Next Generation Deicing Solutions

Succinate Based Road and Runway Deicers

2011

Renewable Chemistry Chemistry Inspired by Nature

(Formerly DNP Green Technology)

Next Generation Deicing Solutions BioAmber Inc.

Equivalent deicing performance

Succinate formulation has been AMS 1435A certified, equal to K acetate for BOD, ice melting, penetration and undercutting, freezing pt

Bio-based, Zero Carbon Footprint

Succinate deicer is made from fermentation, uses large quantities of CO2 in production, virtually colorless solution (yellow index below 6)

Competitive Price

Potassium succinate is available at price comparable to potassium acetate – and will be less expensive as KOH prices increase

Improved Corrosion Profile

Significantly better impact on materials than potassium acetate: reduced corrosion of alloys and reduced concrete scaling

Strong Patent Protection

Several patents covering production and use of succinate salts as deicing solutions and synergistic effect on freezing point
