For Sugar mills

 The sugar mills are characterized by their seasonal arrangement of work (90-120 days a year). During the period of the plant operation, biogas plant can process beet pulp and molasses. Biogas plant can use conserved beet pulp or other wastes or to use energy crops and ensilage top of sugar beet for the complex not to stand idle after the end of the seasonal company.

  

 Fermentation of sugar production wastes follows two stage technology, because the pulp tends to rapid oxidation. Consequently, in order to increase the pH level in the hydrolysis reactor, fermented mass is sometimes loaded. The facilities designed for processing sugar production waste will be enough to recycle energy crops. The period of fermentation of energy crops is two times longer than that of pulp and molasses; however, due to a high energy potential, the daily load will be far less.

 

 Sugar mills consume large amounts of gas and electricity in the work season. They often possess their own boiler houses and electricity-generating plants. At the factory’s request, prepared biogas can be used for the production of electricity, or extraction of heating agent. Biogas refined with the special equipment is an analogue of natural gas, which can also be used for technological needs of the sugar mill.

 

 Typically, the sugar industry plants solve the waste problem through the production of dry fodder. Since such production is energetically unprofitable, the prime cost of feed is very high. Thus, this raw material is more useful to process into biogas and bio-fertilizer. Consequently, at the expense of its own waste, sugar mill covers its energy needs. Bio-fertilizers can be used on its own fields in order to improve soil quality and crop yield.
