This is the good practice's implementation level. It can be national, regional or local.
About this good practice
Genesis BIO1 is the sustainable solution for saving conventional energy, streamlining production processes and reducing the amount of organic waste in the agri-food sector by producing renewable energy in cogeneration from biogas. Biogas plant uses energy crops, manure, crop residues, organic waste from meat processing, fat etc. from which it obtains biogas through anaerobic digestion. The biogas is filtered, cooled and sent to the cogeneration engine. Heat recovered is converted into steam and goes to CrisTim factory while electricity is injected into the national grid with 3 green certificates per MW / h. The digestate is used as a natural fertilizer.
Features:
- 1063 kW installed power
- Hours of operation: 8 400 hours / year
- Processed organic substrate: 60 t / day
- Electricity production: 25,5 MWh / day
- Heat output: 20 MWh / day - approx. 1 t / h (6,5 bar) + hot water 70 ° C
- Digestate (fertilizer) production: 18 000 t / year
- Efficiency: over 94%
2018 values::
- Biowaste transformed into energy: 22 970 t (11,94% biomass from agriculture, 88,06% organic waste collected)
- Electricity produced: 8 200 MWh delivered into the National Grid
- Thermal energy produced: 7 000 MWh
- Biogas production: 4 000 000 Nm3
The practice contributes to the circular economy of biological flows by producing renewable energy from biowaste and by using the digestate in organic farming. Main stakeholders and beneficiaries are CrisTim factory and farmers.

Resources needed
Genesis BIO1 is a project of Swedish-Romanian Genesis Biopartner holding that invested 4,5 million Euro in the biogas plant. AB Energy supplied the equipment, and MT Energie provided the fermentation technology and designed the automatization of the technology flux for producing biogas.
Evidence of success
Outputs (as of Nov. 2018)
• Over 5,5 years of operation in the field of renewable energy
• Over 46 000 hours of operation
• Over 94% efficiency
• Electricity produced: over 48 000 MWh
• Heat generated: over 35 500 MWh
• More than 50 000 tons of organic waste collected and exploited - environment protection

Potential for learning or transfer
This good practice could be applied with good results due to its many advantages:
- using various organic substrate: energy crops, vegetable residues, manure and organic waste
- the beneficiary of the resulting thermal energy can be any industrial consumer using hot water, technological steam and hot air - the plant can deliver an important amount of technological steam at a 25% lower cost.
- energy supply is predictable (over 8000 operating hours / year)
- it makes possible to store energy (biogas)
- such a plant creates 5 jobs and another 10-15 jobs in agriculture in the neighboring area
- electricity and heat recovery is subsidized by green certificates: 3 green certificates for each MW / h delivered into the national grid, which will help the investors to recover their investment in 8-10 years.
The model could be used by rural communities for valorisation of bio-waste and renewable energy production.
