What’s causing the greatest impacts

All life cycle stages

The raw material acquisition stage dominates the results, accounting for over 73% of the total impacts for nine out of ten TRACI 2.2 impact categories, followed by the manufacturing stage. For global warming, eutrophication, carcinogens, and non-carcinogens, manufacturing accounted for the second-highest contributor and over 17% of the total results. Among the raw materials, the industrial oil was the largest contributor to the total results.

Raw material acquisition

The raw material acquisition (A1) stage has the most significant contribution to most impact categories, primarily due to the industrial oil. Mastic asphalt contributes the highest weight percentage to the material composition.

Transportation

The transportation (A2) of raw materials is the least impactful contributor to the total results. Materials are sourced from within America and transported via semi-truck to the manufacturing facility.

Manufacturing

Manufacturing (A3) is the second highest contributor to most impact categories. The primary driver of environmental impacts within the manufacturing stage is the energy required to produce the product. However, impacts from the manufacturing stage dominate the results for global warming, ozone depletion, and fossil fuel depletion, stemming primarily from the use of electricity and natural gas. Activities in this stage also include final product packaging and manufacturing waste disposal.

Sensitivity analysis

Sensitivity analyses were performed to assess the robustness of the results in areas where the highest potential environmental impacts occur. Since there were two raw materials that contributed the most to total impacts, sensitivity analyses were conducted on their usage to assess the impact of decreasing their presence in these products. A sensitivity analysis assessed a 10% reduction of oil present in the product, using the Fort Worth location as a baseline.

Decreasing the amount of oil by 10% could reduce global warming potential by 4%, which shows that these products are relatively sensitive to the amount of oil present.

How we're making it greener

  • W. R. MEADOWS utilizes OEE (Overall Equipment Effectiveness) to optimize manufacturing processes and reduce energy consumption.
  • OEE identifies inefficiencies and wasted energy: By monitoring equipment performance, it uncovers downtime, slow speeds, and quality defects.
  • Energy-saving improvements through OEE: Meadows has achieved streamlined processes, better scheduling, reduced machine wear, and lower energy costs.
  • Reduction in scrap and waste: OEE insights help identify performance issues, reducing defects, delays, and material waste while enhancing product quality.
  • Supports sustainability and environmental goals: By lowering energy use and cutting carbon footprints, OEE fosters more sustainable manufacturing practices.

SM Transparency Reports (TR) are ISO 14025 Type III environmental declarations (EPD) that enable purchasers and users to compare the potential environmental performance of products on a life cycle basis. Environmental declarations from different programs (ISO 14025) may not be comparable. Comparison of the environmental performance using EPD information shall consider all relevant information modules over the full life cycle of the products within the building. This PCR allows EPD comparability only when the same functional requirements between products are ensured and the requirements of ISO 21930:2017 §5.5 are met. It should be noted that different LCA software and background LCI datasets may lead to differences results for upstream or downstream of the life cycle stages declared. LCIA results are relative expressions and do not predict impacts on category endpoints, the exceeding of thresholds, safety margins or risks. These nine impact categories are globally deemed mature enough to be included in Type III environmental declarations. Other categories are being developed and defined and LCA should continue making advances in their development. However, the EPD users shall not use additional measures for comparative purposes. Comparison of the environmental performance of water-resistive and air barriers using EPD information shall be based on the product’s use and impacts at the construction works level, and therefore EPDs may not be used for comparability purposes when not considering the construction works energy use phase as instructed under this PCR. Full conformance with the PCR for water-resistive and air barriers allows EPD comparability only when all stages of a life cycle have been considered, when they comply with all referenced standards, use the same sub-category Part B PCR, and use equivalent scenarios with respect to construction works. However, variations and deviations are possible. Example of variations: Different LCA software and background LCI datasets may lead to differences results for upstream or downstream of the life cycle stages declared.
