A unique trio creating renewable resources from organic residuals

DAR PRO Bioenergy works in close alliance with DAR PRO Solutions and DAR PRO Ingredients to create sustainable and efficient feed and fuel solutions for our world.  Our Solutions team collects used cooking oil and inedible fat & bone material from our restaurant and super market customers.  Our Ingredients team processes this material, along with inedible co-products from their meat processor customers, into feedstock that can be used in any of our three fuel production facilities... or into a variety of other sustainable applications, such as fat and protein ingredients that contribute to nutritional balance and digestibility in pet food, animal feed and aqua feed.  Also produced as co-products of our renewable diesel production process are renewable propane, renewable butane and NAPHTHA, more commonly known as mineral spirits.
