2. Executive Summary The CLEANSED project demonstrated and evaluate an innovative, integrated, multisector approach for the smart and sustainable management of polluted dredged river sediments to be reused in two different sectors: 1) road construction as a filling material 2) plant nursery as a substrate/amender.
The project brings together the problems and needs of three different sectors (management of dredged sediments, plant nursing, road building), demonstrating an innovative and fully sustainable set of strategies that allows public and private stakeholders to face their existing challenges in new and more effective ways.
The CLEANSED approach has been demonstrated within an integrated basin system in the Tuscany region, Italy, showing how to achieve a higher, cost-effective integration of local and regional production systems, with sediments used within the same basin as the river/canal.
1) Road construction After a preliminary characterization of some sediment samples dredged in different location of the Navicelli canal, the more idoneous sample was selected and dredged in the quantity of about 800 m3.
The dredged material was deposited in a Navicelli basin, and on the bases of chemical physical properties, undergo to a landfarming process (selected as more appropriate technology enables to reduce water content, organic matter and organic contaminants).
The analysis carried out on the sediment after about five months of landfarming confirmed the general suitability of the sediment for its reuse in road construction.
Because of the great content of water, the sediment needed another post treatment consisting in the use of lime; in addition, and since the sediments were classified in the A7-6 group, they were used in the body of the embankment. A 100 m long road has been constructed; the monitoring activity confirms the suitability of the sediment for road construction.
Some delays in the above actions have been due to: 1) need of burocratic permissions for fresh sediment disposal, 2) a longer period of fresh sediment landfarming treatment, 3) adverse weather conditions (rainy winter). Despite of these bureaucratic and technical problems, the activities have been carried out as planned in the proposal.
2) Plant nursery For plant nursery purpose, sediments decontaminated with plants (phyto-treatment) and organic amendment in the framework of a previous European project (AGRIPORT ECO/08/239065/S12.532262) were used.
The results of the characterization suggested the need to subject the sediments to a landfarming treatment with the aim to homogenize the substrate, to increase the biological activities and, as a consequence, to further reduce the organic contamination.
Two months landfarming process were particularly effective in improving biological activity and further decreasing organic contamination in the sediments; however, due to the lower nutrient content and water holding capacity, a mix of sediments with an organic matrix, such as agronomic soil, has been necessary. Three different matrices were prepared for nursery activity
-T0 = CTL (control) = Decontaminated river sediment (0%) and agronomic soil (100%)
-T33 = Decontaminated river sediment (33%) and agronomic soil (66%),
-T50 = Decontaminated river sediment (50%) and agronomic soil (50%) Final report LIFE+ ENV/IT/000652- CLEANSED Three ornamental species were selected: Photinia x fraseri, RobinViburnum tinus L., Eleagnus macrophylla L.
In order to assess the suitability of sediment in plant nursery activity, the mixtures were monitored through periodical chemico-physical and biological measures. In addition, plant growth and physiological stress have been also regularly evaluated. The results obtained at the end of the experimentation, confirmed the suitability of sediments in plant nursery activity since plant growth and their physiological response were equal (for Eleagnus macrophylla and Photinia x fraseri) or better (Viburnum tinus) than those found using a traditional agronomic soil. A percentage of 33% decontaminated sediments in the mixture (soilsediment) gave also the best performance, for some species, in terms of root vitality.
At the end of the project, the following objectives are achieved:
About 800 m3 of sediments were dredged from the Navicelli canal (Action B1).
The fresh dredged sediments to be reused in road construction and the sediments already treated with Agriport phyto-tecnology were characterized by chemical, physical and biological point of view (Action B1).
The landfarming treatment used alone or a post-treatment were defined as the more suitable treatment for both sediments (Action B.1).
The sediments were characterized by chemical, physical and biological point of view during the whole landfarming process (Action C 1).
The selected landfarming methodology was effective in the decontamination (reduction of organic pollutant of about 95% in dredged sediments) and the transformation of sediments in matrices reusable in road and nursery activities.
However, due to the lower nutrient content and water holding capacity, a mix of sediments with an organic matrix, such as an agronomic soil, was suggested for nursery activity. Instead, in road construction was necessary another chemical treatment in order to further reduce the water content (Actions B.2 and C.1).
The trials in nursery activity were set up preparing 6 cold frames of about 3m3 each
with three substrates:
T0= agronomic soil (100%), 4 replicates T33 = Decontaminated river sediment (33%) and agronomic soil (66%), 4 replicates T50 = Decontaminated river sediment (50%) and agronomic soil (50%), 4 replicates Three ornamental species have been selected: Photinia x fraseri var. Red Robin;
Viburnum tinus L.; and Eleagnus macrophylla L. 48 plants for each species were used, for a total of 144 plants Aggregating power of the sediments on the soils, assessment of the hydraulic characteristics of the mixture, and growth and qualitative features of plants were demonstrated (Actions B.3).
The suitability of sediment (different mixtures sediment-agronomic soil) in plant nursery activity were tested and monitored through periodical chemico-physical and biological analyses of the agronomic substrate, growth and physiological stress of plants (Actions C.2).
The sediments mixtures resulted suitable for in field cultivation of shrub species since plant growth and physiological response were equal (for Eleagnus macrophylla and Photinia x fraseri) or better (Viburnum tinus) than in the agronomic soil traditionally exploited for plant nursing. A percentage of 33% decontaminated sediments in the Final report LIFE+ ENV/IT/000652- CLEANSED mixture gave also the best performance, for some species in terms of root vitality.
A 100 m long road was constructed with treated fresh sediments after another chemical treatment consisting in the use of lime in order to further reduce the sediment water content. Since the sediments were classified in the A7-6 group, they were used in the body of the embankment (Actions B.4).
The monitoring activity carried out confirmed the suitability of the sediment for road construction. (Actions C.3).
In this Final Report the chapters 3 and 4 present the technical and administrative topics and organisations of the project; while, in the chapters 5 and 6 technical and financial results obtained at the mid-term period of the project are reported.
3. Introduction Environmental problem/issue addressed Every year in Europe 130 million m3 of polluted river sediments are dredged and need to be disposed of in specific and expensive ways (up to € 7.000/ton). Every year 5.2 million m3 of soil are removed from the ground due to plant nursing activities. To prevent the risk of a tendency which would lead to a 8-10 mm/year lowering of the ground level, plant nurseries are forced to buy soil from third-party catchments, which are often of poor quality and contribute to soil exploitation elsewhere. Similar problems are faced by the EU road building industry, whose yearly demand for sand, gravel and aggregates for stability and draining purposes is around 30 million m3, for an average value of € 450 million.
The CLEANSED project shows how polluted dredged river sediments can be treated and used within two different production processes in an ecologically and financially advantageous way: the sediments are turned from a valueless and expensive waste into a valuable raw material, guaranteeing the full environmental and financial sustainability of the approach. The physical-chemical characteristics of decontaminated sediments make it possible to smoothly include them in current production processes.
Outline the hypothesis demonstrated by the project The CLEANSED project demonstrated, evaluated and disseminated an innovative, integrated, multisector approach for the smart and sustainable management of polluted dredged river sediments.
Polluted sediments were dredged, transformed from a contaminated waste into a valuable material via a specific decontamination treatment, and then put to productive use in two
1) plant nursing: decontaminated sediments were used as a substrate/amender to prevent the loss of soil and biomass due to plant nursing activities;
2) road construction: decontaminated sediments were used as a filling material for the construction of roads.
The whole cycle took place within a real natural and productive district, i.e. the basin and alluvial plains of the Arno river, Italy.
Description of the technical solution The implementation of CLEANSED has involved the following main actions: dredging, analysis and characterization of contaminated sediments; sediment treatment; demonstration Final report LIFE+ ENV/IT/000652- CLEANSED of the use of decontaminated sediments as a substrate for plant nursing; demonstration of the use of decontaminated sediments in road construction; technical and economic impact assessment, drafting of guidelines for the use of decontaminated sediments. Monitoring actions have also been included in the work plan to ensure the accomplishment of project objectives.
