The American Reusable Textile Association (ARTA) used Environmental Clarity’s comparative LCAs to make a powerful case for washable versus single-use isolation and surgical gowns, protective garments worn by hospital personnel.
The isolation gown LCA was conducted with 24 gowns from eight suppliers representative of the overall market. The cradle-to-end-of-life analysis included all activities from natural resource extraction to manufacturing of the gowns and packaging, use and/or reuse in healthcare settings, end-of-life landfill disposal as well as laundry operations in the case of the reusable gowns. Altogether, 144 unique gate-to-gate LCIs were conducted to complete the LCA.
Environmental Clarity later examined seven reusable and 11 disposable surgical gowns representative of the market. The scope of the study covered the complete supply chain, including calculations for laundering, sterilization (if needed), and wastewater treatment operations for the reusable gowns and landfill for disposable gowns. The cradle-to-end-of-life examination required 245 LCIs.
The studies clearly showed that reusable isolation gowns and surgical gowns provide large environmental benefits versus their disposable counterparts.
Both LCAs were peer reviewed and published in professional publictions. The surgical gown LCA appeared in The AORN Journal, a journal for operating room nurses. The isolation gown LCA was published in The American Journal of Infection Control.
San Francisco–based waste solutions provider, Brightmark, needed to quantify the environmental performance of its plastic recycling technology compared to that of manufacturing plastics directly from fossil resources. Overall, our LCA found that products created through plastics recycling, like renewable fuels and wax, require only 17% of the amount of fossil fuels in the same family of hydrocarbon plastics made from virgin petroleum.
Plastic recycling was combined with the avoided waste activities to produce a cradle-to-gate impact of one metric ton of Brightmark’s total marketable products. That was compared to the cradle-to-gate impact of the virgin production required to produce the equivalent products. The the difference is the net benefit from the Brightmark process.
Overall, Brightmark’s process saved 82% of natural resource energy, 39% of carbon footprint based on U.S. waste management, 139% of carbon footprint based on regions with a 50% incineration rate, and it saved 46% in water loss.
Transparent LCI Data to Fill Data Gaps
When a Japanese government agency charged with conducting R&D to promote the country’s agriculture and food industries sought environmental LCI data for a project on crop management, it found that none of our competitors could supply the information needed.
The National Agriculture and Food Research Organization (NARO) turned to Environmental Clarity for the crop protection chemical data it required. We provided LCI data for more than eight herbicides, pesticides, and fertilizers that NARO wanted to research.
Our datasets allowed NARO visibility of the supply chains at a much higher level of transparency than previously existed and we provided process emissions throughout the supply chains, which the agency valued. One of the products for which we provided LCI data was glyphosate, the active ingredient found in the herbicide Roundup.
