RESEARCH PRODUCT

A Closed Biotechnological System for the Manufacture of Nonfood Products from Cereals

subject

description

The production of nonfood products from agricultural raw materials is an important challenge. Efficiency of grain processing for sustainable development depends to a large extent on the harmony of the proposed system. Such a system must include consideration of all steps in the cycle from preparation of the field through cultivation of the grain crop; harvesting; total biomass utilization during processing stages; treatment of wastes; and back to preparation of the field. A closed biotechnological system can be recommended for processing of agricultural raw materials. Ethanol production from potatoes in a closed system is presented in Figure 1. Lysine production is represented schematically in Figure 2, while details are given in Table 1. A semiclosed biotechnological system of leaf protein production from green biomass, integrated with straw and farm waste utilization, was realized in the Bauska region farm “Uzvara” in Latvia. This system includes lactic acid fermentation of juice and presscakes and methane fermentation of brown juice, together with pig manure and straw.
