About Fourth and Glass

Why "Fourth and Glass"?

Fourth and Glass Recycling Co. was founded by Alex Stiles, a recent graduate from the University of Tennessee and former resident of the Fourth and Gill neighborhood that is the namesake of our company.  He loved the feeling of community in this neighborhood, so it was a natural fit as the first collection location.  Of course, there is a need for more glass recycling options all across Knoxville, and we are expanding our service to include as many neighborhoods as possible!


Alex Stiles, PhD

Owner/Glass Tinkerer

Alex has a PhD in Energy Science and Engineering and a BS in Mechanical Engineering.  While he may have finally found his calling driving a glass collection route, he's also working to develop the next generation of 3D printing technology using - you guessed it - recycled glass.  This research began when Knoxville dropped curbside glass collection in part due to low scrap value and a lack of local markets for glass waste.  Alex has travelled the country to learn how other cities are addressing their glass waste issues, which is why we are now tackling the problem head on by starting our own glass collection service.  You can learn more about future uses for glass waste at our sister company, Vitriform3D.  


Mandy Tietjen

Operations Manager

Mandy is passionate about making Knoxville a great place to live. Whether through volunteering as a member of Hard Knox Roller Derby with local charities (Mobile Meals, Chain Free Knoxville, Sunshine Ambassadors, Knox Pride, etc.) or her work with youth in local learning cooperatives, Mandy enjoys interacting with the community, and aims to leave everywhere she goes a little better than when she found it. She may not know how to operate the glass crusher just yet, but it’s only a matter of time. Until then, you can find her collecting, sorting, and preparing your glass recyclables.
