Ronchi Decree

Decree n. 22 known as Ronchi Decree comes into force in Italy on 5th February: waste management 
has been recognized as activity of public interest and the first classification of waste and definition of waste management processes have been introduced.


The history of Promeco dates back to 1996 when its founders Elena Triaca & Paolo Rebai, thanks to a managing background at international level, decided to invest in environmental field anticipating the needs of the market.


It was the time when Maastricht treaty set environmental protection among the main aims of European Community and when companies, authorities and customers begun to face the issue of waste in the name of common responsibility.

One year later, in 1997, Decree no. 22 known as Ronchi Decree, came into force in Italy and it acknowledged waste management among the activities of public interest and set the first classification of waste in Italy along with the settlement of management processes.

Thanks to a close partnership with the historical plant engineering company UTL from Wien, Austria, Promeco achieved experience and know-how and specifically focused on composting and anaerobic digestion fields.


Among the first references, to be counted are composting and AD plants with biogas production in Salzburg that were and example of excellence at that time: they effectively treated and enhanced OFMSW both technologically and as built, since they were perfectly integrated close to the residential area.  


Since then, Promeco has increased its know-how and gained expertise thanks to its richness: innovation and creativity, that still are its identification marks.

The Company, with passion and perseverance, facing with the needs of the international market has diversified its production developing single machineries for recycling and full processing lines in different fields over time.
