1.3 The role of the households
An improved sustainability of the urban infrastructure may be reached with help of technical
arrangements and suitable management systems. The growing chemical society has changed an
earlier perception that the technical system can be developed and manage all kind of use included
the misbehaviour of the households. The environmental actions of the accommodator have therefore
been more important to a good functional infrastructure of water, waste and energy and the
accommodators are integrated again in the management system states Drangert (2004).
The role of the households has changed during the last decades and may be described as from
anonymous users to a costumer in a municipally or private owned company, and latest as a partner
in the recycling work. The change has a decisive influence on the relations between property
constructors, the recycling companies and the users.
