To date, no biodegradability studies by means of respirometry have ever been carried out for the evaluation of pyrolysis liquids. This preliminary report is an initial attempt to do so. The study was carried out in close collaboration between experts in the field of pyrolysis (RTI) and respirometry specialists (Conestoga-Rovers), both of Waterloo, Ontario. The study found that:
- The technique of respirometry is very suitable for preliminary assessment of the degradation behaviour of bio-oils in natural environments.
- Pyrolysis oils biodegrade aerobically at a substantially higher rate than hydrocarbon fuels.
- pH neutralisation of the bio-oil enhances biodegradability. Such enhanced biodegradability in an aquatic environment was a surprising finding in the light of recent rather negative reports by Ontario Hydro Technologies.
