Purchase, separate sorting and recycling of electronic scrap
Nature of electronic scrap
In recent years, we have seen exponential growth in the electronic equipment market, and this means, respectively, that as a result of the use of these products, the amount of waste they generate also increases. The global business faces a new problem called e-waste.
Electronic scrap includes all waste materials and elements, which at the beginning of the production cycle of electronic devices are a building block, and after a certain operational period become waste. Very often this type of waste is landfilled or incinerated instead of being recycled. This means that tons of toxic substances such as cadmium, lead, and mercury are released into the air every day and cause serious damage to the environment and human health. At the same time, extraction of valuable metals contained in electronic scrap – gold, cobalt, palladium, platinum, and others – is hindered and their reuse cannot be realized. This leads to both financial losses and disruption of the natural environmental balance of these exhaustible resources.
The need for e-scrap recycling
The recycling of electrical and electronic waste is becoming more and more relevant with the amendments to the European standards in this area, which means that all manufacturers, importers, traders and users of electrical and electronic products must reorganize and finance the processes accompanying the recycling of this type of waste. It is necessary the thinking of the masses to be oriented towards the protection of the environment in order to reduce the volume of waste and preserve valuable natural goods and resources. Let us bequeath to future generations both a large amount of valuable natural resources and the know-how of good practices in their repeated use!
Purchase and recycling of all types of catalyzers
-
The installation of catalytic converters in cars aims to reduce harmful substances in car exhaust gases. Thanks to the catalytic converters, the oxidation of carbon monoxide, hydrocarbons and nitrogen oxides was achieved. The legal regulations affecting the exhaust gases are becoming stricter and this requires the continuous increase in the efficiency of the converters, which respectively leads to the use of a greater amount of metal substrates. At the same time, large quantities of precious metals such as platinum, palladium and rhodium are also required for the production of catalysts.
There are two types of catalysts:
– Ceramic substrate – it has a honeycomb structure; the exhaust gases pass through the coated channels and reach the precious metals;
– Metal substrate – it is made of a flat, corrugated metal sheet; the sheets are arranged in layers and rolled into a cylindrical or elliptical shape, pressed into a metal casing and welded under high temperature.
Metal and ceramic monoliths differ in shape, size, weight, and amount of precious metals, as their different models suit the distinct advantages of the two techniques, necessitating different approaches to recycling these components.
Recycling of catalyzers
Historically, the main incentive for recycling catalysts has been the revenue from the high-value platinum group precious metals recovered from the monoliths. The value of scrap catalysts varies depending mainly on the type and size of the precious metals recovered.
Since precious metals are only available in certain parts of the catalyst (mainly in its coating), the process of recycling catalysts is long and complex, consisting of several stages, and high-level professionals are needed for its implementation. Thanks to our many years of experience in the field and our highly specialized cooperators, we offer the implementation of the entire process from its very beginning to its end.
Catalyst recycling stages
-
- Mechanical separation of precious metals and coating from the substrate, which is key to determining the value of recycled lots. The results of this analysis are used in determining the price with the supplier. Thanks to this procedure, it is possible to extract both the coating and the precious metals in it, as well as the steel fraction.
- Separation of the residue of precious metals on the substrate film from the steel parts in a mechanical way. This process is carried out by means of a hammer mill and air separation.
- Separation of different fractions, coating with precious metals, substrate sheet and body, which go to further processing.
Our specialists implement the process of recycling catalytic converters in a way that fully complies with environmental protection standards!
