in conjunction with partners, pursue opportunities for the processing of high volume waste where:

regulatory environment is currently, or is becoming, favourable

conventional disposal methods do not represent a viable long term solution

continuous supply of 30,000 – 200,000+ tonnes per year of a specific waste stream

in conjunction with partners, build/own/operate waste processing centres (or license technology in special circumstances):

minergy has design and construction expertis

minergy has an operational team with more than 10 years experience in managing and operating minergy facilities

Market Opportunity Minergy Experience

Fly ash/bottom ash

Large scale international opportunities to process municipal solid waste incinerator (MSWI) fly/bottom ash & coal fly ash (potential for more than 50 plants worldwide)

Successfully operated fly ash - aggregate waste plant for 7 years; experience in processing incinerator fly ash /bottom ash; Minergy technology endorsed by multiple large MSWI processors in Europe

Auto Shredder Residuals (ASR)

In 2015, 95% of all end-of-life vehicles must be recycled in Europe; Minergy technology can process ASR mineral fraction

Minergy technology endorsed by the Netherlands Government mandated organization responsible for all ASR processing

Hazardous waste Significant opportunity worldwide

The US EPA endorsed Minergy, successfully concluding a multi-year study processing PCB's from river bed sediment

Mining and mining refining waste

Opportunity for 20+ Minergy plants world wide

Minergy has unique patent pending technology to process Spent Pot Lining (SPL) waste

on the following slides are high level reviews of 3 opportunity case studies, which collectively represent a potential for 50 minergy plants in the next 10 – 15 years:

European municipal solid waste incineration (mswi) bottom ash and asr

European mswi fly ash and air pollution control (apc) residue

spent pot linings (spl) from alumina processing

in 2006/2007, minergy successfully processed:

Bottom ash from one of the largest European mswi operators

complex mineral fraction from the leading asr reprocessing company in Europe

not further progressed at that time due to lack of scale at each facility

re-engaged clients in 2010/11 and updated conceptual designs

secured interest from multiple new parties in 2011

have received letter of intent (loi) from asr reprocessing company

minergy’s technology has been endorsed by a number of leading mswi companies in Europe

active discussions underway with mwsi companies representing more than 35% of the total Europe market

minErgy status

more than 60m tonnes of municipal solid waste (msw) is incinerated in Europe each year, producing about 15m tonnes of bottom ash

currently certain fractions of bottom ash can be re-pro-cessed.

traditional means of processing remaining bottom ash fractions – through stabilisation and back filling of mines – are not a sustainable as regulations are changing

minergy technology represents an economical and envi-ronmentally sensitive long term solution

mswi Bottom ash and asr

investment opportunity is greater than €1B (us$1.4B)

aggregate annual revenue opportunity is more than €600m (us$800m)

substantial additional bottom ash opportuni-ties in other geographies

minergy has successfully processed fly ash from one of the largest mswi companies in Europe at its test facility in the usa

a unique aspect of the minergy proprietary design is the ability to process waste streams with a high salt content (5–50%+) as this is critical when processing some apc residues

minergy’s technology has been endorsed by a number of leading mswi companies in Europe who have need for an alternative means of processing fly ash/apc residue

active discussions underway with mwsi companies representing more than 20% of the total Europe market

minErgy status

approximately 3m tonnes of mswi fly ash/apc residue produced each year in Europe

additional large volume of fly ash produced by a wide range of other industries

fly ash treatment process has a number of similarities to treatment process for bottom ash

minergy represents a superior long term solution to other approaches

mswi fly ash/apc rEsiduE in EuropE

typical plants will treat 100,000 – 200,000 tonnes per year

market opportunity is for 5 – 10 plants

plant investment should be similar to comparably sized fly ash plants:

€30m – 40m

us$40m – 55m

yearly revenue per plant:

€20m

us$30m

total market opportunity:

€250m (us$350m) of capital investment

in 2011 minergy developed a patent pending system for the treatment of spl

the minergy design is highly innovative and combines a number of proven tech-nologies (including minergy’s glass furnace technology) into a single integrated plant

multiple by-products are produced by the treatment process, which can be resold commercially – some at a significantly value

the minergy design has been reviewed in detail by one of the largest environ-mental services companies in the world

minErgy status

aluminum production is a continuous process where different materials are molted within a refractory lined ‘pot’

spl is produced as a waste stream from this process

approximately 500,000 tonnes of spl produced each year, and volumes are steadily increasing

spl is expensive to treat, with no sustainable solution to-date

much spl is being stockpiled around the world in hope that a viable long term solution will be developed in the future

substantial r&d has been invested over the years to develop a long term solu-tion by numerous governmental and industry parties, without success

spEnt pot lining

regulatory conditions globally continue to evolve to support de-ployment of minergy technology for the treatment of spl.

currently about 50% of world-wide spl producers (i.e. 250,000 tonne) can justify a minergy solution

typical plants will treat 25,000 – 75,000+ tonnes of spl per year

plant investment:

€35m – 50m us$50m – 70m

yearly revenue per plant will typically be:

€20m us$30m

total market opportunity is

€200m (us$275m) of capital investment €150m (us$200m) of revenue per year
