WTE Trieste Trigeneration Plant

Trieste has a long tradition of managing waste through energy recovery plants. Today the city is served by Errera 3, a waste-to-energy incinerator that converts the heat of combustion into clean energy.

Errera 3 grew out of Errera 2, which ran two incineration lines of 204 tonnes of waste per day each and a thermal cycle for energy recovery feeding a 4.85 MW steam turbine, producing 32 GWh of electricity per year.

The original plant was modernised with a third waste treatment line and an entirely new thermal cycle serving all three lines, with a 14.9 MW steam turbine able to produce 100 GWh per year.

BIMON was tasked with creating and coordinating all digital models and simulating the construction phases and methods of the project's components. We supported the client with Project BIM Management consulting, meaning project planning, management and monitoring, and with BIM modelling in the construction phase.

By combining BIM models with construction simulations, we detected and resolved clashes before they became problems on site. Hera Group's approach let us optimise construction activities and keep the project on schedule.

Monitoring was planned around the needs of the job site, with surveys and up-to-date as-is models.
