Whatwhatwhat.. -Mimic the natural process? Mimic||? It IS! the natural process, streamlined! Our digesters were constructed mid-20th century of cement. There has been some cracking of the cement. However, specialized contractors are engaged periodically to strip/prep/line (application of acid resistant coating) interior surfaces. So cracking hasn't been a significant problem. I think the cement tank facility is probably the best approach since the cement is an insulator, providing a buffering from outside temp. fluctuations. The cement tank is probably cheaper than the steel. Keep in mind, a huge steel tank will have seams (problem potential welds). Digesters should be taken out of service at certain intervals anyway for inspection/maintenance etc.
The methane produced from our digesters provided energy for their operation, plus a huge methane surplus.. Yield is roughly about 1 part methane to three parts CO2. The CO2 can be used for an algae operation. I like the term biogas, rather than focusing exclusively on methane, since the CO2, in my opinion, is nearly as valuable insofar as use for algae, which can go either way, high-lipid, or high cellulose. And in either case, the leftover "waste" sludges are themselves most useful for solid fuels manufacture (pellets, biocoal, biochar etc.).
Looking for information as we want to have a biogas plant as we have a lot of waste from chicken manure and vegetables waste of 80 000kg in year
get in touch with us:) chicken litter is one oh the best biogas substrate; biuro@lighthief.com
Do you do financing for such projects?

What happened to Co2 and hydrogen sulfied then
