6.1 Introduction

An IGCC facility can offer advantages over existing pulverised coal (PC) technologies with respect to most environmental impacts. In addition to the reduced air emissions, IGCC plants typically consume significantly less water in operation than PC plants and (depending upon coal properties) produce less solid waste, with the waste (slag) being more benign than the waste produced by PC plants.

The currently available carbon management technologies for IGCC facilities are more cost effective than similar technologies for removing CO2 from PC plant flue gases.

Environmental controls will be required to meet emission limits set by the regulators in the Development Approval.
