Trinity Consultants Australia was engaged to deliver comprehensive air quality, noise, and greenhouse gas assessments for the entire mining and mineral processing operation. The team conducted collaborative workshops with the client’s process engineers to fully understand emissions sources, reaction chemistry, and potential abatement strategies, including innovative mineral processing methods and H₂SO₄ production by elemental sulfur burning.

A complete carbon footprint was prepared covering Scope 1 direct emissions, Scope 2 purchased energy, and Scope 3 transport emissions. The assessment included four abatement scenarios, one of which targeted carbon neutrality. Trinity then developed site-specific Air and Noise Management Plans detailing measures to control impacts, such as reducing nighttime activities near sensitive homesteads, designing proactive monitoring programs, and implementing source controls on roasting and de-ammoniation plants.

To support ongoing compliance, Trinity installed high-volume and low-volume air samplers, meteorological stations, dust gauges, and third-octave noise monitoring stations. Local staff were trained in their use to ensure reliable data collection and robust environmental performance.
