Regenerative Energie
The paper is about the processing and recycling of cuttings from well bores. The aim of this project is to decrease the environmental impact of drilling for oil and gas (Zero Waste Concept).
Every year approximately 5,000 tons of cuttings accumulate for every well being drilled in Aus-tria. These cuttings consist of the ground rock formation. The composition of the cuttings de-pends on the geology and the composition of the drilling fluid. In Austria the most common components are limestone, sandstone, clays and gypsum. These cuttings have to be removed from the drilling fluid and then either landfilled or recycled. Nowadays to decrease the envi-ronmental impact recycling is becoming more and more common practice. Due to the inhomo-geneous nature of the product its high residual water content and the fact that the cuttings are polluted with hydrocarbons and chemical substances that are added to the drilling mud it is not easy to find a use for it. So far most cuttings are used as fillers or as minor additional constitu-ents in the building industry. Due to the low quality of the products the building industry charg-es money for the recycling of cuttings. Therefore finding ways to reduce the water content, in-crease the homogeneity and or reduce the content of pollutants could create a product that can be sold rather than a product that one has to pay to get rid of and even open up new markets.

Transformatives Klimarecht: Raum, Zeit, Gesellschaft

This article contends that climate law should be conceived as inherently transformative in a double sense. The law not only guides the necessary transformation of economy and society, but is itself undergoing transformation.
