Odour Emissions

Applies to: Biogas Plant

Description:

This indicator refers to the prevention of negative impacts of odour emissions on residents. The indicator considers distance of the plant to residential areas and abatement measures implemented. Common abatement measures include: feedstock and digestate stored in closed containers or covered with airtight and odour tight covers; AD process operates in a closed and sealed system; wind direction taken into account in the selection of plant’s location; use of biofilters, water mist dispersion systems, feedstock covering etc.

Questions:

What is the distance from the plant to the nearest residential area?

Which measures are implemented to abate odour emissions of the plant?

Rating:

Biogas plant located further than 500 m from the nearest residential area, feedstock stored in closed container or covered with tight covers, digestate stored in closed container or covered with tight covers, closed AD process

Biogas plant located further than 500 m from the nearest residential area, at least one measure applied

Biogas plant located less than 500 m from the nearest residential area, feedstock stored in closed container or covered with tight covers, digestate stored in closed container or covered with tight covers, closed AD process

Biogas plant located less than 500 m from the nearest residential area
