Helpful Hints.

  • Respect the rules. Unfortunately, recycling rules vary for different regions. Businesses, schools, and apartment complexes commonly use different recycling contractors that may have different rules. When you are out and about, don’t assume the rules  — ask and encourage managers to provide clear signage.
  • Stay informed. As markets shift, so does the recyling industry. Check these sources frequently to ensure you are aware of the current rules.
  • Missed recycling collection? Report residential recycling disruptions through Mercer County Improvement Authority’s web portal.

Help end wishful recycling.

Waste RecyclingRules 01

We all wish we could recycle more, but wishful recycling does more harm than good. Non-recyclables drive up the cost of sorting and plastic bags clog the machinery. If there is too much contamination, recyclers may discard the entire truckload.

Please ensure you are only adding acceptable materials to your curbside recycling bin, and help educate your neighbors.
