Abstract
An approach to the design of sustainable systems
for meeting the basic urban services, as well as the food and energy requirements,
of communities of different sizes is discussed, using integrated systems
as a common design feature. The presentation begins with a definition
of a sustainable system and includes discussions on integrated solid waste
management and defining the system boundary. Some components of the
overall system (solid waste, wastewater treatment, food production, energy
production, and others) are described, along with the characteristics that
are common among two or more of the components, thus enabling their meshing
into integrated systems.
Examples of integrated
and sustainable systems are presented in the form of material and energy
balances, including one integrated system composed of solid waste management,
wastewater treatment, energy production, and food production facilities.
In this example, nutrient and energy requirements are used as the common
bases of design and integration.
