Narrative Description of the Impact Areas Targeted for Reduction (must include specific steps, dates, and timeline for completion, and include why/why not GWP is targeted for reduction and include a numeric impact reduction target. Actions must correspond to impact modules analyzed in the LCA or EPD):

The results for the Mid-Weight Gypsum Finishing Compound produced at the Calgary, AB plant, show that the packaging of the product accounts for 20-40% of the overall environmental impacts in 5 of the 6 TRACI environmental impacts reviewed in the study. Further analysis shows that the pails used in the packaging account for the largest impact component for these impact categories. BCD Gypsum Company has developed an action plan to reduce the overall life cycle impacts of the Mid-Weight Gypsum Finishing Compound by changing the packaging from the plastic pails to cartons made from recycled material which will result in a 20% impact reduction of GWP. Study of the product shows that this change in packaging has no impact on product quality and continues to promote recycling of product containers after the product is used. This action plan includes the following steps for anticipated completion by November 2022:

Addendum to LCA Report: Action Plan for Impact Reduction

This life cycle assessment (LCA) was conducted for the Light Weight and Mid Weight Finishing Compounds produced by BCD Gypsum company Calgary, AB. This report is compiled in accordance with the EN 15804 Standard and the Product Category Rule (PCR) for Building-Related Products and Services: Part A-Calculation rules for the Life Cycle Assessment and requirements on the Project Report. The results will be published in accordance with the EN 15804 standard and the PCR Guidance-Texts for Building-Related Products and Services: Part B-Joint Compound EPD Requirements. This work was completed by the Sustainability Department of BCD Gypsum Company.

For this life cycle assessment, the BCD Sustainability Department collected specific data on energy and material inputs, wastes, water use, and transportation impacts for the Calgary, AB manufacturing plant. The data used was for calendar year 2016. Production data was used to allocate these inputs and wastes to the functional unit of 100m2 of covered substrate considering an installation scenario as defined by a GA-214 Level 4 finish with the quantity adjusted for the measured shrinkage with a service life of 75 years.

GaBi 8.2 software was utilized for modeling the complete cradle-to-grave LCI for this study. Both primary and secondary LCI and metadata are used throughout the study. All secondary data is taken from literature, previous LCA studies, and life cycle databases. The Ecoinvent v3 (http://ecoinvent.org/), US-Ecoinvent v2.2 (www.earthshift.com), and US LCI (www.nrel.gov.lci) databases are used in this analysis frequently and contain thousands of processes for material, processing, energy, and transportation. These databases are critically reviewed and require a paid license.



Impact Areas Targeted for Reduction – Calgary, AB

An analysis of the life cycle results for the average Mid Weight Gypsum Finishing Compound produced at the Calgary, AB facility, indicates that the packaging used at the end of the manufacturing process accounts for most of the manufacturing Global Warming Impact Potential impacts, as well as 20-40% of four more impact categories, as seen below in Table 7.8 and Figure 7.15. Further analysis indicated these impacts are associated with the plastic pails used in the packaging, seen below in Figure 7.11. The targeted area for the reduction of impacts is identified as the packaging, with an emphasis on the pails, by replacing the pails with cartons which are lighter weight and made from recycled material.



Table 7.8: Overall Environmental Impact Potentials for BCD Finishing Compound – Calgary, AB (per 100m2 coverage)

Table 7.15: Overall Environmental Impact Potentials for BCD Finishing Compound – Calgary, AB (TRACI 2.1, 100m2 coverage)



The charts below show the potential decrease in environmental impacts that could be realized by replacing the plastic pails with cardboard cartons. The three charts analyze Global Warming Potential (GWP), Acidification Potential (AP), and Eutrophication Potential (EP).

Table 7.11: Environmental Impact Potentials for Packaging of BCD Finishing Compound – Calgary, AB (TRACI 2.1, 100m2 coverage)



The action plan for the replacement of the plastic pails is outlined below in Table 7.9. A gradual phase out of the plastic pails will begin immediately with targeted complete phase out by December 2019. In order accomplish this, the supplier of the cardboard cartons will need to be contacted to increase the order of the cartons to replace the pails. After complete phase out of the plastic pails is accomplished, the plant can begin to decommission the packaging equipment that was specific to the pails. Finally, the business will follow up with a customer feedback survey and updated study on the impact reductions.
