Green ponds of raw waste, eighteen inches deep, blocked the roads between apartment houses where children played.
The ultimate aim is to invent a toilet technology that doesn't require sewers or water for flushing, and doesn't need to be emptied of raw waste.
The natural formation of desiccation-crack networks at the margins of waste lagoons induces rapid infiltration of raw waste to deep sections of the vadose zone, bypassing the sediment's most biogeochemically active parts, and jeopardizing groundwater quality.
Chemical oxygen demand (COD) of raw waste water samples.
The samples of raw waste water (stored at -32°C) were thawed; the treated waste water (stored at 4°C) was brought to room temperature.
The underlying results of raw waste water samples, given in Additional file 1: Figure af1, show high variations of antiepileptic drug concentrations over time.
That's a lot of raw waste material transformed into saleable, marketable consumer goods.
With 130 million litres of raw waste flowing into the Pacific every day, that leaves about 2,190 more days and some 200 trillion litres of poo until a new treatment plan is expected to be in place.
Leaching tests evidenced the reduction in the release of heavy metals from the tested mixtures compared to that of the raw waste indicating successful stabilization/solidification of such waste in the grout.
