Alternatives Assessment Considerations for the Analysis of Engineered Nanomaterials

Introduction

Mitigating the impact of toxic chemicals on human health and the environment requires an informed transition to safer alternative chemicals, materials, and technologies. Alternatives assessment is a multi-disciplinary approach to support informed substitution and is defined as a “process for identifying and comparing potential chemical and non-chemical alternatives that could replace chemicals of concern on the basis of their hazards, performance, and economic viability” (National Research Council, 2014).

Addressing Microplastics in Alternatives Assessment

Introduction  

Supporting the transition to safer and more sustainable chemicals and materials requires minimizing the chance of a regrettable substitution. Alternatives assessment is defined as a “process for identifying and comparing potential chemical and non-chemical alternatives [e.g., materials, products, technologies] that could replace chemicals of concern on the basis of their hazards, performance, and economic viability” (National Research Council, 2014).

Alternatives Assessment Criteria for Hazard Evaluation

The Design for the Environment (DfE) Program at the U.S. Environmental Protection Agency developed the Alternatives Assessment Criteria for Hazard Evaluation as a transparent tool for evaluating and differentiating among chemicals based on their human health and environmental hazards. The Criteria are applied in all of DfE Alternatives Assessments and can be used by other organizations.

To ensure that the Criteria remain relevant and useful for distinguishing among chemicals, DfE may update criteria based on experience conducting alternatives assessments and on stakeholder input.

GreenScreen® for Safer Chemicals® Methodology

GreenScreen for Safer Chemicals® (“GreenScreen”) is a chemical hazard assessment methodology. 

The guidance provided in this publication clearly outlines every step for performing GreenScreen assessments, including how to assess and classify hazards, derive GreenScreen Benchmark™ scores and GreenScreen List Translator™ scores, and make informed decisions.

Guidance on Key Considerations for the Identification and Selection of Safer Chemical Alternatives

This guidance was developed with the aim to advance broader agreement on a general approach and criteria for the selection of safer alternatives, with a focus on chemical substitution. It is intended to advance a consistent understanding of the minimum requirements needed to determine whether a chemical alternative is safer than the priority chemical, product, or technology for substitution, independent of the entity performing the assessment or the alternatives assessment framework being used.
