AbstractCouncil Directive 96/61/EC concerning integrated pollution prevention and control (IPPC) is an important EU framework regime for the control of polluting emissions from major industrial sources. The concept of BestAvailable Techniques (commonly known as BAT) is the core element of the Directive and permits issued for industrial installations need to take account thereof. Therefore, the proper implementation of the IPPC Directive vis-a-vis individual installations can be assessed, among others, on the basis of whether or not BAT applies. Whilst the concept of Best Available Technology (used by the predecessor of the IPPC Directive) is less stringent, the European Court of Justice has taken a strict approach regarding its application by Member States and the adaptation of existing installations to this concept.

L’Autorizzazione Integrata Ambientale (AIA) è il provvedimento che autorizza l’esercizio di un impianto o parte di esso, in cui si svolgono attività che potrebbero causare significativi impatti ambientali. Con l’AIA le imprese possono uniformarsi ai principi di IPPC che sta per Integrated Pollution Prevention and Control, individuando soluzioni tecniche, impiantistiche ed economiche, per una corretta gestione delle possibili forme di inquinamento. Per raggiungere elevati livelli di protezione dell’ambiente bisogna adottare le Migliori Tecniche Disponibili, in inglese Best Available Technology (BAT). Ad oggi in Italia non è ancora presente un metodo di studio delle migliori tecnologie disponibili, ma una diversa situazione si ha nel Regno Unito dove viene il software H1. Lo scopo del presente lavoro è individuare una metodologia di studio delle BAT per un impianto di trattamento della Frazione Organica dei Rifiuti Solidi Urbani (FORSU) e scarti ligneo-cellulosici per la produzione di biometano situato in Italia, applicando per lo stesso il software inglese.

Abstract. Aerosol acidity plays a key role in regulating the chemistry and toxicity of atmospheric aerosol particles. The trend of aerosol pH and its drivers are crucial in understanding the multiphase formation pathways of aerosols. Here, we reported the first trend analysis of aerosol pH from 2011 to 2019 in eastern China. The implementation of the Air Pollution Prevention and Control Action Plan leads to −35.8 %, −37.6 %, −9.6 %, −81.0 % and 1.2 % changes of PM2.5, SO42−, NHx, NVCs and NO3− in YRD during this period. Different from the fast changes of aerosol compositions due to the implementation of the Air Pollution Prevention and Control Action Plan, aerosol pH shows a moderate change of −0.24 unit over the 9 years. Besides the multiphase buffer effect, the opposite effects of SO42− and non-volatile cations changes play key roles in determining the moderate pH trend, contributing to a change of +0.38 and −0.35 unit, respectively. Seasonal variations in aerosol pH were mainly driven by the temperature, while the diurnal variations were driven by both temperature and relative humidity. In the future, SO2, NOx and NH3 emissions are expected to be further reduced by 86.9 %, 74.9 % and 41.7 % in 2050 according to the best health effect pollution control scenario (SSP1-26-BHE). The corresponding aerosol pH in eastern China is estimated to increase by ~0.9, resulting in 8 % more NO3− and 35 % less NH4+ partitioning/formation in the aerosol phase, which suggests a largely reduced benefit of NH3 and NOx emission control in mitigating haze pollution in eastern China.
