S.I.E.M. S.p.A.

The company derives from the transformation of C.I.M.E. (Consorzio Intercomunale Mantovano per l’Ecologia, a cooperative organisation responsible for waste management in Mantova), operating under Italian laws 142/90 and made up by 69 of the 70 Communities of County, as well as the Pubblic Administration of the County itself.

The members are therefore the Communities, which posses a percentage of shares proportional to their number of respective inhabitants, while the CountyAdministration has maintained the 1.5% that it originally possessed in the C.I.M.E. Cooperative.

It is therefore a joint stock company owned by public capital but statutorily predisposed to accept the investment of private capital, with the provision that territorial public bodies own 51% of shares.

The company can be defined as unique in nature for the following characteristics:

- derived from the transformation of a consortium of Public Bodies;
- covers the whole province;
- to fulfil obligations assumed from the councils when this transformation was approved, the company has the “monopoly” on urban solid and assimilated waste for the whole province.

These characteristics can be an irreplaceable tool of initiative and planning with the aim of permitting the self-sufficiency of the County in the collection, treatment and final disposal of waste.

Another positive consequence is the possibility of self-sufficiency, containing costs or completely transferring eventual profits to the reduction of waste disposal fees applied to residents by the councils.

The mission of the Company is sufficiently wide as to allow interventions on the whole problem of ecologically safeguarding the environment of the whole national territory, with the necessary commercial, industrial and financial operations.

The company has the task of collection, recuperation, transformation, transport, and discharge of all types of waste with controlled management of discharges and plants with complex technology, as well as all activities inherent to urban hygiene.

PRINCIPAL ACTIVITY

Management of collection services and solid urban waste transport also coming from separated collection, for member councils.

Management of the selection and treatment plants of urban solid refuse (RSU) for the production of Refuse Derived Fuel (RDF) and compost, situated in the locality of Villa Cappella (Ceresara) and Pieve di Coriano.

Management of the of quality compost plants for the treatment of vegetal waste coming from separated collection in the locality of Villa Cappella (Ceresara) and Pieve di Coriano.

Management of the bulky urban waste treatment plant and dry parts storage from separated collection in Castelgoffredo in the locality of Villa (Mn).

Management of exhausted Waste Stockage Area situated in Monzambano, Magnacavallo and Pieve di Coriano.

PROCESSING PLANTS OF UNSEPARATED R.S.U.

The R.S.U. treatment plants have been active since 1977, underwent important modernisations in 1985 and in 1991, and are now undergoing new restructuring work.

The plants have currently been in activity for 6 days per week for about 312 days a year, in three shifts of work.

PLANT POTENTIAL

The authorised plants are able to treat solid urban waste and some typologies of assimilated refuse.

The potential of any plant is of about 240 tons per day of R.S.U., equal to around 75,000 tons per year.

Therefore it is able to treat all unseparated R.S.U. that has been collected and produced in the province of Mantova.

PRODUCT RECOVERED AND DESTINATION

Products	Percentage	Destination
Urban Solid Wastes not subject to treatment	2%	final disposal
processing waste	23 %	final disposal
Refuse Derived Fuel	35 %	energy recuperated
Lower Quality compost	10%	recuperated environmental
Agriculture Compost	7%	amendment used in agricultural practices
Metallic Materials	1%	recuperated
Inert Material	2 %	recuperated environmental
Loss of process	20%

The balance is indicative and refers to annual averages, in as much as it is strongly influenced by elementary composition and by the humidity of materials entering and leaving.

PREDICTED RESULTS

The development project will reduce to the minimum indispensable the need for landfills, in this way reserved for waste processing only.

In awaiting the foreseen facility of a RDF combustion plant for the production of electrical energy, the RDF will be utilised by private companies already equipped with plants for the production of energy for internal consumption localised in the province.

NORMATIVES

What is necessary is an update of the normative that offers incentives for the use of alternative fuels to companies (in particular cement works) without increasing costs for the producers of those fuels.
