Introduction to Recipe Calculator –
Introduction to Outdoor Field Exercises – Building Compost Piles
Learning Objectives: Introduce the use of recipe calculator. Development of piles for monitoring of process performance for the school.
Topics to cover: Develop multiple feedstock recipes for the materials to be used.
Group Work: For developing of recipe, each group will be assigned to one instructor (with laptop) to work with a set of pre-defined materials. There will be 6-10 different materials available for use.
Break (move to the field and build test piles)
Pile Building Exercise: As soon as a group has developed their recipe, they will leave the class room and move outdoors to the pile building location. Two loaders will be available for building piles. Participants will mix the materials using pitch forks and scoop shovels. A water truck will be available for use to amend piles for moisture. Size of the piles will be limited to 5 cubic yards for appropriate use of materials. When the group is done, they can clean up and join the evening Dinner.
