fractions - energy - can be ensured.
