Regulatory News:
GCC, which is always looking for innovative and sustainable
solutions, is extending its collaboration with Hoffmann Green
Cement (Paris:ALHGR). With the recent arrival of Néolithe, GCC has
taken a further step forward in the deployment of low-carbon
concrete. The three partners have just poured an invert for a very
low carbon footprint fuel loading slab for RTM (Régie des
Transports Métropolitains) in Marseille. The H-UKR concrete used
incorporates 20% aggregate produced by accelerated fossilization of
non-recyclable building site waste manufactured by Néolithe. This
invert will be used by GCC's engineering and technical department
to take precise measurements in terms of decarbonation and
durability compared with the use of traditional concrete.
Asked to create a temporary bus depot site in Marseille for RTM,
GCC Provence's Travaux teams and GCC's Technical Department seized
the opportunity to launch a series of tests on the strength,
durability and behavior over time of Hoffmann Green Cement
Technologies' first H-UKR concrete made with Neolithe recycled
aggregates. The target element for the test is the fuel loading bay
slab of the depot.
For the first time, GCC has also partnered with Néolithe, the
creator of a new material, Anthropocite. This patented process
consists of mineral aggregates derived from the accelerated
fossilization of mixed non-recyclable waste materials such as
plastic, wood and glass wool. For this GCC project, 20% of these
aggregates are incorporated into Hoffmann Green Cement
Technologie's low-carbon concrete.
While the use of this concrete changes nothing in terms of
processing, it does change everything in terms of carbon footprint:
the H-UKR + 20% Anthropocite formulation produces 62 kg CO2eq/m3 ,
compared to 167 kg for traditional CEM II/A concrete.
In practice, GCC poured two identical slabs for comparative
purposes:
- A slab with traditionally formulated
concrete - A slab with 370 kg/m3 of Hoffmann 0% clinker cement,
combined with aggregates derived from the fossilization of Neolith
waste (20%), in addition to the 80% of standard aggregates.
Tests have already started and will continue during the two
years the loading slab will be in operation. Deformability
measurements are scheduled at 1, 2, 3, 5 months and one year. Then,
after 2 years of operation, load-to-failure tests will be carried
out for both formulations (tradi, low-carbon), in order to later
compare the difference in long-term mechanical behavior.
“This project perfectly illustrates one of GCC's key priorities,
which is to work on the implementation of sober and sustainable
solutions. The work we've been doing for several years with
Hoffmann Green Cement Technologies enables us to take tangible
action in this direction, and the partnership with Néolithe enables
us to take a further step in the direction of decarbonization, an
essential issue for the building and construction industry”, says
Patrick Dubourg, Executive Vice-President of GCC.
“Since 2020, our collaboration with GCC has continued to
strengthen, and this project is a clear demonstration of that!
Together, with visionary partners like Néolithe and RTM, we are
determined to revolutionize construction by decarbonizing it.
Thanks to Néolithe's innovative recycled aggregates, our ambition
is clear: to supply the world's most carbon-free concrete today,”
says Julien Blanchard, President and Co-founder of Hoffmann
Green.
Laurence HEMERIT, Director of Infrastructures: “RTM, which is
very committed to reducing the carbon impact of its activities, is
interested in any initiative in this area. We found GCC's proposal
very interesting in that it enabled us to carry out a large-scale,
long-term comparative test to assess the qualities of low-carbon
concrete. Our temporary bus storage site was therefore the ideal
candidate for this experiment.”

About Hoffmann Green Cement
Technologies Founded in 2014 and based in Bournezeau in
the Vendée region, Hoffmann Green Cement Technologies designs,
produces and markets innovative cements that are highly
decarbonized, with a carbon footprint divided by 6 compared to
traditional cements, and which, at equivalent dosage and without
any modification to the concrete manufacturing process, offer
superior performance compared to traditional cement. With a 4.0
production site and soon two more, the group has industrialized a
real technological breakthrough based on modifying cement
composition and creating a clean, clinker-free cold manufacturing
process, making it a leading and unique player in the cement
market, which has not changed for 200 years. In a context of
climate emergency, Hoffmann Green Cement is therefore playing an
active part in the energy transition by working towards
eco-responsible construction and promoting the circular economy and
the preservation of natural resources. Thanks to its unrivalled and
constantly evolving technological know-how, supported by
high-performance teams, Hoffmann Green Cement Technologies
addresses all markets in the construction sector, both in France
and internationally. https://www.ciments-hoffmann.com/
About Neolithe Founded in
2019 by Nicolas Cruaud, Clément Bénassy and William Cruaud,
Néolithe currently has 200 employees. Their shared mission is to
efficiently process non-recyclable waste using Accelerated
Fossilization. This innovation, which captures more carbon than it
emits, revolutionizes waste management by transforming it into
stone, enabling all waste to be recycled into useful aggregates for
the construction industry.
About RTM
Régie des Transports Métropolitains (RTM) operates the urban and
interurban transport networks and complementary mobility services
