Hera Group forms partnership with Quadrifoglio

Outcome of the call for tenders
The process launched by Quadrifoglio in May 2009 to identify a private minority shareholder/industrial partner for the creation of the NewCo tasked with the design, construction and management of a waste-to-energy plant in Case Passerini, in the municipality of Sesto Fiorentino, was concluded with the selection of Hera Group, accompanied by a pool of banks set up by Banca Infrastrutture Innovazione e Sviluppo S.p.A. (Intesa SanPaolo Group) and MPS Capital Services Banca per le Imprese S.p.A. (Montepaschi Group), as the partner capable of fully meeting the requirements set out in the call for tenders.
The decision to use a single call for tenders to identify an industrial partner capable of ensuring the necessary expertise and trustworthiness means that we now have a technical/architectural plan and a managerial/organisational plan that will ensure that the targets of environmental, energy and economic efficiency are met to the greatest extent possible.
Thanks to this first step, the need set out in the Provincial Plan to complete the integrated waste management cycle can be met within the next few years.
The Provincial Plan provides for an integrated system for the entire Central Tuscany area, where one of the essential elements for our region's autonomy is the Case Passerini waste-to-energy plant.

Incorporation of the NewCo
The coming weeks will see the creation of NewCo Q.tHermo, which will be 60% owned by Quadrifoglio and 40% owned by Hera Group, and will require the applicable legal authorisations before beginning construction work. Q.tHermo will therefore be responsible for applying for an Integrated Environmental Authorisation and Environmental Impact Assessment, the first step towards building the plant. Q.tHermo will also carry out, based on the standards defined by the control bodies, a preliminary check on the environmental matrices.

Execution costs
The amount awarded is Euro 134,480,250.00 plus VAT. The work will be carried out with the help of dedicated financing.

The plan: a plant that fits in perfectly with the urban and cultural context of the region
The tender specifications and the quality of the offer submitted mean that we already have a complete and definitive plan that will be able to obtain the various authorisations needed before being subjected to scrutiny by the community as a whole. Transparency and professionalism are the hallmarks of the work carried out so far, which will be completed in the coming months.
Work carried out in 2009 by teaching staff and students from the Industrial Design Department of the Faculty of Architecture at the University of Florence analysed the morphology of the region and examined how best to make the new plant fit in, both environmentally and architecturally. The results of the students' work were included in the tender material, because we are aware that the new waste-to-energy plant will, for the entire Florentine Plain, be one of the major “symbols” of the modern urban landscape. The aim is to build an industrial plant to service the community that will be capable of fitting in and representing the entire region.
The design produced by Gae Aulenti, one of the world's most prestigious architectural firms, has captured that spirit perfectly, creating a plant architecture that is evocative of history whilst also suggesting a vision of the future. It is an exquisite overview of the elements that characterise the artistic and architectural history of the Florence area, but also looks to develop it into a modern architectural artefact.

The best technologies to optimise environmentalperformanceand energy recovery
The plant will comprise two lines and, in compliance with industry planning, will have a treatment capacity of 136,760 tonnes per year (around 400 tonnes per day), equivalent to around 40% of the waste remaining after separated collection. The plant, which will employ around 50 direct and indirect staff, will be built using the best available techniques in order to obtain the best possible performance in terms of both environmental management and energy recovery.
The main technological features of the new plant include: automatic control of grid movement, fine-tune adjustment of the combustion air mix and continuous analysis of all combustion flue gas intermediate pollutants for more effective regulation of reagents, and greater air purification system efficiency.
The technologies used, including the double flue gas treatment system, will ensure that the new waste-to-energy plant's emissions are well below the legal limits. With regard to energy recovery, the plant will be equipped with a generator with a rated power of 17.6 MWe, which will therefore be able to produce around 125 GWh of electricity per year. A total of 106 GWh of this electricity will be sold to the network, covering the annual electricity consumption needs of around 40,000 households.

The Hera Group centralised monitoring system: emissions data on the web
The Case Passerini waste-to-energy plant will be supported by the Hera Group Centralised Plant Supervision System, one of Europe's leading technological facilities in the sector. The system, which is capable of carrying out continuous monitoring of the main process and production parameters, is one of the most important management and control tools currently available and can be used to guarantee maximum production efficiency and minimum environmental impact. Moreover, Q.tHermo's technicians will become part of a highly specialised network capable of providing technical and organisational support throughout the various plant management stages.
The data from the continuous emissions monitoring at the new waste-to-energy plant will be available online: users will be able to monitor flue stack emissions in real time by visiting the dedicated website. This further reinforces the plant's desire to be the “glass house” on the Plain.

Timetable
The next few weeks will see the formal incorporation of Q.tHermo, which will apply for the necessary authorisations. The authorisation issuance procedure will be organised by the Province of Florence, which is responsible for issuing all the authorisations needed to execute and manage the work. Taking the work schedules into account, the waste-to-energy plant should become operational in late 2015, when it will run for a one-year monitored testing phase in order to carry out a precise on-site check of its expected performance values.

Hera Group
Hera Group, via its subsidiary, Herambiente, is Italy's leading operator in the environment sector thanks to a total infrastructure comprising 80 waste treatment and disposal plants (waste-to-energy plants, landfills, composting plants, sorting facilities, chemical/physical treatment plants, etc.). In 2011 Herambiente treated around 5.7 million tonnes of waste and generated 680 GWh of electricity, including 580 GWh produced by waste-to-energy processing.
It currently operates six waste-to-energy plants for urban waste and non-hazardous special waste, located in Modena, Bologna, Ferrara, Ravenna, Forlì and Rimini.
