They called for a meeting in May.
SIPTU are criticising the Minister for the Environment for failing to yet meet with representatives to discuss the possible sale of Bord na Móna Recycling.
The organisation called for a meeting with the Minister Eamon Ryan at the end of May following reports of the State planning to sell off the last remaining publicly owned recycling and waste company in Ireland.
Transport, Aviation, Energy and Construction Divisional Organiser with SIPTU, Adrian Kane says the current 'chaotic' waste service system has caused heavy traffic and fly tipping.

In a statement to Midlands 103, a Bord na Móna spokesperson says:
"Bord na Móna are currently carrying out a strategic review of the Bord na Móna Recycling business. It is business as usual, and this will not affect our ways of working, or our commitment to providing an efficient waste collection service for our customers. We will not be providing further comment at this time"
