State of the Art Runi Trial Machine Has Now Arrived!

Following on from our blog back in February when the world was a different place, we are excited to have some positive news!  Our new Runi SK370 trial screw compactor has arrived and has already been put to work.

This is the latest model from Runi and as you would expect it has the same trusted Danish design and engineering alongside a new additional innovation – the force feeder or push press hopper.  This unique feature is a game changer for light, sticky, sloppy or difficult to process products.  The force feeder prevents material from bouncing on the screw by pushing it down into the screw chamber where the liquid separation takes place.

The press can be delivered to your site, to allow you to trial your product at a time and place convenient to you.  When your trial is booked, we will arrange for our engineer to come to your site to set up the equipment and demonstrate how it works.  You will also receive advice on how to optimise the screw compactor when processing your product.


Depackaging and liquid separation is a key process in volume and weight reduction of waste products.  The process separates liquid from containers in order for the component parts to be recycled and reused.

The Runi screw compactor is most suited to packaged materials including:

  • Packaged food waste
  • PET bottles
  • Cans 
  • Tins
  • PE film
  • Cosmetics

Runi for Food Waste

The Runi dewatering/depackaging screw compactor has proven highly effective at separating food waste from its packaging.  The process that can enhance your AD plant producing an additional, valuable feedstock and reducing the weight and volume of the remaining packaging.

Trials have typically demonstrated a reduction in weight by 50%.

When processing 2.6 tonnes of food waste in plastic packaging, weight reduction was calculated at 54.7%.  This equates to 9 Dolav-type bins of waste being reduced to 2 bins.

Dewatering Organic Materials

If you are looking to process organic, fibrous material such as: raw food waste; fruits and vegetables; tobacco; manure; crops; paper and pulp then the Vincent Screw Press will be more suitable for you.

If you have a product that could benefit from being dewatered or depackaged, then please do get in touch to find out more or to arrange a trial.
