Boston-Food waste-to-fertilizer producer Converted Organics Inc. is partnering with SafeLawns.org to put its organic products on display for visitors to see at the nation’s capital. Converted Organics reported that the demonstration project, on four acres of the National Mall, is in collaboration with the National Park Service and the Environmental Protection Agency to show off the advantages of organic products and practices over conventional methods. Safelawns.org, a non-profit organization dedicated to promoting natural lawn care, is conducting the test, which is divided into three plots to be evaluated by the NPS and EPA. All four acres were prepared by SafeLawns.org by adding compost, other natural soil amendments, and organic fertilizer before reseeding the area. Over the next two years, the NPS and EPA will evaluate each of three plots. One will be maintained conventionally by the NPS, a second will get standard organic treatment (maintenance via organic products), and a third will have a complete organic makeover with Converted Organics’ all-natural, organic soil amendment and fertilizer products. Rich Alea, vice president of marketing and development, explained that the company is participating because it is confident it will be a success. “With over 25 million people annually visiting our nation’s capital, we expect this will be a highly visible demonstration of the effectiveness of organics,” said Alea.
