EPA's Waste Reduction Model (WARM) Version 15

U.S. EPA Sustainable Materials Management Web Academy Webinar

Event date: 5/9/2019 12:00 PM - 1:00 PM Export event

Have you ever wanted to calculate the environmental impact of your organization's waste management practices? Have you considered making a change in how you manage your waste stream, but are unsure what the environmental impact may be? Do you have sustainability goals, but are unsure how your current waste management plan feeds into the broader goals? These are the types of questions EPA's Waste Reduction Model (WARM) can help you answer.

U.S. EPA Office of Resource Conservation and Recovery coordinates national efforts for hazardous and non-hazardous waste management. The approach to non-hazardous waste management is within the office's Sustainable Materials Management framework, where EPA works with stakeholders to limit the environmental impact of material use throughout the life cycle. One important aspect of limiting the environmental impacts is the measurement of those impacts.

WARM has been publicly available since 1998. During that time, significant improvements have been made to the tool, including the addition of new management practices and material categories. During the webinar, EPA will provide some historical background, highlight the release of WARM version 15 and walk through a practical example. Two additions in WARM version 15 are an update of the electronics category (from "personal computers" to multiple electronics categories) and estimates of the economic impact of diverting material from the landfill, which draws on EPA's Recycling Economic Information Report and other sources.

After the presentation, we look forward to answering stakeholder questions and hearing recommendations for future updates.

    Education and Outreach Tools for Your Recycling Program

    Join the Recycling Partnership “Webinar Wednesdays,” offering monthly free webinars on contamination-fighting best practices and communications tools to better your community’s recycling program. The webinars, which will be held the last Wednesday of every month at 12 pm ET, will be alternately hosted by members of The Partnership’s Technical Assistance and Communications teams.

    The webinar series will feature two “tracks” – one focused on technical assistance, the other on communications. Each track will utilize a core presentation and feature different success stories from recycling professionals across the country who have successfully implemented contamination-fighting campaigns in their community recycling programs.

    Bookmark this landing page to stay up-to-date on the webinar series: we’ll be adding in more info about which communities will be featured when, as well as specific topics to be covered in the Communications track.

    Registration is required for every webinar. Remember, it’s free! For more information visit:
