At Weingarten shopping centers, recycling has been primarily focused on the waste stream from our tenants and shopping center visitors. This was primarily limited to cardboard, aluminum cans, plastic, glass, etc.; basically the same items you may set on your curb for a neighborhood recycling program. While this is a very important side to a successful recycling program, we wanted to maximize our commitment to recycling at more levels. Starting in 2012, we made an effort to start recycling non-traditional items related to our capital projects, mainly parking lot and roofing debris, and track that information. Much of this material would have been dumped in landfills if not for our efforts.
On roofs, there are some types of single ply membrane that are candidates for recycling. Any ballasted or mechanically attached single ply can be recycled. Additionally, all the gravel from all the Built Up and Ballasted roofs can be repurposed (landscaping and road base). Some insulation (polyisocyanurate and expanded or extruded polystyrene) that was not mopped or glued can be recycled. Lastly, all roofs have some old sheet metal (counter flashings, edging, gutters, etc.) that get replaced. Working with different vendors, we were able to recycle most if not all of these qualifying materials.
• 9 roofing projects with gravel = 1,807 Tons
• Scrap Metal = 123 Tons
• 1 Insulation (EPS) project recycled = 9.2 Tons
• 5 single ply membrane projects recycled = 92.35 Tons
• Cardboard = 5 Tons (boxes and paper stock inside of single ply rolls)
• #2 Plastic buckets = 2 Tons
On parking lots, we worked with our vendors to ensure spoils were recycled and not just sent to a dump or fill site. Asphalt paving and the associated base is sent back to the asphalt plant to be reused in new mixes. Concrete is sent to a crusher who repurposes it in various aggregate needs.
• Concrete – 1,036 Tons
• Asphalt Paving and Base – 6,004 Tons
This initiative to recycle non-traditional materials and track the data resulted in a total of 9,078.55+ Tons of material that was diverted from landfills. By requiring vendors to take these steps, plan for recycling, and report the data back to us, we were able to capture this information. Our commitment to further expand and track the recycling to these areas sets Weingarten apart from many other companies.
