Hi Newt, the temperature required is about 450C.

The programme is very small (only 160 units), but these are part of a larger programme with a range of biogas plant sizes (total of 3000 units installed). The digester is fabricated, so it forms the right shape when inflated by slurry and biogas.

There is a large number of publications on biogas from groups such as SNV. Most of the successful programmes were based on masonry plants, such as fixed dome systems.

David Fulford
500 plants in three years is seen as a small programme for domestic biogas. It is not clear how it can be patented, as flexible plastic biogas plants have been used for at least 20 years. Plastic biogas plants can be made very quickly. Practically, they have a short life-time, unless they are looked...
Flexi Biogas BG5 -
David Fulford
The use of flexible biogas plants is very popular in Kenya and other places in East Africa. They are much cheaper than masonry plants, but have shorter lifetimes. Flexible bag plants were first used in Vietnam, but masonry plants became more popular, as they did last much longer. The vary large prog...

The plant seems to be very effective, using the particular feed material that is easily available (prickly pear - nopal).

The Nopalimex plant wortks well on the site for which it was made. There are minimal transport costs and economies of scale.

David Fulford
Nopalimex is a biogas digester that processes prickly pears into biomethane. The pears are ground up into a soup, mixed with manure and fermented in a digester. The biogas generated is then cooled to dewater it. The gas is also used in the factory for making corn and cactus chips, as well as in a ge...

Regarding IP: Converting banana fibers to absorbent fluff and using it in napkins is known in the art and practiced in other operations (e.g. SHE's go! pads).

Michael Moscherosch
Considering the sparsity of bathroom facilities (or other locations to change the pads outside the home) in India, I would recommend to design pads that can be used at least for 12 hours. The user can put on a pad in the morning and change it at night, both in the privacy of her home.

How and why does Saathi sterilize the pads? Sanitary napkins are normally not sterile, they just have to meet the microbiological requirements of the governing body (expressed as a maximum bioburden, measured in cfu)
Banza Toilet -
Michael Moscherosch
Using banana fibers as absorbent is a very good idea. Converting agro-waste (i.e. banana plant trunks) into sellable fibers creates jobs and additional income for banana farmers. Banana fibers can be converted into fluff pulp that can deliver the absorbency and properties needed in napkins.
Banza Toilet -
Michael Moscherosch
我question the capability to produce 1,000,000 pads with Saathi's current setup. If my information is correct, I estimate their daily production to be less than 1,000 pads. It would take them 3 years to make 1,000,000 pads. Unless they have a production of about 4,000 pads per day they would not mee...
