Presentation Title: “Value-Added Products for Composting Operations”

Session: “Compost Uses and Markets: Expanding Opportunities”

Time: Wednesday, January 30, 11:00 AM – 12:30 PM

Presentation Summary: You can increase the bottom line of your composting operation by adding vermicomposting and tea production to your activities. If you sell compost for ~$30 per cubic yard, you can increase its value tenfold (or more!) by feeding it to worms. Worm castings (called vermicast or vermicompost) sell for a minimum of $200 per cubic yard. Many people are selling it for $700 per cubic yard. With the right packaging, you can sell vermicompost for 2-1/2 times that price.

I interviewed 18 worm farming operations for my new book, The Worm Farmer’s Handbook: Mid-to Large-Scale Vermicomposting for Farms, Businesses, Municipalities, Schools, and Institutions.Many of the facilities pre-compost feedstocks and feed the compost to earthworms. The facilities that are making the most money manufacture/sell compost, vermicompost, soil mixes, and teas.


Workshop Title: WORKSHOP 6 (HALF DAY): Boost Profits for Your Composting Operation with Value-Added Products

Time: Monday, January 28, 8:30 AM – 12:00 PM

Workshop Summary: In addition to manufacturing and selling compost, you can produce vermicompost and teas/liquid extracts that will sell for much higher prices. Is your compost selling for $35 per cubic yard? How about feeding it to worms and selling the product (vermicompost) for $700 per cubic yard? With the right packaging, you can sell vermicompost for 2-1/2 times that price. Zachary Brooks will describe his composting/vermicomposting/tea production operation and Rhonda Sherman will share profiles and tips from her new book The Worm Farmer’s Handbook: Mid- to Large-Scale Vermicomposting for Farms, Businesses, Municipalities, Schools, and Institutions.
