Sustainable development is a crucial issue that has been particularly emphasized by the Party and the Government of Vietnam, especially in areas with a large population of ethnic minorities. The Southern Central Highlands is currently home to nearly 50 ethnic groups, among which local ethnic minorities such as the Ê Đê, K’ho, and M’nông are striving to develop their economy, culture, and society sustainably. However, this development process faces numerous challenges from both objective and subjective factors, including natural conditions, government development policies, ethnic psychology, and religious factors. At present, Catholicism and Protestantism are the two main religions within the ethnic minority communities of the Southern Central Highlands. Introduced to the region from the late 19th to early 20th century, these two religions flourished in the second half of the 20th century and have become major elements in the spiritual lives of the communities. Religion has had and continues to have significant impacts on the economic, cultural, and social development of local ethnic minorities, contributing positively to the process of sustainable development. This article uses data collected from the community through participant observation, in-depth interviews, and survey questionnaires to analyze the impact of religion on the economic, cultural, environmental, and social aspects of local ethnic minorities in the South Central Highlands in the context of sustainable development.

Vietnam's economy is operated to serve more than ninety million people so this is a very vivid picture. The large population brings many advantages to the food production sector in general and the production of fresh noodles in particular. Fresh vermicelli is the raw material for processing many dishes of the Vietnamese people for a long time, that's why there are many Vietnamese dishes with indispensable ingredients, which as Noodles in the national culinary books. Vietnam. The production of fresh vermicelli with the main ingredient is fermented and shaped rice with simple steps, but hidden inside there are environmental issues that need to be considered. The production and business associated with environmental protection are the responsibility of most enterprises and production facilities in Vietnam. The fresh noodle food production industry is no exception. Instead of learning about the aspects that affect the environment in the traditional way of collecting information, analyzing, and evaluating the current situation, this time the research team looked at understanding the causes of environmental pollution in terms of consumption. ISO 14001 international standard. ISO 14001 Environmental Management System is an international standard that helps businesses and establishments identify the important role of the environment as well as the risks brought by the environment, thereby realizing the environment as an activity of the Organization. In this standard, the commitment to prevent environmental pollution is a mandatory condition, so determining the environmental aspects to overcome the impacts is a key element of the standard. If a business achieves ISO 14001 Certification, it will have a very good effect in promoting the corporate image of being responsible for the environment and the community.

Selecting wastewater treatment technology is not an easy matter. In this study, TOPSIS and AHP methods are used to support decision-making in choosing a wastewater treatment alternative for Poong In Vina factory. A total of 9 criteria belonging to 3 groups of economic, social - technical and environmental issues were used to select an alternative. The results of TOPSIS and AHP analysis showed that aerobic biotechnology integrated with membrane bioreactor technology is the optimal solution. The outcomes of this study will help the company in choosing the best option among these technologies. Furthermore, it will provide an insight for relevant stakeholders such as engineers, manufacturers and other ogranizations for making decisions.

Recognized as a smart city, Binh Duong's smart city development strategy also includes the development of automated agriculture, typically large-scale livestock farming. A sustainable urban development will not be able to ignore the factor of providing food for urban and regional people. Phu Giao district - Binh Duong province is one of the leading districts in livestock farming, especially concentrated pig farming. The agricultural industry, pigs breeding, is one of the strengths of the district, besides the cultivation of short and long-term industrial crops such as rubber, cashew, Ho Tieu... Livestock is a very old profession of the Vietnamese people in Phu Giao district as well as in Binh Duong province. The contribution of livestock production to the socio-economic face of the district cannot be denied. However, animal husbandry activities, besides the economic values, also cause some consequences to the natural environment such as soil and water pollution, noise, odors in the air, etc. Hence, we decided to do the research of "Application of ISO 14001:2015 international standards in determination of environmental aspects at market hog farm with semiautomatic technology farm size 12,000 pigs per year in Phu Giao district, Binh Duong province" (TCVN ISO, 2015). This is a large-scale pig farm with modern semi-automatic technology equipment. We expect to find out environmental issues in the most detailed and specific way so that the owner can overcome the above environmental problems, rest assured to raise livestock and develop more expansion later. We conducted a review of the areas on the farm, evaluated the activities in each area, from which we found out the environmental problems through the material flow diagram (Phạm Thị Hồng Cẩm, 2020). Next, through the multi-criteria method (Phạm Thị Hồng Cẩm, 2020) we calculated the score and found the most significant environmental aspects (most environmental risk). The research results will be a general picture to provide farm owners with an intuitive and easy-to-understand view for suitable solutions. Developing farm economy along with environmental protection towards sustainable development of livestock agriculture.

Environmental issues such as the wastewater have influenced each aspect of our lives. For human and environmental health protection, it is necessary to remove excess zinc in industrial wastewaters before discharging them to environment. Modified diatomite displayed larger surface area and pore volumes in comparison with untreated natural diatomite, which favored heavy metals sorption behavior. In this study, the removal of Zn(II) ions from aqueous solution was studied using Fe/Mn modified diatomite sample at different adsorption parameters such as contact initial metal ions concentration, dosage of Fe/Mn-Diatomite and ionic strength Na2CO3 on ionic Zn2+ adsorption capacity of diatomite modified. The residual zinc concentration in the solution was determined using flame atomic absorption spectroscopy. The results showed that: the gravitational increase increases with increasing time and then becomes almost stable, with 120 minutes timeliness; absorption increases when Fe/Mn-Ditomite is increased, absorption reaches 89.48% at a dose of 1.5 g/l; additional different concentrations Na2CO3 ranged from 0 ppm to 80 ppm the results showed that performance treatment Zn2+ of correspond 94,85%. This study could lay an essential foundation to develop modified diatomite for heavy metal removal from wastewater.
