In 2017 we continue to develop/improve plant equipment in the following sectors:
- energy recovery of landfill biogas;
- energy recovery in the form of biofuels (biomethane) obtained from the organic fraction of separated waste;
- roduction and efficient use of electricity;
- greater recovery of plastic used to produce of new products;
- creation of new landfill volumes for residual waste components that cannot be used in any other way.
In 2017, we obtained construction and operation permits for the S. Agata Bolognese biomethane plant and construction on civil works and digesters began in April. The works carried out in 2017 on this site amounted to €12.2 million. At the same time, we also contracted the other components (upgrades, electrical systems, mechanical systems, etc.) that are being built in the factory and for which assembly is expected to take place in 2018.
In addition to these activities, the Herambiente Group made operational investments of a further Euro 43.2 million in the material and energy recovery sector, as well as in the construction of further landfill volumes; the most important of these include Alimpet’s new PET washing line, the revamping of the boiler at the Pozzilli waste-to-energy plant, the implementation of energy recovery systems with biogas engines at the Imola and Ravenna landfills, the revamping of plant sections at the Cesena and Ozzano composting plants to bring them into line with BATs, the Best Available Techniques.
In 2017, in relation to glass treatment and recovery, we obtained permits for the construction and operation of the line that will replace the existing line at the Rimini selection plant. In 2017, we initiated the procedure to award of the provision and installation of the line. The procedure will be completed in 2018, and assembly and commissioning of the line will also be carried out during that year. In 2017, the company was granted authorization to implement a storage plant in Modena; the plant was built and started operating at the end of the year.
Below is a summary of some of the main environmental measures being designed, in progress or completed at the end of 2017. These 18 measures are worth about Euro 150 million.

Among the plants managed by the Group, note that as described below, we have enlarged the Tre Monti landfill (near Imola), run by the Conami consortium, the owner of the landfill.
