3 Technology How? keypriciple : exploitation of heat effects of electromagnetic energy for eradicating all pests by attaining their Lethal Temperatures (LT). Why? Successfulresponsetotheincreasing demandforpestcontrolmethods ensuring: Efficacy Safety Environmental sustainability EMitech s technology in agro-food is anoninvasivemethod using microwaves for disinfestation anddrying of food products represents an innovativeandecofriendly solution replacing chemical products andfumigants

4 Biological infestations of agro-food products Themaincauseoflosses inthe PostHarvest phaseandinstorage is represented by Biological Infestations which begin onfield. Biological Infestationscan: Significantly depreciate alotofproducts in avery shorttime MEDSPRING 25th26thFebruary 2015,Berlin Post-harvest Losses (PHL) Losses From10to50%(intropical areas) 25%whole worldproduction About1/4ofwhatisproducedneverreachestheconsumerforwhichitwasgrownandefforts andmoneyneededtoproducehavebeenlost MEDSPRING 25th26thFebruary 2015,Berlin

5 Conventional disinfestation methods Conditioningofsilosandwarehouses Controlled atmosphere Extremetemperatures Fumigation Disadvantages: Highcosts andlongtreatmenttimes Handling of dangerous chemicals Persistence infood of toxic residues Pollution Conventional disinfestation methods

6 Conventional disinfestation methods MISYA method MiSyA is aphysical method that canbe used to disinfest all products of vegetable origin infested by pests: Cereals (rice included) Legumes (beans,chickpeas,lentils,etc.) Seeds like pinenuts Dryfruits Thankstotheheateffectsderivingfromtheinteractionbetweenelectromagnetic energyandpolarmolecules(inparticularwater),itispossibletoachieve lethalityofpestsbyoverheating immediatelywhentemperatureachievestheir LethalTemperature(LT). Mortalitytests,conductedovertheyears,onvariousspeciesofpests,inalllife stages(eggs,pupae,larvae,adults)showedthatltsrangefrom55to60 C.

17 Advantages Full efficacy: 100% mortality rates on pests in all life stages (eggs, larvae, pupae and adults). No significant change in food quality (physical and nutritional characteristics) Absence of polluting effects harmful to operators and the environment No toxic residues in the end products Energy saving Advantages All systems are upgradeable. They can fit the smallholder farmers needs and even larger agri-industries (possibility to be integrated with existing plants) Systems in ISO-STD Containers are thought to facilitate international and intercontinental transport. They are fully equipped and can be moved directly in production places to provide an efficient disinfestation service to farmers and producers Complete automation Rapid and easy maintenance Easy cleaning and sanitizing
