5 Reducing CO 2 Two cases from the Industrial Minerals Industry: 1. CO 2 as a feedstock in a production process Case of PCC production 2. Autogenous CO 2 sequestration Case of lime-based mortars

6 Precipitated Calcium Carbonate (PCC) Total market in Europe: PCC: +/- 2.1 Mtonnes PCC is used in a wide variety of applications: Source: Based on Roskil (2012): Ground and Precipitated Calcium Carbonate: Global Industry Markets and Outlook

7 PCC production process: 2 models CO 2 Paper mill CO 2 Limestone extraction, primary crushing and screening Transport to lime kiln CaO production Transport to PCC plant Precipitation (PCC) Satellite PCC plant Lime production process PCC production process CaCO 3 -> CaO + CO 2 CaO + H 2 O -> Ca(OH) 2 Burnt lime + water -> Calcium hydroxide 7 Ca(OH) 2 + CO 2 -> CaCO 3 + H 2 O Calcium hydroxide + Carbon Dioxide -> Calcium Carbonate

11 CO2 emissions for filler PCC production process An example of emissions per tonne of FILLER PCC Quarry Drilling/blasting Crushing/sieving 2Kg CO 2 / t PCC Extracted Limestone Lime Kiln Combustion 125 Kg Reaction 440 Kg Electricity 2 Kg 567 Kg CO 2 / t PCC Transport 19 Kg CO 2 / t PCC t CaO Filler PCC Plant Electricity 37 Kg Reaction -440Kg -403 Kg CO Kg CO 2 Paper Mill CO 2 Balance for a 1 t of Filler PCC Emitted By the Quarry 2 Kg By Lime supplier 567 Kg By the Power plants 37 Kg For transportation 19 Kg Captured By Filler PCC plant Kg Total 185 Kg 11 Source: MTI

12 On-site PCC manufacturing On site PCC manufacturing reduces the CO 2 emissions : A PCC plant with tons capacity absorbs tons of CO 2 at the host mill => Total absorption CO2 in European PCC production: tons Where a Carbon Emission Trading Scheme is in place (for ex Europe), this creates a carbon credit that is trade-able: tons CO 2 Satellite uses electricity from host mill, mostly generated by using Biomass (Renewable Energy Source)

13 There is a need to look more at the total value chain: Future Opportunities arising from: Efficient (re-)use of carbon Recycling of raw materials including minerals Further integration of processes

14 Policy Recommendations How can this kind of CO 2 reduction and storage be recognized and stimulated? ETS Monitoring and Reporting Regulation (21 June 2012): Art. 49: Transferred CO 2 for CCS applications But: Recital 13: Those conditions should not, nevertheless, exclude the possibility of future innovations. What procedure to follow for having applications for CO 2 use and storage recognised in order to get a similar treatment as CCS?

15 Case of lime-based mortars: Autogenous CO 2 sequestration CaCO 3 CaO + CO 2 (Calcium Carbonate) (Lime) The European Lime Association (EuLA) estimates that 70%- 90% of CO 2 emitted during the calcination of the limestone is sequestrated again by the lime based mortar in the short term Estimated total potential of t CO 2 /year in EU-27 EuLA is further investigating Results can be shared with DG Climate Action once available.
