Introduction
 In recent years, environmental problems and
recycling issues are being discussed
 Recovering waste material from used beverage
cartons (UBC) to manufacture a value-added
product with an economical and efficient
method is an important issue from the
perspective of environmental pollution
 UBC can be recycled using a thermal
compression process to manufacture home and
building products
Polyethylene: seals in liquid food contents
Polyethylene: adhesion layer
Aluminum: barrier to oxygen, light
Polyethylene: adhesion layer
Paperboard: for stiffness
Polyethylene: barrier to moisture, bacteria

Introduction
 Aseptic beverage cartons can be used to repulping for paper
applications
 Aseptic beverage cartons can be used to process converts
shredded cartons into thermally compressed to make a high
strength bio-composite panel alternative to traditional wood
based panels such as:
• Particleboard
• Medium density fiberboard (MDF)
• Oriented strandboard (OSB)
Developed by
Tetra Pak®
®
Yekpan
 UBC is produced in Turkey
 Yekpan® is composed of
70–90% paper
 10–25% low density polyethylene
(LDPE)
 UBC cartons collected from consumers are
shredded and then molded together under
high temperature and pressure as
illustrated in Fig. 2
 The process uses the whole waste package
without leaving any waste.

UBC cartons are shredded into 5 mm particles
In this process,
Particles formed in a layer

 Advantage of UBC carton raw material
• Panels made from recycled cardboard does not only
have any formaldehyde but also have very low resin
amount reducing overall production cost
• Panels have certain content polyethylene which does
not contain any formaldehyde
• Panels manufactured from recycled materials would
be considered as an alternative solution to forest
resources problem
The objective
 The objective of this work was to evaluate some
properties of the cardboard substrate with wood
veneer sheets as an alternative product to wood based
panel substrates such as :
• Particle board
• Medium density fiber board
• Oriented strand board
 Determining of water resistance and mechanical
properties of cardboard panels overlaid with wood
veneer sheets using various adhesives
The objective
 Determining of glueline strength (delamination test)
between veneer sheet and cardboard substrate
 Determining of the adhesive type having the best
glueline strength among experimental adhesives was
also aimed
Materials and methods

Discussion
Physical properties
 Cardboard panels polyurethane plays an important role to have
a good contact between the particles. Polyurethane melts during the
press of the panel creating a very strong bonding between particles
which enhance thickness swelling of the products. Moreover small
aluminum content in the particles is also acting moisture barrier
and contributes better dimensional stability of the samples.
 When melamine adhesives are blended with UF adhesive, they
enhance the moisture-resistance properties of the UF adhesive
 All overlaid cardboard specimens showed higher thickness
swelling as compared to those of the cardboard specimens without
wood veneers
Discussion
Mechanical properties
 The 20% polyethylene in the cardboard process, polyethylene brings about
some elasticity in coverless cardboard more than wood based panels such as
particleboard, MDF, and OSB panels
 Cardboard samples overlaid using PU adhesive resulted the highest bending
strength characteristics among the other samples. Two-component PU adhesive
can be formulated for rigidity, depending on the degree of structural loading
required PU adhesive exhibits excellent joint strength
 The
weak adhesion between the cardboard and veneer because of the
inorganic materials such as aluminum particles and polyethylene in the used
beverage carton. This could be due to the high reactivity of isocyanates with the
inorganic materials of cardboard
Discussion
Mechanical properties
 Cardboards
with veneer sheets using two component PU adhesive can be
used in building construction and furniture industry as an alternative products
 Apolar aluminum particles on the surface of cardboard and polar structure
of veneer resulted in an excellent performance when polyurethane resin was used
as a binder. Surface bonding strength of the samples overlaid with UF, MUF and
PF adhesive was not as high as those of glued using PU adhesive due to nonporous structure of aluminum
 Cardboard
panels overlaid with veneer sheets using PU and PF adhesive
should be suitable for exterior applications
 Kraft paper used for manufacture of the cardboard samples caused higher
compaction than that of particleboard and MDF, aluminum content on the raw
material also enhanced the properties of the final product
Conclusion
Conclusion
 Raw
material from recycled cardboard was used for manufacture of
composite panels. Both physical and mechanical properties of the samples
resulted in satisfactory values meeting minimum requirements stated in EN 312
type 3 for particleboard, EN 622-5 for MDF, and EN 300 Type 3 for OSB.
 Wood
veneer faced cardboards had significantly higher mechanical and
physical properties than those of the wood veneer faced particleboards. This is
due to tighter profile structure and higher density of cardboard panels
 Panels made from recycled cardboard does not only have any formaldehyde
but also have very low resin content reducing overall production cost. Such
panels have certain amount polyethylene which does not contain any
formaldehyde. Cardboard panels could be used as an alternative substrate for
furniture production due to its formaldehyde free formation.
 Panels made from recycled cardboard have lower production cost than those
of wood based panels since raw material for cardboard panel manufacture is
widely available and has low cost as compared wood raw material
