ABSTRACT
The increasing production of biodiesel in Brazil also increases glycerin production, a co-product of this industry. The main component of glycerin, glycerol, is highly energetic and because of that, glycerin is already used as animal feed in many countries. The objective of this paper was to evaluate the chemical composition of glycerin produced by biodiesel plants in Brazil and discuss its potential utilization as animal feed. Forty one samples of glycerin from sixteen biodiesel plants, that together yield 85.1% of Brazilian biodiesel, were analyzed. Chromium, cadmium and lead were not detected in any studied sample. Only four plants, that together yield 36.8% of Brazilian glycerin, comply the glycerol and moisture content levels established by the Ministry of Agriculture, Livestock and Food Supply. Only one, responsible for 14.1% of Brazilian glycerin, delivers glycerin with the potential to be used as ruminant feed once it doesn't use animal fat to produce biodiesel.
