Micro biogas plants – The prospect of

development in lodzkie province

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.

Lodzkie province

Area:18 219 km2

24 districts, 161 communities

QuestionnaireThe 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).
