Sampling secondary materials, recycling success
The process of sampling secondary materials is essential for the various technical-economic decisions. Indeed, upon leaving the sorting centers, these secondary raw materials can be exploited again, for better recycling of resources.
Sampling secondary materials for successful recycling is important to reduce pollution. It now appears that recycling has become a central concern for many stakeholders. Consequently, it tends to become industrialized to increase its efficiency.
It must indeed be admitted that the slightest error in any waste management estimate could lead to significant financial losses. This could also generate some ambiguity regarding the operational process already implemented. It is of particular interest to the scientific and technological sectors for various reasons. It affects, among other things:
- Mining
- Mineral processing
- Metals
- Cement
- Recycling electrical waste
- Human and animal nutrition
- Agriculture and aquaculture
- Pharmaceutical products
The objective is mainly a matter of bringing together the main academic and industrial players wishing to compare their experiences. It will be a question of addressing the issue relating to sampling together.
Discover the theoretical developments of sampling theory
The recycling of waste likely to become raw materials again is currently at the heart of concerns. This undeniably involves the fragmentation and sampling of matter. The main players in waste treatment have the opportunity to discover the different developments in correlation with the theory of sampling.
For true recycling success, it would be necessary to go through this stage of sampling secondary raw materials. This is a process similar to sampling primary raw materials. Mastering these techniques would indeed make it possible to successfully implement the steps put in place for the success of various recycling projects. This area therefore presents itself as a great challenge.
It is crucial to know the basics and theoretical advances of the principle of sampling. You can learn about good practices in recycling materials, soils and sediments. But also discover the changes taking place at the level of urban mining, particularly concerning the recovery and recycling of recoverable metals and minerals.
A brief overview of what we mean by recycling of secondary materials
In recent decades, the quantity of household waste has increased exponentially. Urbanization is one of its main factors. This remains even more obvious in developing countries. Likewise, the composition of this waste has moved from an organic profile to increasingly complex materials, as can be the case with plastics, end-of-life electronic devices and packaging. They represent significant risks for the environment and for our health.
Recovery has therefore become a major pillar of waste policy. In terms of the circular economy, recycling presents itself as a process contributing to the economy of raw materials. It would effectively reduce the pressure on non-renewable materials.
We see in the development of recycling sectors a great desire to ensure more coherent and more efficient waste management. Regarding secondary raw materials, if their recycling is well managed, they will be able to limit the use of virgin raw materials, by being effectively reused by companies.
Detailed waste management objectives
If the sampling of primary raw materials did not take long to take off, it took some awareness for this sampling process to also apply to materials of secondary origin. With recycling starting to become more and more industrialized, the various players have no room for error. They must indeed manage these processes well in order to achieve complete recycling success.
Waste management experts have covered the basics and foundations of the principle of sampling secondary materials before moving on to the developments and practical cases which are beginning to become more widely available. This may, for example, concern experiments carried out in deposits or other environments. We can thus cite river zones, polluted soils, marine sediments, old industrial sites and waste linked to electronic cards or even WEEE.
Here is a short summary of the recent conferences talks on this topic:
- A general introduction to sampling
- A theme on the sampling of marine and river sediments
- Characterization and analysis of higher particle size fractions in polluted sites and soils
- Geostatistics applied to polluted sites and soils: from sampling to decision-making
- Collectors or samplers: How to make the right choice?
- Cullet sampling before and after treatment
- Representative sampling of waste using rare particles in concentration and size
- The challenges of urban mining sampling, special case of electronic cards
