The process of anaerobic fermentation of organic waste makes it possible to produce not only methane, but also hydrogen, which, when mixed, form a high-energy mixture - biohythane. The efficiency of biohythane production in a two-stage anaerobic fermentation process depends on many factors, including organic loading rate (OLR) and hydraulic retention time (HRT). It is known that the addition of an immobilizing support materials to anaerobic bioreactors improves the stability of their operation and increases the bi...

There is a problem of ineffective usage of a significant part of the secondary resources formed as a result of industrial processing of agricultural raw materials that are usually wasted causing considerable damage to the environment. Sugar production from sugar beet is a major source of secondary raw materials. With an average yield of sugar of 10-12% to the weight of the processed beet, about 83% of beet pulp, 5% of molasses, and 12% of filter sludge are formed, which can be used to produce a variety of valuable...
