Major Recycler Cheering Plastic Bag Bans, Including Chelsea’s Potential One

One of the largest recycling plants in the nation, Casella Waste in Charlestown, is hailing the recent spate of plastic bag bans in the area, including the discussions happening right now in Chelsea about a potential ban.

Casella handles about 200,000 tons of recycling per year and is the number one plant in Greater Boston – and a top five plant in the U.S. They handle all of the recycling for Chelsea, but one thing they hope is that the City might follow Boston in banning plastic bags – known in the industry as Low Density Poly-Ethylene (LDPEs).

“By far, plastic bag getting into the facility are the number one contaminants in single-stream recycling,” said Bob Cappadona of Casella. “By themselves, they are a very recyclable product. However, there just isn’t any market for the product. Second, with everything else, they get caught up in our machinery and cause us a lot of problems. If they come into our facility and get past our pre-sorters, they tend to get wrapped up in our disk screens and they wrap around them and cause stoppages.”

He said when bags get caught up in the disk screen machinery – which separates plastic jugs from paper/fibre products – the only way to remove them is the old fashioned way:  with a razor blade.

“There are so many that get in there that at lunch or at break time we have to keep two or three people there to clean the disk screens of plastic bags,” he said. “Every three or four hours we have to go in and clean it up.”

Cappadona said he doesn’t want to malign plastic bags because they are a good recycled product on their own, if people were to take them back to the grocery store as directed.

However, many people throw them in the recycling, many times because they don’t know. On its face, it looks like something that could be recycled in the traditional curbside barrels. However, it is one plastic item that isn’t accepted, but routinely gets in the stream.

In Chelsea, Russell Disposal picks up all the recycling on the curb, and from there, they take it to Casella on Rutherford Avenue, behind Bunker Hill Community College in Charlestown.

Once there, that’s when problems come.

“They are a good recycling product on their own, but when they get here with everything else, they are a contaminant,” he said.

In terms of the ban that will go into effect in Boston, Cappadona said they aren’t really preparing, but they are excited about it. And they hope others might follow suit to make their recycling product purer.

The Chelsea City Council has been exploring the idea of a ban for the last month, with two meetings so far on the issue. While many are calling for a ban to prevent litter and for environmental reasons, businesses in the area are concerned about the increasing cost burden it will put on them to use alternative bags that are more expensive.
