“…The sampling procedure in the SAFINA company in the Czech Republic [9] is shown in Figure 1C and can be described as follows. The precious metal-containing material is first pre-treated and subsequently homogenized into suitable batches for subsequent sampling.…”

“…The copper and nickel contents in four representative samples of WPCBs after open conventional digestion were determined using the AAS method in two grain-size fractions, less than 1250 μm and less than 1000 μm. The results were statistically evaluated in the literature [14], and [15]. The contents of copper, lead, nickel, and zinc in WPCBs from discarded mobile phones were determined.…”

Waste printed circuit boards (WPCBs) from discarded mobile phones and smartphones are considerably heterogeneous materials with a high gold content (approx. 490 grams per ton). The aim of our chemical analysis of samples of WPCBs was to determine the amounts of gold using open acid digestion and atomic absorption spectrometry (HR CS AAS). The test samples designated for chemical analysis must genuinely represent the bulk WPCBs from which they are taken. This study aimed to develop a correct sampling procedure to analyze the heterogeneous materials from printed circuit boards; explicitly concerning the influence of particle size on the precision of chemical analysis of WPCBs from discarded mobile phones. Chemical analysis of the representative sample of WPCBs with a grain size fraction of d ≤ 200 μm determined that the gold content was 475 g∙t-1 with a low variation coefficient and low dispersion which indicates very high accuracy of the designed sampling procedure.

The aim of this article is to provide analysis and description of deposit and recycling system of disposable beverage packaging, which started in the Slovak Republic in 2022. The article provides the review of relevant literature with a focus on circular economy and Deposit Refund System (DRS), where analysis of refund systems was performed for this work. The proposed model involving reverse logistics describes how such deposit and collection system can work in practice, highlighting potential disadvantages, mainly the high investment costs. Therefore, the article also includes a financial analysis exploring potential cost of establishing said deposit and collection system. The number of necessary collection point for Slovakia has been determined and the total investment costs for the vending machines installations and service in Slovakia has been calculated.
