Dozens of people in the Ringsend area took to social media over the past two days to raise concern that white plumes were billowing out of the Poolbeg Incinerator. The plant took its first loads of rubbish from trucks last week and was due to start burning waste at the weekend.
The organisation behind the controversial project explained that steam seen rising from the plant was due to its "hot commissioning works", where they used temporary oil burners to dry out refractory bricks.
"Following the boil outs the boiler tubes and piping will need to be cleaned out using steam. Again steam will be visible from the facility and there may also be some noise associated with this operation", a statement explained.
No waste has yet been burnt at Poolbeg, and the company says any waste delivered so far has been used to just get the weighbridge and cranes into action. Dublin Waste to Energy says it will send out a further information bulletin closer to when first fire of waste will commence.
The Poolbeg Incinerator is expected to provide enough electricity for 80,000 homes by the end of May, but many residents remain opposed to the development, which was first proposed 20 years ago.
Green Party leader Eamon Ryan has called for "absolute transparency" and believes real-time information "should be displayed both online and in a public location close to the facility."
"There are real concerns about the control of dioxins from incineration", he added.
Dublin Chamber, the group which represents businesses in the capital, has welcomed the opening of the incinerator. Mary Rose Burke believes the incinerator "will have a positive effect on the cost base for Irish business".
"Incineration is recognised globally as an effective method of waste management. Ireland's recycling rates have dramatically increased in recent years and the new incinerator will help ensure that Ireland meets the EU target to reduce landfill", she said.
