Heat generation for clinker production
General comment on data set Industrial burner used to burn coke and convert solid waste into heat generation for using in a cement kiln in Brazil, northwest region. The studied cement kiln produces 70-90,000 t/year of CP-II-Z-32 and CP-II-F-40 cement types.

Time representativeness
Data set valid until 2017
Time representativeness description Primary data was collected from one cement kiln in Brazil from 2016-2017. Technical visits by using semi-structured questionnaries were designed to collect data at the company, and also secondary data from LCA databases and literature was adopted when primary data was not avaiable.
Technological representativeness
Technology description including background system Tecnology level was limited to the co-processing of wastes for heat generation at a cement kiln. Thus, the system modelling was a gate-to-gate approach. A variety of wastes can be used as fuel to generate heat, since biomass, oil, industrial waste and other renewable and non-renewable energy sources. Waste is selected in order to avoid sulphur and chloride co-processing emissions that affect clinker and cement quality and also can cause environmental impacts. Ash and moisture content are also common parameters used to select waste for co-processing. The lower the sulphur, chloride, ash and moisture content, the better the waste quality.

Type of data set LCI result
LCI Method Principle Other
Deviation from LCI method principle / explanations Attributional approach
Modelling constants The LCI is entirely done with an attributional methodology. No allocation or substitution methods have been considered in the process.
Data sources, treatment and representativeness
Data cut-off and completeness principles It was assumed 1 % of the total mass and energy of material resources consumed as cutoff criterion for the dataset construction.
Deviation from data cut-off and completeness principles / explanations None.
Data selection and combination principles All the input/output data was collected for the Brazilian Northwest region as it accounts for more than 50% of the national production of cement in the country. Data for one company, located in the State of Ceará was collected (70-90,000 t of cement/mont in 2016).
Deviation from data selection and combination principles / explanations None.
Data treatment and extrapolations principles Primary data was collected directly at the company based on questionnaries application and analyzes of raw material consumption and waste generation statistcs and reports. Technical visits were schedulled for data caollection. After that, all input/output data was treated in terms of consistency content and for calculation of average, standard deviation and adapt flows to the LCA Reference Flow. See also 'General information' section for more details.
Data source(s) used for this data set
Sampling procedure The data was collected during 1 year of sampling between 01/2016-12/2016. Abrupt variation of input/outputs measurement and calculations were excluded due to statistical reasons. See also 'General information' section.
