Caramuru to produce ethanol from soya beans


Brazilian company Caramuru (Sorriso, state of Mato Grosso) is to produce hydrous ethanol from soybeans and will also process soy lecithin. Its deputy CEO, Cesar Sousa said the unit’s capacity is 6.8 million liters and 3,000 tons of lecithin.

Other than the use of fuel, hydrous ethanol can be used for perfumes, cleaning materials, solvents, and paints. Some experts believe that the new technique could be used by other processors around the country.

Caramuru had a revenue of R$ 4.02 billion ($1.2 billion considering the current currency exchange) in 2016.

The company has 2,768 employees and exported nearly $552.4 million last year. In order to ship its products, Caramuru often uses multimodal ways such as the railway, the waterways of Tietê-Paraná and Tapajós-Amazonas, and also has investments in the ports of Santos, São Paulo, and Santana, state of Amapá.

Ethanol production soybean molasses

Soybean molasses is composed mainly of soybean sugars and it is obtained as residue the process of soybean protein concentration. Sugars composing the molasses are more complexes than those found in sugar cane or in corn, becoming the fermentative process a challenge.

Yields obtained overcame expectations. Today we have a process production of soybean hydrated ethanol on industrial scale having a production cost 50% lesser with regard to the process with sugar cane.

Use of soybean hulls for production of purified protein and second generation etanol

The purpose of the project is to study the viability of ethanol production the soybean hulls through production techniques of second generation ethanol described in the scientific literature, obtaining a concentrate of soybean hulls as a coproduct.

The project has the objective of aggregating value to the lesser commercial value product soybean crushing industries which corresponds to roughly 5% of the entire soybean mass processed. Production techniques of second generation ethanol involve high cost operation, not being viable economically. Concentrated soybean production concomitantly with that one of ethanol makes economically feasible the two products.
