Purpose: This study aims to identify the criteria for selecting salt suppliers and propose a supplier selection framework so that the salt industry can buy raw materials according to the specified standards and prices. Theoretical reference: This research synthesizes supplier selection criteria from the literature. Method: A decision-making framework for supplier selection was constructed by integrating the AHP with TOPSIS. Data were gathered via interviews with salt industry professionals and from observations of salt manufacturing and the supply chain. The weight of the criteria for selecting the salt supplier was determined through the use of questionnaires that utilized the AHP and TOPSIS methodology. Result and Conclusion: The findings of this study offer the Salt Industry valuable insights into the factors that should be considered when selecting suppliers, such as Quality, Service, Delivery, Flexibility, and Responsiveness. The AHP method's outcome indicates that the criterion with the highest ranking is quality. The results suggest that the criteria are ranked in descending order of importance, with quality having the highest weight, followed by delivery, responsiveness, flexibility, and service. Supplier A, with the highest ranking, has been chosen. Implications of research: The framework developed in this article uses only five criteria and was validated on one salt company. Further research can be continued by adding new criteria and validated in several salt industries. The algorithm and the output of this research are expected to be used as inputs in the design of the digital supply chain of the salt industry. Moreover, the management can use this method to choose raw material suppliers based on quality, service, delivery, flexibility, and responsiveness. Most producers of salt raw materials in Indonesia are salt farmers, most of whom still use traditional salt production and storage methods. It is hoped that the results of this research can provide information to salt suppliers, including salt farmers, about the criteria that must be met so that the salt produced can be immediately sold to the salt industry. Originality/value: This study develops a supplier selection system designed for the salt business, which has significant importance in Indonesia. The literature study results from this study are anticipated to provide valuable insights for academics researching supplier selection. This research can be furthered by examining the impact of this supplier decision on the performance of the Salt supply chain, extending from upstream to downstream.

Modern Geochemical and Tectonic Exploration—The Key Factor in Discovering the Northern Copper Belt, Poland

The discovery of the Northern Copper Belt in SW Poland is a result of an extensive exploration project with a key role played by various science-related methods. The project relied on mapping the distribution of mineral zones in the entire Fore-Sudetic Monocline, a unit known for its occurrences of Cu-Ag orebodies. This approach involved the examination of historical drill cores from over 400 oil and gas holes in this area, with the collection of samples for laboratory analyses. A close relationship was confirmed between the distribution of orebodies and the transformation of organic matter. Rock-Eval pyrolysis was also performed on selected samples. The tests of rock specimens were accompanied by the reprocessing of historical gravimetric and seismic surveying results. Field magnetotelluric surveying was also performed in certain areas. This phase resulted in the identification of areas with a high probability of finding the best ore, allowing for the initiation of the drilling stage. So far, 37 exploratory boreholes have been drilled in those locations, nearly all of them with highly positive results. The Northern Copper Belt consists of three deposits, Nowa Sól, Mozów, and Sulmierzyce North, along with numerous prognostic areas distributed therebetween. The future production of copper, silver, and the accompanying valuable elements presents a chance to provide the whole of Europe with a new plentiful supply of those critical raw materials.

Availability, distribution and quality of agro-industrial byproducts and compound feeds in Ethiopia

Livestock production is a major contributor to the national economy in Ethiopia, of which ruminants, particularly cattle, are the dominant and most important livestock species. Limited supply of quality feeds is a major constraint to the improvement of livestock production in Ethiopia. The expansion of agro-industries in Ethiopia, over the last three decades, has created an opportunity for an increased supply of agro-industrial byproducts as a source of feed for livestock. This study was conducted to assess the availability, distribution, and quality of agro-industrial byproducts and compound feeds in Ethiopia. About 310 flour mill factories, 194 oil factories, 13 brewery factories, 7 sugar factories, 4 malt factories, 2 meat and bone meal processing plants, 8 limestone factories, and 112 feed processing plants were surveyed to assess the availability and distributions of agro-industrial byproducts and compound feeds. A total of 757 feed samples were collected for evaluating nutritional values. The annual production of agro-industrial byproducts ranges from 18,065 tons DM/year (abattoir byproducts) to 3,092,035 tons DM/year (malt byproducts) and the total annual production of the different agro-industrial by-products amounts to 5,245,854 tons DM. The annual production of compound feeds was reported to be 5,812,608 tons DM. All agro-industries are processing under their capacity, ranging from 11.7% in sugar factories to 93% in breweries. Shortage and seasonal fluctuation of supply of raw materials (34.8%), high price and price fluctuations of raw materials (17.5%) and electric power interruptions (17.5%) were the major challenges faced by different agro-industries. The crude protein (CP) concentrations of agro-industrial byproducts ranges from 6.2% in maize grain screening to 15.9% in wheat bran for flour mill byproducts; 28% in cotton seed cake to 49.7% in groundnut cake for oilseed cakes and 14.8% in areqe atela to 24.8% in brewery spent grains for brewery and local distillery byproducts. High protein or energy contents of agro-industrial byproducts indicated their potential to be utilized in intensive livestock rations. Thus, it is necessary to create enabling conditions to allow the existing agro-industries to operate at full capacity and to attract new ones into the business to boost the production and availability of agro-industrial byproducts needed as main inputs to manufacture compound feeds.

Critical Raw Materials Supply: Challenges and Potentialities to Exploit Rare Earth Elements from Siliceous Stones and Extractive Waste

Critical raw materials (CRMs) supply is a challenge that EU countries have to face, with many thinking about domestic procurement from natural ore deposits and anthropogenic deposits (landfills and extractive waste facilities). The present research focuses on the possibilities linked to the supply of CRMs and the potential for exploiting rare earth elements (REEs), investigating a large variety of extractive waste and siliceous rocks in the Piedmont region (Northern Italy). Indeed, the recovery of REEs from the extractive waste (EW) of siliceous quarries and other siliceous ore deposits can be a valuable way to reduce supply chain risks. Starting with a review of the literature on mining activities in Piedmont and continuing with the sampling and geochemical, mineralogical, petrographic, and environmental characterization of EW facilities connected to siliceous dimension stones, of kaolinitic gneiss ore deposits, and of soils present near the investigated areas, this study shows that the degree of REEs enrichment differs depending on the sampling area (soil or EW) and lithology. The concentration of REEs in the EW at some sampling sites fulfils the indicators of industrial-grade and industrial recovery; the high cumulative production and potential market values of EW and the positive recovery effects through proven methodologies indicate a viable prospect of REE recovery from EW. However, REE recovery industrialization faces challenges such as the difficulty in achieving efficient large-scale recovery due to large regional differences in REE abundance, the mismatch between potential market value and waste annual production, etc. Nonetheless, in the future, EW from dimension stone quarries could be differentially studied and reused based on the enrichment and distribution characteristics of trace elements. The present paper shows investigation procedures undertaken to determine both CRMs potentialities and environmental issues (on the basis of literature data employed to select the more-promising areas and on sampling and characterization activities in the selected areas), together with procedures to determine the waste quantities and tentative economic values of REEs present in the investigated areas. This approach, tested on a large area (Piedmont region), is replicable and applicable to other similar case studies (at EU and non-EU levels) and offers decision makers the possibility to acquire a general overview of the potential available resources in order to decide whether and where to concentrate efforts (including economic ones) in a more detailed study to evaluate the exploitable anthropogenic deposits.
