RSustain predicts the transport and concentration of air pollutants and odorous compounds using regulatory-approved dispersion models. Our modelling supports Environmental Clearance applications, industrial licence renewals, and lender due diligence — ensuring compliance with ambient air quality standards.
We use AERMOD (steady-state Gaussian plume model) for near-field regulatory applications and CALPUFF (Lagrangian puff model) for complex terrain, coastal, and long-range transport scenarios.
