Correction (March 19, 2007)

In the February 19, 2007 EcoWeek report on the Air & Waste Management Association Conference, the following corrections should be noted in the section on Plasco Energy Group's project in Ottawa.

The reference to the kwh of electricity per megajoule (MJ) of energy should have been stated as "82 kWh can be generated per 1000 MJ of energy processed," rather than 110 kW per MJ of energy.

The 85 tpd of waste is correct, but the 16,500 MJ of energy is per tonne of waste processed. The Ottawa project is expected to generate 1.15 megawatt-hours (MWh) net per tonne of waste, enough to supply a typical household for 45 days. Future projects, which will operate in combined-cycle mode are expected to generate 1.4 MW, enough to power a home for two months.

The tipping fees have been set at $40/tonne for the Ottawa project only. Other projects may get $60 to $75/tonne. The sentence used in the text seems to suggest that this particular Plasco operation (the Ottawa project) will get $60 - $75/tonne which is incorrect.

EcoWeek regrets the errors.
