ReDish (Part 3) : Next Step: 20% to 50% Ratio

20 to 50. This is the next challenge that Green Life 21 faces. It's the ratio of recycled ceramics and virgin material when manufacturing ReDish. The current ratio is 20:80, 20 the recycled part, and it's shooting for 50%.
Gifu Prefectural Ceramics Research Institute, a prefecture funded research organization and a member of Green Life 21, has been conducting a research project to achieve this ratio since 2008. The project is funded by the Ministry of Economy, Trade and Industry.
"We have 3 goals to achieve. One is the increase of the blend ratio. 20% to 50%. Second, decrease the burning temperature of an oven by 100C. Third, increase in flexural strength by x1.5." Mr. Kenji Tateishi, a person in charge of the research at Gifu Prefectural Ceramics Research Institute, said. "If these 3 elements can successfully be achieved, there will be a significant contribution to the emission of CO2."
At this stage, a team of Mr. Tateishi successfully produced samples, which qualify 3 criteria in a small lot by controlling a ratio of additives.
"But when samples are mass produced in a factory scale some of them cracks. A tuning of the material, as well as the factory's production process need to be adjusted."
The quest of ReDish continues.
