WTE Trigeneration Plant

Trieste - Italy






12.000 sqm


In progress


Hera Group’s trigeneration plant underwent a renovation and expansion to make space for new machines and equipment. BIMON was tasked with the creation and coordination of all digital models and simulations of the phases and construction methods of the components included in the project.


Project Background

The city of Trieste, now served by the plant called “Errera 3,” has a very long tradition of waste management through energy recovery plants, such as modern waste-to-energy plants.


“Errera 3” was born as a natural evolution of “Errera 2,” which was structured on two incineration lines of 204 tons/day of waste each and a thermal cycle dedicated to energy recovery serving a 4.85 MW steam turbine capable of producing 32 GWh/year of electricity.

The original plant was modernized and modified by building a third waste treatment line and an entirely new thermal cycle serving all three lines for energy recovery with a 14.9 MW steam turbine capable of producing 100 GWh/year.

The Trieste waste-to-energy plant is a special type of incinerator capable of converting the heat generated during combustion into clean energy.



Simulation and Clash Detection

Thanks to the innovative approach of Gruppo Hera we successfully optimized the construction activities on the WTE Trieste project, ensuring a seamless adherence to the schedule. Combining BIM technology with advanced simulations, we are able to proactively resolve clashes and eliminate problems on-site even before their appearance.
