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.

THE OPTIMAL SOLUTION ArrowBio

Fact : Biodegradable organics behave different than other materials, while in water

Process Logic

Hydro Mechanical Separation & Preparation

Multi Stage Anaerobic Digestion

SBR

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

ArrowBio Soil Experiments

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
