Elkton Dairy Farm Joins Green Energy Effort
Zwemmer Dairy in Elkton is joining a growing number of farms in an effort to help the environment.
It has leased a plot of land to South Jersey Industries so the company can build a methane digester at the farm's Z-Star location in Caseville.
The digester takes cow manure from the farm and processes its methane output into usable energy, contained as a liquid in heavily-pressurized tanks.
