Cloud and has taken on more responsibilities as a result.  Jonathan gr aduated from St. Cloud State University in the spring of 2020 with a BA in Mechanical Engineering\, and currently lives in St. Cloud\, Minnesota\, w here he grew up.\n\nDon Scheele has worked with Grede St. Cloud\, first as an environmental consultant\, and later as an environmental engineer for over 25 years.  In his current role\, Mr. Scheele is responsible for impl ementing the Environmental Management System for the plant\, which is an I SO 14001 certified facility.  Don graduated in 1981 with a degree in Civi l Engineering from UW – Milwaukee.  Don currently serves as Secretary/T reasurer for the AFS Twin Cities Chapter.  He lives in St. Cloud\, with h is wife and two dogs.  He enjoys fishing\, camping and canoeing in the Bo undary Waters Canoe Wilderness Area and the North Shore.\n\nAbout the Topi c:\n\nIn 2022\, Grede St. Cloud installed a bentonite recovery system to r eclaim bond material from a Disa sand system dust collector. The recovery system\, designed by KB Foundry Services\, adds water to the collector dus t in a mixer and separates the higher density sand from the lighter bond m aterials being recovered.  The bond materials are added to the muller for reuse.\n\nThe Disa sand system dust collector generates over 4\,000 tons of dust per year\, which was formerly sent to the landfill.  About half o f this dust is valuable bond material targeted for recovery.  The other h alf is fine sand grains\, which  are still sent to the landfill in as a w et sludge.  After a slow startup\, the system is now operating close to i ts design capacity\, processing about one ton per hour of collector dust.\ n\nAl Jacobson\, Jonathan Knafla and Don Scheele will present a discussion about the new recovery system.  Al will share his experience with instal lation and startup of the system\, Jonathan will discuss the system’s cu rrent performance\, and Don will present factors concerning waste aspects for the recovery system.\n\nSchedule...\n\n5:00pm      Social Hour - Cash Bar (on your own) &\; Hors d'oeuvres\n\n6:00pm      Dinner\n\ n6:45pm      Presentation\n\n7:30pm      Speaker Gifts &\; A nnouncements\n\nRegister below by Friday\, April 7th at 5:00pm.
