2. Aim
 to obtain the optimal scheme of agricultural biogas
plants based on technological, legal, and economic
location criteria in the context of waste management
of agro- and food industry, dairy plant waste and
other agricultural waste.

3. Lodzkie province
Area:
18 219 km2
24 districts,
161 communities

4. Questionnaire
The study was conducted in the Lodz region in the group of 51 respondents
The main objective of the study focused on three aspects:
 Determination of the potential of lodzkie province for
generation of waste for biogas production in biogas plant;
 Determination of the place where there is the largest
concentration of plants, which can deliver organic waste for
biogas plants;
 Determining the potential of building of biogas plant for its
own needs by plants generating the highest number of
organic waste
The survey technique was used CATI (ComputerAssisted Telephone Interview).
