Biodiversity and natural areas 7 action lines for Solvay
1. Rehabilitating large quarries and settling ponds
• Multi-annual, large-scale rehabilitation
programs of natural areas are on-going
in many Solvay sites. In particular, the
biological rehabilitation of old dikes and
quarries on Solvay’s lands has been
under way since decades.
• Around 2000 hectares have been
actively replanted, often with trees.
Some of the rehabilitated areas are even
now recognized as nature reserves to be
protected.
• In addition, Solvay owns and maintains
over 8000 hectares of land around its
sites, where biodiversity is de facto
protected from housing or roads and
plays its role as a natural buffer.
Example of Couillet, Belgium
2000 ha replanted on Solvay lands,
1bis. Rehabilitating natural areas
example in Dombasle (Jura)
2000 ha replanted on Solvay lands,
• Partie importante des surfaces du site de l’usine gérée en «zones vertes », en zones humides et en plans d’eau, soit au total 300 ha.
• 200.000 arbres et arbustes replantés
2. Promoting biodiversity in our sites
Young falcons in Jemeppe, Belgium
Many action on a case

sites
ex :
•Neder Over Hembeek
•Nature reserve in
Santa Luce (Italy)
•…
3. Taking part in protection of natural environment around our sites
Example : "Clean Up Day" (septembre 2012) du
Galgenschor, une réserve naturelle le long l'Escaut
(en face de Solvic Lillo).
Journée organisée par Natuurpunt. Solvic Lillo a
collaboré à nettoyer cette réserve naturelle (déchets
venant des bâteaux sur l'Escaut).

4. Ensuring sustainable biosourced raw materials
(*) based on projected final energy demand in 2020
Expected world Biomass Trade Routes (*)
• wood pulp
• bio-ethanol
• C12-C14 alcohols
• guar split
• lauryl alcohol
• hydrogenated coconut oil
• glycerin
• coconut fatty acid
• + Several industrial projects thoroughly
investigated in wood-based energy
sourcing.

Solvay’s manufacturing units based on its proprietary
Epicerol process probably constitute one of the
world’s largest “green chemistry” projects (excluding
the biofuel industry), in terms of volumes of bio-
based chemicals produced. The Epicerol process
meets the 12 principles of green chemistry as defined
by the US Environmental Protection Agency:
• From the extraction of raw materials to the output of our
factories, the process reduces by 55% the consumption
of non-renewable energy and by 60% (of which 35% of
biogenic CO2) the overall impact on climate change,
compared to the conventional method based on
propylene.
• In its own industrial perimeter, the Epicerol process
reduces by a factor 8 the volume of chlorinated by-
products, of 10 the water consumption and of 2 the
chlorine consumption. It also significantly reduces the
volume of liquid effluents.
The Epicerol® process is one of the world
largest “green chemistry” industrial projects.
It relies on natural glycerin, a by-product of
biodiesel from rapeseed, oil palm or
soybean
Solvay strives to work with suppliers who share its
sustainability commitment.
• Rapeseed - of European origin, it is covered by the European
Directive on renewable energy which commits suppliers to
various criteria of sustainability, including biodiversity.
• Oil palm - of Southeast Asia origin, suppliers are members of
the Round Table for Sustainable Palm Oil (RSPO). Part of
the supply by RSPO’s members is certified according to
RSPO’s criteria on protection of biodiversity, soil, water,...
and working conditions (no child labour).
• Soybean oil - of Latin America origin: the supplier is
committed to environmental specifications excluding
deforestation, child labour, or the irresponsible use of
pesticides.
5. « Indices biotiques » pour mesurer l’impact sur la biodiversité aquatique
Objectifs
suivre l’amélioration continue de la qualité de nos rejets aqueux (après traitement physique et/ou biologique) par des mesures in situ dans le milieu naturel
Principe la qualité écologique du milieu récepteur aquatique (rivière, baie) s’évalue par la richesse de sa flore et de sa faune (biodiversité) – « decision tree »

6. Protecting ecosystems by saving the water resource 35 sites identified as in
potential water scarcity
situations
Action plans to reduce water
withdrawals focus in priority
on groundwater abstraction
and on the 35 sites
identified as in potential
water scarcity situations,
current or future, due to
climate change.
• Currrent freshwhater water
withdraxwals by Solvay
amount to 600 Millions m3.
The impact on water
availability is lower as a
large part of water is used
for cooling purposes and
then returned to the same
environmental compartment
(surface to surface).
Example : Solvay now recycles
water and has reduced
consumption from phreatic by 4
million m3/year in its Rosignano
plant in Tuscany, protecting the
phreatic and the natural
ecosystems
Example : Technical and
financial support to
international scientific
missions:
Studying the biodiversity of
the tropical primary forest :
the “SolVin - Bretzel” in
Madagascar (2001),
Panama (2003),
the "Arbodôme" in Vanuatu
Islands (2006)
