Waste challenges
Main advantages:
Excellent for treating the biodegradable organics of the waste.
Moisture in the input is a blessing.
A natural way, with very low emissions, if at all.
Available Mechanical Biological Treatments
Dry separation + Aerobic composting (Composting).
Dry separation + Anaerobic Digestion (AD).
Main problems:
The non-biodegradable materials must be fully pre-sorted.
If not – The output of the biological treatment is contaminated and unusable.

Biological Treatment
MAIN UNSOLVED PROBLEM: HOW TO SEPARATE AND TREAT THE BIODEGRADABLE ORGANICS ?
ArrowBio:
Hydro Mechanical Separation
+
Multi stage Anaerobic Digestion
--------------------------------------------------
= Clean organic stream + Green Energy + Recyclable Materials

THE OPTIMAL SOLUTION ArrowBio
Fact : Biodegradable organics behave different than other materials, while in water
Technological Brief Separation Process
• Unique Hydro mechanical Separation
• Clean Organic to AD process
• Use of materials for recycling
Anaerobic treatment
• A two stage fast anaerobic process
• Mesophilic process .
• 97% of water are recycled.
• Production of Biogas and Electricity

Send only 20%-30% of the waste to Landfill (mainly inert residues)
Substantially increase recycling percentages (70%+)
90%-95% of materials are separated
Minimize pollution of Landfills and Incinerators
Competitive waste treatment costs
Produce renewable electricity & high quality digestate
Become Environmental leaders
Create new green jobs

Customer’s motivations
Biogas content ~ 60% - 70% Methane
100 m3 biogas / ton organic MSW @ 60% Methane
Heating value ~ 0.24 MWhr / ton of organic MSW
Electricity Generation ~ 90 kWhr / ton of organic MSW
CNG ~ 5.5 m3 biogas = 1 GGE – Gallon of Gasoline Equivalent
