Adrian Kane also raised concerns about the impact of the proposed sale on workers' rights.
SIPTU representatives met with major opposition parties this week to discuss the privatisation of Bord na Móna Recycling which is headquartered in Newbridge.
Adrian Kane, SIPTU Divisional Organiser, has described the privatisation move as "gombeen politics."
He pointed out that the proposed deal would transfer control of the public service to Killarney Waste Disposal, a company that is not required to disclose its financial accounts due to its unlimited status.
Kane also raised concerns about the impact of the proposed sale on workers' rights.
Speaking on Kildare Today, he warned that the terms and conditions of employees, including their right to collectively bargain, would not be guaranteed under the share deal structure.
