<p>Starting point to this Paper is the idea and wish to adapt the society and its different activities to a recycle society. A building area in Göteborg is planned and investigated for such adaptation. In the district named Skogaberg, about 130 households totally are planned from what 20 are blocks of flats. The idea with this project is to constitute an alternative sewage system, a Blackwater system, were the fractions of most nutrients and least pollution are separated, taken care of and utilised. The aim is to get a market and use the nutrients of the organic waste from the household in agriculture use. The Swedish Environmental Protection Agency (EPA) pays attention to water- and sewage systems from a recycle perspective and the aim of a long-termed sustainable development. The agriculture sector has also an intention to protect the environment and the means for sustainability. </p><p>The object of this study is to map and analyse a planned alternative sewage system in Skogaberg from recommended criteria for water and sewage systems. The alternative solution in Skogaberg will be analysed compared to a conventional solution. A specific aim is to estimate the possibilities and limitations of the alternative system when it comes to recycle of nutrients. Phosphorus and cadmium are chosen to describe and indicate the resource utilisation and environmental impact of different nutrient sources. Sanitation and risks with diseases, environmental&resource saving criteria together with technical&socio-economic criteria are intended to constitute a general background for the analysis. Criteria recommended, to concern environmental adapted water and sewage system by the Swedish EPA, is used in order to make an assessment of the planned system and a more viewed assessment and analyse is done from experiences and observations that I have got from literature sources and place studies. The results show good theoretical possibilities to get and recycle nutrients from the system with an alternative solution. With an alternative sewage system in Skogaberg opportunities that the users reflect and care are created. This project may provide us with innovations and ground for further research and development in future project. But it is also important to consider that these projects are established in the system of the society and that these recycle systems are not directly comparable with ecological recycling system in nature.</p>
