An announcement from Darien Recycling Center:

Some residents have noticed commercial vehicles backing into the transfer station and dumping loads of single stream recycling in with what they think is municipal solid waste.
Not to worry — a modification was made to the bays within the transfer station that allows commercial vehicles to unload recyclables here, making drop-offs quicker and easier than before.
Recyclables dropped here will soon be transferred to City Carting’s sorting facility in Stamford.
— This announcement was posted last fall on the Darien Recycling Center pages on Facebook. It looks like their announcement still timely enough to be posted on Darienite.com today.
