Wisconsin has been a leader in hazardous waste minimization and management programs. The DNR Green Tier Program is a nonregulatory voluntary program to support businesses, local governments and communities. Wisconsin generates 4.6 million tons of MSW, most of which is landfilled, and recycles more than the national average. Join ASCE-WI and LWVWI on February 6, 2025 from 12:00 to 1:30 pm to learn more about Hazardous Waste (B) & Solid Waste (B) management in Wisconsin.

This is one webinar in a nine-part series looking at the state of all areas of infrastructure in Wisconsin.  Learn about the whole series: Back to the 2024 Report Card for Wisconsin's Infrastructure series page
