About us

We are a company dedicated to the milling and granulation of cereal straw from Castilla: wheat and barley, and to the packaging of first quality chopped and pressed straw. This constitutes a fundamental contribution of fiber in the production of compound feed for animal feed.

We provide these essential components by supplying ourselves with the straw that abounds in the cereal fields of Castilla.

Milling and Granulation SL


The origin of the company dates back to 1986, when its founder: Carlos Martínez García, who had been dehydrating alfalfa since 1962, perceived the need for existing straw fiber in the animal feed market, and decided to take advantage of the surplus of cereal straw that was traditionally burned in the Castilian countryside.

Since then it has become one of the main manufacturers of straw by-products. With facilities of 15,000 m2 in the main industrial estate of Burgos: Villalonquéjar Industrial Estate, its production has been growing until reaching 40,000 tons per year, which are distributed in the national territory (80%) and abroad (20%).
