Opis:
Industrial symbiosis associated with the eco-industrial parks is the cooperative activities between businesses to optimize using of inputs and outputs such as raw materials, energy, water, waste materials, etc. in the orperation of businesses. In the industrial symbiosis model, the overall benefits of the symbiosis activities are more than the ones when working individually. Applying the model could help to reduce the demand of raw materials and increase the waste that be treated – an important part of the circular economy model. The coal mining industry includes many different stages from exploration, exploitation, processing, and trading. Each stage could be performed by different businesses which could corporate with each other. Besides the contributions to the socio-economic development, the industry also emits lots of waste into the environment to cause environmental pollution that needs to be treated. The paper summarizes the theoretical basis of the industrial symbiosis, the circular economy and clarifies the relationship between the industrial symbiosis, the circular economy and the sustainable development goals. From analyzing some typical situations of industrial symbiosis activities in Vietnamese coal mining industry; analyzing some characteristics and potential application of industrial symbiosis in the industry, the paper proposes the model of industrial symbiosis for Vietnamese coal mining industry.

Opis:
Vietnam has a potential reserve of placer titanium of around 650 Mt. The reserve lays in sandy beaches of the country from Thanh Hoa to Binh Thuan province. Placer titanium mines in Vietnam are different in geological condition, the scale of production, mining method, and environmental protection solutions, etc. Some of them are operating with inappropriate mining technology; therefore, have caused environmental issues and ineffective operation. Consequently, it is essential to have criteria for selecting appropriate mining technology to approach the sustainable development for the mines. Based on categories of geology, the scale of production, mining characteristics, requirements of safety, land reclamation and environmental protection, and mining effect, authors defined the criteria and method for selecting adequate mining technology for the placer titanium mines in Vietnam which aim for better safe, effective and sustainable. The categories to select the appropriate technology for coastal titanium placers in Vietnam including 1- feasible mining scheme, 2- mining procedure, 3- requirement volume of water, 4- slope stability, 5- environmental rehabilitation and reclamation, and 6- economic effect. The result of the application for Nam Suoi Nhum placer titanium mine in Bình Thuan province shows that the most appropriate scheme of this mine is the mining technology of using hydraulic jets, pumping and hauling by pumping mud, processing by spiral screws, and discharging by mud pumping.
Wietnam ma potencjalne rezerwy okruchowego tytanu w wysokości około 650 Mt. Rezerwat leży na piaszczystych plażach kraju od Thanh Hoa do prowincji Binh Thuan. Kopalnie okruchowego tytanu w Wietnamie różnią się stanem geologicznym, skalą produkcji, sposobem wydobycia, rozwiązaniami w zakresie ochrony środowiska itp. Niektóre z nich działają na niewłaściwej technologii wydobywczej, w związku z czym spowodowały problemy środowiskowe i nieefektywną eksploatację. W związku z tym niezbędne jest posiadanie kryteriów doboru odpowiedniej technologii wydobywczej do podejścia do zrównoważonego rozwoju. W oparciu o kategorie geologiczne, skalę produkcji, charakterystykę górniczą, wymagania bezpieczeństwa, rekultywacji gruntów i ochrony środowiska oraz efektu górniczego, autorzy określili kryteria i sposób doboru odpowiedniej technologii wydobycia dla stacjonujących kopalni tytanu w Wietnamie, które mają na celu zwiększenie bezpieczeństwa , efektywne i trwałe. Te kategorie obejmują 1- wykonalny schemat wydobycia, 2- procedurę wydobycia, 3- wymaganą ilość wody, 4- stateczność zboczy, 5-rekultywację środowiska oraz 6-efekt ekonomiczny. Wynik zastosowania dla kopalni okruchowego tytanu Nam Suoi Nhum w prowincji Bình Thuan pokazuje, że najbardziej odpowiednim schematem tej kopalni jest technologia wydobywcza wykorzystująca strumienie hydrauliczne, pompowanie i ciągnięcie przez pompowanie szlamu, przetwarzanie za pomocą śrub spiralnych i odprowadzanie przez pompowanie błota.

Opis:
Coal mining is one of the key mining industries in Vietnam. Coal is also an important fuel for many other industries. Currently, coal mining is mainly concentrated in Quang Ninh coal basin, the proportion of open-pit coal mining and underground mining is quite similar. However, according to Decision 403/QD-Ttg on approving the adjustment of the Vietnam coal industry development plan up to 2020, considering the prospects by 2030, the mining output will be from 51 to 54 million tons by year 2025 and from 55 to 57 million tons by 2030. In which, the proportion of underground coal mining will increase gradually compared with that of open-cast mining, specifically, by 2030, the proportion of the later compared to that of the former will be only 11%. According to this plan, open-pit coal mines have been shifting to underground mining technology, due to the increasingly deep conditions of coal seams. The following article will analyze the current status of coal mining in Vietnam and some highlights of the coal industry development plan to 2030, in order to provide a general picture of Vietnam’s coal industry in the future.

Opis:
This research evaluated rice growth and yield as well as Zn accumulation in both soil and grain under saline water irrigation conditions. The experiment consisted of a series of pots containing rice plants and paddy soil, with the application of irrigation treatments of five different salinity levels (1.5, 2, 3, 4, and 5‰ with a drip irrigation system). The results show that the salinity accumulation levels in soil can increase by up to 2.8‰ following the application of 5‰ salinity irrigation water during the development stages. Besides, this study also aimed to evaluate the influences of saline water irrigation on the observed rice yields, plant height, leaf length, and leaf width. In the results, irrigation with 3‰ saline water reduced potential rice yield by 58.6% and the length of rice leaves by one-third. Higher salinity of 4‰ in the irrigation water produced only 24% of average potential productivity, and 5‰ water salinity resulted in no yield. Furthermore, salt stress limited the mobile Zn content in paddy soil, reducing the Zn accumulation in grains by between 36.27% and 83.21%. Thus, the study shows that controlling salinity in irrigation water management is essential for controlling the yield and nutrient Zn content in rice grains.

Under the influence of the 4th industrial revolution and the impact of the Covid-19 pandemic, digital transformation is rapidly taking place in all aspects of society. For businesses, digital transformation is an essential and objective trend for their sustainability and development. The purpose of digital transformation for businesses is to enhance operational efficiency through factors such as accelerating market speed, gaining competitive advantage, driving revenue growth, increasing labor productivity, and expanding customer attraction and retention. Numerous studies have indicated that the process of digital transformation in businesses is influenced by leadership and digital transformation strategies, and digital transformation has an impact on business performance. This study aims to identify the relationship between digital leadership and the operational efficiency of coal mining companies in Vietnam, with the mediating role of digital transformation strategies. Additionally, the study examines the moderating role of digital skills on the relationship between digital transformation strategies and the operational efficiency of the organizations. The research surveyed 111 employees and workers currently working in coal mining companies in Vietnam. Through analysis and hypothesis testing, the results showed that digital leadership does not have a direct impact on coal companies’ operational efficiency. However, it indirectly affects business performance through the mediating role of digital transformation strategies. The study's findings also revealed that the digital skills of employees play a moderating role in enhancing the relationship between digital transformation strategies and the operational efficiency of the organization.

Cadmium (Cd) is toxic for humans, but its effects on the yield and quality of rice under contaminated irrigation conditions remain uncertain. In this study, paddy soils in the Red River Delta (Vietnam) were selected for experiments with the purpose of understanding the effects of Cd contaminated irrigation water on growth, yields, and grain Cd accumulation. In addition, biochar was produced from rice husk (BRH) and rice straw for preventing Cd infiltration into rice was also studied in this experiment. A field experiment was established with applicated BRH and straw into polluted paddy soil, as a result the Cd content in grains reduced significantly. The Cd contaminated soil was added to the BRH and rice straw (RS) with six ratios, including: (1) RS 2.5%, (2) BRH 2.5%, (3) RS-BRH: 1.25–1.25%, (4) RS 5.0%, (5) BRH 5.0%, (6) RS-BRH: 2.5–2.5%, (w:w). Besides, three content levels 0.01–0.05–0.5 mg/L of Cd in irrigation water were applied throughout crop season. The results showed that the Cd accumulation in rice was in the following order: roots > stems > seeds. With 3 contaminated irrigation levels which were applied, the Cd concentrations of 0.05 mg/L and 0.5 mg/L affected plant height and yield. However, the Cd content in grains under contaminated soil condition can be controlled from 82.47–83.94% by applying a BRH ratio from 2.5–5% (w:w).
