Shredder tailored to organic waste

What is your product?

A customised Untha RS40 for organic waste shredding.

How does it work?

This specially-configured four-shaft shredder draws organic waste into the cutting chamber, pre-shredding and re-shredding it in one single process. Innovative tooth and cutting gap geometrics mean food waste and packaging can be processed to ensure the right fermentation substrate for anaerobic digestion (AD).

Where would it ideally be used?

In food waste and AD plants, or by organisations that produce food waste.

How is it different?

The cutting system is tailored to organic waste to optimise the machine’s performance at the same time as achieving the required particle size.

The shredder’s mechanical seals stop the ingress of liquids that would otherwise corrode parts. Wear plates are fitted as standard, which means only simple components have to be replaced.

What benefits does it offer?

The design features mean the RS40 achieves unmatched productivity and uptime. Its throughput is 10-12 tonnes an hour, depending on the density and moisture content of the waste. Operating at 80dBA, the RS40 is the only noise-compliant shredder of its kind in the marketplace.

What about maintenance?

The machine needs minimal maintenance. Its integrated lubrication system, for example, keeps the bearings well greased. This negates the need for users to remove machine covers.

Where has it been used?

We have worked with at least 50% of the UK’s food waste plants including Fernbrook Bio, Lower Reule Bioenergy and Langage AD.

Cost?

The range is available from £30,000, with flexible finance options.

What is its life span?

The contents of waste streams can never be guaranteed - a metal component could easily end up in restaurant food waste. The RS40’s foreign object protection system acts as a ‘quality control’ mechanism, preventing machine damage and safeguarding investment longevity. 

Any future applications?

As the AD marketplace evolves, this flexible shredder will increasingly be used to separate food waste from recyclable packaging materials such as tin cans, plastic packaging or food waste collected in corn starch bags. 

How many have you sold and where?

There are more than 450 RS40s in the UK, 20 of which have been specifically configured for this niche area of food waste processing.
