+ | In 2004, about 2000 landfills of relevance for this category were in operation in the Federal Republic of Germany.\\ | ||
+ | In June 2005, in keeping with new, stricter requirements under the Ordinance on Environmentally Compatible Storage of Waste from Human Settlements (Abfallablagerungsverordnung) and the Landfill Ordinance (Deponieverordnung), | ||
+ | Also, pursuant to regulations in force since June 2005, landfilling of biodegradable waste is no longer permitted - for conformance with pertinent requirements, | ||
+ | All these measures have had strong impact on the formation of NMVOC, PM< | ||
+ | |||
+ | ===== Methodolgy ===== | ||
+ | For the estimation of NMVOC, Germany decided against the proposed EF of the EMEP/EEA Guidebook 2019, but instead for the Tier 1 approach of the US-EPA which is also reproduced there (Part B, 5.A, chap. 3.2.2, p. 5; [(EMEPEEA2019> | ||

+ | Emissions for PM< | ||
+ | The EFs are multiplied with the total amount of solid waste (AD) treated in managed above-ground landfillings, | ||
+ | |||
+ | **EM = AD * EF** | ||

+ | ==== Activity data ==== | ||
+ | Data from 1990 until 2005 are made available for the UBA by the National Statistical Agency by means of a direct data provision (Statistisches Bundesamt, January 2019; [(Statistisches Bundesamt, Data provision by Mail, 14.01.2019; Data are confidential; | ||

+ | From 2006 until today, Official statistical data (Statistisches Bundesamt, Fachserie 19, Reihe 1: Abfallentsorgung (Waste management), | ||
+ | |||
+ | ==== Emission factors ==== | ||
+ | See above under Methodology. | ||
+ | |||
+ | ===== Uncertainties ===== | ||
+ | The AD from Statistisches Bundesamt usually have an uncertainty of ±3% whereas the uncertainties for the PMs and TSP emission factors, according to the EMEP/EEA Guidebook (Part B, 5.A, chap. 3.2.2, Table 3-1, p. 5), were estimated to be: | ||
+ | |||
+ | ^ PM< | ||
+ | ^ PM< | ||
+ | ^ TSP | ||
+ | |||
+ | Due to the fact that for the ratio of NMVOC and CH< | ||
+ | |||
+ | ===== Recalculations ===== | ||
+ | Regular back-calculations are required annually for the previous year, since the waste statistics of the Federal Statistical Office are published with a one-year delay for the data on the quantities and compositions of waste deposited, so that the current reporting year must therefore be estimated. The estimate is replaced in the following year with the then current data.\\ | ||
+ | Since the recalculation required as a result is very small overall in each year, it will not be reported additionally here. | ||
+ | |||
+ | However, in this year's reporting the need for correction of PM and TSP is higher than usual and thus a recalculation is reported (see following table). | ||
+ | |||
+ | Recalculation: | ||

+ | | PM 2.5 [t] | NIR 2022 | 1, | ||
