Brooke Marten is engineering a better environment through high tech solid waste analysis.

Marten just completed her PhD in environmental engineering, focused on what happens to trash after it is carted off to the landfill – and ways to turn it into a valuable product.

U.S. News and World Report’s Best Graduate Schools rankings for 2025 are out, and the CU Â鶹ӰԺ Environmental Engineering graduate program is #7 among public universities.

A CU Â鶹ӰԺ-led team has received a $650,000 grant to measure and mitigate pollution in the Cache la Poudre and Yampa Rivers in Colorado through new sensor technology, monitoring, and a voluntary carbon credits trading system with industry.

Engineers at CU Â鶹ӰԺ are investigating whether improving classroom air quality with air purifiers can help students miss fewer school days.

The study comes at a time when millions of students across the country are chronically absent from school, a worsening trend that could have large impacts on students’ academic performance.
