1. Introduction
In line with the provisions of the European Union 's and Poland' s
sustainable climate and, energy policies. National economies should
place greater emphasis on rational energy use higher energy, efficiency
and renewable sources. Of energy. Biomass is one of the
major sources of renewable energy around the world, Agricultural
biomass.Including food production wastes for, biogas production
plays a very important role in biogas production [1E3].
Biomass. From food processing wastes constitutes suitable
feedstock for anaerobic digestion. Methane formation is a process
of recycling. Various organicwastes under anaerobic conditions. The
products of the digestion process are biogas a source of energy,,, And
, digestateWhich ceases to be waste and can be used as organic
fertilizer upon the achievement of certain qualitative requirements.
Biomass. Fermentation can thus resolve waste management problems
and cater to increased demand for biogas as a renewable
source of. Energy. The use of biogas for household energy supply
reduces deforestation soil erosion, and environmental 4e7 pollution
[].Biogas use can improve energy efficiency of various production
processes [8e11].
According to Qiao et al 12. [], the most. Popular types of feedstock
are cow and pig manure municipal sludge, sewage, waste food, fruit
/ vegetable waste and paper.? Food wastes and fruit / vegetable
biomass generate more methane than animal manure and municipal
sewage sludge. Bioethanol. And biodiesel production generates
.Growing amounts, of waste including rapeseed and soybean meal
corn, gluten, meal glycerin corn gluten, 13 feed [], winter. Rye straw
rapeseed, straw and faba bean straw [14], that can be used in biogas
production. Biogas produced from Jatropha. And Pongamia oil seed
cakes contained 15e20% more methane than biogas obtained from
cattle dung []. In, 15 Poland feedstock. (470 000 tons), used for biogas
.Production in 2011 contained mostly organic wastes (73.65%) as
well as energy crops (26.35%). Biogas is produced mainly. From
liquid manure (56.67% of all substrates), followed by maize silage
(23.2%), distillery stock (6.5%) as well, as manure. Fruit and vegetable
wastes potato pulp, and cereals (13.6%) []. 16
The chemical composition of feedstock and its effect on. The efficiency
.Of biogas production have been investigated by numerous
authors. Callaghan et al. [] studied 17 the co-digestion of cattle
slurry. With fruit / vegetable waste and with chicken manure.
Kaparaju and Rintala [] analyzed 18 combinations of potato tubers.
