Sample text

The chemical alternatives assessment framework should encourage innovation in chemical and process design to meet a particular chemical function for situations in which no alternatives are available, the currently improvements in the original areas. This approach might limit the adoption of incrementally better alternatives that could act as interim solutions while better solutions are developed. These situations could be handled on a caseby-case basis as long as the acceptance of such an interim solution is consistent with the entity’s values.

This can be done by incorporating different alternatives over part or all of a product’s life cycle and estimating the broader environmental impacts associated with these flows. Use life cycle assessment methods to assess potential social and socioeconomic impacts of each alternative over its life cycle. Inputs: List of alternatives from Step 7 and result of Life Cycle Thinking (Step 8). Outputs: Assessment of the relative life cycle impacts of alternatives. Frameworks: BizNGO and IC2 Broader environmental impacts of alternatives can be informed by comparing the life cycles of the alternatives and their implications for how alternatives differ in resource consumption and materials emitted.

When initial screening is used in an assessment, care must be taken to ensure that overly conservative predictions of alternatives’ performance do not lead to the elimination of potentially viable alternatives that could be further developed to meet technical and economic goals. STEP 4: DETERMINE IF ALTERNATIVES ARE AVAILABLE; REFER CASES WITH LIMITED OR NO ALTERNATIVES TO RESEARCH AND DEVELOPMENT Goal: Initiate research to develop new alternatives or improve existing ones when no (or limited) alternatives are available.
