Howdy, this is a project to produce sugar from cellulose.

The idea is that since in many animals(including cows) cellulose digestion occurs via bacteria, that one could create an artificial stomach, a habitable environment for these bacteria and feed them large amounts of plant vegetation.

The bacteria would hopefully digest the plant vegetation, converting to usable sugars, which would then, after the plant was fully digested by the bateria, be heated to the point where the bacteria would die, leaving a large amount of sugar.

The sugar could be eaten along with the dead bateria which would be like Yogert, and I believe it would be non-toxic, because if we can eat cooked cow guts(which contain this bateria), then we can eat this stuff.

Basically, using cow bacteria and an artificial environment to convert the endless food supply around us to food.

The energy requirements would be nominal in comparisons to the gain.

This essentially, is the fusion of the food world.

Those who have an endless food supply, will be in the position to sell it to anyone else for whatever they want.

What is the maximum recovery rate for cellulosic waste?

Unread postby nth » Mon 24 Jul 2006, 15:33:13

I heard if we need to, we can recover 40%. There were no published paper to back up this claim. Makes me think if anyone has any ideas? Since yours can be just as accurate.

$this->bbcode_second_pass_quote('pstarr', 'w')hat waste are you talking about?

Are you referring to loose material from lumber or paper mills, the crop residue from agricultural, the scraps from commericial printing, the junk from residential recycling?

Or are you talking about energy return from the conversion of that waste to liquid fuel?


I am talking about waste. things that are thrown away: plastics, paper, industrial wastes like what you mention, sewage, etc...

What I meant by recovery is the ability to collect the waste at central sites around the country. So just talking about US, all recycle paper collected will be waste recovered. All garbage are not recovered, but can be easily recovered. So the maximum recovery rate will include garbage and waste treatment plants including sewage.

I don't want to talk about the efficiency of converting this waste into usable energy. I want to narrow my question to simply how much waste we can recover.

Very difficult to tell and depending on the quality and composition of the lignocellulose contained in the biomass.

If you're talking about say a typical residue like bagasse, then you have 41% cellulose, 24% hemicellulose, 18% lignin and 2% ash.

If you were to take the enzymatic conversion route, and release Trichoderma reesei KDG-3 on this bagasse, then you would obtain a total amount of fermentable sugars of 200 gram per liter after 50 hours of saccharification. So your conversion ratio would be 20%, after which you ferment this pure sugar (95% efficiency), so you end up with say 18%.

The residues from this process can be burned as solid biomass. Don't forget that lignocellulosic biomass has to be pretreated. This takes energy too.

Using better enzymes and a biomass feedstock with less nasty lignin, would considerably increase that efficiency, and indeed several processes using particular lignocellulosic feedstocks achieve 40%.

Sorry, lorenzo. This is not what I was trying to ask.
My bad.

Lets just say Cellulose ethanol ok. And since you are a drunk i guess you would know about there dreams.

VampeyGirl - fancy webpages can't fuel a car.

Demos and samples are worthless.

Like all other technology that's predicted or theoretical, I'll believe it when I see it.

Why can't you make your own arguments instead of tossing links at people like holy water in a horror movie? Take the time to distill some substance from your sources and present it, if you're able, instead of just blindly swallowing the pitches of companies that are aimed at duping investors. It you took the time to think a little more deeply, you might realize it's all a bunch of smoke and mirrors.

Vamprey Girl is an interesting poster - I'll give her that.

It's like you're sitting there minding your own business, then WHAM!
