Buitink Technology finds it important to give extra inputs to
sustainability of the society and the environment on top of the
minimum requirements by law, already imposed by the government.
Besides certain obvious and easy to reach internal measures (as
for example separation of wastes, saving lighting, digital
treatment of documents etc.) we focuson the following main
- Reuse/ recycling of PVC coated polyester fabric
- Reuse/ recycling of ETFE foil
- Development of sustainable products
PVC coated polyester fabric
Often we (and other companies) use PVC coated polyester fabric
(pvc fabric) for various products.Think about covering canvas,
truck canvas, tents, tensed membranes etcetera.
Example of the different layers of a pvc coated polyester
PVC fabric is widely used for several reasons:
- Relatively low costs;
- Sustainability (many products that are realized from this
product are based on a lifetime superior to 10 years or even
- High availability;
- Numerous colors available;
- Various surface treatments possible (dirt repulsive, fire
- Easy to process and to print on.
Waste material is produced when pvc fabric is used as end
- the processing of pvc fabric, e.g. as cut losses.
- the end of the product's life cycle.
For both situations Buitink Technology proposes sustainable
solutions to deal with these waste materials: the texyloop
recycling process. Buitink technology proposes to recycle both
waste materials and redundant products with this process. For more
information read the following section.
The Texyloop process is based on the principle of separating the
PVC coated polyester fabrics into its basic materials
(polyesterfabric and pvc). In this process the pvc coating is
separated from the polyester fabric.
Residual pvc fabric from the production process as well as
redundant end product at the end of their life cycle (possibly
several years old) aretreated by Texyloop. The Texyloop process is
based on the Vinyloop PVC recycling proces (www.vinyloop.com).
The following picture presents the Textyloop process.
The Texyloop process (source: www.texyloop.com)
Buitink Technology has joined Texyloop and brings his cutting
wastes/ residual materials as well as the end products from pvc
fabric returned by the client at the end of their lifecycle.
Waste and products from pvc fabric are separated into the
- White pvc fabric (fire retardant)
- Colored pvc fabric (fire retardant)
- White and colored fabrics (not fire retardant)

Besides pvc fabric we also use ETFE foil. Usually the ETFE foil
is used in air-cushion roofs. These are permanent constructions
(there are ETFE air-cushion roofs that are more than 25 years
Also residual material and cutting wastes from ETFE (ethyl tetra
fluor ethyleen) foil processing, are granulated and returned to the
producer for recycling. As ETFE foil is a homogenuous product ( and
not a composit) there cycling process itself is much simpler than
the Texyloop process; the ETFE foil is granulated and again
extruded to make new ETFE foil.
Besides the recycling of ETFE foil we have plans to use ETFE
foil as raw material that is produced in an environmental friendly
This environment friendly production methods of ETFE granulate
soon will be presented by the producer Dyneon. They have introduced
a production process free of APFO (ammonium perfluoroctanat).
The first ETFE foil has already been produced with this
technique and we are testing the properties of the foil (e.g.on
load bearing capacity, feasibility of printing etc.).
The producer confirmed that the properties of the ETFE foil have
remained the same (sustainability, fire behaviour,
Development of sustainable and environment friendly
We are commited since a long time to the development of new
products and production processes. Various factors determine our
choice to develop a given product or to modify a production
process. A major criterium is the sustainability of the product and
its positive influence on the environment.
Criteria for a sustainable and/or environmental friendly
- The product collects waste materials and prevents these to be
diffused in the environment.
- The product is produced in a sustainable way, the impact on the
environment is significantly lower than in the conventional
- The use of this product gives a better protection of the
environment then existing alternatives.
In the past years we have developed following products complying
with above criteria
- Mobile water resistant floor (categorie A)
This innovation refers to a mobile liquid collection system made
of textile surrounded by inflatable tubes for e.g. the collection
and storage of dirty water from truck and car cleaning. This is a
relatively simple, cheap and mobile system that reduces the
threshold for recovering dirty water and prevents illegal
- Lightweight composite driving boards (categorie C)
This product is a light weight and sustainable alternative to
the existing (heavy) material (HDPE) and steel driving boards. The
use of these elements has several advantages such as a low
so-called ton-kilometers (thanks to the low weight and the small
thickness of the driving's plates transport is cheaper).

- ETFE air-cushion roofs (categorie B and C)
The ETFE air-cushion roofs are an alternative to (heavy) glass
roofs. For sure, when combined with a sun regulating system this
system has less impact on the environment than an alternative in

- Membrane and inflatable moulds (categorie B and C)
One development in which we invest time and energy is the
realization of moulds made of fabrics that replace the traditional
formwork or can be an alternative for pre-fabricated products.
Basically a lightweight mould can be build on location and be
covered with lightweight concrete. Not only construction time is
reduced but also more complex (BLOB) shapes can be made. This
process can be realized on site such that no pre-fabricated
elements have to be transported to the construction site (saving
ton-kilometers). Large size road transport of pre-fabricated
elements is expensive. Besides cement centers usually are to
be found near the construction sites (contrary to pre-fabrication

- (Insulated) membraneconstruction (categorie C)
The material used for tensed membrane constructions is very
light weight (about 1kg/m2) and can be completely recycled even
after many years of use.
There are even more recent developments using a double skin with
insulation in between. The final result is a building with very
good thermal insulation.
