• Transparency, credible and science based
• Inform a manufacturer’s decisions for design, supply chain modifications, material selection, performance improvements, end of life options
• Provide a means to track incremental improvements in the products’ sustainability profile
• Comparison of products that provide similar function
• Address more than environmental and human health impacts – includes Social Responsibility

Product Design
• What chemicals of concern are in typical products? Or packaging?
• Inventory of all materials at or above 1000 ppm of product
• Effort to reduce or eliminate chemicals of concern
• Supplier of materials – elimination or reduction of chemicals of
concern

(EPDs) and USEPA’s Design for the Environment (DfE) – Are these
appropriate for the industry?
• Environmental considerations in design of product

Material Selection
• Inventory of materials and chemicals of concern– 1000 ppm for hazardous chemicals– 10,000 ppm for other ingredients
• Environmentally sustainable inputs– Product– Packaging
• Chemicals of concern– Reduction– Elimination
• Material safety according to NSF drinking water standards– DWTU and DWA
• Suppliers criteria
![Page 9: Overview of the NSF 375 Draft Sustainability for the Water Treatment and Distribution Industry October 30, 2012](https://reader036.vdocuments.net/reader036/viewer/2022070410/56649f145503460f94c28512/html5/thumbnails/9.jpg)
Life cycle analysis and Design for the Environment
• Environmental considerations in design– Environmental assessment program for product design and
development• LCA or DfE
– Design for the Environment assessment of the product– LCA using ISO 14040/14044 with 5 impact categories
• Life cycle assessment improvement– Using the LCA, show improvements in 2 impact categories
• Contributing to US Life Cycle Inventory– In an effort to show support, data is supplied to the USLCI
database for LCA• Environmental Product Declaration (ISO 14025)
– A product category rule must exist in order to pursue an environmental product declaration

generated, carbon credits, green-e certificates, others
• Water use during manufacturing, water quality discharge
• Waste minimization, optimal use of resources, packaging
• GHG emissions, air resources protection, PBT reductions
