Case Study // Waste Management in Danang, Vietnam

By Martin Schaub and Jérémie Bertrand. This case study analyses the feasibility of viable solutions for an environmentally friendly and future-proof disposal of approximately 1,000 tonnes per day of municipal waste at Da Nang, the fourth largest city in Vietnam and largest city in Central Vietnam. The authors show that a technology apt to meet the specific waste composition of the reagion could replace the energy-inefficient and uneconomical incineration treatment with a Nexus approach-based treatment that could pay off, save energy and water.

For the two landfill sites near Da Nang, Khanh Son and Hoa Nhon, this study develops a waste management concept with the aim of incorporating advanced mechanical biological waste treatment technologies in order to improve the economic and ecological situation of waste disposal. The concepts are based on data collected at the two sites and these data were combined with international, regional as well as site- specific information and political guidelines of decision-makers (stakeholders). Subsequently the required technical processes are adapted to the site conditions. Finally the new plants are dimensioned and budgeted in this study. The case study describes two concepts for a Sustainable Waste Management System for the two locations Khanh So and Hoa Nhon.

The study has been undertaken as part of the project "Integrated Resource Management in Asian Cities: The Urban NEXUS". Similar studies have been published for cities in IndiaIndonesia and the Philippines.

Agua, Producción de Alimentos y Energía // La Experiencia del Nexo en Chile

Por Humberto Peña. El presente estudio analiza este Nexo en el caso de Chile. Con ese propósito, se revisa la evolución de las políticas públicas y los marcos institucionales relacionados con la gestión del agua, y el desarrollo del riego y de la energía eléctrica. En el análisis se distingue entre: un período inicial; otro donde el Estado fue el motor del desarrollo; un tercero con un predominio del mercado; y, finalmente, uno donde se busca un nuevo equilibrio entre el interés público y los...

Efficiency Type Index // Analysis of the current World Biofuel Production under a Water–Food–Energy Nexus Perspective

By Emanuele Moioli, Federico Salvati, Marco Chiesa, Rosa T. Siecha, Flavio Manenti, Francesco Laio, Maria Cristina Rulli. This paper assesses the sustainability of bioenergy production under a nexus perspective through a new efficiency type index. The index describes 1st generation biofuel production under the perspective of the implied consumption of natural resources. The direct application of the nexus index entails an indication of the possible improvements needed to move production towards...
