Solid waste is picked up twice weekly by the Township, and there is an active recycling program.
A dropoff recycling center is located on Main Street in Millburn. Since its incorporation as a municipality by the State of New Jersey in 1857, the Township of Millburn has operated under the Township Committee form or government. Although the official governmental form has not been changed in the municipality's 134-year long history, a significant change took place in 1985 in the responsibilities of the five Township residents who are elected to membership on the Township Committee. Until 1985, each Committee Member was assigned responsibility for the activities of a specific branch of municipal government, such as police, fire or financial operations, etc. Today those administrative functions rest in the hands of the Township's Business Admin-istrator, the highest official on the Township's professional staff.
