Vertical Green Biobed for the efficient degradation of pesticides

Due to increasingly stringent legislations biobeds are gaining popularity. They allow to naturally eliminate pesticide effluents. Common biobeds show significant weaknesses: they get easily waterlogged and require very large surfaces. Such problems are solved by the vertical green biobed developed by the HEPIA - Soil and Substrate Laboratory. It is more cost effective and as fully vegetalized is much more appealing to the eyes and requires small land use.More and more farmers wine producers greenhouses users golf course owners and managers of greened land in general are facing environmental requirements to treat pesticides effluents (generated by the preparation of phytosanitary treatments and the washing of soil pulverizers) and avoid their release in natural and environmentally sensitive surface water.The Swiss agronomical research laboratory managed to solve the common biobeds weaknesses and as a result developed a vertical green biobed for the efficient and ecological degradation of pesticide effluents from farms golf courses municipalities greenhouses and so on. While these vertical biobeds look like regular walls covered entirely by plants and as such bring an aesthetic touch to the landscape they simultaneously perform efficient pesticide effluent treatment. An automated collection storage and dripping system allows for the continuous degradation of large quantities of effluents typically 6 m3/m2/ year compared to 0.6 m3/m2/ year for existing horizontal systems.
