RECLAMATION-RECOVERY OF QUARRIES-MINES-LANDFILLS

Renaturation of an abandoned quarry in Lentini (Sicily island), obtained without watering and without use of topsoil, biomats,geonets, geomats, geocells, mulch, wood fiber matrix sheets, etc…

 

RECLAMATION-RECOVERY OF QUARRIES-MINES-LANDFILLS.  The environmental restoration of contaminated sites and old landfills often turn out to be very difficult, mainly because plant species used for the renaturation of sterile and/or contaminated soils don’t take roots easily.  Over the years several techniques have been developed for soil protection and renaturation.  Among these there is an emerging innovative technology that uses only natural herbaceous perennials plants with deep rooting system, and allows to operate in areas where climatic conditions were until a few years ago considered prohibitive for the development of vegetation: barren lands, altered or fractured rocks, soils treated with addition of lime up to 5% by weight, soil polluted by waste, hydrocarbons and heavy metals in concentrations up to 10 times higher than the upper limits admitted by law. In addition, these herbaceous plants show the ability to withstand high temperatures produced by the fermentation of organic waste in landfills.

RECLAMATION-RECOVERY OF QUARRIES-MINES-LANDFILLS. The range of grounds that can be treated with PRATI ARMATI®  include all the soils and rocks that, thanks to characteristics such as fracturing grade, macrostructure, texture, granulometry, compactness etc., allow development of root apparatus, for example:

SOILS

• clays
• silts
• sands
• gravel

and any mixture of these materials in different proportions

ROCKS

• conglomerates (slightly cemented)
• marls (weathered)
• Limestone (slightly cemented)
• flysch
• pyroclastites
• schists
• acid or basic rocks altered or highly fractured

RECLAMATION-RECOVERY OF QUARRIES-MINES-LANDFILLS. Root development may be obtained even in soils that in pedological terms are sterile.

RECLAMATION-RECOVERY OF QUARRIES-MINES-LANDFILLS. PRATI ARMATI® take root also in lime added soils (up to 5% in weight).

RECLAMATION-RECOVERY OF QUARRIES-MINES-LANDFILLS. Rocks must be altered or fractured to a sufficient extent, and the percentage of success in root development is proportional to the degree of alteration and fracturing.

RECLAMATION-RECOVERY OF QUARRIES-MINES-LANDFILLS. On compact and undamaged rocks root development is impossible.

Which pedoclimatic conditions PRATI ARMATI® can withstand

  • adaptable to extreme soil and climatic conditions within a temperature range of –45°C to +60°C, resistant within a pH range between pH 4 and pH 11
  • climates from  very dry to very wet;
  • on practically any lithotype and climate, even on most barren ground types: clay, silt, sands, gravel, flysh, lime added soils, granular soil ridges without top soil, and so on;
    • on soils polluted by hydrocarbons and heavy metals;
  • on salty soil
