VOC Emissions Abatement Practices

Applies to: Silage Storage I; Silage Storage II

Description:

This indicator refers to the prevention of negative impacts of volatile organic compounds (VOC) emissions from the storage. VOCs are organic chemicals that have a high vapour pressure at ordinary room temperature and contribute to the formation of ground-level ozone, which is harmful to human health and vegetation. The indicator considers storage type (open or closed) and abatement measures implemented. Common abatement practices include tight packing of silage, after filling immediate closing of a storage with appropriate materials (plastic etc.) after filling, appropriate DM content of silage, appropriate handling of silage (clean and smooth storage face, minimization of loose silage on the storage floor, appropriate minimization of silage exposure to air), design of silo based on the silage needs (eg in regards to the required capacities), emission monitoring etc.

Questions:

Is the storage facility fully closed?

Which activities are implemented that abate emissions to air?

Rating:

Storage facility closed, at least four abatement measures implemented

Storage facility closed, less than four abatement measures implemented

Storage facility not closed
