I seen the pics, was wondering what that was!, I just say farts cos it s funner and associates to an image i posted somewhere else, it is actually quite amazing that any organic breaks down as such. Also thanks for clearing up, was wondering about stages. Also I think the problem with figures is that it may just be a promo out here, may deflate with popularity, and prolly arnt the same in other places.
It is also very interesting on the profit you get on a biofuel system, without any biofuel at all, unfortunately even going on a ledge i can only rake up 10% of the cost of the old system.
I found a way to cut out the middle men and most of the expense however i doubt it is strictly legal, so i wont bother to elaborate or design.
But I hope you guys are able to squeeze a buck out of this.
It seems this is popular topic specifically with the revolutions coming, I have seen links as well where they are trying to use it for septic systems.
Check out the "Bloom Box" or microbial fuel cell, apparently google dropped like 50million in to some of these.
I actually got in to this when i wanted to see the bio value of compost materials , there is alot of food wasted at my place and it makes me very sad. But since im so small scale a little cell to power a small light bulb may be the way i should go(an just forget the grid). It will be interesting to see in 10 years if we all actually have home power plants sitting next to the A/C unit.
To make it pay you need to go and talk to water companies
, get the fatbergs and use that. Some (in the uk) will give you money to look into it, they spend a fortune clearing fat waste from sewers and it makes a great bio fuel for cars or can be broken down in a digester (areal pain and better to break down into fuel first).
I have had a small petrol generator running from the gas on the septic tank, but I had problems with the feed in.
Methane plants are getting popular here in Scotland at the moment, especially the combined heat and energy ones. I would keep at it, ignore the rubbish on american bio fuel sites regarding titration numbers and not bothering with solid fats, The money is in the solid fat waste not waste veg oil. Everybody and his dog is after good waste veg oil and the price has jumped. NO ONE wants the solid fats but they can be made into biofuel easy enough if you do the research, alot of places will actually pay to give you this stuff, Look into non chemical and chemical means to extract the fuel. Many times sulphuric acid is used as a drying agent in some parts of the process, this is expensive and not needed. I would use saturated salt solution for any dehydration before the final wash stages.
After that I would go the clacium sulphate/magnesium sulphate route then use an acid if I had too.
To get a good idea how wet your fuel is you dont have to mess about doing this test or that test, simples to use copper sulphate (root killer over there) and heat it gently on a tray until a very very pale blue, this is the dehydrated form,the normal form is a deep blue.
Put a small amount of the copper sulphate powder into the fuel and see if it clumps and goes blue, if so you have alot of water. When the fuel is dry you wont get clumping or much of a colour change, you can dry fuel with copper sulphate then filter and dry the sulphate again, but I would use the other drying agents instead and keep the copper sulphate for a quick water test.
Also keep the glycerine and distill using the heat from the exhaust manifold, distilled glycerine has a pretty good value or can be chucked in the bio digester without bothering to distill.
If its organic (including carbon particles) sling it in the digester. I couldnt get ammonia before we had a company registered here so I used maggots to produce the ammonia and then distilled the liquid (mostly ammonia anyway)
