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

Introduction

UBC can be recycled using a thermal compression process to manufacture home and

building products

Fig. 2 The dominating structure of aseptic beverage cartons

Polyethylene: barrier to moisture, bacteria

Paperboard: for stiffness

Polyethylene: adhesion layer

Aluminum: barrier to oxygen, light

Polyethylene: adhesion layer

Polyethylene: seals in liquid food contents

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)

Introduction

Developed by Tetra Pak®

UBC is produced in TurkeyUBC is produced in Turkey

Yekpan®

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.

• 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 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 :

DiscussionDiscussion

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 woo

d veneers

Physical properties

DiscussionDiscussion

The 20% polyethylene in the cardboard process, polyethylene brings about some elasticity in coverless cardboard more than wood based panels such as parti

cleboard, 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

Mechanical properties

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

DiscussionDiscussion

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 non-p

orous structure of aluminum

Cardboard panels overlaid with veneer sheets using PU and PF adhesive should be suitable for exterior applications

Mechanical properties

Kraft paper used for manufacture of the cardboard samples caused higher compaction than that of particleboard and MDF, aluminum content on the raw m

aterial also enhanced the properties of the final product

Cardboards with veneer sheets using two component PU adhesive can be used in building construction and furniture industry as an alternative products

ConclusionConclusion

ConclusionConclusion 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 p

articleboard, 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 t

o 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
