Alternative Fuels

The brains behind Systems 4 Recycling have been developing RDF Production Systems since 1996. Having previously developed and installed the largest waste-to-energy site in Europe, our staff really do have the knowledge behind what works and what doesn’t.

We can integrate with existing processing plant or look at a blank sheet to design and develop with you a system which will not only produce high quality RDF but also maximiseyour recyclatesrecovery too. Our designs incorporate ease of maintenance and maximum production availability – we can even keep systems producing, albeit at reduced capacity, when shredding lines are down for servicing or maintenance.

Maybe you are a fuel user and need the cleanest and most efficient means of RDF storage, handling and blending? Perhaps you are the new RDF producer – our customer, who has now ventured in to the world of energy production by gasification? Either way, we have the systems and know-how to ensure the maximum efficiency in this ‘up-time’ oriented area.

From storage to blending and conveying at high capacities, we can design and build a system to suit your needs whilst delivering a high level, reliable and consistent performance.

We also offer very clean systems, with virtually dust free truck unloading, to sealed storage and enclosed and automatic truck loading docks, therefore not only offering a clean working environment but vastly reducing the risk of any cross-contamination with the fuel.

Whilst we have systems in operation running well on MSW material streams, without drying facilities the realisation of waste as RDF can be, whilst successful, quite limited. Over the years we have worked with the leaders in two areas of material drying and offer both fully enclosed in-tunnel systems and fully covered membrane technology.

Both processes work on the aerobic basis – i.e. utilising the heat produced by mesophyllic and thermophyllic bacteria – in order to heat up and therefore dry material. This means that operating costs are low as no additional heat is required to be added to the process. Drying times of 7-10 days (pending waste morphology) can be realised and with efficient bio-filters, all odours are well controlled and virtually eliminated.

The end result is a good conversion rate of MSW waste to RDF with low moisture content as well as the high calorific value and low chlorine content we have already perfected in our systems.

The specification of RDF you produce will be determined by the fuel user for quality and size – including density and form. Additionally, if you’re planning to ship RDF overseas then maximising weight on transport is key to the financials. This is where densification comes in.

Pelleting systems have been around for many years and are proven. However, cubing offers many benefits, including much lower capital investment due to the fact we can cube material at <80mm and operational costs about half that of a pelleting system.

We have been working with cubing systems for almost 15 years now and have perfected machines which will densify light fraction for RDF from many waste streams along with energy crops such as miscanthus which can prove very difficult to process mechanically due to its abrasive nature.

Our systems offer the flexibility to produce cubes of varying density to suit the end user and can run continuously and reliably at throughputs in the region of 5-7 tonnes per hour.
