The Landfill and Waste Treatment Interest Group (LaWTIG)

Working together for sound waste management

About us

The Landfill and Waste Treatment Interest Groups (LaWTIG) operate under both the Western Cape and KZN Branches with the same objectives as the IWMSA.

Our mission

Our mission is to protect the environment of Southern Africa and its people against the adverse effects of poor waste management.

Our objectives

We’re committed to sound waste management through advocacy and educational activities that:

  • Encourage waste management practices that are both environmentally acceptable and cost effective
  • Promote the science and practice of professional waste management
  • Facilitate information sharing.
