ABSTRACT
Towards a sustainable society, a recycling and recovery of products together with handling of scarce
resources must be considered. In this article arguments for source separating systems and end-of-pipe
solutions for urban wastewater systems are investigated and compared to the close by sector- the handling of
solid wastes in households. In Sweden, the handling of solid wastes has come far with recycling of products.
The responsibility is on the individual basis to sort out the wastes at the source. The development in urban
wastewater systems has not reach the recovery level yet, but the legislations and environmental aspects are
implying to go from removal to recovery.
A comparison was made between a source separating system and an end-of-pipe solution. The result showed
that the end-of-pipe solution was favoured in most of the criteria, as the criteria were seen as equally
important. A strong argument for end-of-pipe solutions is that the future urban environment will be a dense
city, which creates strong motives to build further on the central systems already existing. Furthermore,
larger organisational resources and dialog between actors are demanded when introducing the source
separating systems compared to what is demanded for conventional systems. In addition to that, the local
solutions are considerable more expensive than when the city is fully connected to the large scale system.
However, it is likely to believe a recovery from WWTP will take place in a dense city and in more scarcely
populated areas source separating systems may appear
