Project 3.1: Dairy Waste to Energy Project
Project Manager - CH2M Hill

Project Overview

Goals and Objectives

The goals of Dairy Waste to Energy project are to:

• Develop technologies that can be used to maximize the energy recovery from animal waste
• Develop and evaluate different pilot projects that will include facilities at existing treatment plants and at individual and clusters of dairies
• Evaluate and test the effectiveness of low and high technologies developed in North America and Europe for the collection processing and energy recovery of animal waste

The objectives of the project are to:

• Assess and evaluate technologies available for the conversion of animal waste to energy including:
• Covered lagoons
• High-rate phased digestion (North American)
• European manure digestion technologies
• Thermal hydrolysis
• Pyrolysis
• Heat Drying
• Select Sites for animal waste to energy pilot plant(s)
• Design, construct and operate pilot plant(s)
• Summarize and evaluate economic and environmental costs and benefits associated with developing an animal waste to energy facilities.

Projected Outcomes

The Dairy Waste to Energy Project will generate the following specific work products: Process flow diagrams (which integrate the selected process advancements into the selected site) and preliminary facilities location plans depicting the conceptual layout of the pilot plant, the pilot plant test protocol Plan, performance specifications, site drawings, and one (or more) operating pilot plant(s) ranging in size from 60 kW to 5 MWs, with quarterly plant operating reports that document performance and needed modifications throughout the project.
