SAIDA UMS INC./SAIDA FDS INC.| MODA(Microbial Oxidative Degradation Analyzer)

MODA is an apparatus of biodegradation test in laboratories according to ISO 14855-2 which specifies test procedure of biodegradability of plastic under compost condition.

The Microbial Oxidative Degradation Analyzer (MODA) is a laboratory scale apparatus designed to evaluate the aerobic biodegradability of plastic and other materials under controlled composting conditions by analysis of evolved carbon dioxide. It is easy to operate and its small footprint makes it ideal for rapid and accurate evaluations of biodegradability on the laboratory scale.

(W24×D28×H47 inches).
Precise temperature control (+/-2℃).
Four reaction columns with independent temperature control.
Easy to use.
Complying with mostly ISO standard.

MODA-6 is a newly developed apparatus completely satisfying ISO 14855-2 requirements.
Six reaction columns are installed in an environmental chamber keeping the temperature condition same always.

Features:

Dimensions;W900mm×D450mm×H1700mm
(W35.4×D17.7×H66.9 inches).
Precise temperature control(+/-1℃).
Six reaction columns in the condition of same temperature.
Aerobic biodegradability of plastic under compost condition.
Easy to use.
Complying with ISO 14855-2.

1. ISO14855

Managing plastics waste is becoming serious issue among the world.
Biodegradable plastics that is to be resolved by microorganisms in compost and soil bear important role for reducing environmental negative impact.
ISO14855-2 is the method to measure and determine the degree of biodegradability by "Gravimetric Measurement of the Amount of Carbon Dioxide evolved" from plastic material in compost.
Compared with the earlier method by ISO14855-1 which uses continuous infrared analysis, gas chromatography or titration, this new method can do testing with compacter and smaller equipment.
Test result is more accurate, more certain as that uses gravimetric measurement.
Saida has been involved to develop test apparatus MODA from the start of the development of the method with governmental research centers, universities and industrial organization. Based on the expertise we had in the past, we supply the best test service on biodegradability of plastics in the world.

2. Test Procedure

The test material is mixed in the compost, and it is kept about 58 degree C for 45 days at the shortest. Taking out the compost once a week from the reactor to give them stirring at the same time moisture adjustment is done. In total 6 reaction column are used. 2 for test material, 2 for reference material and remaining 2 are for blank.
CO₂ measurement is done by measuring the weight of absorption columns of blank, reference and test material. The biodegradation rate is obtained by comparing weight of CO₂ obtained from the test and theoretical weight of CO₂ obtained from the molecular formula of the test material.

3. Glossary

Test report titled as "Biodegradability Evaluation Test Report" is to be issued after finishing the test. The test report contains followings.

Samples are degraded in active compost through which air is blown under controlled conditions. The evolved ammonia and water are removed and the carbon dioxide absorbed in soda lime(sodium hydroxide). Carbon dioxide evolution is measured by weight increase of the soda lime.
For MODA-4, that has 4 reaction columns, one reaction column has compost only called as "blank", which determines carbon dioxide evolved from compost only. Remaining 3 reaction columns have sample materials mixed with compost, which determine carbon dioxide evolved from compost and sample materials.
The reaction columns can be controlled desired temperature. If following ISO 14855-2, temperature is controlled at 58℃ typically.
Samples are weighed periodically during the test period.
