- a step of the method according to the invention consists in providing 200 a set of unitary waste 1.
- unitary waste is meant a waste as such or a fragment thereof when the method according to the invention implements in addition at least one preliminary step 199 of grinding the unitary waste.
- the unitary waste 1 may be of the same nature, or heterogeneous, that is to say of different natures, from different sources of raw material.
- one or more grinding stages make it possible on the one hand to release the various materials constituting certain complex waste, and on the other hand to reduce the particle size of the waste.
- the unitary waste 1 is then conveyed 210 by convoy means 2, on which they are placed, to unitary analysis means for analysis step 220.
- the analysis means comprise means of analysis.
- the convoy means comprise for example a conveyor 2, driven by a translational movement, illustrated by the arrow ( Figure 1), preferably at a constant speed.
- the distribution of the unitary waste 1 on the means of convoy can be random.
- the electromagnetic analysis means 3 may be of different types, possibly multiple, as described later, and are preferably configured to analyze the waste individually, unitary waste per unit waste.
- a type 3 'of these electromagnetic analysis means is such that they are configured to be able to implement a step 240 of determining the nature of said unitary waste.
- Another type 3 "of these electromagnetic analysis means is such that they are configured to be able to implement a step 250 of analyzing the shape of the unitary waste.
- the step of determining the nature of the waste 240 makes it possible to determine the constituent material of the waste, that is to say of its main constituent (paper, wood, cardboard, plastic, type of plastic, etc.).
- the step of determining the nature of the waste 240 is carried out at least by electromagnetic means 3 '.
- the nature of the unitary waste 1 is determined for example by optical means 3 'configured to perform a spectral analysis of the light reflected by said unit waste when it is subjected to a suitable and sufficiently intense illumination.
- This spectral analysis is conventionally used in automatic waste sorting machines.
- the studied spectrum is that emitted in the near infrared.
- the step of determining the nature of the waste 240 makes it possible to determine whether the unitary waste is based on paper, wood, plastic, etc.
- the method according to the invention further comprises a step of analyzing the shape of the unitary waste.
- optical means 3 preferably operating in the visible range, provide an image, preferably in plan view, of the unitary waste.
- 1 is accessible for example via a digital camera as illustrated for example in the application WO 2005/028128, or even by adhoc processing of the signal used for the aforementioned spectral analysis.
- the optical means 3 'and / or 3 " are designed to have a field of vision encompassing the entire width of the conveyor 2, and configured to be able to identify and analyze independently of each other the different unitary waste 1 possibly present in their field of vision.
- the shape image of each of the unitary waste 1 is processed by calculation means, in this case a calculator 4 which determines in particular the contour, the area and the factor shape (ratio length / width of the smallest rectangle in which the contour of said unitary waste 1).
- the method further comprises a step 230 of determining the biogenic carbon content of the unit waste.
- the determination of the biogenic carbon content of the unit waste can be carried out by means of the analysis step 220. It is carried out by measurement or by estimation, by means of analysis and calculation described hereinafter.
- the determination of the biogenic carbon content of the unit waste is carried out by estimation.
- the biogenic carbon content of the unit waste is determined by comparison with reference values of a reference database.
- the reference database makes it possible, in particular, to associate with each nature or material of unitary waste, the physicochemical characteristics which are peculiar to this nature, that is to say, without this list being limiting, density. , total and biogenic carbon content, calorific value, ash content, etc.
- the reference database stores a reference model comprising, for each type of waste, the mass and / or the biogenic carbon content of said waste for a given area (form factor).
- Calculator 4 receiving information on the nature of the unitary waste, and its area or form factor
- the thickness of said waste being known or approximated, interrogates the reference database 5 and receives in return the specific characteristics of the corresponding material / nature. It then affects these characteristics and the coefficient biogenic carbon content / area or form factor to be applied to said unit waste to deduce the content (ie mass) biogenic carbon of said unit waste 1, which allows advantageously not requiring a step of measuring the mass of each unit waste.
- the unitary biogenic carbon content of a unit waste can be stored and summed to calculate the total mass of biogenic carbon of a batch of unitary wastes.
- each fragment ie to each unit waste, a statistical distribution, obtained by the experiment, of the masses of fragments of the same material and the same dimensional aspect (area and ratio length / width of the rectangle envelope comparable).
- This statistical distribution possibly stored in the reference database, or another database, makes it possible, for example, to estimate the thickness of said waste, and also the mass (or the biogenic carbon content) of each of the unitary waste. from the knowledge of its nature (the constituent material) and the vertical projection of its outline on a plane horizontal. It also makes it possible to evaluate the uncertainty on this mass determination from the characteristics of the distribution (variance, standard deviation).
