How we throw energy away


This article seeks to analyse, in the most up-to-date mannerpossible, the MSW situation in Spain, with special emphasis on the energy recovery of reject remaining after pretreatment,sorting and separation of recyclable materials. A great dealof this reject goes to landfill, with a corresponding wasteof potential energy in a country that imported 75.4% of its primary energy in 2011

Words such as rubbish or junk, which until recently meant something with no use that generally smelt bad and whose meaning has been diluted by their use in terms such as “junk bonds, “junk television”, “junk contracts”, “junk food”, etc, must be eliminated from household vocabulary as
soon as possible. However, the basic meaning retains its significance due particularly to the enormous quantities of waste generated in all countries. And the more developed the country, the more waste is generated.

The concept of Municipal Solid Waste (MSW), made up of domestic waste and other assimilable commercial and/or industrial waste generated in urban areas, lends meaning to the word “waste”, which is officially defined as “…any substance or object which the holder discards or intends or is required to discard…” (Directive 2008/98/EC).
