Applications:   Molded Fibre

Enhanced end-products


The addition of engineered fibres to the usual waste paper furnish can bring benefits in end product properties – increase in bulk and tensile strength, increase in compression strength.

We can engineer either a waste fibre source or a virgin fibre source to give extra properties, having no impact on the usual production process.


Use Alternative Fibre sources


The processes developed by ZT render a wide range of agro-residues or by-products, such as flaxes, straws, stems from various plants as suitable for use as feedstocks for Moulded fibre products.

This not only allows Pulp Molders to reduce their dependence to waste paper prices, but also to offer their clients the possibility of using their own waste!


Product development and Small Series


The ZT Technical Centre has direct processed fibre to test moulding capability. ( contact ) 

Applications:   Paper & Carton-board

Increase inner strength & compression strength


The addition of engineered fibres to the usual fibre furnish can bring benefits in end product properties – noticeable increase in Scott Bond & SCT tests, increase in tensile strength.

The extent of the improvement depends on the quality of the Engineered Fibre used  (ZT has experience with both recycled and virgin fibres) and on the degree of de-fibrillation applied.


Opacity & porosity


Another set of properties that can be modified in the end product’s opacity and porosity. The addition of Engineered Fibres will great decrease the porosity whilst increasing the paper’s opacity.

This has applications in the specialty papers & packaging.

Applications:   Fibreboards

A unique binder-free fibreboard


The fibreboards composed of self-binding Engineered Fibres are free of any additional binder and rely solely on hydrogen bonds between fibres.

From low density (0,4 g/cm3) insulation panels to high density (1,5 g/cm3) laminates, all boards produced with processes developed by ZT are VOC free and contribute to the improved quality of air in any given environment.


Upcycling opportunities for mixed waste


Numerous mixed wastes (waste paper contaminated with plastics) are either burnt or sent abroad – and the latter will not always be the case, as recent events have shown.

The flexibility of the ZT process allows us to upcycle these materials (up to 15/20% plastics is acceptable).

Source Materials

Material Palette: Infinate Possibilities

Globally sourced agricultural waste, residual fibre packaging, panels/laminates

Agricultural New and Residual Fibre sources:-

Bagasse, Sawdust, Pin Chips (wood), Cotton waste, Cotton Bush, Hemp Hurds and Waste Fibre Kenaf, Coconut (Coir), Pineapple, Palm, Banana, Water Hyacinth, Seaweed, Bamboo, Reeds, Grasses.


Industrial sources:- De-inking sludge, paper and board mill waste fibre streams, offcut cellulose and textiles.


Post Consumer Sources:- Recycled paper and packaging materials.


Processed cellulose:- Bleached and unbleached wood and non-wood pulps.


Mixed wastes:- Contaminated Waste Paper, Cups, etc…


Where appropriate, the processed fibres can be combined with mineral fillers, synthetic fibres as well as with natural binders. 

Our clients generally specify their particular target source fibre, although Zelfo Technology can assist a client to make this choice.

Do not hesitate to contact us should you want to test your own material.
