The method is designed to yield an optimum rate of biodegradation by adjusting the humidity, aeration and temperature of the composting vessel. The method applies to the following materials: • Natural and/or synthetic polymers and copolymers, and mixtures of these; • Plastic materials that contain additives such as plasticizers or colorants; • Water--soluble polymers; • Materials that, under the test conditions, do not inhibit the activity of micro--organisms present in the inoculum. Echo Instruments respirometer system is designed to yield the optimum conditions for biodegradation of a plastic material in compost by precise control: aeration flow, humidity, pressure and temperature in the composting vessel. It also aims to determine the ultimate biodegradability of the test material by using a small--scale reactors with multi--channel gas sampler. The degradation rate is measured by determining the mass of the evolved carbon dioxide using infrared dual channel optical sensor. Advantages of automatic measurements in comparison to gravimetric method Traditional gravimetric technique can be time consuming. The main advantage of an automatic on--line measurement is continuous monitoring of parameters in the reaction vessel. Working conditions are continuously checked. The main priority is to check the tightness of the system, which significantly decrease probable troubleshooting.

Modular System ECHO Respirometry System is fully modular and designed for fast modification according to research needs. -- Easy expansion of units from 6, 12, 24 or more channels -- Upgrade kit for liquid samples -- Additional Sensor Upgrade according to customer requirements (CH4, H2, VOC…) beside the basic sensors CO2 and O2 Automatic Humidification One of the main advantages of ECHO Respirometer System is that the samples are automatically adequately and constantly humidified. The system provides the constant humidification of samples by returning the condensate water into reaction vessel. Because of less water refilling need, the necessary manipulation of samples is drastically reduced. Sensor Technology In--build multi sensor technology enables customer to easily add sensors to the respirometry system. Basic sensors: Optional sensors: • humidity sensor optical NIR: CH4 • temperature sensor electrochemical gas sensors • pressure sensor PID: VOC • optical NIR dual beam: CO2 sensor • electrochemical or paramagnetic O2 sensor UPCOMING in a year 2016: marine environment respirometer We are developing a new marine system for measurement of biodegradability of different waste for example plastic particles, organic components in marine environment.
