deb8f616-d451-4904-b241-d7295713accfPCC slurryPrecipitated Calcium Carbonate (PCC) - slurry, uncoated, with a solid content ranging from 15% to 40% in the slurry, a CaCO3 content of 98% or more, a median particle size ranging typically from 0.3 to 3 µm, ready to be shipped as slurry. Production at plant.Production at plantnonePCC slurryProcessesProcessesEESACPCCSpecific data collection and process modelling were performed in accordance with ISO 14040 and 14044 series. Process related data were collected on 14 PCC production sites located in 7 European countries + Norway + Turkey. The data were then consolidated by process stage (horizontal aggregation). The resulting LCI calculation is based on the PCC slurry production process route and corresponds to generic industry screening results. The electricity model used for the project is representative of the average production of the 27 European countries + Norway + Turkey. Other upstream data are based on European averages. For modelling and other upstream processes and materials, the Gabi 6.3.1.14 (PE International) database was used whenever possible and the Ecoinvent 2.2 database as second choice. The Gabi 6.3.1.14 software has been used to generate this ELCD data set for PCC slurry.106107The data set is based on average site-specific data of the PCC plants located in the EU(28), Norway and Turkey. Electricity grid mix is an average of electricity produced in EU(27), Norway and Turkey. Other upstream data are based on European averages.Precipitated Calcium Carbonate is made by direct carbonation of milk of lime. The milk of lime is produced in the PCC plant from quicklime. Waste gas from paper mills, power plants or lime kilns is usually used as the main source of carbon dioxide. Following the carbonation / precipitation step, the PCC slurry undergoes sometimes a thickening step before being delivered.PCC slurry is used as filler in:
- filler or coating agent in paper
- filler in polymersPCC slurry - Process flow.jpgLCI resultAttributionalNoneAllocation - massTwo cases: sites without by-product: 100% allocation to main product / sites with by-product: mass allocation (considering dry matter)For the mass balance, separate flows were used to model dry matter and water in the product.NoneProcesses and activities that only constitute a negligible contribution to the data collection were excluded using one of the following criteria: together they contribute to less than 1% of the total environmental impact for each impact category and/or b. they represent less than 1% of the mass input. All upstream processes (electricity, etc.) are included. Infrastructure is not included.NoneThe ELCD Dataset is based on average site-specific data collected on 13 sites using technologies which are representative for the PCC slurry production in Europe + Norway + Turkey. To generate the European + Norwegian + Turkish typical values, a horizontal aggregation was used, i.e. an average was calculated for every process stage (e.g. quarry, transportation, crushing, blending etc.). At least 4 sites are used for every process stage. The general procedure adopted during the project for data collection and LCI calculation was: 1. Collect information from the selected sites, per process stage. 2. Aggregate these individual information per process stage, using an horizontal aggregation method 3. Calculate the LCI of PCC slurry, based on the process route detailed in the enclosed figure.NoneMissing data are substituted by the average value calculated from the data supplied by those plants that made positive returns.NoneGaBi databasesEcoinvent Database97.0Selection of sites for the reporting of process data based on a preliminary survey among all CCA members2012-2013"The data set is a cradle to gate life cycle analysis of PCC slurry. The LCI data set should be used for LCI/ LCA studies where PCC slurry is used. The transportation of PCC slurry from the PCC plant and any further use has to be taken into account additionally since the data base on a cradle-to-gate approach. Disclaimer: Being average figures, the LCI data provided in this datasheet are representative of the PCC slurry production as a whole. It is to be noted that in some cases site specific values may vary on some flows compared to the figures here enclosed.
