Problems

Technological transfer of experimental to industrial and commercial scale difficult: SBO new products, not known in the market. Need market and regulatory assessment. Entrapeneurial risk.

Solution based on virtuous biowaste cycle: SBO assisted anerobic fermentation process

SBO obtained from compost are added at 0,1 % in anaerobic fermentation slurry feed to yield digestate with reduce ammonia content, without affecting the biogas yield and quality.

LI FECAB objective: Demonstrate in real operational environment the following processes

Organic humid fraction (OHF) 

biogas + digestate  compost  SBO

OHF + SBO (0,05-2 %) 

4 % more biogas + no ammonia production

Key actions

• 1. Fabricate hydrolysis prototype (HP) with 50 t/ yr SBO production capacity
• 2. I nstall HP in the Acea MBW treatment plant (Pinerolo, I taly)
• 3. Validate the SBO assisted anaerobic fermentation process using one of the two OHF fermentation reactors of 2600 m3

capacity as control and the second for the SBO tratment

• 4. Replicate the SBO assisted fermentation process in Greece and Cyprus using local biowastes
