Chemical-physical treatment facilities for hazardous fluid wastes represents an important disposal path in Austria. Therefore, two studies (IAE in order for the province of Styria, the Federal Environment Agency) were carried out, which deals with the potential waste input, facility capacities, prevailing configurations and the difference between state of the art and best available techniques in this kind of waste disposal.
Existing facilities could be distinguished by the treated waste in inorganic (CPA), organic (CPO) and combined (CPAO) systems. Depending on the system capacity it can be further divided into non-IPPC and IPPC facilities, according to the IPPC directive. Therefore plant operators have to implement the state of the art or the best available techniques for the treatment.
In Austria, are currently more than 30 physical-chemical treatment facilities for organic and/or inorganic contaminated waste in operation, which together have a maximum treatment capacity of approximately 800,000 tons per year. These are 24 classic, two mobile and seven other chemical-physical treatment plants. Furthermore, one for the chemical-physical waste treatment also the solidification and immobilization of sludge.
An allocation of different kinds of waste only through the national and european waste catalogue to physico-chemical treatment facilities of CP systems is partially difficult. The consistency and composition (e.g. solid content and concentration of heavy metals) are main parameters for the treatment technologies in this facility types. According to legal requirements resulting from the emissions (waste gas, waste water) during the treatment, analysis of the input waste and of the reaction control during treatment as soon as a monitoring of the chemical reaction products are of exceptional importance.
Depending on the composition of the assumed wastes different aims are persuaded through the physico-chemical treatment by the plant operator. These aims could also vary in their priorities. Possible objectives could be:
- Separating of the aqueous phase (increasing the dry substance),
- Separation of recyclable material phase (e.g. oil),
- Concentration of pollutants/immobilization and
- Detoxification trough redox reactions.

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.
