General Information

Question Title

* 1. Thank you for your participation in this important survey. The purpose of this survey is to collect data regarding anaerobic digestion of municipal solid waste (e.g. food waste, yard waste, or fats, oils, and greases) at stand alone facilities, on-farm facilities, and water/wastewater treatment plants that practice co-digestion of sludge with other organic wastes.

EREF is a non-profit, non-partisan, non-advocating research foundation that supports sustainable waste management and the anaerobic digestion industry. The data collected in this survey will be presented anonymously and in aggregate form.

If you have any questions before or while taking the survey or if you would prefer to take the survey over the phone, please reach out to Margaret Cone at (918) 625-4120 or at

If your facility processes other waste streams using other technologies (e.g. composting, recycling, etc.), please provide information related ONLY to anaerobic digestion.

We look forward to hearing from you,

Bryan F. Staley, Ph.D., P.E., President & CEO
Suzanne Boxman, Ph.D., Data and Policy Program Manager
Margaret Cone, Research Assistant
