Construction and Wood Debris Recycling

During the 2005-2006 fiscal year, Stony Brook University recycled over 14,000 tons of asphalt, brick, and concrete material from campus construction projects and converted that material into a reusable product referred to as "stone pack".

The machine you see in the pictures below pulverizes the construction related debris into an aggregate which is then mixed with dirt. This end product has excellent compaction qualities and is utilized in the construction of new campus roadways and the maintenance of existing roadways.

Along with the natural resource conservation benefits this process helped save the University approximately $200,000 in avoided disposal costs and product supply.

Road Debris

During that same period, Stony Brook University converted 1,600 tons of woody debris material (leaves, pallets, stumps, and brush) into a high quality mulch product.

Using the machine pictured here the process involves double grinding this material into mulch which is then left to stand for approximately six months while it cures and ceases all micro-biotic activity.

The University is entering the eighth year of managing woody debris in this manner. In addition to the conservation of forest resources, this process creates a high quality mulch product that is used throughout campus in various landscaping and aesthetic improvement applications to help conserve water and suppress weed growth.
