Current status


Emerging TechnologiesNew 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.


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


Study BackgroundOxalor 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.


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%).


Oxalor MSW DevelopmentThe 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.


Value Added Consulting Feasibility Methodology

Conducted independent review and analysis of previous research conducted by developer.

Site visit to reference facilities in Lezay, France to observe operations.

Grab samples of product and analytical testing at US laboratory.

Analysis of project economics using several material recovery and recycling revenue scenarios.

After the ThermoAbsorberAfter 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.

Extensive Economic Scenario Analysis

At a tipping fee of $45/ton, analyzed economic viability using:Three material recovery ratesThree 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.


FindingsThe 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


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.
