The third International Industrial Rocks &
Construction Material Forum ,
31rd March – 1st April 2015.
Open new horizons for the recycling the
wastes of IR & Construction Material

We are 7 Billions inhabitants today. We will be 9 billions in 2050 :
Traditional human behaviour is not affordable anymore
The “Take-Make-Reject” historical way of life:

jeopardizes non renewable resources

assaults our environment
Make
Take
Reject
Environment
Historical oily ponds and contaminated
soil
The consequences, as
an example
Natural ecosystems : a
sustainable model
Minimum consumption of resources (material, water
and energy), based on optimum recovery of rejects
Industrial Ecology : Inspired by the
efficiency of natural ecosystems
A scientific approach which consists of mimicking
the low consumption equilibrium of ecosystems
Lower
consumption of
natural resources
Minimum of
rejects
 Someone’s waste becomes resources for others
 Energetic Surplus = Energy sources
 Logistic improvement (supply + collection)…
Waste Equivalent Energy
•
1 kg waste
10 MJ
•
1 kg fuel
42 MJ
•
1 kg carbon
30 MJ
•
1 kg dry wood
15 MJ
•
1 kg dry peat
12 MJ
10 MJ of energy can heat 80 litters of
water by 30°C = 1 hot shower !
10 MJ can light a bulb for 9 hours

The cement process is by
nature a top-flight treatment
solution
 Full destruction of organic waste compounds
- high temperature, long residence time
 High efficiency gas cleaning inherent to process
 No residue (ash) since minerals get combined
Traditional incineration :
2 sec. - > 1200 °C, as the most
stringent requirement for high
chlorine content wastes
up to 25 % of slag to get rid of
15 m
up to 5 % of hazardous fly ashes

Lafarge vision
• Being sustainable
The production of one ton of
cement necessitates non-renewable
raw materials and generates CO2
emissions.
Replacing a part of fossil fuels with
alternative fuels offers a response
to this double environmental
challenge and provides an
economically viable waste
treatment option to local
communities.
Ambitions 2020
50% of non fossil fuels (30%
biomass)
