A GLOBAL PRODUCT RANGE
ECO2,
a concept which within THULICA AB gathers products with combined
good ECOlogical & ECOnomical values on short as well as long
terms. The growing concern of our environment requires
ecologically adequate products, which are also economical to use
in its technical application.
THULICA AB has built up an extensive experience in environmental
friendly products, such as natural antifouling products,
fertilisers, pesticides, industrial chemicals and hard fibres.
THULICA AB is a leading company in Europe when regards hard
natural fibres combined into a Soil Bioengineering concept.
The market is mainly northern Europe
including the Baltic States, supplied from Asia, Latin America
and Africa.
As large quantities of goods are carried on the water to Europe
and good network for storage, handling and inland transportation
is built up, good logistic control in distribution is obtained -
deliveries combined with our technical services are guaranteed.
As a consequence of THULICA AB´s position in the aspect of
ecologically adequate products, the manager is since 1986
appointed as advisor to the Swedish government and United
Nations (FAO) in the sector of natural hard fibres.
The growing international interest for natural fibres is clearly
shown by the fact that amongst other UN-organisations WTO
(ITC-UNCTAD/GATT) and SIDA (SWEDECORP), the Swedish aid
organisation, have initiated a number of projects supporting
production and marketing of products. Forthcoming event is a
FAO-proposed International Year of Natural Fibres (IYNF) 2009.

Soil Bioengineering
BIODEGRADABLE
GEOTEXTILES
Click for reference projects - in Swedish
Consequences for the environment at any
needed civil engineering project in our nature focus on
measurements to avoid negative impact on flora, fauna and
habitat in general.
Soil bioengineering offers solutions where a holistic view point
on the environment is paramount.
The core competence in Soil Bioengineering is the use of natural
components such as vegetation and thereto attached biological
processes to achieve a technical and biological holistic
approach to a technical or landscaping dilemma.
Soil Bioengineering projects are cost efficient, environmentally
friendly, aesthetically attractive and grow stronger over time.
Traditional civil engineering measurements may easily gain
attraction with soil bioengineering complements.
Soil bioengineering offers techno-economical projects for
habitat concern
slope stabilisation and erosion control
water course, river bank and shoreline management
wetland and run off water treatment
The effect will be a cost efficient technical project in balance
with nature.

EROSION - AN OLD
PROBLEM
The idea to use natural fibre for erosion control is not
new, but only until recently there has been no large scale
options. Now, the Gothenburg based company THULICA AB
launches GEOTEX-ECO2
geotextiles made from jute, and
coir into the Scandinavian market.
It's rather
obvious. As long as we have intervened in the nature we have
caused erosion. Using products from the nature to heal the
wounds is both efficient and thus economical. At second thought
it is remarkable that this product has not been available
before. In Europe man has during many years used living and
natural products, e.g. straw for soil preparation, however not
to any mentionable or industrial extent. Approximately 30 years
ago in USA it was discovered that the weave used for baling
cotton could be used for preventing erosion. The weave made from
thick jute yarn showed good water retention properties when
applicated on sensitive areas and prevented thus erosion and
assisted vegetation to root. Genius often emanates from the
simple - so also here - simply mats made from natural fibres.
Today industrially produced and fit for its purpose the
geotextiles are put on erosion sensitive areas as road banks,
park terraces or ski slopes after for instance sowing of grass.
|

Cuts and slopes are often
left without possible restoration. With geotextiles made
from natural fibres in the picture already at planning stage
the economy can improve as slopes can be made more steepy,
but primarily the appearance will be improved - and this
with products from the nature itself.
|

As we like to visit our beautiful sea shores man causes also
damages to the natural vegetation. By assistance of GEOTEX
fibermats one can again see the grass recovering its shore. |

GEOTEX
ECO2
- THE ENVIRONMENTAL FRIENDLY WAY TO PREVENT EROSION
A UN-study carried out by the German
environmental institute EPEA clearly shows that natural
fibre is the environmental friendly alternative to synthetic
fibre. Mainly because the natural fibre comes from renewable
resources and is a part of the ecological cycle. Amongst the
"green movement" - people today they talk a lot of long
lasting development and very much are pointing at a
renaissance for natural fibres.
Today natural geotextiles are made from jute from India and
Bangladesh and coir from India and Sri Lanka. Coir, a harder
fibre, biodegrades into the soil more slowly thus today
having more known applications compared to jute.
In the future also
sisal from Brazil and East African countries might be an
interesting alternative. Mainly the manufacturing takes place in
country of origin of the fibre, but approximately one third of
global production takes place in industrialised, mainly
European, countries for reasons of being close to the market and
consequent shorter delivery period and for necessary research
and development works.
Costs for using geotextiles made from natural fibres are
calculated to be lower than for alternative technics used today
already at construction stage as for instance the slope-angle
can be made more steep. On top also the maintenance will be less
extensive. Apart from supplying the geotextile THULICA AB will
also be your technical advisor and on demand also act as
contractor for the application.

The diagram illustrates a study
showing different geotextiles' water retention. It is determined
that natural fibre geotextiles will retain 1,5 kg/m2 whilst
synthetic mats only absorb 0,3 kg/m2. By difference in retention
it is clearly determined also the difference in erosion
controlling properties between natural and synthetic products.
(Source Dr. Prof. T S Ingold, England). |

Soon after application of the geotextiles the vegetation
sprouts. Assisted by the water retained in the geotextiles
the root system can calmly develop. After this stage, the
nature is given the assistance it needs to create a
permanent and lasting vegetation- the geotextile has
fulfilled its purpose and by moulding it becomes a part of
the ecological cycle without harmful wastes.
|

GEOTEX mats are available in
different lengths, widths and weight per square meter. Commonly
delivered as rolls, thus easily applicated. You only roll it
down the slope.

FROM ROAD PROJECTS TO
PRIVATE GARDENS
The geotextiles,
available in various sizes with different mesh, are binding the
soil and retain water - up to 5 times its weight. When the new
vegetation is well rooted and thus capacity to stabilise the
soil is obtained the geotextiles have fulfilled its purpose. As
they are fully biodegradable they simply return to the soil.
Coir from India moulders in Scandinavia - assisting the
ECO-system.
As permanent reinforcement, as in road banks, natural
geotextiles are not appropriate. Apart from that only your
imagination is limiting the areas of use. As example they can be
used on ramps, slopes and cuts at roadwork's, in parks, jogging
tracks, terraces at golf courses and dams.
They can also be used as protection for shores as temporary
reinforcement of prefabricated lawns and reinforcement of
temporary roads.
Options to improve landscaping are offered; sure is a green
slope more beautiful than a one created by stones. Earlier many
landscaping architects have hesitated to use synthetic
geotextiles in the soil when creating terraces or slopes. For
environmental reasons they don't want to use an oilbased product
that does not biodegrade. Now there are no hinders - use natural
fibre products. |

Erosion damages caused by wind, and water, but mainly by man is
a growing problem. By using natural geotextiles you can quickly,
economically and easily heal the wounds. |
