HELECTOR’s “Dry” Fermentation Technology

Placing the substrates into the empty dry fermenter (e.g. wheel loaders, strewing carriages) 

Warming by the start of the aerobic degradation process (aeration from the ground)

Conditioning for the following fermentation

Ventilation stop and start of the percolation

As soon as the required biogas quality in the dry fermenter is achieved the exhaust air pipe is shut 

and the biogas pipe is opened.

The biogas production in the dry fermenter reaches the maximum and then decreases slowly. The 

methane content increases constantly and reaches values of up to 80 %

Stop of the percolation, dripping and drainage of the substrates

Aeration of the dry fermenters, interruption of the anaerobic process 

“Garage” type fermenter

Electricity export

“Dry” vs. “Wet” Fermentation

Significantly lower water requirement No mashing requiredEffluent free operation possible

Lower process energy requirementno mixing mechanism requiredMinimal electric and thermal energy requirement

Less movable machine partsless material wear

Modularly extendable plants

Synergie in the use of agricultural equipment (e.g. wheel loaders, tractors, mixing carriages, manure spreaders etc.)

Simpler (stackable) storage and treatment of digestate

No heating of the dry fermenters

Current status of Biogas Projects in Greece

• Despite  the  high  potential  in  Greece,  currently    the  greatest percentage  of  the  installed  capacity  of  plants  utilize  biogas  from landfill  sites and sewage treatment facilities (39.9 MW)

Athens Ano Liosia Landfill, 23.5 MWel

Thessaloniki Tagarades Landfill, 5.05 MWel

Athens Waste Water Treatment Plant, 

Psytaleia Island, 11.4 MW

Ano Liosia landfill, Athens (Helector 50 % Shareholder)

One of the largest power production plants from landfill biogas in the world, with installed capacity of 23,5 MWe. In operation since 2001Thermal energy retrieved is used for the landfill leachates treatment plant

Current status of Biogas Projects in Greece

• One of the largest power plants from biogas globally of installed capacity 23.5 MWe. operation since 2001.

• 11 x Deutz TBG 620 v16 • 4 x Jenbacher JMS 620 B.L• Produced power sold to the DESMIE S.A. (

Power Administrator of Greece).• Thermal recovery of energy used for biological

treatment of leachate from Fyli Landfill • Granted rights for 10 MW expansion in Fyli

Current status of Biogas Projects in Greece

• 5,0 MWe in Tagarades, Thessaloniki. In operation since 2007

• 4 x Deutz TBG 620 v16

• Produced power sold to the DESMIE S.A. ( Power Administrator of Greece).

• Expansion perspective by 2,5MW

Constraints in Biogas Projects Development in Greece 

Feedstock supply chain issues•Ensuring continuous supply over plant’s lifetime•Great dispersion of primary sources•Need of a well structured logistics mechanism•Dependence on “others” activities (Farmers, Industries, etc.)

Obstacles in Environmental licensing 

Insufficient Projects’ financing  •Lack of experience in business risks from biogas projects operation•Banks are reluctant for financing due to the current economic situation in Greece

Lack of synergies. Investments in Biogas Plants would be more attractive in case of plant integration with other activities:‐District Heating of local residences or industries‐Green houses heating 

Thoughtless Renewable Energy Plants installation  requests from anyone ‐Application’s accumulation in authorities‐Commitment of power grid lines ‐Delays in “serious” investments

Financing Issues –Problems  Identification & solutions

No  risk  assessment  &  management  in  main  issues  such  as  supply  chain,  licensing obstacles,  technology  use.  Business  plans  should  be  very  analytical  and  accurate  on these issues

Greek  Banks  do  not  have  the  required  experience  in  relevant  projects  – And  in  the current situation nor the necessary liquidity.

Great delays in the absorption of subsidies resources 

Sense of  insecurity    for  “feed  in  tariffs” levels    in  long  term  basis  – Extra  taxation  in renewable projects as in 2012. Need of clear warrantees in pricing policies by the state.
