Lifecycle inventory for lime
In order to provide reliable data for lifecycle assessment (LCA), Environmental Product Declarations (EPD), and other sustainability initiatives, the European Lime Association (EuLA) commissioned a lifecycle inventory (LCI) for quicklime and hydrated lime. The 'Cradle to Gate' inventory provides a valuable information source for downstream product users who want to carry out lifecycle assessment of their products.
The EuLA LCI is based on production data from 2015 and covers more than 84% of all lime production in Europe. It is the most representative LCI available on lime and has been shown to meet the requirements of an independent external review.
LCI data for LCA can be requested from EuLA via the webform available here.
EuLA has also produced a summary of the findings.
The inventories were developed using methodologies that are compliant with ISO 14040 and ISO 14044.
EuLA commissioned an independent third party, EESAC, to conduct the LCI study.
Manufacturing lime plants in Europe provided data on material inputs and environmental outputs, including the use of natural resources, the consumption of water and energy and the emissions to air and water.
These data were rigorously cross-checked for accuracy and consistency by EESAC and were used to calculate European averages used in the study.
The final LCI was subject to independent external critical review performed in accordance with ISO 14040-14044 by RINA Consulting. A copy of the critical review is available here.
The study covered the production of quicklime and hydrated lime 'from cradle to gate', i.e. beginning with the extraction of raw materials from the ground (the 'cradle'), to the finished products, ready for shipping at the gate of the production plant. As lime is used in a diverse range of end markets, it is not possible to undertake 'cradle to grave' analysis – that is, the whole life-cycle. However, the LCI provide the information needed for product users to undertake such 'cradle to grave' analysis.
The data were collected for the three main process steps consisting of quarrying, calcination and hydration. The results of the LCI covered 99% of all environmental impacts of the lime production process.
One tonne of quicklime and one tonne of hydrated lime were used as reference units to which all derived figures were compared. The data is representative of the production conditions prevailing in the EuLA member companies across Europe.
The Safe Handling of Lime document (available here) gives some general guidelines on the handling requirements for lime products.
However, please refer to the supplier's Safety Data Sheets for the complete safety information referring to an individual product being considered.
