Silage Effluent Storage Capacity

Applies to: Silage Storage I; Silage Storage II

Description:

This indicator refers to the prevention of negative impacts of silage effluent on the environment. Silage effluent has a Biochemical Oxygen Demand (BOD) of up to 200 times that of raw sewage and it is highly acidic. The indicator considers silage effluent management (separately stored or not) and the permeability, capacity and location of the storage. Recommended capacity of the silage effluent storage is at least 20 litre per m3 of silage storage (capacity of the silage storage less than 1500 m3) or at least 27 litre per m3 of silage storage (capacity of the silage storage larger than 1500 m3).

Questions:

Is silage effluent separately collected?

Is the silage effluent storage impermeable?

What is the capacity of the silage effluent dedicated storage in comparison to the capacity of the silage storage?

Is the storage facility located in a sensitive groundwater area?

Total storage capacity?

Rating:

Silage effluent separately stored, the storage impermeable, with adequate capacity and located outside groundwater sensitive area

Silage effluent separately stored, the storage impermeable, with adequate capacity and located in groundwater sensitive area

Silage effluent separately stored, the storage impermeable, without adequate capacity and located outside groundwater sensitive area

Silage effluent separately stored, the storage impermeable, without adequate capacity and located in groundwater sensitive area

Silage effluent not separately stored

Effluent storage is permeable
