Well when it comes to onions these days red and yellow onions can also be “green”. The concepts of sustainability and green energy are certainly not new but red and yellow onions are now on board. One of the nation’s largest onion processors in California (Gill Farms) has an onsite processing system that will convert the 40 percent of waste that is generated from their raw onion production to methane gas. This process will result in the reduction of thousands of tons of CO2e emissions each year and at the same time generate enough energy to save Gill Onions hundreds of thousands of dollars in energy costs. Who says “you can’t have your cake and eat it too”? From the restaurant supply chain management perspective it is a win/win whenever a supplier can both reduce costs of production and their “carbon foot print” at the same time.
