It might look simple – but it isn't


The principle is simple: a liquid is developed to penetrate
between the layers of a multi-layer system and "burst"
this open, separating the individual layers. However,
the art lies in the "composition" of this magic liquid…

Separating composite materials using micro-emulsion


Saperatec develops highly specialised micro-emulsions based
on surfactants. Surfactants are known for reducing surface
tension. The micro-emulsion then channels its way between
the layers of the composite material, where its full effect
unfolds, resulting in the separation of the composite.

The separation process

The entire process for obtaining saleable products from composite waste is as follows:

01 CRUSHING

The first stage is to reduce the size of the material to create as much contact surface for the micro-emulsion as possible and to simplify material handling in the process.

02 SAPERATEC MICRO-EMULSION

The core process involves treating the shredded composite material in the micro-emulsion. The separation process is conducted with stirring and at a low temperature (ca. 40°) and finally the individual fractions ("products") appear in the micro-emulsion.

03 WASHING

First the products are filtered out and the micro-emulsion is reconditioned. Then the products are cleaned with washing water and the washing water is also reconditioned.

04 SORTING

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

05 DRYING

Another final drying is required, if necessary, to make the products saleable.

Applications

APPLICATIONS

The procedure involves a platform technology that can be used for recycling a wide range of materials.

Used beverage cartons
Paper | Plastic | Aluminium

This practical drinks packaging that has been used billions of times over is a composite composed of three different materials, and 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 | Semi-conductors | 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 raw materials used will then have to be reclaimed. 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!

The benefits

Five benefits in one go

No incineration
Max. added value
as the raw materials used are reclaimed
Low energy consumption
as the procedure functions well at room temperature
High purity
of the raw materials obtained
Reusable
The micro-emulsion is reconditioned and reused

Recovery of raw materials

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

Win-win situation

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