Strengthening Indonesia's Nickel Downstream Industry through Green Energy-Based Smelter Technology

Indonesia holds the world's largest nickel reserves, estimated at 55 million tons in 2024, making it a key player in the global nickel industry. The government has enacted downstream policies, such as a ban on raw ore exports and mandated domestic processing through Ministerial Decree of Energy and Mineral Resources (ESDM) No. 17 of 2020, to maximize its potential. These policies have accelerated the development of green energy-based smelters, which aim to enhance value addition while reducing environmental impacts like carbon emissions and hazardous waste. This study explores the current conditions and future prospects of developing nickel smelters in Indonesia, focusing on the policies in place, their economic impacts, and the role of green technologies in supporting smelter development initiatives. It highlights the economic, environmental, and social benefits of green technologies in Indonesia's nickel downstream industry. Innovations such as nanotechnology, Chemical Mechanical Polishing (CMP), bioleaching, and High-Pressure Acid Leach (HPAL) show significant potential by reducing emissions, waste, and energy consumption. PT Vale Indonesia, a leading player in the industry, exemplifies this transformation through initiatives like fuel shifting, renewable energy utilization, electrification of equipment, and energy efficiency measures. Despite challenges like high costs, infrastructure limitations, and waste management issues, green smelters substantially contribute to job creation, competitiveness, and environmental preservation. Continued policy support and cross-sector collaboration are crucial. However, it's the investment in research that holds the key to overcoming these barriers and positioning Indonesia as a global leader in sustainable nickel productionIndonesia holds the world's largest nickel reserves, estimated at 55 million tons in 2024, making it a key player in the global nickel industry.

Characterization and Enzymatic Assay of Cellulase-Producing Probiotic Bacteria Isolated from Traditional Fermented Bamboo of Bangladesh

Fermented bamboo (also known as Ngwopo) is a traditional food item among the indigenous population living in the south-east of Bangladesh. Though fermented foods harbour a significant number of probiotics and enzyme-producing bacteria, there is a lack of research on isolating beneficial bacteria from native fermented food products in Bangladesh. Thus, considering the extensive utilisation of cellulase enzymes and probiotics, our study was conducted with the objective of isolating and characterizing native cellulase-producing bacteria from fermented bamboo and performing crude enzyme activity assay. The sample was collected from Khagrachari hill tracts district of Bangladesh. Three isolated bacteria, namely FB-1, FB-2, and FB-3, screened based on the carboxymethyl cellulose medium, were tested for biochemical and probiotic properties, and the best isolate was genetically identified by molecular characterization through 16S rRNA gene sequencing and evolutionary analysis. All three gram-positive isolates were observed to be positive for starch hydrolysis and fermentation of sucrose, suggesting their ability to breakdown carbohydrates while testing negative for gelatinase, indole, and H2S test. The isolates demonstrated moderate bile salt and pH tolerance and low to medium autoaggregation. FB-2 had 75% susceptibility to the tested antibiotics, while other isolates were susceptible to 50% antibiotics. All of the bacteria were non-pathogenic, showing γ-haemolysis. FB-2 strain showed an enzyme production capacity of 1.56 units/ml. The best performing isolate was identified as Bacillus cereus. Therefore, the study discovered a native bacteria potentially suitable as probiotic and as a source of cellulase for industrial processes, highlighting the enriched indigenous cuisines of Bangladesh
