The Darling family began their rendering operations in the mid-1800’s in the Chicago Stockyards to address the needs of the meat packing industry. In those days, the animal by-products were used in fertilizers, tallow, wax and many other useful household items. Today, those same by-products are used in jet fuel, tires and other commercial products!
Darling offers national services as well as services in Mexico. They have one of the best equipped and staffed analytical lab in the rendering business and exports approximately 30% of the products they produce such as tallow, meat and bone meal and yellow grease which is sold to enhance the fat in poultry and hog feeds. In addition, that grease will be used in bio-fuels and green diesel.
