present in <strong>the</strong> waste and that <strong>the</strong> <strong>temperature</strong> of <strong>the</strong> injected liquid is <strong>the</strong> ambient <strong>temperature</strong>.<br />

According to <strong>the</strong> results, <strong>the</strong>re was a significant gap between <strong>the</strong> expected and <strong>the</strong> actual wetted<br />

volume. The waste volume actually wetted was < 1% to 9% of <strong>the</strong> total waste volume expected<br />

to be wetted. Also studied was <strong>the</strong> effect of ambient <strong>temperature</strong> on <strong>the</strong> waste <strong>temperature</strong>. It<br />

was observed that <strong>the</strong> ambient <strong>temperature</strong> has no effect on <strong>the</strong> global <strong>temperature</strong> <strong>inside</strong> a<br />

bioreactor <strong>landfill</strong> even at a shallow depth of 4.6 m. While analyzing <strong>the</strong> trend of waste<br />

<strong>temperature</strong> <strong>inside</strong> <strong>the</strong> <strong>landfill</strong>, liquid injection was found to lead to an increase in <strong>temperature</strong>.<br />
