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. The paper also proposes some solutions to promote symbiotic activities in the industry.

Opis:
Ganoderma sinense, a well-known medicinal macrofungus of Basidiomycetes, is widely used in traditional medicine for promoting health and longevity in East Asia. The fruiting bodies of G. sinense contain polysaccharides, ergosterol, and coumarin, which have antitumor, antioxidant, and anticytopenia activities. Mushroom cultivation requires suitable conditions for the formation of fruiting bodies and yield. However, little is known about the optimal culture conditions for mycelial growth and cultivation of G. sinense. In this study, the successful cultivation of a G. sinense strain collected from the wild was reported. The optimal culture conditions were identified by examining one factor at a time. The results of this study revealed that the nutritional requirements for the optimal mycelial growth of G. sinense were fructose (15 g/l) as the carbon source and yeast extract (1 g/l) as the nitrogen source. The optimal pH and temperature for G. sinense were 7 and 25–30EC, respectively. The mycelia grew fastest in treatment II (69% rice grains + 30% sawdust + 1% calcium carbonate). G. sinense produced fruiting bodies under all tested conditions and showed the highest biological efficiency (2.95%) in treatment B (96% sawdust, 1% wheat bran, 1% lime). In summary, under optimal culture conditions, G. sinense strain GA21 showed satisfactory yield and a high potential for commercial cultivation.

Opis:
The circular economy is the economic model that has been applied for a long time in the world. This model is applied at all three levels: micro (enterprise-level), intermediate (industry level, industrial zone level), and macro-level (local level, regional level, or national level). Vietnamese Coal Mining Industry has been having important contributions to the socio-economic development of Vietnam. However, this industry also causes lots of issues about environmental pollution. In the context of resource depletion, environmental pollution and the cost of exploiting and processing increases with the deep exploiting process; the tastes of utilizing resources, minimizing environmental pollution, and creating more value-added for this industry are inevitable requirements. Because of the tasks, applying the circular economy model into this industry (both intermediate and micro-level) is the urgent solution for the sustainable development of the Vietnamese Coal Mining Industry. The paper uses a combination of research methods such as theoretical research, case study research, statistical data analysis, etc., to propose the circular economy model for the Vietnamese Coal Mining Industry and some solutions to deploy this model into the industry's operations towards sustainable development.
