MODA apparatus

MODA-apparatus is shown in Fig. 1. The principle of this method is to measure the increasing weight of the absorption colunrn charged with soda lime due to evolved carbon dioxide. 

Under the ring testing conducted by BPS, experiments were performed by using three MODA apparatuses. The four reactors of each apparatus were set with blank, reference sample, and two test specimens, respectively. The components added to each reactor are reported in Table 3. 

The authors would like to thank Saida Ironworks Co., LTD. for supplying the MODA-apparatus. The experiments were carried out in cooperation with the technology committee members in BPS. We also thank Daicel Chemical Industries, LTD. Showa High Polymer Co., LTD. and Mitsui Chemicals, INC. for supplying the plastics. We wish to thank Dr. K. Ohshima (BPS) for his scientific advice and Prof. M. Kimura (Nagoya University) for his soil biology advice.
