Regenerative Energie
Phosphorus is an important element for the fertility of soils. The actual practise in waste elimination causes important losses of phosphorus coming from the incineration of sewage sludge and then burning of bone and meat meal in plants, which do not allow recovering the phosphorus.
Sewage sludge was used as fertilizer in agriculture in Switzerland since the beginning of modern waste water treatment. During the last 40 years several difficulties arose with the agricultural use. The problems with pathogenic germs could be solved with a prepasteurisation. The contamination with heavy metals was reduced during the years but remained a cause for concern. The fear of mad cow disease and the contamination with persistent organic pollutants were 2003 the reasons for a ban of sewage sludge in the Swiss agriculture. At present the recycling of the phosphorus contained in sewage sludge and in other wastes is a goal of the Swiss policy.

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.
