Waste in food and agriculture industry –
introduction
• There is in Poland waste monitoring system, however it does
not monitor data accurately for energy potential assessment.
•Thus evaluation has an expert character.
•The waste management area, especially incineration with energy
recovery is very public sensitive topic.
•The SRF area in the context of green energy production lays
between several polices subjects.

Waste in food and agriculture industry –
methodology
The assessment according to industrial branches
Utilization of officially available data (statistics, waste
databases)
Boundary condition:
-the stress on quantity assessment
-evaluation of existing utilization
Descriptive approach when data unavailable

Conclusions
There are necessary deeper (economical !) market studies
The factory level research advisable
Food industry manages its waste in the following sequence: turning
back into agriculture, composting, fermentation.
Some branches have been used bio-waste for energy purposes (grain
production, wood, paper sectors)
The biggest waste producers are the biggest energy consumers
Food production has often seasonal character and it must be
considered
