Regenerative Energie
By converting anaerobic landfills into an aerobic, biologically stabilised state through accelerating organic matter degradation, the time and effort necessary for post-closure management can be shortened. In-situ landfill aeration is thereby a promising cost-efficient treatment method to significantly reduce environmentally relevant and current emissions from existing municipial solid waste landfills (MSW), to stabilise the organic waste material, and to reduce the Emission potential.
In Austria, one of the first full-scale application of in-situ aeration by means of low pressureair injection was implemented on an old MSW-landfill in autumn 2007, intended to run for about five years. About 200,000 Mg of untreated municipal and commercial waste were deposited between 1976 and 1995. The first part of the old landfill (VA01) was closed in 1985; the second landfill section (VA02) started operation in 1986 and was closed in 1995. The depth of disposed solid waste is between 3 and 18 m. The in-situ aeration plant consisted of gas wells for aeration and collection of exhausts as well as a biofilter for off-gas purification. The aeration plant was operated from end of January 2008 till end of April 2013 with a total of 31,550 operation hours (69 % degree of effi ciency). Within this time about 24.6 million m³ air was blown into the landfill body leading to about 780 m³/h input (or 0.004 l air (kg dry matter * h).

Die innerstaatliche Umsetzung des Pariser Klimaschutzübereinkommens
- ein Rechtsvergleich

Like all public international law treaties, the Paris Climate Accords rely on national law for their implementation. The success of the agreement therefore depends, to a large extent, on the stepstaken or not taken by national governments and legislators as well as on the instruments and mechanisms chosen for this task. Against this background, the present article compares different approaches to the implementation of the Paris Agreement, using court decisions as a means to assess their (legal) effectiveness.
