New Materials for Biogas Production in Livestock Farms in Bulgaria
A comparative study was conducted for the production of biogas utilizing raw materials that are new for Bulgaria.The study included three types of beetroot: sugar beet,red beet and fodder beet in two variants.First variant: heads + leaves,Second variant: heads.For all the raw materials the following content was determined: dry matter,organic matter,nitrogen and crude ash (minerals content,including some toxic elements).The results of the analysis show that the highest values of dry matter were found i sugar beet in both variants: 20.61% and 28.12% respectively.In terms of organic matter content.the tendencies of higher values in sugar beet remain (13.51% and 26.21% respectively for both variants).Nitrogen content is highest in fodder beet-2.48% and l.90% respectively for both variants.and it is the lowest in sugar beet-1.65% and l.30% respectively for both variants.A tendency for higher crude ash content in fodder beet is observed ; the content of toxic elements such as cadmium and lead are highest in both variants.Sugar beet stands out with best values for each indicator characterizing the production of biogas.
