Comparison of resource efficiency of systems for management of toilet waste and organic household waste
(2003) 2nd International Symposium on Ecological Sanitation p.759-766- Abstract
- Using a system analysis approach compares different systems for handling and treatment of
toilet waste and organic household waste. Design issues considered are source separation of
urine, use of vacuum toilets and advanced nutrient recovery processes such as Reverse Osmosis
(RO). All of the studied systems have low emissions of eutrophy ing compounds. Other environmental
effects are mainly related to the amount of exergy used at each system. Source
separating of urine is favourable if only a moderate (50 - 70 %) recycling potential for nutrients
such as N and K is required. However, if hi gher recycling potential is required systems using
nutrient recovery processes such as... (More) - Using a system analysis approach compares different systems for handling and treatment of

nutrient recovery processes such as RO/evaporator are probably to prefer. For vacuum sy stems,
the maximum amounts of flush water must be below 10 lit/p,d to make them reasonable
efficient in terms of exergy consumption. The low-flush systems are less sensitive to the use of
flush water in terms of exergy consumption. (Less)
