This Biogas module provides reasonable expectations for investing in on-farm bio-digesters to convert animal waste to process heat and/or electricity. Learn how to calculate the number of animals needed to build a cost effective system.
Link to all of the Northeast Farm Energy IQ Curriculum, developed by Extension specialists from Penn State, Rutgers and University of Vermont.
This is part of the On Farm Energy Production Curriculum Series:
