WORKSHOP 1

Waste as a Resource

Highly populated cities generate enormous quantities of waste.
After separation of hazardous components most of the waste
can be re-circulated, nutrients and other components can be
withdrawn from it, and heat and bio-gas can be produced.
The treated wastewater itself can be used for irrigation,
groundwater recharge, other beneficial purposes and to maintain
ecological flows. Sewage sludge, which contains organic matter, nutrients, microelements and valuable humic substances
necessary for agriculture, also has great potential for reuse if
properly treated. The collection and treatment of waste should
not only be viewed as a necessary expense to promote health
and safety. Instead, it presents great opportunity as a largely
untapped and valuable source of organic matter.

This workshop will focus on ways to develop systems that
can best utilise resources hidden in treated wastewater,
sludge and solid waste. How can this be accomplished
without posing risks to health, safety and the environment? With increasing pressure on conventional energy sources,
it will also be important to provide relevant examples on
the best ways and practices to use these resources for
energy production.
