In Scenario 1, all the waste generated is assumed to be taken to landfill, that is land filling is the only disposal
method for the waste, except for some few waste from plastic bottles and papers which was picked by scavengers
before reaching the landfills. While in the second scenario, the syngas is generated from the waste based on the
gasification conversion technology. The syngas is then used in electricity generation and this will reduce the
environmental effect drastically because the remaining materials to be land filled are mostly inert materials with a
reduced volume, too.
