4. Emerging Technologies
New technologies being introduced constantly.
Implementation slow to materialize in US.
Most new technologies involve thermal
conversion, electricity generation, or fuel production.
US market success heavily reliant on commercial
viability.
Oxalor is a unique waste conversion technology based
on relatively simple concepts that generates
marketable products from household waste.

5. Criteria for Success of Emerging
Waste Management Technologies
A working technology is only the 1st step.
Reference facility in commercial operation, using
similar feedstock, in this case as-delivered municipal
solid waste (MSW).
Vendor willing and able to accept financial and
performance risk.
Marketable products to support diversion claims.
Competitive tipping fee
Focused expertise leveraging and complementing your resources
6. Study Background
Oxalor is a patented waste conversion technology, with
US patents pending.
Viridia, Int’l owns exclusive licensing rights to the Oxalor
technology in the US.
Value Added Consulting was engaged by Viridia
International to conduct an independent feasibility study
of the Oxalor technology.
Feasibility study was used to facilitate company and
project financing.

7. Oxalor Background
The process was developed in France more than 10 years ago.
Original development was for use in converting wastewater
biosolids to fertilizer.
Testing was conducted on different feedstocks including MSW.
After successful testing, the developer was able to execute an
agreement between the Oxalor Group and a coalition of 18
regional municipalities to build and operate an Oxalor MSW
facility for 20 years.
The facility ownership is divided between the municipalities (51%)
and the Oxalor Group (49%).

8. Oxalor MSW Development
The facility sponsors applied for a permit to construct and
operate an Oxalor facility using MSW.
Extensive regulatory scrutiny in permitting facility in
France, including comprehensive Environmental Impact
Statement.
Representative sampling and analysis was conducted
directly by local regional governmental entity.
Analysis was completed for metals and contaminants, as
well as agricultural components.
Permit to construct and operate and MSW Oxalor process
was granted in 2010.

11. After the ThermoAbsorber
After Thermo-Absorber, material is completely
dry, pathogen-free, and reduced in size.
Trommel separates bulk of organic fraction, which then goes
through refinement (removal of small Fe, non-Fe, inerts).
Trommel overs go through fully automated MRF using
optical sorting, magnetic and eddy current separation and
inert removal.
Non-recyclable but combustible materials shredded and
marketed.
Residue is completely inert.

34. Extensive Economic Scenario
Analysis
At a tipping fee of $45/ton, analyzed economic viability
using:
Three material recovery rates
Three different recovered material revenue assumptions
(low, medium and high)
Extreme low tipping fees tested.
$0 revenue for Oxyom tested
Economic viability is probable in every scenario tested.

35. Findings
The Oxalor process successfully converts MSW to a usable
soil amendment, and recovers materials for recycling.
The technology is fairly simple.
Capital costs are significantly lower than other conversion
technologies.
Both landfills and transfer stations can benefit from Oxalor
through extension of useful life, or diversion of waste for
disposal.
Would make significant progress towards 75% goal

36. What’s Next
Discussions with FDEP indicate permitting is
straightforward.
Project discussions being held with municipalities and
private vendors in Florida, NJ, Ohio and other
locations.
Collaboration with universities and agricultural
extensions to explore product applications and facilitate
independent peer review.
