We will layer up with plenty of browns and greens and bacterial activators, leaving a 'nest' in the middle for a few buckets of the dried toilet material. We'll then Close it all up, ensure that thermophillic composting is taking place and that the inside of the pile is nice and hot for a while, then start turning.

Temperature, oxygen and carbonmonoxide are measured directly and can be compared with other gas analisers. All the rest is calculated using those three, so is the efficiency. As Jura Rafal mentions, the formula to calculate that are slightly different from country to country depending on what the rules say for that specific country. So difference between mine and say, Matt Walker's analizer's efficiency is about 8%. Regrettably, making efficiency numbers a very unreliable number to go for.

I'd like to learn more about the instruments used and guidelines to run those tests so I can see the performance and share my findings.

Many thanks for any answers, Esbjorn

A company in Wales has been running a pilot plant that will recycle the materials on a small as well as a large scale. If it has no problems in real life, it could be the answer:

I just cannot recall the full story, but if that happens, we may not be able to get them anyway.
