All receptacles containing recycling should be placed between the curb and sidewalk the night before pickup.
Please make sure to not include contamination in your recycling!
If any materials were left by the recycling truck, it very well may be because you did not follow a rule of accepted recycling (ex: did not break down large cardboard boxes).
The older, blue 20 Gallon recycling buckets are gradually being phased out. They are being replaced with two 65-gallon wheeled totes; one is to be used for paper/cardboard, the other is for plastic/aluminum. According to Somerset County, this process will take 2 to 3 years to complete.
