The 2 years project Work Plan is divided in 9 Work Packages (WP) to achieve the Scientific and Technical objectives. The work plan has been structured with 23 specific, measurable and time-bound Deliverables assigned to Tasks in order to achieve 2 verifiable Milestones thanks to an appropriate allocation of effort in the form of 127 Person-Months (PM). The RTD work delivered by INSPIRALIA, WELIENCE and ACCIONA has been split in 6 WP, each covering a different expertise area. WP7 (DEMO) will enable LEPRIEURE, AGRIFUTUR and UGN absorb our GRABGAS technology into a marketable low cost and efficient biological VOC control solution. To ensure the rest of European SME end users have access to GRABGAS, WP8 covers all Exploitation and Dissemination of results, while WP9 ensures an efficient coordination and management of the project by LEPRIEURE. In rhizodegradation, plants, soil and microorganism cooperate together. Rhizodegradation is the breakdown of organic contaminants in the soil by microbes, which is enhanced by the presence of plant roots.A variety of contaminant-degrading enzymes can be found in plants, fungi, endophytic bacteria (bacteria living inside the body of plants), root-colonising bacteria and soil bacteria. Why is rhizodegradation the solution for low and variable concentrations of VOC mixtures? GRABGAS uses rhizodegradation to solve the limited efficiency of biofilters to treat variable concentrations of mixtures of VOCs. Rhizodegradation (also called plant-assisted bioremediation) has the potential for remediating a variety of hazardous chemicals: there are laboratory and field-study examples proving that rhizodegradation (soil bacteria + plant roots) can be used to better degrade VOCs.

Objectives to achieve and obstacles to overcome

  • Developing effective catalytic surface that efficiently oxidises VOCs into non-toxic by-product concentrations by transforming visible sunlight to chemical energy
  • Finding an appropriate growing media composition that allows plant growth on roofs and a rhizodegrading capacity of VOC
  • Understand the physical/chemical/biological phenomena that govern rhizodegradation, gas flow and moisture transport through the substrate
