TECHNOLOGY

The Aerobic Thermophilic Digestion technology (ATD) developed by UOR achieves a standardised 72 hour bio-conversion of food waste in a more efficient way than other processing methods.

ATD modules of various sizes are available that can be installed as stand alone units or added to existing waste systems to reap the benefits of faster processing, smaller tonnage footprint and an end-product that is a valuable fertiliser constituent.

The ATD advantage

Backed by a proven, patented process.
Reduced throughput time – a 300% gain on most existing alternate processes.
Small footprint – ATD equipment will usually locate within an existing plant area adding processing volume. Stand-alone’ ATD plants will process up to tenfold the volume of other systems.
Produces a ‘value added’ end product, diverting away from costly soil amelioration or disposal.
The liquid stream may be further refined to a ‘fit for purpose’, pasteurised low COD/BOC recycled water (e.g. for wash-down/irrigation, etc.) saving on intake water charges.

Installation Options:

1. STAND ALONE PROCESS MODULES

The modular design of the ATD system

allows for low volume startup units to be upgraded with bolt-on capacity as demand rises. ATD modules range from 5 tonne/day to 200 tonne/day.

2. ENHANCE ANAEROBIC DIGESTION (AD)

ATD is the perfect addition for Anaerobic Digestion (AD) facilities as it can solve two problems:

The requirement to pasteurise the material, this is often a ‘bottle neck’ in the AD process and the low value, wet, sticky, soil nutrient robbing nature of AD end product.
Adding ATD, as the end process to an anaerobic digester, achieves pasteurisation and full ATD bio-conversion in 46 hours for an end product with quality values.

3. INCREASE EXISTING COMPOST THROUGHPUT

ATD's 3 day cycle can be a tool to expand production within the existing footprint of composting plants with 50 to 90 day process cycles.

4. IMPROVE EXISTING EFFLUENT PLANTS

ATD can be engaged as an add on to existing food processing effluent systems to stabilise their performance, taking up ‘surge’ or ‘over capacity’ volumes for rapid 48 hour processing.
