The Recycling Hybrid 

About

About

The Sentrec 3 Hydro Centrifugal Separator is almost here! After 10 years of improving and simplifying the first and second version we feel it's time to develope one that can help the world of recycling even more.

The Sentrec separator was developed originally for separating LDPE from Cable regrinds. 
This mixture of PVC, Rubber, LDPE, Copper and Aluminium is especially challenging due to the fine grain size ( from 0,1 mm to 1 cm ).  

  

Where a normal swim sink tank could not get us the PVC free quality we needed, and the 3-way decanters were to costly in investment and maintenance, we knew we had to come up with a devise that could combine both techniques

The overall design, based on years of hands on experience, makes the separation of plastics easy, fast and precise. Saving time, money, and still get a superb result. 

 

So, after extended re-designing.....

We produced a perfectly working prototype, with an over 99,5% separation output.

And build a 3 meter wide one to test the version 3 technology on a full scale

Why choose Sentrec
Case studies

Case Studies

LDPE CABLE REGRINDS

Target:    Extract a clean LDPE out of a mix of PE, PVC, Rubber, Copper and Aluminium. 

Medium:   Water

Difficulty: Very fine granules

Input mix 20/1

Result: 99.8% LDPE

MAS SYSTEM FILM WASTE

Target:    Washing this mix of ldpe foil and about 30% heavies 

Medium:   Water

Difficulty: Viberous and fine ldpe

Input mix 15/1

Result : we managed to extract the ldpe clean enough to reprocess and turned back into bin bags

WHEELYBIN GRINDING DUST

Target:    Washing the HDPE rich resi

Medium:   Water

Difficulty: Viberous and fine ldpe

Input mix 25/1

Result : we managed to extract the HDPE clean enough to agglomerate and to be mixed back with the Wheelybin Regrinds

PET FINES WITH 4% HDPE

Target:    Washing out the HDPE

Medium:   Water

Difficulty: Very small particles

Input mix 

Result : 

PO LABELS / BOTTLE CAP / PET

Target:    Washing out the PET

Medium:   Water

Difficulty: Mix of film and regrind therefor fast and slow sinking properties.

 

Input mix 25/1

Result : We've been able to extract the PO mix up to 99,8%

So why do we need you ?
 
Uptil now all test but one have proven succesfull;
The separation of even small microplastics
The volumes per hour
The extremely low energy consumption
The only thing that was differend from the small prototype was the water consumption on the sinking part of the machine.  Ideal would be 85% water for the floating particles ( Polyolifines )  and 15% for the sinking particals.
The full scale Sentrec is using 85% for the sinking fraction which is far from ideal.
In order to fix this, the Sentrec has to be re-designed and rebuild and made ready for the market, get CE approval and to test it through and through to make sure we have a quality product.
We have learned a lot from the full scale machine and all knowedge gained will come to good use in the final Sentrec 3 system.
