NYC Pilot Uses 10,395 Pounds of Plastic Waste in Staten Island Asphalt, Cuts CO2 by 16,128 Pounds

New York City tested recycled plastic in asphalt on two Staten Island streets in 2022. The pilot used 10,395 pounds of plastic waste to replace part of the bitumen binder in four test sections on Rice Avenue and Royal Oak Road. The city says the plastic-modified pavement cut carbon dioxide emissions by 16,128.2 pounds compared with conventional asphalt. Researchers at Rutgers are monitoring the roads for cracking, rutting, and microplastic release. The NYC Department of Transportation is treating the project as a test, not a final answer. Wider use would depend on long-term durability, consistent plastic feedstock, and worker safety, according to industry groups.

Neat pilot. 10,395 lbs of plastic waste went into asphalt on Staten Island, with Rutgers tracking durability and microplastics. The carbon number is small but the idea matters if it scales across NYC's million tonnes of asphalt per year. Worth watching the long term data.

The 16,128.2 lbs CO2 savings looks precise but it's a pilot scale number. The real question is whether the plastic modified asphalt holds up and doesn't shed microplastics. If it does, it gives hard to recycle plastic a use and cuts bitumen demand. Good to see the city didn't just take the manufacturer's word.

One thing I want to see is the dosage levels and the performance data from Rutgers. Plastic waste isn't one material, so different feedstocks will behave differently. Also the CO2 savings depend on how much bitumen is replaced. If it's only a small percentage, scaling to all million tonnes still needs a lot of plastic and steady supply.

This is the right way to test a material: real roads, side by side, with independent researchers. But wider use will need standards for plastic feedstock and worker safety, not just emissions math. NYC DOT calling it a test project is the correct stance until the pavement proves itself over a few winters.

Bitumen is the carbon heavy part, so replacing some of it with waste plastic makes sense on paper. The catch is durability and microplastic release. A road that cracks early or sheds plastic is not a win. The Rutgers monitoring is the part that actually tells you if this works.
