50k tpm

• Planned expansion capacity

Up to 100k tpm

• Total slag volume:

3.5m tons

• Over 5yrs

5.0m tons

• Over 10yrs

7.5m tons

Radiation safety

• All kinds of materials in the world have certain

amounts of radiation.

• There is no material with zero radiation!
• Members of the public are exposed to natural or

man-made radiation everyday.

• IAEA is the international organization for nuclear

safety with 168 member States (Qatar is a member State).

Materials (exemption limits) 1000 Bq/kg IAEA & Europe: 200 Bq/kg Germany: 185 Bq/kg Qatar: If radiation in a material < exemption limit:  Safe for humans  No monitoring control in usage

1 MBq: 1kg of low level radioactive waste 1kg of granite 1000 Bq: 1kg of coffee 10 TBq: 1kg of 50-year old vitrified nuclear waste 400 Bq: 1kg of Brazilian nuts 140 (avg.): Bq: 1kg of Qatar slag

Some examples (World Nuclear Association)

Average radiation dose from intake of food per person for a year. 400 μSv Radiation dose when flying from Doha to Paris

• nce a month for a year.

1,200 μSv

Some examples (dose)

29.2 μSv Spending 8 hours on a road made with Qatar slag everyday for a year (ACES field tests). << 1 flight

• Radiation blind testing conducted by 3

independent consultants/ labs from Germany, UK and France.

• A total number of 69 samples were collected by

certified Radiation Protection Expert and dispatched to respective countries.

• Each lab reported their results and conclusions.

Qatar Slag study

• Certified by government and IAEA:

 Germany: IAF – Radioökologie GmbH

 UK: Socotec UK limited  France: Radio-Protect 3rd party verification

• The Qatar Slag:

 Is exempted from any monitoring requirement  Can be used up to 100% in all layers of the roads  Should be treated as a normal aggregate in terms

• f transportation, storage & handling

 Is safe 3rd party conclusions

Quotes from accredited German consultant

“The slags tested by IAF are below the exemption and clearance levels under current German regulations that are much stricter than EU and IAEA exemption levels”. “Under European and German regulations all the materials can be used as construction material for

• utdoor roads and even 100% aggregate for concrete

for indoor use…”

German accredited lab: Radiation Free Declaration “Qatar Slag is ‘Radiation free’ as per European and German norms”.

UK Slag (used in road surface)

Qatar Slag license

MME is allowing up to 40% usage in limited applications.

• The Qatar Slag is undeniably safe
• 100% manufactured in Qatar
• Provides stable supply to the local market
• Consistent in quality
• Strategic to the Nation
