See Hawaii DOE article on their refurbished playgrounds. DOE article
The Hawaii Department of Education has been refurbishing playgrounds at campuses across the state. As of February 2015, upgrades have been made to playgrounds at more than 20 schools, with 13 in progress and on track to be completed by June.
The refurbishment program’s approach is to reduce, reuse and recycle playground equipment, whenever possible.
The approach allows the Department to modernize playgrounds at lower cost, all while keeping the safety of children at the fore. After these considerations, the goal is to select the most exciting playgrounds to foster happy, healthy students with a ready-to-learn mindset.
A recent standard requirement of all refurbished playgrounds is the use of artificial turf to protect children from serious falling injuries.
