Bio-Char Pellets

I didn't see a speel on this topic yet so now we have one. I wrote this to a forum for bio-pellet maker's and thought that I would pass it along to you to read. Enjoy. ______________________________________________________ Hello, I am new to the forum and to pellet making altogether really. I am an open researcher of the net at the present time have become interested in many topics I come across. The downfall of the net, for some, is that there so much information, it can boggle the mind. I ran across the videos put out by the web site on YouTube and decided to pose a question to the site administrator. They still have not gotten back to me, but I think from the posts on the forum you are a pretty busy group - he is likely looking into it. The newest thing on the 'Save the World' front is Bio-char. I asked if the pellet machine would be able to convert bio-char into a pellet form. I do know that the bio-char can be hand pressed, or screw extruded into briquettes. This is done in many countries around the world. What I think would work the best is the small pellets that your group are making. I will give a little bit of back ground for my idea. Researchers who have explored the rain forests of the Amazon have come across a soil type which is man-made. They call it 'Terra-Preta' or 'Dark Earth'. I have found out that the soil of the rain forest is not particularly suited to growing vegetation (this surprised me) and the ancient civilizations in the area would treat the soils. These plots of land they are finding today are estimated to be 100's of years old (in terms of last use) and are amazingly fertile as compared to other soils in the immediate area. They only run 4-5 feet in depth and cover the known growing plot area of the period. Today’s natives actually hunt out these plots and sell the fertile soil as an income. The keys to this fertile soil is a high carbon content and pottery chards. Both materials are very porous in nature. What happens is the nutrients that come to the treated soil gets trapped in the pores of the material and are held there, rather than being washed straight through the soil. These nutrients are then extracted from the material be the root systems of the plants as they grow. As the spaces in the material open up again they are refilled with newly arrived nutrients. This material has proven that it can remain in the soil for 100's of years - as is found in the 'Terra-Preta' plots. By the way these plots are not isolated to the Amazon they are found around the World in different areas. The thing is that the way they are made - the technique was lost. These plots around the World are being used up and the farmers are running out of nutrient rich natural (organic) soil. Some feel that the burning of the fields in the way to go as it has been done that way for ages. Well, the soil is dying and it working. The soils are being depleted. Plant matter which is made of carbon, takes its building blocks from the soil and therefore the soil is lacking carbon after centuries of use. But, because we had one lazy, or work saving generation, who knows how long ago, we have lost the technique of how to care for the soils. Tests run in Africa are showing an amazing 500+% increase in crop yields in the first year. They are still using un-organic fertilizers as that is what they thought they needed, but that can change now. Their soil is so bad in some areas that nothing would grow. If any farmer could get a 20% increase in annual yields they would be happy. The reason that the use of chemicals came into large use was because of the depleted soils. If the chemicals did not wash away (trapped in the carbon for future use) there would be less need in the future. Ideally there would be none needed in the future. So what are we doing? At present we grow plant material, burn it, and release the carbon into the atmosphere. I don't go for the global warming thing, but do feel it is not a good thing happening. The dirt on my car every day tells me that things are changing for the worse - I didn't see that as a child. What we can do is grow the plant material, burn a portion of it to covert another portion of the material back into carbon, and put that carbon back into the soil. This cuts emissions to the air (from that aspect of society) to 50% of what it was. Pellets can play a big part in this. My idea was to convert plant matter to char and the char to pellets. The pellets would be good as they are finding in test fields that the microbes in the soils like to grow in the larger pieces. 'It makes the soil happy' - they have a community of their own. You do not want too large of chunks as that makes the soil difficult to work with. Too small of piece (on surface soil) will be blown away on windy days. The windblown soil may not seem like a big thing, but the carbon has the nutrients now remember. Keep all you can on the fields instead of the forest. If you wish to recarbonize the forest soil, spread it through the forest in your spare time. It should be said here that the carbon upon introduction to the soil will deplete the soil of nutrients at first. This is the carbon 'charging' itself. The pores of the carbon are filling and will have the nutrients there; it just looks like the nutrients are gone. This is why it is a good idea to pre-charge the carbon before introduction to the soil. Mix it with compost or manure for a couple of weeks and let the pores fill. The nutrients will then be added to the soil with the carbon. This where the pottery chars they find in 'Terra-Preta' come from. They are the holding vessels from the indoor urinals and toilets - charged and stinky they were broken in the fields. This may not work as far as making pellets from bio-char goes. What about bio-char from pellets. This would be easy to test for you people. You have the machines and the wits to do it. The market is there if you want to sell the end material. Every back-yard composter, in every city will want this stuff. I hope I wasn't too long winded on this. It is an important topic, especially if you are a rural resident. City dwellers with a green thumb can help, but the rural residents hold a majority of the bio-matter. For more information Google 'bio-char' also 'making charcoal from wood' you can get into the worm castings and all that, but once the nutrients are in your soil the rest of the good things will come and live there without help.

What type of energy are our thoughts?

After reading lemonies instructable on frequently asked questions ( i really enjoyed the chapter on energy ) ive been thinking about what our thoughts are.The brain works in a bio chemical manner but what exactly are the actual thoughts? Are they energy at all?

algae+ chicken manure how to get rid of parasites and bugs, and bio diesel?

Ok so i was wondering if any of you algae growers out there have ever tried fertilizing with chicken manure and if you have found the gross bugs/ parasites/ oil crap on top/gross things, and how you got around that i tried boiling the manure in water for ten minutes to kill the stuff but it didnt seem to work? ok so ive heard of the chemical way of making bio diesel but is there any way to make bio diesel or bio gasoline or bio ethonal without nasty chemicals from the oil straight from the algae press. Im 16 and my parents dont want me to have harsh chemicals nor do i have the money to go buy them. thanks

Which are Ecologically friendly Ultraviolet ray blockers/absorbers/stabilizers that can be used in polymer?

Hey, Working on (reinforcement) bio-composite material using bamboo fibers & starch based DIY bio plastic from starch, glycerin, vinegar. I wanted to incorporate UV Protection to my composite by adding UV protective additive in polymer mix. I searched for regular additives (Benzophenone)  that are added but I want to find if any Environmentally friendly UV stabilizers are available or can be extracted from natural sources to be used in bioplastic. (chemicals consideration) 1-PABA (p-Amino benzoic acid) & 2-ZnO Please do add your valued opinions.

Wood gasifiers and safety - Carbon Monoxide poisoning - hospital

Sorry if it is in the wrong section of the forum. If it can be moved to a better place then do so. This is a quick mention to anyone that is playing around with any burners such as:    wood gas generator    bio-gas    wood gasifier    'hobo' stove I am not severely concerned but it did happen, I think it needs a mention, as it is for everyone's safety. After playing with wood gas and attempting methanol creation from a small gasifier unit for a few weeks, I had started to realize that each day I had a most annoying headache / migrane in my frontal area of my brain / head. They ended up getting so bad that my body could not tolerate them anymore and started to go into shock, causing a rather painful, endless throwing up session for many hours each time even.  It came to a point where after 3 weeks of playing with a bio-gas generator for about 4 hours a day had started to lead me into temporary blindness an hour and a half at a time. This was when I was concerned as I could not read any more instructables :( After a quick jot to the local doctors, I explained what I had been up to and I was correct. I had given myself the rather classic, and very close to death, carbon-monoxide poisoning where my doctor insisted I go to emergency at the hospital ( 2 hours away ) immediately and have someone else drive me. Pretty much equivalent to staying inside a garage with your car running for 5 hours, all the doors closed. I was very close to severe carbon monoxide poisoning and death.  At the hospital, blood was taken, analysed, and they had discovered large traces of C02 that they attempted to flush with some oxygen, but this only works to a point and they mentioned that nothing else could be done apart from telling me not to use or be near any smoke sources for at least 3 weeks and I should recover fine. I am still playing with my wood gas generators, and attempting to make methanol, but these days, after 3 days ago, I take further safety precautions to make sure it wont happen again. Such as: ventilation / exhaust fan ( I WAS OUTSIDE WHEN I WAS POISONED! DONT TAKE THIS LIGHTLY! ) keep a distance, find a better way to ignite / extinguish the burner keep your face and body out of the smoke dont watch the flames / smoke from above for any longer than 2 seconds do not taunt the Criosote by-product of wood. I am not sure which is more toxic. The smoke or this.   ( criosote / bio-crude, whatever you want to call it, it is the condensate of the burner unit containing more chemicals, very stinky) do not store criosote indoors withough a sealable container ( the smell likes to soak into things, like my kitchen ) if you know what you are doing, keep oxygen tank nearby use all protective clothing and masks, etc. There was a small arrogance in my head when playing with these units. And that is simply that I was thinking 'it is just smoke'. Wood gas generators are generating a much more toxic smoke than just sitting around your camping fire and should not be considered to be something to play with, without proper valves, pipes, burn off points etc. It contains on some scale: carbon-monoxide, methane, acids ( acetic ), tar and many other defects that will cause you issues if you are not careful. Keep it safe guys, this was a rather difficult one for explination, but I do not want someone other than me to be in that same sickness / position as I was with the poisoning, as it is the most painful experience I had yet had.  Worse than me hitting a tree head on at 80km/h. Worse than falling 2 stories off a cliff onto rocks. Worse than being hit by a car and thrown over it's windscreen. Worse than the feeling of an unsuccessful home made rocket launch. All of these above I have had happen to me, and the poisoning was by far the worst and I was scared more for my life than than any above accidents. It is not a very nice feeling, it is a deathly, sickly, useless feeling, blindness is not far away from death if found in this situation. Oxygen / fresh air is the only thing to help you if poisoned, even if in hospital. Keep it safe guys. If you want me to write up a full on poster on wood-gas / wood-heater safety I can or even just a propper write - up on general safety with this smoke and the wood gas units etc. Ask please and I will. Hospital staff will most likely give you 'items of interest' for instructables if you just ask them too. I have a heap of things from a stethoscope to vials to 'red dots' for homemade ECG machines. They tend to like crazies like me that make weird stuffs .. i hope ive gotten the point across anyway.
