Bauen ist heute verbunden mit einem enorm hohen Energieverbrauch, Rohstoffeinsatz und Reststoffanfall. Die Herstellung und der Transport von Baustoffen zum Einsatzort benötigen gewaltige Mengen an Energie und die Prozesse sind nach wie vor mit einer erheblichen Emission von CO2 und weiterer klima‐ und umweltschädlicher Stoffe und Substanzen verbunden. Die Bündnisregion (ca. 80‐km‐Radius um Weimar) verfügt über erhebliche Rohstoffressourcen für die Baustoffindustrie und liegt dadurch im Fokus des überregionalen Bausektors, was der nachhaltigen Nutzung der Landschaftspotenziale entgegensteht. Bauen wird nur dann nachhaltig sein können, wenn über wegweisende Innovationen der Roh‐ bzw. Baustoffeinsatz drastisch reduziert, Herstellungs‐ und Verarbeitungsprozesse deutlich effizienter gestaltet und Stoffkreisläufe konsequent geschlossen werden. Das im Rahmen von WIR! (Wandel durch Innovation in der Region) durch das BMBF finanzierte Bündnis RENAT.BAU betrachtet deshalb das Bauen konsistent über gesamte Stoffströme und vollständige Lebenszyklen und Wertschöpfungsketten hinweg.

Abstract: As Germany's most important, domestic fossil energy carrier, lignite plays a crucial role in electricity and heat production. Even though its share of the overall power production is decreasing due to a rising feed‐in from renewable energy sources, fossil energy carriers will go on providing base load and back‐up electricity in times when renewable energies are not able to produce enough electricity. Lignite and byproducts can also be used for material utilization. The production of hydrocarbons or extraction of important raw materials are examples. [ABSTRACT FROM AUTHOR]

Space, and access to resource deposits in particular, is a central theme of studies in economic history. However, new approaches to the theory of space that highlight the relations between people, places and things as constituents of multiple and dynamic spaces, have so far rarely been systematically applied to questions relating to resource economies. By referring to spaces of resource extraction as 'sites', this introductory article develops the notion that spaces in which resources are accessed, distributed and consumed are not a fixed and pregiven category, but exist in dynamic spatial relations. These spatial relations can be made up of perceptions and images, such as geological knowledge or spheres of interests, social structures, such as in the distribution of real-estate property and in power relations, or they can be established by the expansion of infrastructures and by terms of trade. They also pertain to the physical properties of the resources themselves, especially when considering the environmental impact of extraction. All of these spatial relations are highly variable and change historically in interdependence with the dynamics of resource extraction. [ABSTRACT FROM AUTHOR]
