People Before Profit has called on the Government to abolish a new pay-by-weight waste collection scheme for green bins.
It was introduced by former environment minister Alan Kelly in the last weeks of his ministry.
Richard Boyd Barrett said it was an "absolutely disgraceful" action by Mr Kelly.
He said that the move will be "extremely damaging" to the environment, discourage people from recycling and encourage more illegal dumping.
Deputy Boyd Barrett said the only beneficiaries would be private and for-profit waste operators which would result in "environmental sabotage".
Mr Kelly previously stated that the new charge would reduce costs for 87% of homeowners if they sort their waste properly, but Mr Boyd Barrett said: "I don't think we can believe Alan Kelly at all".
He said if the charges are introduced, it shows extreme environmental hypocrisy on Mr Kelly's part.
Deputy Boyd Barrett also denied that the PBP's campaign against the green bin charge is not a move towards a full anti-tax campaign.
He said the PBP want fair and progressive taxation to fund Ireland's public services.
The campaign against the charges is also supported by Sinn Féin and by Fianna Fáil.
Fianna Fáil TD Darragh O'Brien said his party would oppose the move at local authority level.
