Secondly, how are you extracting your cellulose? Lignin is incredibly tough and is the part of wood that actually does all the structural stuff.
Thirdly, how much catalyst do you need along with how much cellulase?
You can’t just throw them together are expect it to convert stuff. How much energy (heat) do you need to start things off?
1500 calories is starvation diet, 3000 is closer to actual.
Now we are closer to 1200kg of DRY wood needed per year. When harvested this will be something like 1500kg to 2500kg. I guess you’d want to process the wood wet to minimise losses but that is a lot of heavy processing.
How much wood can you reliably get from your coppice?
Have you tried eating and surviving on pure glucose?
What’s it actually like getting all of the ‘trivial’ other vitamins and minerals that humans need?
I think you’re vastly underestimating the resources required and not really respecting the massively complex systems within our bodies that focus on extracting what we need from plant life.

...The other amino acids and micronutrients would also be stockpiled, but their volumes would be trivial.
Cellulose had the great advantage of being everywhere, including upon the ubiquitous "weeds" of the fields or the fallen logs and branches of the forest. There is no need to cut down trees or wait seasons for their fruit/nuts, we merely need to use coppicing to harvest wood over and over without ever needing to disrupt the land.

Have you come across the idea of edible forest gardens?
We have a forum here dedicated to forest gardens which in theory can supply all you need in terms of nutrition.
Have you discovered lamb's quarters yet? No need for processing with that, and it grows literally as a weed all over the place. Plus it's delicious, and very nutritious.
In fact if you learn enough about all the trees and weeds that grow around you, and plant suitable ones along with them, you could probably eat as much as you want without ever using up your emergency cellulose stockpile. Many apples will store for months. Olives will keep for a year or two. Dehydrated fruits and vegetables keep for years. Nuts provide oil and protein as well as glucose. Some trees have leaves that edible, especially when they are young in the spring.

If you ever had a McDonalds shake you have been eating wood fiber, and it is nothing new.
I grew up on a dairy farm and the creamery we sold our milk too, figured out how to take milk and dehydrate it, and mixing it with cellulose were able to give milk a huge long shelf life. This appealed to McDonalds as they could have big boxes of milk shake mix last much longer for their franchises. I learned about this in 1992 when I worked on the farm.
I am sure other companies also use this cellulose to make dairy products last much longer too. I know the creamery we sold our milk too, a Co-Op Creamery, patented their milk shake formula so it is NOT a McDonald's only thing.
When you read the Snopes fact checking it says that rumors about McDonalds shakes are false, but they are wrong. because the dairy product is an approved food ingredient. We can debate whether that is something that should be, or should not be, in the mix, but its fully considered a food product. Myself, i see no harm in mixing in some sawdust as a filler in dehydrated milk, but that is just me.
Another huge cellulose commodity we consume commercially is carageen. My cousin works at a giant factor here in Maine that produces that; its cellulose from seaweed and is in EVERYTHING we eat. Its what makes jello-jell up, and in literally everything... again, even in McDonalds milkshakes.
As a farmer I LOVE that factory because I could get the waste from that food plant and spread it on my farm fields. It acted as a lime, but also increased organic matter, and was literally me spreading tons of seaweed across acres of land for FREE.
But cellulose; we have been eating it for years. You just never knew it.

Our bodies need proteins, minerals, vitamins, and fats from outside sources. Our bodies need hardly any sugar, and our bodies can make the sugar it needs from protein. I think it is a really cool idea to store sugar in a form that things don't bother, but I need to know more about where to get the protein, fats, minerals, etc. You talk about supplements, which are easy to get right now, but if the goal is to be self sustainable, we need a way to get those things long term regardless of whether those factories keep producing or not.
I think Burra has a good idea on how to do that. Forest gardens, foraging, normal gardens, etc. Your idea about hunting rabbits is good too. You can hunt or farm a lot of the things you need. You can grow and forage the rest. I'm just wondering if, by the time you have room to grow or forage all the plants, with systems setup for all the animals (hunted or farmed), whether you would need to deal with the cellulose at all?

James Bridger wrote:The biggest problem I see, and it's the same thing I generally see when someone says something to the effect of "if only we'd do XYX then nobody would have to work", is that you're not accounting for all the other people that would have to work, in order to make XYZ happen, so that you don't have to work. For example.....you talked about using NaClO2 to make lignin....that requires people to work in industrial labs to make. You talked about making your own, using electricity.....someone is going to have to work, in order to make solar panels or whatever for you to produce electricity. You talked about eating supplements/vitamins.....again, those are made in some factory by wage slaves. Same with the solar panels you talked about to produce water.
Anything short of reverting to a hunter/gatherer society is going to require others to work for you, and they're going to need to be payed with some sort of exchange medium (money) for their wages.
Steve Zoma wrote:I just wonder what is so horrible about work anyway?
For someone who had cancer and could not work meaningfully for four years, I appreciate being able to work now.
And there really is no “wage slave”. My stocks are doing well currently at 11% interest, but while that is above average for stocks my job is a lot better in terms of return on investment. I put $50 bucks worth of gas in my car at the start of the week and net myself $1200 from it by the end of it. That is a pay back of 2500%. You can’t get that kind of return doing anything else legally…

It looks like there is a fair amount of research going on in that direction already.

Black liquor is created during the Kraft making
Process and back when the USA was given out carbon credits for producing biofuels, many paper companies were making good money on the biofuel designation by burning the alcohols coming out of their processed woods. Because of the tenbicality of biofuels producing so much power for the grid, it was one reason why they had to stop paying biofuel subsidies.
Incidentally the largest producer of this kind of energy does not come in tree form or corn, but cattails. Whereas corn can produce 400 gallons per acre, cattails gets a whopping 600 gallons per acre. Minnesota alone could produce enough fuel without using crop land to power itself and many states besides.
Trace Oswald wrote:For me, it seems planting a big garden is far simpler, more satisfying, and certainly ends up with a product that is much better tasting to eat. Burra mentioned food forests that can round out many of the missing nutrients and flavors. Add some chickens and you have all areas of nutrition covered. I think in this case, natural is much better than an overly complex method that allows me to eat wood.
Thom Bri wrote:My point being, food is super cheap. Attempting to reduce your participation in the economy by extreme methods is unnecessary. A minimum wage worker need only work 33 hours to cover basic yearly food needs eating mainly grain and beans.
Wage slavery is mainly about other things. A car, a house, entertainment, a girlfriend, fashionable clothing, exotic foods. Social needs, in other words. Food in itself is so cheap in modern America as to be hardly an issue.
Samantha Lewis wrote:I think stockpiling food is essential. For me, it is only being responsible to be prepared to feed my family for years without outside help. We have bags and barrels of grains and legumes. Tons of dried, stored food, salt and fat. I don’t want to eat that stuff myself though. That is just to give me a cushion so I don’t worry.
I want to eat out of my garden whenever possible.
If you are what you eat, I want my food to be the highest, most vibrant materials that I can produce or procure.
We can only eat so much food each day. I like to get as much nutrition as I can.
I think permaculture paints a picture for us to create carefree, perennial food growing systems.
If you build a Hugelkulture bed and populate it with perennials you like to eat, you can have food coming back year after year and you don’t have to do much work. Maybe try sun-chokes, they probably have a fair amount of cellulose.
This movie will give you all the info you need to get started with Hugelkulture!

You can add a lot of nutrition and resilience to your system by running animals but they do take more care.
Sheep and rabbits do a great job of turning trees into human food. You don’t have to eat them, just letting the plant material pass through the animal kingdom has great benefit to the land, the gardener and makes the minerals more bioavailable in the foods you grow.
I have found the systems I create are much easier to maintain the closer they are to nature.
Although the processes you are describing of cellulose to glucose may work to provide human sustenance, it seems like it is a long way from nature. While we humans are amazing creatures, resilient and adaptable, to me, all this extra complication makes it systemically weak, even if it is possible.
I think there is a lot to be said for what is fun for you. What brings you joy?
I like to be barefoot in the garden and watch my animals graze the hills. I like to eat food and wear clothes made by my own hands.
What do you want to spend the moments of your life doing?
Douglas Alpenstock wrote:Mr. Young, I wonder if you have started with a conclusion and are looking to cherry pick ideas that support it. Personally I think that is an ineffective way to advance knowledge.
The methods of converting raw materials into food for humans, frankly, span thousands of years. They involve plants and animals in a loose symbiotic relationship. Many people here are trying to make this old knowledge available to other people wherever they live. No politics, only better living and richer soil via the labour of our hands. This benefits everyone, everywhere. My 2c.

I share many of the OP's concerns about where it's all going. I think many of us do here. But I think a lot of us haven't given up on community yet. It can be a long, tired slog alone, even if we don't have to worry about finding food we still have other needs to fill.
