Regionalne możliwości produkcji biogazu rolniczego

100%

Jedrejek A. , Jarosz Z.

nr 6

Dokonano analizy dostępnej bazy surowcowej do produkcji biogazu rolniczego w ujęciu regionalnym. Substraty do produkcji biogazu to m.in. odchody zwierzęce (gnojowica) oraz kukurydza na kiszonkę. Najbardziej predysponowanymi do budowy mikrobiogazowni o mocy 50-100 kWe wykorzystującymi jako substrat wyłącznie kiszonkę kukurydzy są województwa: dolnośląskie, lubuskie, pomorskie, warmińsko- -mazurskie, wielkopolskie i zachodniopomorskie. W gminach skupionych w tych województwach istnieje także możliwość budowy mikrobiogazowni wykorzystujących do produkcji biogazu kosubstrat (70% kiszonka kukurydzy i 30% gnojowica).

The purpose of this paper was the analysis of the available raw material resources for the agricultural biogas production on a regional basis. The substrates used in biogas production are, among others, animal waste (slurry) and maize for silage. The most suitable voivodships for building a micro biogas plant of 50-100 kWe using maize silage as the only substrate are: dolnośląskie, lubuskie, pomorskie, warmińsko-mazurskie, wielkopolskie and zachodniopomorskie. In the local districts located in the aforementioned voivodships there is also a possibility of building micro biogas plants producing biogas from substrates such as: maize silage (70%) and slurry (30%).

The current study presents status and the need for improvement of the land distribution of family agricultural holdings in Poland. The assessment of the distribution of farm lands in the area between 1 and 300 ha has been made according to the 2013 data and provided by the Polish Agency for Restructuring and Modernisation of Agriculture (ARMA). Our analysis included totally app. 750,000 of family agricultural holdings. The evaluation of land consolidation was based on the two regional criteria proposed by the Regional Offices of Geodesy and Agricultural Areas, i.e. the plot size and the number of plots within individual family farms. The family agricultural holdings, that are included to the Polish system of agricultural support, have an average land area of around 16.0 ha, and this refers to around 6 cadastral plots with an average acreage of app. 3.0 ha. The need of land consolidation was estimated to be at the level of app. 7.1 million ha (this corresponds to 69.14% of total agricultural area land in Poland). The problem occurs in the entire country, but the worst situation is in the southern, south-eastern and central Poland. The implementation of the land consolidation and farmland exchange procedures within the Programme RDP (Rural Development Programme) in the period 2007-2013 stood at the level of 13,600 ha annually, thus the area of unfavourable land distribution was not reduced significantly. According to our evaluations the land consolidation should involve at least 50,000 ha annually to improve in real terms the distribution of agricultural plots in Poland.
