2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

Reconstitution of soils is a pedotechnique based on the treatment of organic and non-organic pedomaterials to achieve benefits in areas with barren, degraded, desertified and/ or sealed soils.

2.2 Detailed description of the Technology

Description:

Reconstitution of soils to generate an Anthroposol is a technology based on the treatment of organic and non-organic pedomaterials or “matrices” (from “matrix” in Latin: everything that is the foundation of something) to achieve ecosystem benefits, especially in areas with degraded, desertified, barren and/or sealed soils. The technology applies a conceptual model based on the production of new soil aggregates with targeted environmental and soil characters generated via a chemico-mechanical process that entails reusing residues of specific origin. The activity is consistent with the principles of a “Circular Economy”, applying restoration ecology, use of compatible waste and saving the non-renewable resource of soil. Reconstitution is covered by two patents of the mcm Ecosistemi s.r.l. company.
Reconstitution applies the process to two groups of pedomaterials. Firstly, primary matrices (matrices I), represent the main material to be converted into fertile soil. These could be degraded soil itself or inorganic mineral pedomaterials. Secondly, secondary matrices (matrices II) refer to byproducts and waste from production activities. Secondary matrices are divided into two. First, organic - from wood and cellulose processing production activities and from textile and agro-food industries. These are characterized by a high organic component with a high carbon/nitrogen ratio, and a high presence of plant fibres. Second, mineral matrices - especially from mining, the preparation of drinking and industrial water and the management of hydroelectric reservoirs and internal canals. There are four stages.
1) Loading: After the chemico-physico-environmental and rheological characterization of matrices I and II, the materials are selected according to the type of soil desired and then loaded in the plant. Dosage is calculated through an application program (PEDOGÉNIA), which estimates the chemical properties of the finished product.
2) Mixing: The matrices undergo mechanical mixing under controlled humidity.
3) Disaggregation: Breakup and defibering through rotating movements at variable power.
4) Reconstitution: Specifically calibrated cyclic compression and formation of reconstituted soil aggregates.
The treatment generates an Anthroposol whose characters and properties are different from the materials of origin.
The properties of the reconstituted soils and the technical-economic sustainability of the pedotechnology have been demonstrated over the years with agronomical tests and experiments, as well as comparative analysis between degraded soils and reconstituted soils. This demonstrates the reconstituted soil’s ability to create a stable pedosystem to carry out its basic functions - storage, filtration, transformation of nutrients and biodiversity pools - for various forms of land use, and ecosystem benefits. Agroforestry restoration with reconstitution has social impact, as it is demonstrated by a EU project (“New Life”), where the Park of Trebbia river has increased utility to people after restoration. Agronomic restoration allows farmers to increase yields using less fertilizer and water. Another environmental and economic advantage is that manufacturing companies which produce waste can reduce costs through the recycling process of reconstitution. For reconstitution, a plant has to be installed near the land to be restored; an overview is presented in 4.1. In addition, earth moving vehicles are needed for the transport and placement of reconstituted soil.

If land user bore less than 100% of costs, indicate who covered the remaining costs:

Costs related to the matrices to be used and transport (1125000.00 EUR) are covered by company producing waste used. The costs to dispose of matrices II are much higher than taking them to the reconstitution plant.

Comments:

degraded land value 0 EUR
restored area value 390000 EUR
restoration using allocation of natural soil (8 EUR/m3, cost of natural soil in Piacenza) added to transport costs = 2100000.00 EUR
restoration using reconstituted soil technology = 28536 + 30000 + 40000 + 250000.00 EUR because 1125000.00 EUR are covered by company producing waste and so not spent for restoration.

6.3 Exposure and sensitivity of the Technology to gradual climate change and climate-related extremes/ disasters (as perceived by land users)

Gradual climate change

Gradual climate change
Season increase or decrease How does the Technology cope with it?
seasonal rainfall wet/ rainy season decrease well

Climate-related extremes (disasters)

Meteorological disasters
How does the Technology cope with it?
local rainstorm well
Climatological disasters
How does the Technology cope with it?
extreme winter conditions moderately

6.4 Cost-benefit analysis

How do the benefits compare with the establishment costs (from land users’ perspective)?
Short-term returns:

positive

Long-term returns:

very positive

How do the benefits compare with the maintenance/ recurrent costs (from land users' perspective)?
Short-term returns:

positive

Long-term returns:

very positive

Comments:

The recycle of suitable waste materials used defrays the reconstitution technology in short and long term

6.5 Adoption of the Technology

  • 1-10%
Of all those who have adopted the Technology, how many did so spontaneously, i.e. without receiving any material incentives/ payments?
  • 91-100%

6.6 Adaptation

Has the Technology been modified recently to adapt to changing conditions?

Ja

other (specify):

the Technology is partly modified to face every restoration project

Specify adaptation of the Technology (design, material/ species, etc.):

design, matrices to be used

6.7 Strengths/ advantages/ opportunities of the Technology

Strengths/ advantages/ opportunities in the land user’s view
Strengths: to change soil class in Land Capability Classification, to improve soil workability, to create new soil aggregates (the organic matter is covered by fine soil mineral fractions)
Advantages: to increase soil fertility, to implement Circular Economy
Opportunities: to create a non-renewable resource (soil) and/or to restore it, to implement Circular Economy
Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view
Strengths: to produce the suitable soil for the environment where it will be placed
Advantages: to reduce the use of fertilizers
Opportunities: to restore soil using suitable waste, Circular Economy

6.8 Weaknesses/ disadvantages/ risks of the Technology and ways of overcoming them

Weaknesses/ disadvantages/ risks in the land user’s view How can they be overcome?
Weaknesses: restoration of soil in very steep slope studies about the physical behavior of reconstituted soil in steep slope
Disadvantages: demand exceed supply, concerning current number of workers employed in the reconstituted plant formation of new workers
Risks: crisis of industries producing suitable waste non-stop search for suitable waste to use
Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view How can they be overcome?
Weaknesses: restoration of soil in very steep slope studies about the physical behavior of reconstituted soil in steep slope
Disadvantages: contamined soils studies about possibility of using reconstitution to clean soils
Risks: the pedotechniques include all the anthropic activities that determine a growing influence of man on pedogenesis and pedolandscapes; they have to satisfy man needs while avoiding any undesirable environmental consequences (Dazzi et al., 2010).
This is the main core of reconstitution of soils, but sometimes, the use of waste material, even if, environmental suitable, isn't understood because of waste are considered materials only for disposal.
Dissemination concerning the laboratory analysis before the waste use, studies and research projects with University to test environmental suitability of reconstituted soils
