COLLECTION
Rizzinox offers its suppliers the service of collecting scrap metal directly from their premises, relieving them of the burden of organising transport, guaranteeing punctual collection and adequate transfer of the goods, in full compliance with current legislation.
Rizzinox's fleet of vehicles includes articulated trucks and lorries, with and without cranes, offering maximum flexibility and adaptability to meet any requirement for space, quantity and quality of materials to be transported.
The collection or delivery of the various materials to our plant can be carried out in accordance with European Regulation 333/715, i.e. with a transport document and declaration of conformity, or with a Waste Identification Form in accordance with our Ordinary Authorisation.
ANALYSIS
Rizzinox is able to thoroughly check and analyse the materials delivered to us in order to ensure the most advantageous quotation for our suppliers and the best possible quality of the material supplied to our customers.
When the material is unloaded, an initial check on the type and quality of the material is carried out using portable Niton XL2 800 Plus analysers from Thermo Scientific, which allow an initial assessment of the type of material and its chemical composition.
These analysers are based on the photoelectric effect, that is the physical phenomenon for which a surface, usually metal, emits electrons when it is hit by an electromagnetic radiation; in this case the radiation produced by the X-ray tube of the device hits the surface of the material to be analysed and the detector reads the kinetic energy of the ejected electrons, measuring this energy it goes back to the binding energy that is indicative of the chemical element concerned. This technique only allows an analysis of the surface layers of a solid material.
A more in-depth and accurate analysis of the chemical composition is carried out in our analysis laboratory by means of an Ametek SPECTROMAX X spectrometer, which uses the principle of atomic emission spectrometry based on the analysis of the characteristic light spectrum emitted by excited metal atoms.
Spark spectrometry is particularly suitable for the analysis of metals and metalloids, and is able to guarantee a high degree of precision that can reach the order of one part per million; by exploiting a spark, the atoms of the sample to be analysed are vaporised, the electromagnetic radiation generated is conveyed to the spectrometer optics, directly or by means of an optical fibre, where it is divided into the different wavelengths that make up the spectrum: by analysing it, the quality and quantity of the elements that make up the analysed sample can be traced.
CONTROLS
Rizzinox pays particular attention to the environmental aspects of its work and is constantly seeking to optimise processes and innovate equipment to ensure that all operations are carried out more efficiently and in full respect of the environment.
Radiometric monitoring plays a major role in environmental protection: all the material passing through our warehouse is subjected to a careful radiometric check which, for incoming and outgoing loads, is based on the use of a fixed radiometric portal through whose panels the vehicles loaded with material pass, so that they can be probed for any radiogenic sources.
A further check is carried out after unloading, while the material is still on the ground, by means of a portable detector, thanks to which the operator can carry out a series of close and punctual checks on the entire load.
The results of each of the above checks are recorded and stored in accordance with the provisions of the regulations in force and in accordance with the guidelines contained in the internal radiometric monitoring procedures drawn up by a qualified radiation protection expert.
