Houston's #1 Recycling Challenge: Contamination
Nearly one in four items placed in blue bins cannot be recycled. Plastic bags are the worst offender—they wrap around sorting equipment, causing shutdowns and safety hazards. Never bag your recyclables; keep them loose in the bin.
Inside Houston's Material Recovery Facility (MRF)
Your blue bin contents travel to one of Houston's two MRFs, where a symphony of machines and manual sorters separate materials at 30+ tons per hour.
1
Tipping Floor
Material dumped, initial manual sort removes large contaminants
2
Screening
Disc screens separate paper from containers
3
Magnetic Separation
Steel cans extracted; eddy currents pop out aluminum
4
Optical Sorting
Air jets sort plastics by resin type
5
Quality Control
Manual sorters remove remaining contaminants
🏭 Houston's MRFs are operated by: FCC Environmental Services (North Houston) and Waste Management (South Houston). Combined capacity: 40+ tons/hour.
Where Houston's Recyclables Go
Paper
Processed into new cardboard, tissue, and office paper. Much stays in Texas.
Glass
Crushed into cullet, sold to container manufacturers. Some becomes fiberglass.
Plastics
Baled and sold to domestic and international markets. New Houston-area processors emerging.
Metal
Highly valuable; smelted into new cans, appliances, auto parts.
Market reality: Houston's recyclables are commodities. Prices fluctuate based on global demand. Despite challenges, recycling remains environmentally preferable to landfilling—each ton recycled saves 3.3 cubic yards of landfill space and reduces greenhouse gas emissions equivalent to driving 2,000 miles.
When Recyclables Become Trash
Contaminated items, non-acceptable materials, and oversized recyclables must go to landfill. For appliances, electronics, and bulky metal items not accepted in curbside bins, professional removal services ensure proper handling.
Houston recycling tip: When in doubt, leave it out! A clean, empty pizza box is recyclable. A greasy one contaminates the whole batch. Better to trash a questionable item than spoil 1,000 pounds of otherwise good recyclables.
