Regenerative Energie
The Airflow technology implemented by Spinoff is a promising option for the reduction of long term environmental impacts of landfills and for the remediation of old landfills by means of low pressure in situ aeration. Proper investigations and preliminary tests are necessary to obtain all
the necessary information to carry out the design of an in situ aeration plant and an effective monitoring of the stabilization process during the operation. After the usual investigation on the site conditions in terms of current emissions, status of waste biological stabilization, expected impacts, etc.), it is necessary to carry out a mass balance of the organic carbon in the landfill, with the goal of evaluating the amount of carbon removable as CO2 in the extracted gas during the in situ aeration and compare it with what expected in the traditional anaerobic landfill.
The in situ aeration of Municipal Solid Waste landfills enhances the stabilization processes of the biodegradable organic substance, resulting in an improvement of the quality of emissions. The full scale application of the in situ aeration requires, besides the usual preliminary investigations for site characterization in terms of waste and emission quality, the evaluation of relevant parameters for the design of the in situ aeration plant, such as the radius of influence of air injection and gas extraction wells, the pressure field in the landfill body during the aeration process as well as the amount of carbon removable as CO2 in the extracted gas. This paper provides some examples of preliminary tests carried out at lab scale and in situ for the evaluation of the abovementioned parameters and two full scale applications of in situ aeration by means of the Airflow technology are briefly presented and discussed.

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.
