AERATED STATIC PILE SYSTEMS
AERATED STATIC PILE (ASP)
Aerated Static Piles (ASP) are a simple and efficient way to compost challenging feedstocks like food waste, biosolids and manures. ASP’s are simple because they don’t require turning and require less than half the area of turned windrows. Smaller footprints result in reduced land costs, smaller leachate ponds and reduced paved surfaces. While ASP is simple in principle, it is not easy to design in practice. Some poorly designed ASP systems have insufficient blower capacity or air distribution leading to temperatures that kill beneficial microorganisms which slows the process and causes odors. GMT has never had an ASP facility close because of odor complaints.
RADIAL AERATED STATIC PILE (RASP)
One of the biggest challenges with aerated static pile systems is making a well-constructed pile and topping it with a biocover. GMT’s Radial ASP (rASP) system is designed to build the perfect pile by using a computer controlled telescoping conveyor to automatically build the pile without the use of a front end loader. The conveyor builds a homogeneous pile with lots of porosity which is ideal for effective aeration. The conveyor can also reach back over the pile and place the biocover for vector and odor control. Automated telescoping conveyors are also more efficient and cost 75% less per hour to operate. The Radial system takes ASP composting from “one touch” to “NO TOUCH” processing.
