The Johnson-Su Composting Bioreactor

Listen to co-creator of the Johnson-Su Composting Bioreactor, Dr David Johnson, discuss the construction and filling of the unit and answer questions at the Carbon Link Soil Carbon Trading Roadshow, December 2016.

I noted at the 6:46 mark in this video that Dr Johnson says this can reach a thermophilic phase that will meet USDA requirements if built right. I understand that microbial activity is what heats up a static pile, so my question is if anyone knows what is the ratio of high nitrogen, greens and browns in the pile does the pile compromise of to get to the temperatures he noted?

Could Johnson-Su be scaled up to use as a municipal form of composting organic matter? I am interested in how this could be utilized by a town or community for home composting pick up and yard waste at a large scale. The product is then recycled to area farms and gardeners. Any feedback on this would be appreciated!
