Alternative Fuels 

The Problem

There are many sources of information on the Internet about the amount if waste in the world. The number is extremely huge, probably beyond our imagination. 


Pictures of thousands of tons of PET bottles, plastic bags and boxes in the landfills, oceans and seas. There is more of it. 

Let's put it in other words: this all is a laying and floating energy. In the era of energy shortage leaving it all there is just a waste of energy, extreme pollution of many areas in millions of place in Earth. 

Despite of the growing amount of waste in the world there is no global solution for the management of waste. The higher consumption, the more garbage around us in every place in the modern world. And no solution so far...

The Solution​

It is easy: Make a fuel out of waste. 

People have all the technology we need to convert garbage into SRF or RDF. Then there is just one step away from creating a new fuel.

It is PELLETS - with all their advantages which are at least

  • easy feeding to furnaces,

  • easy dosage with full automation,

  • environmentally friendly, when properly used

  • stable components composition,

  • high calorific value.

SRF and RDF pellets are known for industry, where are widely used in cement kilns and some other applications. The point is to use them also in half-industrial furnaces and domestic.

Parameters of the feedstock


For the best results (optimal capacity and quality, low power consumption) the feedstock's parameters should not exceed the following:


  • moisture level: 15%

  • particle size: up to 10 mm (without extra milling).

  • no pollutions like metals, stones etc.

In case the particle size exceeds 10 mm - 15 mm we strongly recommend using the RS.R modules for fine milling. Especially when the pellets diameter is below 8,0 mm the pelleting process requires small fraction. Otherwise the capacity of pellet mills will drop, because part of the power would be consumed for size reduction during pelleting.

Pellet Mill

GRB2 850.320 ARGAS

Most robust pellet mill designed for hard feedstocks. The 850 mm die with 2 motors 160kW each gives from 3 tph to 4 tph of SRF/RDF pellets and about 2 tph to 3 tph ASR pellets. The capacity depends on parameters of the feedstock.

Standard equipment of pellet mills

  • pelleting press with main drives,

  • main drives 2 x 160kW,

  • 1 ring die fi850mm,

  • 2/3 complete rollers,

  • die replace supporting system,

  • pneumatic distribution system,

  • central automatic lubrication system,

  • electric hoist for dies and rollers exchange,

  • independent raw material feeder for a die,

  • inner magnetic separator,

  • barrel of grease 180 kg,

  • electric/signal box,

  • service tools kit,

  • set of sensors,

  • documentation (English),

  • conditioner KD stainless steel with a drive,.

Optional equipment of pellet mills


  • power cabinet with LCD panel,

Hammer mills

The RS.R module contains a hammer mill with the motor depending on the capacity and parameters of the feedstock.

We deliver hammer mills with power of 160kW, 250kW, 315kW and 400kW. There is a supporting construction for pneumatic transport system (cyclone, fan, tubes etc.), the collecting chamber with sucking tube.

Every RS.R Milling Module is equipped with destoner for removing unwanted particles like stones, metal parts or other heavy parts.
