2.A.2 - Lime Production

Short description
The statements made below regarding source category 2.A.2 refer solely to the amounts of burnt lime and dolomite lime produced in German lime works. Other lime-producing processes are included in NFR 2.C.1 and 2.H.2. Information about key source relevance you find within the overview '2.A'.

Because of the wide range of applications covered by the sector's products, lime production is normally more isolated from economic fluctuations than is production of other mineral products such as cement. Production has fluctuated relatively little since the end of the 1990s. Dolomite-lime production, of which significantly smaller amounts are produced, basically exhibits similar fluctuations.

Method
The pertinent emissions level is obtained by multiplying the amount of product in question (quick lime or dolomite lime) and the relevant emission factor.
Activity data
The German Lime Association (BVK) collects the production data for the entire time series on a plant-specific basis, and makes it available for reporting purposes. Production amounts are determined via several different concurrent procedures; their quality is thus adequately assured (Tier 2). Most companies are also required to report lime-production data within the framework of CO2-emissions trading. The EU monitoring guidelines for emissions trading specify a maximum accuracy of 2.5 %.

Trends in emissions

All trends in emissions correspond to trends of emission factors in table above. No rising trends are to identify.

Recalculations

Recalculation activities were done for time series consistency regarding the fuel related emissions. As a result between 1990-1994 emissions of NOx, SO2 and NMVOC have been increased.
