Waste Management Policy

Municipal solid waste management is an environmental issue that has received considerable attention from researchers and environmental managers for decades. Supporting the management programs entail policies and regulations related to municipal solid waste. In developed countries, the implementation of environmental policies plays an important role and has a substantial impact on the effectiveness of solid waste management. However, in many developing countries such as Vietnam, the situation and effectiveness of the policy implementation have not been studied extensively. This investigation is conducted to ascertain the situation, limitations, and challenges in implementing solid waste management policy in Vietnam. Then, solutions for the problems and improvements for implementation efficiency are presented. This work used online questionnaires to survey environmental managers in different localities and applied qualitative research method to analyze data. The results show that not all national policies on solid waste management are implemented in all localities. Waste separation is also the foremost concern in municipal waste management in most localities of Vietnam. Most of the localities claimed that the unrealistic nature and difficult implementation of the policies and the lack of needed resources are the main limitations and challenges in Vietnam. Survey results also revealed that different localities in Vietnam have different solutions to increase policy implementation efficiency. Besides, the study also found similarities in the implementation of policies in solid waste management between Vietnam and some other countries and also gathered some valuable lessons for the improvement strategy. Finally, the implementation of an effective domestic solid waste management policy is an important platform for improving environmental quality and ensuring the sustainable development of the nation and mankind.

High Alumina Content

Coal gangue is a kind of solid waste which is discharged from coal mining and coal washing. Dumped gangues do not only take a large land occupation but also pollute air and water. Treatment and utilizing of coal gangues has become the major issue for the coal industry to resolve. As major experimental material in this study, the coal gangue from Dawukou, Shizuishan, Ningxia province, China had been analyzed to have high-alumina content, and it could been used as alumina constituent for the preparation of sulphoaluminate cement. In this paper, alite-sulphoaluminate cements were prepared at 1330°C using coal gangue, limestone and gypsum as major main materials, fluorite and barite as minor materials. The result shows that major clinker minerals of the cement are sulphoaluminate, alite and belite, while major hydrate is ettringite, compressive strength of the cement is 48.9MPa after 7d. These experiments provide a new method of coal gangue comprehensive utilization.

<p class="abstract"><strong>Background:</strong> The present study has been carried out to investigate the physicochemical and micronutrients properties of vermicompost generated from the major municipal biodegradable solid waste (fruits and vegetables) by using two common species of earthworm i.e., <em>Eisenia foetida and Eudrilus eugenia</em> in National Thermal Power Corporation (NTPC), Barh, Bihar (India).</p><p class="abstract"><strong>Methods:</strong> Compost pH was measured in distilled water (free of CO<sub>2</sub>) using 10 g of compost sample and 25 ml distilled water (ratio 1:2.5). The suspension was agitated for 3-5 min and placed for half an hour before measuring the pH value with a glass. Organic carbon was measured by Walkey and Black method, total N by Kajeldahl method, P<sub>2</sub>O<sub>5</sub> was determined by means of colorimetric method and K<sub>2</sub>O, Cu, Zn, Mo, Mn, Fe and B were determined by the means of Hi Media Kit.  </p><p class="abstract"><strong>Results:</strong> Among the micronutrients in harvested vermicompost, increase in Zn, Cu and B contents and slight decrease in Mo content were observed when compared to standards given in soil health card of the State Government of Bihar. Mn and Fe were found to be critical in the harvested vermicompost samples. The level of boron (B) in vermicompost was found much higher than the required availability in the soil.</p><p><strong>Conclusions:</strong> On the basis of overall physicochemical as well as micronutrients properties of the vermicompost prepared in NTPC is of better quality in compared to the other vermicompost. </p>
