In the Flintenbreite in Luebeck, Germany, blackwater is collected in vacuum toilets. Together with organic wastes from the kitchen it is converted to biogas. Greywater is treated in a reed-bed filter. The project demonstrated the consistent utilisation of ecological building materials, the use of self-sustaining, integrated energy and wastewater concepts, and the implementation of innovative energy saving technologies, with a minimisation of interference in nature, and a responsible, integrative and active cohabitation of the inhabitants.

Some possible improvements are briefly discussed, such as the use of certain comparatively clean sludge fractions and use of two-stage technology for the recovery.

The transformation of this excess biogas into electricity would be a sustainable solution generating even additional income. An alternative to burn it in flare is the biogas conversion into electricity through engines or microturbines. This paper describes the proposed system to convert biogas in electricity and heat using microturbines (30 kW ISO).

It takes a look at some of the methods that have worked well in the past, to guide us in solving the problems of the future. By addressing sanitation as a key element of the urban metabolism, and by linking sanitation with urban planning and neighbouring sectors like solid waste management or waste recycling, it allows for a holistic approach. In the cities of tomorrow, we will need to focus more on recycling energy. A good example being biogas generation from wastewater and sludges. Water will also become an increasingly scarce commodity. Greywater (from showers and sinks) can be treated in urban constructed wetlands or used to water and fertilise urban green spaces. Such examples of productive sanitation systems will form an integral part of infrastructure in sustainable cities.
