hi Alex an all

what about yeast for bread? it is easy to buy in rural areas and is cheap. one kg of yeast fro digester less than 10m3 liquid volume. In some places in bolivia, in cold climate, they are using this technique, and reduce the sart up of the digester from trhee months to two months. So for warm temperature digester can be a few weeks to start upo de digester if you add yeast at the begining.

keep in touch

HI All, 

We have been doing our systems start (for small household scale digesters) with the paunch waste from slaughterhouses, adding 50-100 liters of the waste along with manure and water as an initial charge.  Transporting this waste (wet, heavy, and a bit nasty) is a bit of a pain.  My technicians keeping hinting at better incolculant solutions, and I would like to see if there is anyone out there making really effective inoculates (or knows how to make them) that are dry, simple to apply, but really effective in starting a digester.  Efficient and fast start-up is a really crucial aspect of technology adoptions, and using effluent from functioning digesters or the paunch waste has produced the best results for us as far as start-up rates.  We have seen a brand of tablets for septic tanks, but we have not found them to improve start-up times as compared with straight manure.  Thanks in advance.  

Saludos,

A
