I want to dispose off,as safely as possible, Heavy fuel Oil Sludge/Waste from a power plant next to poor homes

Question

This is a poor community I visited in the THird World and I want to offer a cheap solution for the sake of the people living there.

Answer 1

If this is a fly ash sludge i have heard that it can be added to concrete. The link below is informative
............In addition to economic and ecological benefits, the use of fly ash in concrete improves its workability, reduces segregation, bleeding, heat evolution and permeability, inhibits alkali-aggregate reaction, and enhances sulfate resistance. Even though the use of fly ash in concrete has increased in the last 20 years, less than 20% of the fly ash collected was used in the cement and concrete industries (Helmuth 1987).........

Without know what the exact nature of the waste is it is hard to recommend what you can do with it.

Answer 2

There some recovery techniques that work well .
One is with a steam boiler to heat a huge vat of water and as the oil heats up u can skim it off .
One of the older technique is to set it on fire and burn it,some of the environmentalist wound disagree but they think that it increases the CO2 level but our plants like CO2 and they convert it to oxygeon.
