Centralized manure AD-to-RNG systems can enable dairy farms of all sizes to collectively participate, including those who may not have the capital or land resources to build and operate their own AD system. One possible arrangement is to feed a single AD system with manure from multiple farms and upgrade biogas to RNG at the AD site. There are several factors to consider when planning for a centralized AD system for multiple farms; many are discussed in this fact sheet by Dairy Environmental Systems.en-USPRO-DAIRYDairyEnvironmentalSystemsmanurerenewablenaturalgasfact sheet
