Urban Eco-Development & MetabolismUrban Eco Development & Metabolism“System-oriented study of the physical, chemical, and biological interactions and interrelationships both within urban systems and between urbanand natural ecological systems.”•Urban metabolism aims at finding strategies and methods to g gminimize the negative impacts of urban systems on surrounding systems.•Urban metabolism as a framework tries to give guidance towards the transformation of urban systems.

UED O ti li tiUED Operationalization “A community of residential, commercial / service
performance through collaboration in managing
businesses seeking enhanced environmental economic, and social
performance through collaboration in managing environment and resource issues including
information, energy, water, materials, infrastructure and natural habitat By workinginfrastructure, and natural habitat. By working
together, the community seeks a collective benefit that is greater than the sum of the
individual benefits each entity would realize if itindividual benefits each entity would realize if it optimized its individual performance only.”

Incineration of Scampi Shellsp
• Scampi contains flesh that is cannot be put in landfill legally (particularly the claws and head part). That is why producers plan to transport them in France and made it as a soup but the environmental and economical cost of it would be high. The area is not yet capable of composting in a high temperature.

The Importance of the Informal pWaste Sector• Although their methods are primitive, the
informal waste sector in developing countries cannot simply be eliminatedcountries cannot simply be eliminated
• A theoretical study on the incorporation of the informal waste sector in e-wastethe informal waste sector in e waste material recovery showed that eliminating the informal waste sector may not necessarily be beneficial for the environment and for the human health (T & Li 2011)(Tee & Li, 2011)
