Recupero di materia ed energia dalle acque reflue attraverso la simbiosi industriale WtE nelle regioni del Sud Europa

Industrial symbiosis represents a strategy for optimizing the use of resources that involve companies, in order to generate competitive advantages through the transfer of resources, such as materials, energy, water, spaces, skills, etc..

Industrial symbiosis models

IS ex changes are planned and design at the beginning.
This approach is characterized by the implementation in industrial areas or districts of symbiotic.
The system of relations between companies arises independently of a specific programming,
IS ex changes are individuated at regional scale thanks to models and tools aimed at allowing the meeting between demand and supply of resources.
In a scenario characterised by barely-effective separate waste collection ,most of the organic fraction of the municipal solid waste (OF-MSW) produced by the millions of inhabitants intheseregions-especiallyinlargemetropolitanareas-isstilldisposed of in landfills. directly or after a mechanical biological treatment (MBT)of the unsorted waste.

Many of these areas also suffer from a historical water scarcity, the effects of which have progressively intensified as a result of the climate change.
Therefore, the availability of marginal water resources could be crucial to satisfy the future water demand for agriculture .
However, the cost of treating waste water to achieve the required water quality for reuse in agriculture still makes the price of this unconventional resource too high,compared to conventional resources.

Further more,many waste water treatment plants (WWTP), in these regions, suffer from severe problems,related to the treatment and disposal of the produced sludge.
