Belvedere Spa: projects, development, innovation
A BET WON
The company Belvedere S.p.A. was founded in 1997, on the initiative of the Municipality of Peccioli, from the need to secure an unmanaged landfill in the hamlet of Legoli that collected waste from six municipalities in the area.
Over the years Belvedere Spa has become a point of reference for planning, innovation, and development of the territory and together with the Municipality of Peccioli and the Peccioli Foundation forms the Peccioli System.
WASTE DISPOSAL PLANT
In 1988 in an area of Legoli, as in other places in the province, an unmanaged landfill had been created in which waste from six neighboring municipalities flowed, so the Municipal Administration decided to transform the problem into an opportunity for development by fully embracing the P.I.M.B.Y. (Please In MY Back Yard) philosophy.
The old site was reorganized into a real industrial activity and made available to the competent bodies to avoid emergency situations in waste disposal.
In 1997 Belvedere S.p.A. was created for the management of the Legoli waste disposal plant.
MBT WASTE TREATMENT PLANT
The mechanical-biological treatment plant (MBT) has been in operation since 2015. It treats undifferentiated municipal waste and receives waste deriving from the treatment of undifferentiated municipal waste, to be stabilized in bio cells.
HOW MBT WORKS
It is a cold treatment technology for undifferentiated waste (or residual waste after separate collection) that combines mechanical processes and biological processes and allows to separate the wet fraction (organic to be bio dried) from the dry fraction.
- A mechanical sorting line shreds the undifferentiated waste and screens it to separate the waste into two fractions depending on its size (over sieve and under sieve).
- From these fractions the metallic materials are extracted to be sent for recovery.
- Over sieve can be sent directly to the landfill.
- The under sieve, the richest in organic compounds, is instead sent to another section of the plant to be subjected to bio stabilization treatment in the appropriate bio cells, within which the natural action of the bacteria allows the complete fermentation of organic substances within about three weeks. At the end of the treatment there is a stabilized material with a very low moisture content that can in turn be sent to the landfill.
On June 28, 2016 the colourful and fun “wind tunnel” was inaugurated, created by the artist Sergio Staino and his son Michele. The work consists of ten images reproduced on polycarbonate panels that enrich the approximately 8000 square meters of the mechanical and biological treatment plant (MBT).
From the cicada to the lizard and then again the Burgundian snail, the rhinoceros beetle, the turtle and many others “small animals that live among the clods, in the grass, in the marshes, at the height of the daisies, in fact”, as claimed by Staino himself, who in a procession drawn with ironic stroke and bright colours tell the tale of princesses and whores, pompous military men and brave knights, but also acrobats and musicians animating a habitual construction site with colours and presences. The ten subjects are inspired by a phrase by photographer Mario Dondero: “living at the height of daisies”, those daisies that the cartoonist has also caught all around the lawn surrounding the plant.
NEW ANAEROBIC DIGESTION PLANT
The project carried out and managed by the company ALBE s.r.l., 50% owned by Belvedere and 50% by Alia Servizi Ambientali, involves the construction of a treatment and recovery plant for the organic fraction of urban waste.
RENEWABLE ELECTRICITY PRODUCED
ELECTRICITY FED INTO THE GRID
RENEWABLE THERMAL ENERGY PRODUCED
Biogas, photovoltaic and wind are the renewable sources from which we obtain energy for us and to be fed into the national grid.
Biogas, i.e. gas – of which about 50% is methane – which is formed by the degradation process of the organic component of waste, is intercepted by several suction wells homogeneously distributed over the entire landfill area and used as fuel by the four Jenbacher cogeneration engines, transforming it into electricity. Three motors have the power of 625 kWh and one has the power of 511 kWh, so managing to produce a total of over 14 million kWh per year of electricity. Most of the energy thus produced is fed into the national grid and a small part is used for internal consumption of the plants.
ONE HECTARE OF SKY
In 2006 it was decided to build a 1,000 kWp photovoltaic system called “One hectare of sky” along La Fila road in the municipality of Peccioli.
In the renewable energy sector, it was the first project with popular participation, i.e. financed by the issue of a bond.
Therefore, all citizens have been given the opportunity to invest in the production of clean energy in a simple and direct way. The plant, which came into operation in 2008, consists of 5,500 photovoltaic panels, both monocrystalline and polycrystalline, and thanks to 198 inverters they can produce yearly over 1 million kWh of electricity, completely sold to the national grid.
Half of the financing of the plant was supported by Belvedere and half by about 350 bondholders who subscribed bonds with a yield of 5.5% and 6.5% with repayment of the invested capital at 7 and 12 years.
Near the “One hectare of sky” plant, production gardens have also been created on loan for free use to the citizens of the Municipality of Peccioli.

A SOLAR PROJECT
After the positive experience of the Peccioli photovoltaic system ” One hectare of sky”, in 2011 a second photovoltaic system called “A solar project” was built in the Municipality of Terricciola.
This project was also partly financed with the issue of a bond loan subscribed by about 300 bondholders, mostly from the territory of the Municipality of Terricciola.
The plant consists of about 1,800 polycrystalline photovoltaic panels and a single large inverter produces over 450,000 kWh per year of electricity sold to the national grid, with a peak power of 396 kWh.
