Thermal Depolymerisation (TDP) of Waste

I’m not very knowledgeable in chemistry. Yet the thermal depolymerisation of waste video »400$ Billion Dollar Secret« drew my attention. It looks like advertorial to me. But nevertheless we should consider processing waste and sludge in this way than by burning or burying it or other ways currently used, if the presented data on TDP is correct. The presented process shows processing of waste back into gasoline, fuel and other materials. Yet despite the relief to know that something more thorough and efficient then common practices is possible it was awkward to watch how an assembly line of turkey that duration limit has exceeded entering the thermal depolymerisation. We can easily imagine other living beings in such situation.

For decades I live nearby a city waste dump. Now it is closed, grass over its surface, and it produces fuel for the nearby urban setting. Before using it as a source of fuel it started burning repeatedly. Fire workers had to put out the fire quite often. Before it became a dump the huge hole was used as a gravel pit and a local swimming option; it was surrounded by fields, small forests and meadows. After the local authorities decided to use it to dump the waste from one major and some smaller cities, all wells downstream were polluted, people and animals stared getting sick, the vegetables were of dubious quality and the stank spread all around. After it was closed the local authorities couldn’t find another place for dumping city waste, so they packaged it in bales and stored it nearby highway and cemetery, and the same thing happened again except fires – people got sick, the stank was all around, it polluted the underground water.

So after reading about this thermal depolymerisation option I asked myself why don’t the people in charge use this option in combination with packing waste in bales. Well, maybe my idea is just too outlandish.
