Curbside recycling does not go straight to a factory. It travels through several processing steps before any material actually gets reused, and what happens at each step determines whether your effort at the bin actually counts.
Step 1: Collection and Transport
Recyclables are collected on the same geographic route logic as regular trash but hauled by a dedicated truck to a separate facility. In single-stream programs, all recyclables go into the same truck compartment and are separated later at the processing facility. In dual-stream programs, fiber (paper and cardboard) stays separate from containers (cans, bottles, plastic) from the moment of collection.
Most Orlando-area residential programs run single-stream collection, which is more convenient for residents but places a greater burden on downstream sorting technology to separate materials accurately.
Step 2: Sorting at the MRF
The truck delivers its load to a materials recovery facility (MRF). At a modern MRF, the sorting process combines mechanical screens, optical scanners, magnets, eddy current separators, and manual sorting to pull the mixed load apart into separate commodity streams: cardboard, mixed paper, aluminum, steel, and multiple plastic resin grades.
The equipment used at MRFs has grown significantly more sophisticated since the 1990s. Britannica's article on recycling describes how optical sorting technologies now identify and separate plastic types automatically at high speed, something that previously required slow manual sorting.
Step 3: Baling and Commodity Markets
Sorted material is compressed into dense bales and sold to processors that convert it into raw material: cardboard into new cardboard, aluminum back into sheet aluminum, and certain plastics into fiber or packaging material. The price facilities receive for each material type fluctuates on commodity markets, which means recycling economics are tied to global demand for secondary materials in ways that most curbside users never see.
This commodity market dependency is one reason recycling program economics can shift quickly. When markets for certain plastics collapsed in 2018 after China restricted imports of recycled material, many U.S. programs had to reduce what they accepted or pay to dispose of material they previously sold. Wikipedia's article on China's National Sword policy explains that event and its lasting effects on U.S. recycling programs.
Why Contamination at the Bin Matters Downstream
A single out-of-place item typically does not ruin a load. The problem is when contamination is widespread enough that an entire bale cannot be sold to a processor and gets diverted to a landfill instead. This is why sorting correctly at your bin, as covered in our guide on the Orlando trash and recycling pickup schedule, has real downstream consequences and is not just a feel-good exercise.
Plastic bags are the single most common contaminant in single-stream programs. They wrap around sorting machinery belts and must be removed manually, slowing the entire facility. Bags go in the trash or back to a grocery store bag return, not in a curbside recycling bin.
What Does Not Go Through This System
Yard waste, construction debris, and hazardous materials are handled in entirely separate streams. If you have a large amount of material that does not fit cleanly into a curbside bin, our waste management service and container rental options are built for that situation.
