A special feature of our biogas plants is that they are standardized. This reduces the design therefore capital expenditures significantly. In order to do primary calculations of a silage-based biogas plant, you should know:

  • silage moisture content;
  • quantity.

Silage moisture content is 70%.

If it is difficult to determine the silage yield from one unit area of agricultural lands, you can use some statistical data:

In order to obtain the maximum silage output, fields are sown with maize hybrids. Statistical data for the yields of different varieties of maize hybrids widespread in the agricultural sector are given below.

*If non-hybrid maize varieties are cultivated, it is necessary to take into account the yield of 35 tons of silage from one hectare.

Example. 70 tons of silage of non-hybrid maize varieties, or 110-140 tons of silage of hybrid maize varieties can be taken.

180 m3 of biogas with methane content 55-60% can be produced from 1 ton of silage.
