SubsTer® alternative topsoil

Subster® is a soil engineering process for the formulation of alternative topsoil using quarry by-products or inert excavation earth from construction sites. This topsoil is sold to landscaping companies, contractors and public developers. It is an alternative to the use of soils from agricultural land and natural areas, for resources preservation and circular economy implementation.…

Soil and ecological engineering, plant-based engineering

For the production of topsoil, soil improvement and restoration of degraded soils we apply different approaches depending on the case and the needs of our customer: Soil engineering, resulting into the formulation to produce a topsoil valorising the materials present on site (including excavated earth); Ecological engineering, or the use of ecosystem properties (living soils)…

Phytoremediation and phytostabilisation

Phytoremediation is based on on-site pollution treatment by plants cultures. The objective of phytostabilisation is the reduction of pollutants mobility using plants. Both practices are applicable to organic pollutants and heavy metals and apply over the long term. Thanks to our expertise and our partnership with the company Microhumus (www.microhumus.fr), the specialised European company with…

Mycoremediation

Mycoremediation of polluted soils and earth involves taking advantage of the ability of certain strains of lignicolous fungi (wood-degrading fungi) to produce substances (enzymes) to degrade substrates with a chemical structure similar to many organic pollutants. Enzymes produced by the mycelium (the mushroom-producing organism) therefore have the potential to destroy a large spectrum of pollutants.…

Brownfield and sites valorisation and development

The restoration of degraded soils, the revegetation of sites and phytomanagement fit many applications: industrial and urban brownfields for further development; Redevelopment of quarries, when stopping the activity or expanding the production area; Real estate developments including green spaces or urban agriculture; Agricultural lands to be diagnosed and improved; Marginal sites to be valorised, for…

Ponds and constructed wetlands

Ponds and constructed wetlands can be designed purposely for water treatment. These ecotechnologies are bioinspired by the ability of natural wetlands to treat various pollutions, via interactions with substrate, plants and especially the associated microorganisms (phytoremediation). Constructed wetlands are artificial wetlands with water flowing over a bottom made of soil substrate for plant growth (macrophytes).…

FILTRAN® combined vegetated filters

Developed by Cebedeau (www.cebedeau.be), the FILTRAN® process is a compact vegetated filter for the treatment of organic matter and optimised for the treatment of total nitrogen through nitrification and denitrification. The process combines in one step the advantages of unsaturated vertical filters and saturated horizontal filters. Its additional advantages are: A smaller footprint than conventional…

Phytotreatment and evapotranspiration beds

Phytotreatment processes, inspired by wet meadows and riparian areas, are based on water flowing through plants and / or soil of a dedicated facility. Water treatment results from stem filtration and plant-soil-microorganism interactions at root level and must be completed before infiltration into the subsoil. We can apply phytotreatment in combination with our other ecotechnologies,…
