Treatment and disposal of solid urban and special waste and liquid waste
The CIPNES "Gallura" complex plant (IPPC Complex "Integrated Pollution Prevention and Control") , located in Loc. Spiritu Santu - Olbia (SS), is a platform dedicated to the treatment, mainly aimed at the recovery and marginal disposal, of urban and special non-hazardous waste coming primarily from the former province of Olbia Tempio.
This complex consists of the following plant sections:
- Landfill for non-hazardous waste (SECTION A)
- Mechanical biological treatment plant (T.M.B.) for undifferentiated waste - SECTION B-C;
- Quality composting plant - SECTION D;
- Platform for the valorisation of undifferentiated waste - SECTION E (divided into 5 subsections);
- Waste energy plant for landfill biogas - SECTION F;
- Bulky waste platform - SECTION G.
The CIPNES policy related to the management and development of this platform aims to ensure an important public service for the territory, pursuing the Community guidelines on waste management and treatment. The achievement of the future goals foreseen by the CIPNES is connected to the continuous development and adaptation of the Platform, in order to ensure an actual service with particular attention to the environment protection, the impacts minimization produced and the awareness of the different stakeholders.
Water service - potabilization
The Provincial Industrial Consortium of Gallura, has built and manages the networks and technological plants related to water purification and drinking water purifying, in the pursuit of a sound economic management.
The integrated consortium water service is divided into three subsectors:
1) rough water purification
(2) waste water purification
(3) maintenance and management of water and sewerage networks
Energy generation infrastructure
A few years ago Cipnes launched an infrastructural programme for the production of electricity from renewable sources through a series of interventions and works which, in line with the most recent guidelines on territorial planning, do not foresee the expansion and further "consumption" of land, but the redevelopment of the already anthropized and settled spaces.
The Consortium has realized:
- a 1000 KWp photovoltaic system at a part no longer active and now undergoing environmental remediation of the consortium landfill of Spiritu Santu.
The plant, which covers an area of about 40,000 square meters, is part of a project of ecological redevelopment and energy efficiency and enhancement of the consortium landfill plant area through the production of energy from photovoltaic solar energy source that makes the pair with the existing plant for the energy recovery of biogas produced from waste. The estimated annual production is around 1.1 Gwh, the equivalent of the annual energy needs of 1000 people, for a total estimated revenue for the entire economic life in 8 million euros.
- A photovoltaic field inside a disused quarry.
The plant covers a total area of about 20,000 square meters. The estimated annual production is around 1.2 Gwh, the equivalent of the annual energy needs of 1100 people, and a total estimated revenue for the entire economic life of 8 million euros.
The construction of an "anaerobic digestion" plant for the production of biomethane from the biogas produced by the treatment of organic and special urban waste is planned. The biogas derived from the anaerobic digestion of biomass from the "digester" will be subjected to a purification and upgrading process to be transformed into biomethane suitable for feeding into the city's natural gas network and also transferable to the consortium industrial area of Olbia to meet industrial energy needs.
The new anaerobic bio-manager plant of the organic fraction of urban waste (centralized cogeneration of heat and energy), currently under design, will be able to treat about 40,000 tons of organic waste, and 20,000 tons of agricultural waste and dedicated plant essences every year, and to deliver about 500 standard cubic meters per hour of biomethane, or more than 50% of the total gas needs of the city of Olbia and its industrial area also for the incentivated generation of heat.
