for the last few years we have amassed 4000-6000 litres of waste oil per
year.
This is mainly used engine oil from industrial diesels but also a small
percentage of gear oils, hydraulic oils and diesel fuel.
This is stored in ibc's and taken away when all four are filled.
An increasingly costly process.

Does anyone know of an economical way of either using this waste for heating
purposes or a more economical method of disposal.


You can make a burner for this stuff, but the real problem is getting
rid of dissolved pollutants.

The will clog filters and burner nozzles, and push some pretty illicit
compounds into the atmosphere.


Thanks,
