Rubber Mulch Replacement

There were several facets to the decision to replace the rubber mulch in MPS playgrounds with engineered wood fiber. First, let’s go over what playground cover materials are. Rubber mulch is made by grinding up recycled tires. The size of the tire chip is usually quit small (less than ½ inch) and provides a flexible surface that is impact resistant. The downside of the rubber mulch is usually odors (the tires can emit odors when first placed) and the black surface can be very hot during the warm summer days. Engineered wood fiber is ground more finely than ordinary landscape mulch, is from virgin wood, and has had the saw-dust removed. It provides a safe and natural way to cover the ground while still providing an adequate amount of cushion and protection for children. The downside can be the wood degradation over time and wood fiber needs adequate underdrains to keep the wood dry. Other playground surfacing includes artificial turf and solid rubber surfaces. Both are very expensive and have high maintenance cost. Some playgrounds also use sand and pea gravel, however, those playground surfaces are not ADA accessible.

After careful consideration,the MPS Board of Education made the decision to remove all rubber mulch from MPS playgrounds and replace it with another surface material that meets requirements for accessibility and function (including fall protection and access for all students). MPS relies on a U.S. Consumer Product Safety Commission handbook to guide decision-making on playground cover. MPS has two available playground-cover options, wood and rubber mulch, because its playground equipment is over four feet high. So selection of engineered wood fiber was made to replace the rubber mulch in playgrounds at MPS. The wood fiber projects also include underdrain features to help with keeping the wood materials dry.

The school locations listed below will participate in the rubber mulch replacement project.
