Bellaire ESB hosts Waste Management briefing on recycling, contamination and safe disposal

The City of Bellaire Environmental Sustainability Board (ESB) hosted a public learning session on recycling in which Waste Management senior account Shanna Lopez described how material-recovery facilities (MRFs) sort recyclables, the limits of domestic markets, and items Bellaire residents should not place in curbside bins.

The presentation matters because contamination and hazardous items in curbside recycling affect whether loads are saleable, raise collection costs and can cause fires. Lopez said Bellaire's recent audits show relatively low contamination but urged residents to follow simple rules so local recycling remains viable.

Lopez opened by describing the circular goal for recyclables: "We want to make sure that that plastic water bottle that we can take in is gonna become something else," she said, explaining that end markets must exist for a collected material to be recyclable in practice. She showed video and slides depicting the MRF process: trucks tip material onto a floor, conveyors and human sorters remove tanglers (bags, Christmas lights, batteries) and optics then separate aluminum, plastics, paper and cardboard into commodity bales.

Lopez described major operational changes at MRFs: fewer people physically sort material (she said one facility reduced from about 30 sorters to roughly 11) and companies have invested in optical sorters and other automation. She said waste-management companies and mills have shifted much of…
