The workers union has been campaigning against the closure of the waste collection service.
SIPTU say the potential sale of Bord na Mona Recycling is "untenable" based on the findings of the latest EPA report.
Rumours have been circulating for months over the possible sale of Ireland's last remaining waste collection service to not be brought under the private sector.
SIPTU say Ireland stands alone in allowing domestic waste collection services to compete side by side in local authority areas.
Their Transport, Energy, Aviation and Construction Divisional Organiser, Adrian Kane says a meeting has been arranged with midlands TDs on Thursday:
