The company also operates Mainstream Recycling, a wholly-owned circular-economy subsidiary with resource-consented facilities achieving up to 98% waste recovery rates, and has completed technical milestones including the world's longest submerged sonar inspection (2.4 km) in 2013 and again in 2023. TDG holds ISO 9001, ISO 14001, and ISO 45001 certifications.
