The evaluation of waste streams
The knowledge Waste management plans start from the
knowledge of the local situation For waste management knowledge means:
Production Management
Production: Kind of producer:
Household Industrial waste
Quantity of waste Composition of waste Collection system
An example: the waste management plant in Veneto
The plan is divided in two main chapters: Urban waste
State of the art Evaluation of needs Proposal
Industrial waste State of the art Evaluation of needs Proposals
The urban waste: which data?
Total urban waste production District/Provinces Production Geographical effects (tourism
and economy) Level of separate collection Production of separated waste
(paper, plastic, metals…) Composition of residual waste
Who collect these data? Urban waste production data are
collected by waste management company
ARPAV is the webmaster of the collection system and use these data to draft the regional plan and check its enforcement
ARPAV calculate also the official level of separate collection for each municipality. The landfill tax is based on the achievement of SC targets
Right knowledge = right planning
Based on waste production trends it possible to foresee the lifetime of disposal plant as landfills
Based on waste composition it is possible to foresee the production of secondary raw material from separate collection and the installation required to the treat these streams.
Geographical knowledge of production site allow to reduce the distance between production and treatment
Some kinds of plants (composting, Anaerobic Digestion, WtE plants) have minimum sizes below which the maintenance costs are unbalanced
The role of national law In Italy data collection on waste production and waste management is
mandatory since 1997 The national law on waste in Montenegro it was adopted in 2011
The national law define only the main target The specific systems are defined in some administrative acts
