MOSCOW, July 16 Russian scientists from the Kazan State Agrarian University have developed a technology for creating biofuel from straw, it can be used as an alternative energy source, they told the press — university service.
«Researchers from the Kazan State Agrarian University and the Kazan National Research Technological University have achieved significant results in developing a cost-effective and environmentally friendly method for the production of biohydrogen — one of the most promising alternative energy sources. Scientists have proposed using straw — a widely available and inexpensive waste product — as a raw material for producing biohydrogen agricultural activities,» the press service said. 
Implementation This kind of fuel into industry will reduce dependence on fossil fuels, solve the problem of recycling agricultural waste, which will reduce the negative impact on the environment.
The university clarified that the main factor that allowed scientists to achieve the effectiveness of the technology is the optimization of the straw pre-treatment process. As Ilnur Gaifullin, senior lecturer at the Department of Machinery and Equipment in Agribusiness at Kazan State Agrarian University, explained, not only the potential of plant waste necessary for the production of biofuel, but also the level of negative impact on nature depends on the efficiency of processing.
“Today, there is no universal optimal technology for substrate pre-treatment. Its goal is to create such environmental conditions under which hydrogen-consuming strains are suppressed and producer strains are stimulated. However, some hydrogen-consuming ones can survive in substrates after pre-treatment, and some hydrogen producers, on the contrary, can be inhibited. This largely depends on the composition of the substrate nutrient medium, the presence of antinutrients in it and the metabolic processes occurring during fermentation,” Gaifullin added.
In the future, the researchers plan to scale up the technology and optimize pre-treatment processes to improve the economic efficiency of biohydrogen production from plant waste.
