Chemical Fixation, Solidification of Hazardous Waste

W.E. Razzell

Dr. Wilfred E. Razzell, Director of Scientific Services, Brisbane City Council, Donaldson Road, Rocklea 4106, Queensland, Australia

Efficient, cost effective measures for the safe disposal of hazardous wastes have been developed to meet the needs of industries in Brisbane and the surrounding area. Liquid hazardous wastes are neutralised, oxidised, or reduced as appropriate, and fixed (solidified) by the addition of fly-ash and cement kiln dust to form a material of the consistency of coarse gravel. Fixation is performed in cells dug in solid clay, holding about 70 tonnes. Fixed material containing pesticides, paints or organic solvents is left in the clay cells, capped with clay; fixed inorganics and waste oils having no toxic contaminants are used for land contouring on the site. Leachate tests on the latter have been uniformly below 10 times USEPA Drinking Water guidelines - that is, 10 times better than the limits nominated by the EP Leach Test (1980). Bores around the site have detected no leachates during the past seven years. A simple but effective management system keeps wastes segregated and confirms the identity of each batch of waste on receipt. All costs are charged to the waste generator including costs of correcting errors.

Key Words: Hazardous waste • fixation • solidification • cement • flyash • leachate • management system • Australia.
