Bio-digester supplies energy to 3000 farms

January 5, 2016

The principle of action of a cow's digestive system served as a model to create a container that receives organic waste, mostly livestock manure, where it is mixed with millions of bacteria to obtain natural gas consisting mostly of methane, called biogas, as well as a high-quality bio-fertilizer.

The biodigester, commercially called Biobolsa, transform the waste in a container made of a high-density geomembrane where polyethylene components and bacteria generate gas that is used as fuel for stoves or heaters, and even in the form of electricity.

Alex Eaton, one of the creators, said in an interview that technologies such as the anaerobic Biobolsa have been used for decades in industrialized farms, and researchers now seek to bring its benefits to small and medium producers, which generate 99 percent of the country's food and 80 percent globally.

"We have visited families who have small farms for subsistence, or less than a hundred dairy cows. Those families are without access to credit or financing. They also make up the social fabric of rural areas, as the caretakers of watersheds, land and soil. This is a way of empowering them in climate change, soil management, food safety, water pollution and more."

Eaton explains that his technology consists of a bag of 15 meters, which can contain up to 40,000 liters of liquid and treat one ton waste per day.

The researchers have adapted it to specific needs and created smaller bio-bags of two by two meters, working with 20 kilos of manure. "The system is modular and can interface, it also is deployable and adjustable. On average, the return on investment is seen in a year and a half, and if you consider that the material used for the Biobolsa lasts longer than 20 years, there is much room for profit," he says.

He adds that there are many small producers who are not aware that there are economic and environmental options to leverage what usually is waste—in this case, that manure can generate revenue.

Biobolsa technological transfer includes training and implementation, as well as monitoring its operation and efficiency.

The Mexican anaerobic technology has had support from various foundations and government institutions for its development and implementation, which have provided partial subsidies to stakeholders. "Today we manage a credit fund with zero rate for small producers to participate," says the ecologist.

Biobolsa has received several international awards, both scientific as for social entrepreneurship, among others, the Network Business in Development (BiD Network), of Holland, which gave an award for 10,000 euros which served to give a major boost to the company.

"We have improved the process and have a number of engines for generating electricity. We already have a contract to produce light for the electrical network of the Federal Electricity Commission in Cuernavaca (south of Mexico City), through interconnection with biodigesters to produce five, 10 or 15 kilowatts.

"We want to impact four million homes that, we estimate, could use Biobolsa today in Mexico" says Eaton.

It is about time. The ethanol plant I designed for a large Idaho dairy had three of these to power the ethanol plant and the rest of the dairy, and could sell power to the utility.

That was in 1980-81.

Why isn't every farm in the country utilizing these vile digesters for not only their own power needs what possibly a few of their neighbors? It would certainly make it better for the farm's bottom-line if they could sell electricity to a few neighbors as well as not having to purchase it from the local utility.

Enviro, it is more important than that, even. It means we capture greenhouse gases, and we capture and reuse the Nitrogen. By doing so, we end the nitrogen pollution of our water and the volatile solids from manure.

It does much more than converting waste to fuel.

Ira gave me a one for the comment regarding my alternative energy system, But he has the thesis based on it, because I sent it to him. Unable to understand simple English, he failed to even read it.

It shows how using different alternative processes in integration we can achieve synergy. It also shows how to clean up our act.

I give to you the one because you make silly remarks and slogans. But yeah, I read the "thesis" that peoples who really write those things tell me is high schoolish and immature. They also tell me it is doesn't have all the things a real Master Thesis is supposed to have in him.

You are the one who then claimed you wrote that way on purpose because you were writing it for goobers to understand. But professors don't appreciate being called goobers and would not care much for you writing out your "thesis" like that. So I got my doubts about him yeah.

It shows how using different alternative processes in integration we can achieve synergy. It also shows how to clean up our act.


It also shows that glam-Skippy writes "thesis" for goobers not professors.

Show me your analysis of anaerobic digestion and how to integrate it into dairy and grid operations. Mine was done in 1980 to 1981.

The illustration implies a plug-flow type, but Continuously-Stirred Tank Reactors have higher outputs. They have been using high-temperature Mesophilic bacteria, operating at about 100 degrees F, near the Thermophilic range.

-And you did it with no formal engg education and no engg-level experience. And the copy you sent ira was missing the last 70 pages or so, which we can only conclude contained the critique by your prof or profs.

Why did you hide it?

This 'paper' was apparently sufficient however for you to receive an MS in 'life experiences' which for some reason you insist on referring to as 'environmental management'.

Ira and/or stumpy showed that that degree was issued by another department entirely, and required an undergrad degree and coursework.

So congratulations. You earned a worthless piece of paper, much like the handshake and the free dinner you got as airman/solder tech of a month, which is also fooling no one here.

It only reinforces the conclusion that you are a liar, a cheat, and a fraud.

Thanks again - the people here do need to know what you are and what you are capable of.

I designed an integrated plant for the production of many outputs, yes. No, I did not do the licensed stuff, but left that to the hired hands. I used off-the-shelf systems and integrated them. Do you folk know how things work?

You silly folk have to stoop to your semantic games,since you cannot debate the issue of anaerobic digestion. By now you will have double-checked me on wiki and other places, or you would be throwing it back at me.

I did not have to look anything up, and when you folk do it, you do not understand what you read, and get poor conceptualization and miss the implications completely.

-He didnt need to reference ANYTHING during the course of his 'work'.

Those of us in the 'business' know that real engrs are constantly checking tables, govt regs, zoning ordinances, industry standards, etc. Why? Because they HAVE to.

This is why for instance he had no idea that CFR governed opacity standards for stack emissions.

For 40 years.

George youre telling us you wrote a cartoon. I popsci article. Youre telling us that the real work was done by real engrs who undoubtedly had to reconfigure and redesign your cartoon from scratch.

George thinks that 'add tank' and 'connect with pipe' is the way engrs work. No, selecting and sizing those tanks and pipes are what engrs do.

And youve proven time and again that you are obviously not qualified or capable of doing that sort of thing.

And this is also why george says he hates HR people. Theyre trained to recognize this sort of bullshit. HR depts were established expressly because lying, cheating psychopaths exist and they were costing companies billions.

Can you imagine what an HR screener would think of george referring to real engineers as 'hired hands'???

This can also explain why he was a 'consultant' for the last 10 years of his 'career'.

No, I did not do the licensed stuff, but left that to the hired hands.


The "licensed stuff" involves pretty much all the actual engineering.

You aren't legally allowed to approve designs and specifications, hire or act as a manager or supervisor to engineers and builders, or work in a consulting position to actual engineers, or call yourself an engineer or have a job title with the word "engineer" anywhere in it without an actual engineering license - which you do not have.

That means those "hired hands" who did the licensed stuff were either an actual engineering firm commissioned by a client you were working with - in which case you were simply providing them with the concept drawings and client side specifications - or they were actually your superiors in your company and you were their hired hand who was simply tasked at drawing and calculating stuff for their designs.

You're taking an astonishing amount of credit for what you've never actually done.

Besides, the whole story doesn't pass the straight face test.

Gkam, you were in that job for what, six months again? A year? As if they would just let some job-hopping Johhny-come-lately design an entire ethanol plant right off the bat by himself without any of the legally mandated qualifications, or any proper degree in the field.

You just walk past the HR department by making buddies with the CEO, and off you go designing chemical processing plants like a pro with little to no experience on the job, with a degree in "environmental management" in your back pocket to see you through it.

Do you honestly think we're all completely stupid?

It was a thesis. But I got paid for it from the Dairy who requested the report and study and system design. I'll send it to you.

And from your posts yeah you are stupid to think your wiki-enabled searches take you to the truth. It is funny to see how foreigners assume how things are done here then attack folk based on that ignorance.

I did not design the ethanol plant, I found one and integrated it into a system with other alternative energy elements. The anaerobic digesters were plug-flow based on the ones at Mason Dixon Farms which were the only really well-operating ones in the nation at the time. I use three in parallel, 17-day retention time, and have a stabilized output with still traces of cellulosic material as substrates for the beneficial bacteria which goes back on the field, mixed in with the irrigation. It is nutrient-stabilized, eliminating the need for adding supplemental Nitrogen and Phosphorus.

Do I have to discuss mesophilic versus thermophilic, the substitution for Distiller's Grains for the imported cotton seed, (ironically bought from my hometown of Chowchilla CA), the increase in butterfat content, and the other benefits of the system? The fact it made more electricity than the entire Idaho dairy used?

You doubt it because you invented a little concept and believed it.

I think you folk are unaware of how things are really done in Silicon Valley and other places in California which have special projects. People are hired for their skills, not their paperwork for HR. I never got a job using HR. Even the PG&E Energy Services Engineer job by-passed HR, so they could interview us correctly. Our group was hired in at the level most folk retired at the company - we were all already accomplished in our field, which is why we were hired.

No wonder - you folk are still wallowing in 20th Century thought.

It's too late to backpedal now. You've been caught lying - again - and still you're using the age old bluff of throwing in irrelevant details as a smokescreen.

People are hired for their skills, not their paperwork for HR.

Even the PG&E Energy Services Engineer job by-passed HR, so they could interview us correctly.


Which would be illegal in california, because you can't be an "Energy Services Engineer" or any "engineer" without an engineering license in California. You're either lying your ass out, or you're claiming that PG&E were breaking the law.

Once again - ignorance. That was my company title. At the time PG&E was the largest non-governmental power company on Earth. We were in the process of putting together the most comprehensive set of conservation and energy-efficiency teams in the nation. I was sent to organize, train, include in operations, university personnel from technical to student groups to correct and maintain efficient systems.

From there, I was hired into Technical Services as a Senior Energy Services Engineer. While there, I would go into the industrial facilities of our customers and solve problems for them. It led to the Power Quality projects and my teaching it nationwide.

Why don't yo just ask how it was done, instead of assuming some ridiculous idea and accusing me of it?

Gosh, Eikka, it you do not like it, just say so. But stop assuming you understand what you apparently do not. I was Plant Engineer for manufacturing in Primary Metals and Plastics molding and extrusion, but had no degree in "Primary Metals Engineering", because I took care of the machinery and the facilities and the Maintenance Department as well, in the 4-acre manufacturing plant, I did not make decisions in metallurgy.

When I was hired as a Integrated Circuit Test Engineer, it was based on my previous work for the company, not some paper I got from a school somewhere. When hired into Technical Services, it was the same progression.

"But there is something else about the speech of psychopaths that is equally puzzling: their frequent use of contradictory and logically inconsistent statements that usually escape detection"

We know you are full of shit. Youve PROVEN that many times over.

I: "You're not a serial killer?"

I: You're saying you're not a serial killer now, but you've serially killed."
