A method and a system for recycling spent ethylene or propylene glycol recovered from aircraft deicing solutions is described. The recovered spent ethylene or propylene glycol contains water and other undesirable substances which require to be removed to produce a solution free of these substances which can be further processed to remove substantially all of the water content and to blend-in additives required to certify the final glycol solution for aircraft deicing. The method and system employs a computer controller for continuous automatic batch processing of the spent glycol, including, in combination, filtering, distillation, blending and testing in specific sequences and achieves an improved quality recycled glycol of a purity of at least 99.5% and preferably between 99.6% to 99.9% glycol concentration.
