Alternative Aircraft Anti-Icing Formulations with Reduced Aquatic Toxicity and Biochemical Oxygen Demand

The current research was conducted to identify alternative aircraft and pavement deicer and anti-icer formulations with improved environmental characteristics compared to currently used commercial products (2007). The environmental characteristics of primary concern are the biochemical oxygen demand (BOD) and aquatic toxicity of the fully formulated products. This current report presents the results of the second phase of the research, wherein candidate alternative components were evaluated and mixtures were built up through a progressive series of performance and environmental testing and down-selecting. At the direction of the research panel, the research objectives in this phase were the development of a Type IV aircraft anti-icing fluid formulation with reduced toxicity compared to commercially available products, and identification of an additive for solid pavement deicers to reduce caking. Section 1 of the report contains background information. Section 2 presents a summary of the rationale for the selection of alternative candidate aircraft and runway deicing/anti-icing components evaluated in the test program. A summary of the test plan used to evaluate the alternative components is presented in Section 3. The test program was divided into two parts: Tier 1 and Tier 2. Details of the Tier 1 experimental results are presented in Section 4 and the Tier 2 results in Section 5, including a summary of the aquatic toxicity results for the final Type IV formulation. Degradation pathways for the deicing components are detailed in Section 6. Conclusions of the study are presented in Section 7, and suggested future research topics are provided in Section 8.
