Multistar XL star screen helps boost compost production The Miramar Greenery crew and their new Multistar XL
City of San Diego adds its third Komptech machine The City of San Diego’s Miramar Greenery is one of the top producers of quality compost in Southern California. The City purchased its first machine in 2002, when they had a big need to remove plastic contamination as well as silverware in waste collected from the Miramar Air Base food waste program. Three years later the city purchased a Komptech Magnum trommel screen to replace their old trommel, which had started to develop maintenance issues. The Magnum trommel feeds directly into the Komptech Hurricane windsifter and produces very high quality finished compost. With the growing demand and increased size of their operation, Miramar needed another screen to process material, so in 2009 the City purchased a Multistar XL star screen to keep up with their production needs. This new screen allows the Greenery to produce over 300 yards of material per hour, while removing plastic contamination and metal. In addition, the star screen gives instant product adjustability, so the Greenery can

produce their many products without having to change out drums or screen segments. One of the biggest advantages with the new Multistar XL is its ability to run completely on grid power. With the 480/60 US current electric drive already installed, if work needs to
be done to the engine, or simply to take advantage of the lower cost of operating with grid power, all the Greenery needs to do is plug in. As its needs grow, San Diego plans to continue to look to Komptech to help in their composting equipment needs.
The Multistar’s throughput, economy and quality output are helping Miramar boost production
A properly managed compost pile essentially sterilizes manure. Pathogens are destroyed by heat and by other, more benign bacteria, which are in turn consumed by higher-order organisms as the pile cycles through the composting stages. 9
