The TDJ Group is a pioneer in the development of specialty chemicals used for industrial waste stabilization. For more than 30 years, TDJ has assisted the metal casting industry (ferrous & non-ferrous), lead paint sandblasting, and soil remediation industries in the stabilization of heavy metal contaminated wastes. More than 1,000,000 tons of industrial wastes have been eliminated or safely stabilized using TDJs' chemistry, and more than 150,000,000 square feet of lead paint have been removed using TDJ chemical abrasive additives. TDJs' chemistry is the industry model for safe, cost-effective solutions for heavy metal wastes. Our management & staff possess many technical degrees including PhDs, MBAs, MSs, BSs and CPAs. However, at TDJ Group, we never stop learning, which is why we have an on-going education program for our employees. This program provides continuing education units (CDUs) in specific areas of need and encourages various industry certifications. We believe our people & products make the difference.
