TOUR CANCELLATION: The City's Recycling Branch will be cancelling all Tour de Trash excursions for 2020.

Subscribe to Wasteline e-newsletter to recieve tour information. 

  Our tours are a great way to learn more about how the City and County of Honolulu manages our island’s Municipal Solid Waste (MSW) and how businesses are implementing sustainable practices while providing crucial services and products.

The City faces challenges in waste management and needs to be knowledgeable in determining future directions.  On an island, land is one of our most precious resources, and reducing the use of landfills is a critical goal of the hierarchy of waste management.  In order to move forward successfully with major source reduction and recycling initiatives and alternative technologies, it’s imperative that we engage the public in intelligent discussion.  Raising public awareness of our `ōpala, through Tour de Trash, Opala.org, and other educational outreach programs helps to facilitate better public discussions and decision-making on source reduction, recycling, and waste management initiatives.

Tour De Trash enables the public to see firsthand, the processes involved with managing MSW to include source reduction, recycling, composting, waste-to-energy, and landfill diversion.  The City’s Department of Environmental Services’ Tour de Trash focuses on public outreach and partnerships to protect O`ahu’s environment for future generations.

Tour de Trash 2021

The City is looking forward to providing the following upcoming tours beginning April 2021 to celebrate Earth Month.  Subscribe to our “WasteLine” newsletter to get up to date information about the upcoming tours listed below, our bi-monthly podcast “ENV Matters” and informative articles about how waste is managed on Oahu and issues that affect our island home.”
