Rebounding from the crisis
It is this innovative mindset that Mr Wurth
hopes Luxembourg’s manufacturing sector will
embrace. Finance is now dominant, but as presi-
dent of the Chamber of Commerce he supports
the drive towards sustained economic diversity.
He is convinced that Luxembourg has to become
“the benchmark in terms of productivity” whilst
also continuing to seek out “high-quality speci-
alities and niche products with a very high added

Key to this is the fostering of innovation, a con-
cept he feels needs to be addressed from all sides.
“I’m not just thinking about new products,” he
comments, “but also about innovation in terms
of customer service and customer-supported
R&D activities.” Thanks to the fresh thinking of
Arbed, Arcelor and today ArcelorMittal, he says,
new technologies have continued to sell well

                                          thriving eco-technologies sector. This area of activity may, as yet, be less visible
                                          than other sectors of the Grand Duchy’s economy, but it is growing fast. Actively
supported by the government, the sector already features a wide variety of new companies specialising in areas ranging
from solar panels to biogas plants and energy conservation – to name but three examples presented in this section. Other,
more established players are also involved, such as steel industry supplier Paul Wurth with its increasingly eco-eff icient
technologies. The country’s public research centres are at hand to support the sector with vital R&D input.

   Empowering eco-technologies
   Concern for the environment is triggering a sharp rise in the demand for eco-friendlier products and processes. Cleaner
   technologies are urgently needed to conserve energy and resources, curb pollution and avoid waste. Imagination, dedica-
   tion and know-how will be required to meet this challenge, together with a blend of research excellence and entrepre-
   neurial spirit which Luxembourg is fostering assiduously. The Grand Duchy is actively supporting the eco-technologies
   sector – as a way of contributing to greater sustainability, but also as a means of diversifying its economy.

The plan goes beyond reinforcing Luxembourg’s
eco-technologies sector, seeking to accelerate
the use and acceptance of environmental
technologies by “encouraging already established

economy to move into these new markets,”
Ms Polfer remarks. It also seeks to “promote
the adoption of environmental technologies
and encourage innovation and research in this
area”. The ministry has, for example, announced
f inancial support for companies using
external expertise to help them improve their
environmental performance.

Creating momentum
One of the plan’s key elements is to bring the ac-
tors together in a “cluster” of businesses and re-
search organisations in the eco-technology and

Marc Solvi’s raw assessment of the necessary
strategy for his company. Given the nature of
the global market he feels that the group has
no choice but to develop high-end products and
services, as it cannot hope to compete with the
lower-cost producers. “It is essential to keep

         Turning nature into power
         It might not be immediately obvious, but new energy sources
         can be found everywhere in nature. For almost 10 years now, the
         Luxembourg engineering f irm L.e.e. has been building agricultural
         and industrial biogas plants to convert biomass into biogas, pro-
         ducing power and heat. This is an environmentally friendly and
         carbon-neutral technology, and farmers, towns and enterprises
         are already benef iting from it.

         L.e.e. was established in 2000 in the town of
         Junglinster, to the north of the capital. The f irm’s
         name, an acronym based on the Luxembourgish
         for farming, energy and environment, clearly
         reflects its philosophy: farms generate plenty
         of biomass, organic material from plants or ani-
         mals, which can easily be converted into energy.
         A sound business proposition, as the f irm’s
         annual turnover growth of about 15% would
         tend to prove.

         The company currently employs 13 people,
         mainly engineers, and is actually a spin-off
         of the EU project LSDN (Local Sustainable
         Development Network). LSDN enabled cities in

                         tonnes of organic household waste per year. Our

                         which is enough to supply 15,000 households.”

For a lower carbon footprint ... globally
Reducing carbon footprints is the goal of many, if not all, companies in the eco-technologies sector. Rotarex, a market leader
in industrial valves, is helping to push this drive forward for automotive applications. In its Luxembourg headquarters, the
company has already developed a comprehensive range of products enabling engines to run on compressed natural gas or
liquef ied petroleum gas, thereby reducing carbon emissions by up to 30%. Rotarex is also working on hydrogen technol-
ogy both for internal combustion engines and fuel cells – leading-edge innovation paving the way for tomorrow’s zero-
emissions vehicles.
