"Complex" Pyridine [not simple PDADMAC.] Yael Mishael – Clay Polymer Sorbents for the Removal of Organic Micro-Pollutants (TTM:2876)– Prof. Mishael developed a patented clay based ‘pyridine’ composite to remove organic pollutants with a higher efficiency then activated carbon. The composite is cheap to produce yet highly effective in removing drugs, herbicides and pesticides. Patent Position: Yissum Online: Below thoughts were edited and approved by Yael Mishael: The complex pyridine based polymer is ‘designed’ for catching micro pollutants @ ng/Liter concentrations (single molecule - pharmaceuticals, herbicide, pesticide), but there are no regulations in place for treatment of micropollutants from waste water.  So there is no incentive for companies/municipalities to add expensive capex to treat this wastewater (capex for pumps, filtration columns etc – irrespective of adsorption resin). There is not really a need for filtering freshwater (tap water) through a complex resin since freshwater is not tested for micro pollutants and is not likely to have this and again there is no regulation for this.   On the other hand the simple ‘PDADMAC’ polymer can be used for filtering any dissolvable organic matter (humeric/muddy), and can be used for clearing up opaque fresh water prior to drinking or treated wastwater. So the results are clearly visible and can be used in municipalities and private home filtration systems, and it was found to be more efficient and more cost effective in purifying organic matter than granulated activated carbon.

Members of CIBIO Research Institute, led by Professor Maria Angeles Marcos Garcia, head of the Associated Unit to CSIC, have developed a method to raise the dipterans predator Sphaerophoria rueppellii. This insect is known for its efficiency and high specificity predatory sirphid being more suitable as biological control agent against agricultural pests from aphids in a Mediterranean climate crops. The use of this natural enemy for biological control of pests will reduce pesticide use in both agricultural crops and in urban gardens. Have been optimized environmental conditions for breeding, such as diet (both immature and adult stages) to ensure a higher reproductive potential and higher rates of survival. The group is looking for companies interested in acquiring the technology for commercial exploitation. Innovative aspects 1- The only species of industrially produced sirphid (Episyphus balteatus) does not effectively control aphid pests in Mediterranean cultures, this is why the selection of another species of sirphid to act as a viable alternative in the field Mediterranean was needed. The novelty of this specie is that and in most cases of biological control, using species that are commercially available, or not part of the fauna, in this case, we have managed to breed the species in field trials, proved to have the greatest potential for control. 2- This is the first time that this predator specie is bred in the laboratory and maintain continuously during successive generations breeding in significant amounts from individuals. 3- Due to the invention has been developed by a consolidated research group, it will be applied a Quality Control (under the rules of the International Organisation for Biological and Integrated Control), to ensure the viability and product quality
