Future Role of Anaerobic Digestion in Municipal Waste Management

Municipal waste management and Waste-to-Energy (WtE) potentials in New Zealand are discussed. The existing main waste management strategy of New Zealand is to reduce, reuse and recycle waste. Most of the remaining waste is currently disposed of in landfills. WtE options were explored in this study as a more sustainable waste treatment alternative in the country, while making use of the annual 30.8 petajoule of available waste energy in New Zealand. Four WtE technology options were discussed and compared, namely incineration, anaerobic digestion, gasification and pyrolysis. The aspects in comparison were air pollution, cost, side products, capacity, commercial maturity, energy efficiency and type of waste treated. Special emphasis was given to environment-friendliness and cost. From the comparison, it was found that anaerobic digestion seems to be the most attractive solution for the country as it is environment-friendly, economical and the concept is consistent with New Zealand’s existing waste management strategy. The major limitations of anaerobic digestion are its low energy production efficiency and its limited waste treatment capacity. Hence, an effective national waste reduction and recycling strategy is crucial for the success of this waste management option.

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.
