Convert yards of dirt to cubic feet by multiplying the number of yards by 27 (one yard equals 27 cubic feet).onvert cubic feet to pounds by multiplying by the bulk density of topsoil, and then converting from cubic feet to tons. This is 83 pounds per cubic foot by 108 cubic feet, for a mass of 8,964 pounds.
Thermal hydrolysis is a two-stage process combining high-pressure boiling of waste or sludge followed by a rapid decompression.This combined action sterilizes the sludge and makes it more biodegradable, which improves digestion performance.he city of Oslo, Norway installed a system for converting domestic food waste to fuel in 2012. A thermal hydrolysis system produces biogas from the food waste, which provides fuel for the city bus system and is also used for agricultural fertilizer.
The process is called alkaline hydrolysis and was developed in this country 16 years ago to get rid of animal carcasses. It uses lye, 300-degree heat and 60 pounds of pressure per square inch to destroy bodies in big stainless-steel cylinders that are similar to pressure cookers.Since they first walked the planet, humans have either buried or burned their dead. Now a new option is generating interest â dissolving bodies in lye and flushing the brownish, syrupy residue down the drain.
