Food waste valorization thanks to modular Archimedys screw conveyor

09 Jun 2017, by Vincent Tondeux in Archimedys Realisations

Sustainable development, pollution control and environmental protection are some of the major issues of the 21st century. Growth of the world population and world production induces a significant increase of waste. Waste management is becoming a real challenge for all companies, in all activity aeras.

Moreover, energetic transition process requires renewable energies development and control of energy consumption.

In such a context, companies must promote waste valorization, especially energetic valorization to deal with this issue.

The food chain produces a lot of organic waste which needs managing. Traditionnal ways of dealing with this waste are not sustainable. Hauling the waste from the point of production to centralised facilities adds cost and increases the carbon footprint of the waste.

That’s why one of our customer, SeaB Energy, a world specialist in green energy, has developed a containerised anaerobic digester which turns organic waste into free energy, right at the point where the waste is generated and the energy is required.

Thanks to this patented process, the organic waste fermentation produces biogas : the energy that remains in food waste is captured and used to fuel an engine to provide electricity and heat.

SEaB Energy chose to fit out its containers with our modular plastical Archimedys screew conveyor : indeed, setted at the bottom of the hopper, Archimedys screew conveyor has got many advantages.

With its simple and compact design, Archimedys screew conveyor is very light in weight in comparison to stainless steel conveyor : it can be easily handled and installed and it doesn’t make any noise during operation.

Moreover, Archimedys modules have got a particular geometry so that Archimedys screew can be used without any intermediate bearings.

Furthermore, due to its modularity, when the Archimedys screw conveyor needs to be repaired, you only have to change the damaged module and not the entire screw which also reduces maintenance life cycle costs.

Archimedys screew conveyor is made with a material which has such a high corrosion resistance that it can be used even in an abrasive environment.

Archimedys screw conveyor is a real technological revolution and received, in this regard, the Industrial Innovation Award in 2011.
