It might look
simple – but it isn't

The principle is simple: a separation liquid is developed to penetrate
between the layers of a multi-layer system. The liquid breaks this
system up separating it into individual layers. and “burst”
this open, separating the individual layers. However,
the trick is in the “composition” of this magic separation liquid.

Separating composite
materials using
separation liquids

saperatec develops highly-specialized separation liquids based
on chemical mixtures for different applications.
The separation liquid channels its way between
the layers of the composite material, where its full effect
unfolds, resulting in the separation of the composite.

The separation

The entire process for recovery of obtaining saleable products <br>from composite waste is as follows:


The first stage is to reduce the size of the material to create as <br>much contact surface for the separation liquid as possible and to <br>simplify material handling during the process.


The core process involves treating the shredded composite material <br>in the separation liquid. The separation process is <br>conducted by stirring and warming up until the individual fractions<br> (“products”) are completely separated.


First the products are screened out and the separation liquid is<br> reconditioned. Then the products are cleaned from <br>adhesions of chemicals with washing water<br> and the washing water is also reconditioned.


The now clean products are sorted using conventional procedures<br> (float-sink, sifting, …) and obtained individually.


Another final drying and occasionally follow-up treatments<br> are required, if necessary, to make the products saleable.


separation potential

The procedure is a platform technology that can be <br>used for recycling a wide range of materials.

Used beverage cartons

Paper | Plastic | Aluminium
This practical beverage carton that has been used billions
of times is a composite of three different
materials, whereby separating plastic and aluminium in
particular has long been an unresolved challenge.

Packaging material

Aluminium | Plastic
Nowadays packaging should be light and functional. Therefore, it
increasingly consists of several materials. Examples include
packaging for dairy products,
coffee, confectionery, fresh products, cosmetics, pharmaceuticals and even pet food.

PV modules

Glass | Semiconductors | Plastic
The number of PV modules that have been mounted on roofs in just a few years is a real achievement, but at some stage they will become waste. The used raw materials will then have to be recycled. We make this possible by separating modules into individual components.

Li-ion batteries

Aluminium | Lithium metal oxide |
Graphite | Copper
Alongside modern electronics, these high-quality batteries are the driving force
behind electromobility. The valuable
metals such as lithium, aluminium and copper can only be reclaimed when the coiled layers are
separated again.

Car glass

Glass | Plastic
Car glass is a “sandwich” of two panes of glass with an adhesive plastic film in the middle. This film is of very high quality and can be reused after separation, just like the glass.

Something else you want to separate?

Do you have other interesting applications? Or do you have a specific task in mind involving the separation of a
composite material? Then we look forward to hearing from you!


Five benefits in
one go

No incineration

Maximum added value

as the used raw materials are recycled

Contribution to environment

due to advantageous eco-balance of the process

High purity

of the obtained raw materials


as the separated liquid is<br>reconditioned and reused

Recovery of
raw materials

By separating disused composite materials, the used raw materials
can be reclaimed as secondary raw materials,
thus fully preserving the cycle of materials – true sustainability!.
This is sustainable.


 … due to the sale of valuable secondary raw materials  and image enhancement!
