The county board of commissioners, on Nov. 19, approved plans to build a 200-foot-diameter base recycled glass piling facility. Crushed glass is used for county road projects.

The location of the new glass piling facility will be west of Fergus Falls, near the solid waste transfer station. Nearby is the Fergus Falls Municipal Airport.

There are six transfer stations in different areas of Otter Tail County, operated by the county’s solid waste department.

Also approved were associated access roads and drainage features. Permitting through Fergus Falls Township will be required prior to the start of construction.

Otter Tail County has contracted with Interstate Engineering for survey and engineering site design services. A bid package will be necessary for the purchase and installation of recycled glass piling equipment and materials.

The new facility will be capable of storing 800 cubic yards of glass.

Many Minnesota counties, including Otter Tail County, are using reclaimed glass as aggregate.

Aggregate is a broad category of coarse to medium-grained particulate material used as a base for roads. Examples, in addition to crushed glass, include sand, gravel, crushed stone, slag and recycled concrete.

The use of a 10 percent blend of crushed glass for road base has been proven to be not only effective but also safe.
