The North American Waste-to-Energy Conference (NAWTEC) was a leading international technical conference dedicated to the advancement of waste-to-energy (WtE) technologies and sustainable waste management practices. For nearly two decades, NAWTEC brought together engineers, researchers, policymakers, and industry professionals to present peer-reviewed research, share operational experience, and discuss innovations in energy recovery from municipal solid waste.
The conference served as a unique platform bridging science, engineering, and real-world implementation, contributing significantly to the development of modern WtE systems.

Over the course of its 17 editions, the conference documented the evolution of the sector, including:

  • Advances in combustion and thermal treatment systems
  • Improvements in air pollution control technologies
  • Development of environmental regulations and emissions standards
  • Optimization of plant efficiency and operational performance
  • Early research on alternative thermal technologies such as gasification and pyrolysis

Although the conference series concluded, its technical contributions remain highly relevant and continue to inform current practices and policies worldwide.

Many of the concepts and technologies discussed at NAWTEC have since been implemented in operational plants around the world, making the conference a key reference in the field.
