UTHealth receives $2.5 million to study metal recycling particle emissions in Houston

The Project and Partners

Metal recycling facilities accept and process scrap metals. The benefits of metal recycling over the use of raw materials include energy savings, the conservation of resources, and job creation. Yet, some recycling plants in Houston are in close proximity to neighborhoods and concerns have been raised by residents about smoke and dust. 

MAPPS is a collaborative research-to-action project of The University of Texas Health Science Center at Houston (UTHealth) School of Public Health to study and address potential health risks associated with air emissions from metal recycling facilities in Houston. In addition to UTHealth School of Public Health, other research partners include Air Alliance Houston, the Houston Health Department Bureau of Pollution Control and Prevention, and Rice University working collaboratively with metal recycling industry representatives and neighborhood residents.  


The MAPPS five-year research-to-action project will be conducted in three phases: 

Research: Conduct outdoor air monitoring, determine health risks and describe residents’ environmental health concerns
Action: Develop and apply a plan to address the research findings
Evaluation: Measure the success of our action plan
