Chesterfield, Missouri -- A US study of the life-cycle profile of soya products, study funded by the United Soybean Board (USB), confirms why manufacturers increasingly turn to US soya in green chemistry for a wide variety of products that are sustainable, says a 17 March announcement from the Chesterfield, Missouri-based board.
The current study updates a US Department of Energy's life-cycle inventory (LCI) with data from 2001-2007. As part of the study, a life-cycle impact analysis of four soy-derived feedstocks methyl soyate, soya lube base stock, soya polyol and soya resin using the updated LCI data was carried out.
The updated data showed each soy-based feedstock reduced greenhouse gas emissions and cut the use of petroleum, compared with similar petrochemical-based products.
In other USB news, the group says it has supplied some funding for a project in which Niemann & Associates will soon begin applying the first-ever biobased-certified soya-based adhesive for built-up roofs (BUR) on commercial buildings.
"Low-sloped commercial roofs are predominantly BUR, which are typically constructed using hot asphalt that contains carcinogens and produces toxic fumes during application," said the USB statement. According to the company, the cold-applied soy-based adhesive contains 28 percent biocontent, in accordance with ASTM standards, and contains soya bean oil and glycerin, a co-product of the biodiesel manufacturing process.
The soya-based adhesive contains less than half the asphalt of traditional BUR adhesives and could replace more than 500 million gallons of asphalt over a three-year period.
