1. Vermicomposting: Promote Global Worming!

2. Darwin  Earthworms “The plow is one of the most ancient and most valuable of Man’s inventions; but long before he existed, the land … was regularly ploughed, and still continues to be ploughed, by earthworms. It may be (doubtful) whether there are many other animals which have played so important a part in the history of the world as these lowly, organized creatures. - Charles Darwin, 1881

3. Think about this: How can I change from “waste-ful” to being “waste-free”?

4. Common Species Lumbricus terrestis – Night crawler Allolobophora caliginosa – Grey worm Allolobophora chlorotica – Green worm Lumbricus rubellus – Red worm Eisenia fetida – Red Wiggler

5. Vermiculture & Vermicomposting Vermiculture is … “the culture of earthworms” Vermicomposting is … “using earthworms and microorganisms to convert organic waste into black, earthy-smelling, nutrient- rich humus.” - Mary Appelhof

6. Comparison of Composting Organic Matter Temperature –Compost bin = 130-160° F; 6-8 months –Worm bin = 59-70° F; year-round Air circulation –Compost bin = vents + turning –Worm bin = vents + worm churn

9. Worm Bins Size Construction –Plastic vs. Wood construction –Commercial Can-O-Worms™ Worm-A-Way® Worm-A-Roo™

10. Bin Construction Wooden Bin –Organic –Breathes –Heavy –Deteriorates faster –Can be built as furniture –No treated lumber or fragrant woods (ie: cedar) Plastic Bin –Lightweight –Holds moisture –Will not rot –Requires more holes for aeration –Inexpensive –Many bins available

11. 3 rd E : E nvironment A worm bin must be: –Convenient –Easily accessible –In a well-ventilated location –Covered and protected from wind, sun, and animals

12. Bedding Various materials: –Shredded newspaper –Sphagnum Peat Moss – Not Environmentally Friendly –Manure –Leaf litter –Coir (Coconut fiber) –Wood chips Dampen bedding with tap water

13. Bin Care & Maintenance Provide adequate bin and bedding mixture Maintain moisture level Provide air circulation in bin via adequate holes –Provides aeration –Controls odors by eliminating anaerobic conditions

14. Foodstock DO’s –Fruit & vegetable scraps –Banana peels –Grains & cereals, pasta –Tea bags & leaves –Cooked eggs & shells –Coffee grounds & filters –Onions & potatoes –Pancakes –Banana bread, cake –Leaves –Plant cuttings DON’Ts –Non-Biodegradables Plastic Glass Rubber –Pet feces (cats) –Toxic materials Ex: orange peels Plant cuttings treated with herbicides or insecticides

15. Other Organisms Mites & flies Predatory planarians Centipedes & millipedes Enchytraeids (white worms) Springtails Isopods (ie: sowbugs) Bacteria, mold, fungi, etc.

16. Harvesting Vermicompost Worm castings vs. Vermicompost –Worm castings are deposits that have moved through the worm’s digestive system; –Vermicompost is a combination of : Worm castings OM and bedding at various stages of decomposition Organisms such as worms and cocoons Microorganisms

17. Harvest Methods Dump & Hand Sort Method Lateral Method Vertical Method

18. There is no such thing as waste, just misplaced resources. How can YOU be more waste-free?
