Delivery and Installation of the Floor Covering Delivery The product is most commonly transported by truck. For the life cycle assessment, a tonne truck with 85% utilization of its payload and an average transportation of 805 kilometers to the place of installation is assumed.

6 Installation Installation of in accordance with the Carpet and Rug Institute s Standard for Installation of Commercial Textile Floor Covering Materials, CRI For full installation instructions, see the Bentley Mills Installation Guide. The recommended installation adhesive is Bentley Mills Healthbond 2300, water based acrylic glue certified by CRI Green Label Plus indoor air quality testing program. Health, Safety, and Environmental Aspects during Installation Both the carpet and the recommended adhesives conform to CRI Green Label Plus indoor air quality testing program. Waste Waste is minimized by the modular aspect of the carpet tile. While installation waste can be sent to landfill or incineration, the preferred method is recycling through Bentley Mills Carpet Reclamation program. Contact Bentley Mills at ext or go to Packaging Carpet tiles are packaged in recycled cardboard boxes (100% post consumer recycled content cardboard). Packaging waste should be recycled through local cardboard and plastic recycling. Use Stage The product is warranted for a service life of 15 years of use. However carpets are often replaced before their service life expires due to fashion. Bentley Mills Maintenance Guidelines includes regular vacuuming and intermittent extraction cleaning. Figure 4.

8 Disposal Recycling of the product through Bentley Mills Carpet Reclamation process is strongly recommended, but disposal in municipal landfill or commercial incineration facilities is permissible in compliance with local regulations. Life Cycle Assessment General A total Life Cycle Assessment was completed in accordance with ISO / ISO Life Cycle Stages assessed: Production Stage Installation Stage Use Stage End of Life Stage Figure 5. Life cycle stages diagram

9 Description of the Declared or Functional Unit One square meter of installed carpet. The use stage is considered for one year of service life. The reference flow is one square meter of carpet. Cut-off Criteria The cut-off criteria established for the study include or exclude materials, energy and emissions data. For the purposes of this study, the criteria are as follows: Mass If a flow is less than 1% of the mass of the modeled product it may be excluded, providing its environmental relevance is not a concern. Energy If a flow is less than 1% of the cumulative energy of the model it may be excluded, providing its environmental relevance is not a concern. Environmental relevance If a flow meets the above criteria for exclusion, yet is thought to potentially have a significant environmental impact, it will be included. The total excluded flows do not exceed 5% of overall life cycle. Allocation Where relevant, the background data incorporates some allocation as in the power mix, where possible appropriate geographical grid mixes were used. No upstream impacts were allocated to recycled materials Background Data GaBi 4 software system was used for modeling the life cycle of the modular broadloom carpet Data Quality For the data used in this LCA, the data quality is considered to be good to high quality. The definition of this quality range stems from the following descriptions. The data and data sets cover all relevant process steps and technologies over the supply chain of the represented carpet products. The LCIs from the GaBi 4 database and Plastics Europe are mainly based on industry data and are completed, where necessary, by secondary data. The operations data is representative of a sufficient sampling over and adequate period of time. The temporal correlation falls under a three year window for the vast majority of data considered. The geographical correlation is slightly challenging as there is very little life cycle information available that is country specific in every facet. For Bentley Mills, there is a reliance on data produced from European sources with country specific considerations during the LCI creation. Given that the data is from similar production conditions and representative of the technology and production paths used by Bentley Mills direct suppliers, this is acceptable to Bentley Mills and deemed to have an appropriate level of quality. A possible source of uncertainty from geographical sources is the incorporation of European electricity grid mixes into many of the LCIs that are used.

10 System Boundaries The Life Cycle Assessment includes all relevant cradle-to-grave environmental information for one square meter of carpet. The system boundaries include raw material production and processing, carpet manufacturing, energy production, packaging, transportation, carpet installation, use and maintenance, as well as the end-of-life options (recycling, incineration or landfill disposal). Notes on the Use Stage: The warranted service life of the product is 15 years. The use stage includes both vacuuming and extraction cleaning according to the maintenance guidelines of the Carpet & Rug Institute and accounts for the electricity, water, and cleaning agents consumed. The use stage impacts have been annualized. Life Cycle Inventory Analysis The total primary energy for the product can be separated into life cycle stages and the energy for the production stage can be further separated into the energy from primary (virgin) materials, secondary (recycled) materials, and process energy. Figure 6 shows the primary energy from both renewable and non renewable resources for products with low (576 gram), medium (1017 gram), and high (1492 gram) yarn weights. Figure 6.

14 Non-renewable material resources, water consumption and wastes The life cycle of the product consumes non-renewable resources and water while producing non-hazardous, hazardous, and radioactive wastes. The quantities, separated into contribution per life cycle stage, are shown in Figure 12 for a medium yarn weight product. The total amounts for low, medium, and high yarn weight products are shown in Figure 13. Figure 12.

Ninety percent of the Global Warming Potential occurs in the production stage and 57 of the 90 percent is attributed to the raw materials. Another major contributor to impacts is the dyeing process which is energy intensive. Process energy contributes 33% of the Global Warming Potential. Bentley Mills will continue to increase the level of recycled content in carpet with the intent of eventually eliminating the use of virgin materials and decreasing environmental impacts. Installation which includes adhesive and cutting waste contributes generally less than 1 percent to the impacts. The use stage is represented in this report for one year of maintenance. The yearly contribution to the life cycle impact is small. Over the expected life of the carpet the contribution of the use stage increases. The end of life stage has minimal impact (8% of GWP) because in the model, the used product is sent to landfill. Every effort is made to insure the product is returned to Bentley Mills for recycling, but the use of the returned carpet in other types of carpet and other materials precludes modeling a recycled end of life. The carpet reclamation program is an extensive reclamation and recycling program that recovers both yarns and backings from post consumer and post industrial carpet and the program reclaimed over 1100 tonnes of carpet in This was on sales of over 3.2 million square meters of carpet or approximately 11 percent by weight.

18 Bentley Mills and its stakeholders share a common concern for the environment with particular interest in mitigating climate change through the elimination of product-related emissions. They have addressed this concern by creating climate neutral products. The total GHG emissions created during the life cycle of the products (raw material acquisition, manufacturing, transportation, use and maintenance, and end-of-life disposition) are modeled using Life Cycle Assessment methodology. These emissions are then neutralized through the purchase and retirement of an equivalent number of verified emission reduction credits. As a result of this program, Bentley Mills product offering is climate neutral. This program is verified by SGS. Additional Information, Evidence, and Test Results Emissions Low VOC emissions are documented by CRI Green Label Plus certification through testing at Air Quality Sciences, certificate #5410.
