The recovery, re-use and sustainable treatment (via artificial aquifers) of glycols at airports

Regulatory authorities require aircraft de-icing for safety purposes involving the use of glycol-based de-icing fluids; the raw material waste is high with a decidedly negative environmental impact. This project aims to utilize the fundamental concept of 'recover, reuse and recycle' to resolve the issue. Consequently, the project will develop and test a novel artificial aquifer at 'outside laboratory scale', whereby the residual run off from the stand areas contaminated with glycol will be degraded in an aquifer rather than discharged to sewer. This achieves a multi-functional, holistic approach to dealing with one of the most challenging environmental issues airports face.
