Toward sustainable reprocessing and valorization of sulfidic copper tailings: Scenarios and prospective LCA

There has been increasing attention recently to reprocessing of mining waste, which aims to recover potentially valuable materials such as metals and other byproducts from untapped resources. Mining waste valorization may offer environmental advantages over traditional make-waste-dispose approaches. However, a quantitative environmental assessment for large-scale reprocessing, accounting for future trends and a broad set of environmental indicators, is still lacking. This article assesses the life cycle impacts and resource recovery potential associated with alternative waste management through mine tailings reprocessing at a regional scale. Sulfidic copper tailings in the EU were selected as a case study. We perform prospective life cycle assessments of future reprocessing scenarios by considering emerging resource recovery technologies, market supply & demand forecasts, and energy system changes. We find that some reprocessing and valorization technologies in future scenarios may have reduction potentials for multiple impact indicators. However, results for indicators such as climate change and energy-related impacts suggest that specific scenarios perform sub-optimally due to energy/resource-intensive processes. The environmental performance of reprocessing of tailings is influenced by technology routes, secondary material market penetration, and choices of displaced products. The trade-off between climate change and energy related impacts, on the one hand, and toxicity impacts, on the other hand, requires critical appraisal by decision makers when promoting alternative tailings reprocessing. Implementing value recovery strategies for building material production, can save up to 3 Mt. CO2-eq in 2050 compared to business as usual, helping the copper sector mitigate climate impacts. Additional climate mitigation efforts in demand-side management are needed though to achieve the 1.5 °C climate target. This work provides a scientific basis for decision-making toward more sustainable reprocessing and valorization of sulfidic tailings

Tinjauan Hukum dan Kebijakan Pengelolaan Pulau-Pulau Kecil Terluar Indonesia (Studi Kasus Pulau Nipa)

Besides of large ocean and long coastline, Indonesia was also gifted resourceful islands, which were economically potential for our state development. Even the outer small islands were also have a strategic point as a base line from the Indonesian archipelago straight line in reconciling Indonesian water area, as the front liners of the state, and also support international passage. Nipa is one of the outer small islands that were recently being a public issue. Most of it was the anxiousness about the sinking of Nipa and coast reclamation by Singapore. Both of them concerned to be the causes of a significantly water area diminishing as the base line measurement changes between bordered states. That anxiousness was reasonable as concerning the lost of SipadanLigitan of which Indonesia and Malaysia disagreement. We need some juridical revision for the principal of outer small islands. Afterward, some management policy aspect is complementary required. This research was using a case study method compiled with formally juridical method. Primary and secondary data were analyzed with a qualitative analysis. This issue has three juridical law anvil of Indonesian ownership for Nipa Island, the Intemational Law, Bilateral Agreements, and National Law. From a juridical study, it is notorious that stronger law anvils compared with Sipadan and Ligitan supported Nipa and the other islands. Otherwise, the policy aspect contents about the issues and management strategies conducted by the government, which is mandatory, associated by MMAF, Ministry of Foreign Affairs and Ministry of Defends. The matrix policy described that the MMAF mostly participated than the others. Although it has strong law anvils for Nipa issues, Indonesia is forced to be concern about patches, which can be utilized by Singapore, as example for accomplishments of the baseline agreement and their activity construct in that island

Analisis Sumberdaya Ikan Cakalang (Katsuwonus Pelamis) Di Perairan Kabupaten Pohuwato, Provinsi Gorontalo (Resource Analysis of Skipjack (Katsuwonus Pelamis) in Pohuwato, Gorontalo Province)

Skipjack (Katsuwonus pelamis) is the one commodity that the waters of the Gulf of Tomini which potential and high economic value, and the fishermen used with various types of fishing technology. The aims of this study was to see whether the fish catches of skipjack influenced by extrinsic factors such as zones, depth, and season and knowing revenue per fishing effort. This study used primary data, especially on fish resources obtained through direct observation of research and interviews with actors fishery (fishing/crew, ship owners, collectors, officers TPI and other stakeholders), and the option to use a list of questions/questionnaire structured according to the research objectives. Secondary data were collected through the reporting of fisheries statistics include statistical data of domestic fisheries (RTP), statistics fleets and fishing gear, production data from the Department of Fisheries and Marine Gorontalo Province, Department of Fisheries and Marine Pohuwato, the Central Bureau of Statistics of Gorontalo Province Development Planning Agency Regional and Tomini Bay Sustainable Coastal Livelihoods and Management (SUSCLAM). In addition, a variety of literature supporting this research e.g. scientific publications, local publications and other documents. Data analysis was performed using resources through the stock abundance index data recording catches and the number of trips/boat/gear in the time series, to determine the allocation of fishing effort on the abundance of fish. Next will be the calculation of the catch per effort (CPUE, Catch per Unit of Effort). Analysis of the allocation of fishing effort done using monthly seasonal index (%), and forecasts an economic advantage by analysis Revenue per Unit Effort (RPUEj). The results of the study explained that the test results obtained by a factor wald gear types, depths and seasons significant effect on catches of tuna with a p-value <5%. The zone does not affect the catches of skipjack. Based on the Monthly Seasonal Index (Ij) that Ij the August high of 69, 05% then followed in July by 65, 94%. The results of the analysis Revenue per Unit Effort (RPUEj), the value of the highest RPUE for flying fish and tuna occur on in October of IDR 102,325,862
