Ecodesign, a new industrial economy?
Ecodesign
is a special
tool for turning sustainable development, based on a new equilibrium,
into
reality. It opens the way toward a new industrial economy — a
“socio-economy”.
Thanks
to the development of an architecture based on the idea of a “passive
building”,
the efficiency of heating has improved tremendously. Other
environmental issues
just as important, such as natural lighting or the management of water
and
garbage, have often been left in the background. In fact, part of the
gains
from improved heating has been offset by the growing consumption of
energy for
ventilation, air-conditioning and lighting. A new generation of
environmental
friendly buildings will have to take account of all forms of energy
consumption
— not just the energy used to occupy them but also the “shady” category
of the
energy for making and using construction materials.
Tools have
been
developed to assess the environmental impact of buildings by taking
into
account the making of construction materials, operations at the
building site,
the use of the building (heating and water consumption), its
demolition, and
the processing and recycling of its rubble. These tools for assisting
decision-making can serve to study technical innovations with regard to
environmental quality.
As the
results of the
recent “Grenelle of the Environment”, which assembled French officials
and
organizations for a wide-ranging discussion of ecological issues,
enter
into application, buildings should gradually switch from being the
foremost
consumers of energy to becoming producers of energy. The stakes,
technically,
economically and socially, are enormous. Packaging and the environment: An
assessment and the prospects The
environmental impact
of packaging still sparks strong reactions in public opinion.
Remarkable
progress has been made in recent years thanks to simple, logical
measures and
changes in regulations. The future of packaging is ecodesign. It takes
into
account a product’s environmental effects throughout its logistic cycle
and
life. This calls for more sophisticated analytical tools, which are now
being
developed.
The process
of
innovation in industry, particularly the chemical industry, is
undergoing a
change. It must be integrated into the ecodesign of products and
procedures.
From this viewpoint, the life-cycle analysis, a tool used to identify
effects
on the environment, falls short. A new tool, integrated in the process
of
innovation, is needed for steering ecodesign. Small business should be
able to
use it.
Energy and
materials: New points of view
Managing
the wastes produced by our way of living and the growing population
(especially
in cities) is a challenge for our societies. It must be taken up with
regard to
the objectives set by the recent “Grenelle of the Environment”, in
particular
the operational measures foreseen for reducing and recycling wastes.

More electricity for less CO2 Efficient
solutions
based on electricity exist for energy consumption by buildings,
industry and
transportation. Replacing the combustion of fossil fuels with them
should
significantly reduce CO2 emissions. On account of hydraulic
and
nuclear power, most of the electricity produced in France does not come
from
fossil fuels. This proportion should even increase in the future thanks
to both
the European pressurized reactor (EPR) and renewable energy sources,
including
wind power.
Ecodesign
often invokes
the concept of biodegradability. What does this mean? Several sorts of
natural
polymers are produced from renewable resources; but how to measure
their
biodegradability? What are the impediments to developing these
products? How to
overcome them?
Using
fossil fuels still
seems a necessity for the coming years. Given this, how to keep the CO2
thus emitted from spreading into the atmosphere? Capturing CO2
and
stocking it in the earth hold promise.
Is ecodesign
profitable for business? In
one opinion poll after another, consumers never stop declaring their
concern
about environmental issues. But do their purchases actually reflect
this concern?
Firms are proudly boasting about their “performance” on environmental
questions. But are they actually designing and backing “green”
products? What
role should public authorities play in this context?
A world
leader in
building materials, Lafarge is the only firm in this industry that, in
2008, is
listed among the 100 transnational corporations that are the most
committed to
sustainable development. For several years now, Lafarge has been trying
to
reconcile several concerns: industrial efficiency, the creation of
value,
respect for people and cultures, protection of the environment, the
conservation of natural resources and saving energy.
Agricultural
products
must satisfy both consumer needs (tastes and consumer confidence in
produce and
production processes) and citizen demands (a responsible, environmental
friendly industry and agriculture). AgriMip Innovation’s ambition is to
design
an engineering of innovation adapted to this situation thanks to an
original
analytical tool: “agro-chains”.
The concept
of ecodesign
was born in big corporations. Can it be transposed to small businesses?
The
development of environmental analysis software (product life cycle,
energy
balance, ecological footprints) has opened an access to environmental
data for
small firms. But might the latter not already be involved in ecodesign
without
knowing it? A study conducted in the Nord-Pas-de-Calais region suggests
this.
As feedback
from
experience shows, a step in finding the way to reduce a product’s
impact on the
environment is to become aware of it. This new way of looking at
products opens
possibilities for technical improvements and innovations. It is an
additional
driving force in creativity. It can increase a product’s environmental
added
value, make it stand out from rivals and even respond to new
expectations in
the marketplace. |
