22045 Hamburg-JenfeldHAMBURG WATER Cycle®, an urban quarter with 835 residential units, 630 of them in new buildings, and commercial space for around 2000 residents is being built on 35 ha of the former Lettow-Vorbeck barracks. Project costs: approx. 250 million euros. The most far-reaching project of a decentralised water supply and disposal system currently in Europe: vacuum toilets, biogas production and waste water separation (HAMBURG WATER Cycle®). The biogas produced will be used to generate heat and electricity for the new district in a climate-neutral manner in the district's own combined heat and power plant. The project will thus enable climate-neutral living and sustainable drainage.

74549 Wolpertshausen: Bioenergiedorf mit Ökosiedlung. 1.800 EW. Ca. 50% Erneuerbare Energien. "Ecological residential area Wolpertshausen" wird komplett über Nahwärme bzw. von Biogas-Gemeinschaftsanlage (Inbetriebnahme: 1996) versorgt.
75438 Knittlingen (near Pforzheim): 100 houses. Collection of black water via vacuum toilets (5 - 10 times less water per flush) and shredded kitchen waste (organic waste bin no longer required), which is then converted into biogas. The waste water is treated and is available again as germ-free care water that fulfils the requirements of the Drinking Water Ordinance. DEUS 21 was honoured with the Joseph von Fraunhofer Prize in 2007. The plant has been in operation since around 2004 and is a project of the Fraunhofer Institute IGB, Stuttgart and the FhG ISI Institute for Systems and Innovation Research, Karlsruhe.
76228 Karlsruhe-Hohenwettersbach: "50 Morgen": 150 WE. Verschiedene Architekten und Bauträger u.a. P.I.A., Gisa und Ingo Bohning, LEG Baden-Württemberg. Energieversorgung erfolgt über ein Nahwärmenetz, das von einem Block-Heiz-Kraft-Werk (BHKW) Strom und Wärme bezieht. Das BHKW verbrennt Biogas, das aus einem Teil der Karlsruher Bioabfälle gewonnen wird. Teilweise wurden die Gebäude in Passivhaus- Bauweise realisiert und ökologische Materialien verwendet. Fertigstellung: 2004
