...chemicals to control pests in his vegetable farm. However, he was not completely satisfied with various botanical pest control measures being promoted in northern Thailand. He reports that even though certain natural insect repellents were beneficial, their effects were too limited. Additionally, finding adequate amounts of necessary raw plant materials and processing them into sprays was laborious and time consuming. When Mr. Prakrit first heard about wood vinegar in 2000 he was intrigued. Compelled by the idea of a natural by-product of charcoal production that can control pests and diseases of crops, he bought his first bottle. Having used the product, Mr. Prakrit was pleased with the ease of mixing and application. Ultimately, after observing much fewer insect pests and fungal diseases on his crops, he became convinced of the effectiveness of wood vinegar. Not long afterwards, Mr. Prakrit became self sufficient in producing both charcoal and wood vinegar with a 200-liter horizontal drum kiln. He has been an advocate of wood vinegar ever since. Wood vinegar (pryoligneous liquor) is rapidly gaining acceptance as an essential Asian natural farming input. Reported agricultural use as a fertilizer and growth-promoting agent goes back to the 1930s, making the product a relatively new innovation. Uses of Wood Vinegar According to Thailand’s Department of Agriculture, wood vinegar has the following broad benefits: • Improvement of soil quality • Elimination of pests •...

...Activated Charcoal: Good or Bad? Activated charcoal is charcoal that has been treated with oxygen, which makes it more porous and increases its surface area. This also increases its capacity to absorb gases and liquids, which works by chemically binding the impurities to the carbon surface. Activated charcoal is most typically utilized to remove odorous substances from the atmosphere. Wood, peat, coconut shells, coal and sawdust are the most common materials used for making activated charcoal. Activated charcoal is most commonly found in aquarium filters, drinking-water filters and air filters; and has a role in the treatment of ingested poisons for humans. What is Charcoal? Charcoal is produced from the combustion of plant material, most typically wood, and closely resembles coal. It is extensively produced in the developing world, where it is used as a fuel for cooking and heating requirements. It is produced by heating wood at a low temperature in the absence of oxygen. All that remains after this process is the black carboniferous material know as charcoal. Activated Charcoal for Human Health Activated charcoal is utilized in human health, particularly in the treatment of poisoning, where it is ingested to counter the effects of a chemical. It is generally produced in a powdered form, which can be mixed with water and consumed as a suspension, or as a food supplement for where it comes in small, readily digested tablets or capsules. This form of activated charcoal is...

...Advantages of using Paper Charcoal 1. Concentrated. Since Paper Charcoals are created from compressing combustible material such as paper, it is denser, harder, and more compact compared to other charcoals. 2. Slow-burning. The compression process allows the paper charcoal to burn for a lot longer than if it was loose in its original form. 3. More efficient. Along with the compactness of the paper charcoal is the increase in heating value. This greater efficiency can be attributed to their low moisture and density. 4. Availability. Paper is the main component in producing this product. So where do we get this paper? Look around you, and there are loads of paper materials here, there, and everywhere. 5. Easily stored. The size and shape of paper charcoal make them easily be stored. We can readily pile them in several heaps because of their fun shapes like cubical, spherical, cylindrical, or rectangular blocks. They are likewise clean to handle and be packed into bags. 6. Cheaper. Since this charcoal can be domestically made from waste paper, they are consequently less expensive to produce, and thereby sold at lower prices. 7. Renewable. This charcoal makes use of waste materials which are common and renewable. Hence, we are ensured of the sustainability of such fuel source. 8. Easier to lit. The use of paper as the main component makes it easier to light compared to wood charcoals. Therefore, the use of gas, plastic and other methods of ignition will no longer be necessary. 9...

...White coal is a form of fuel produced by drying chopped wood over a fire. It differs from charcoal which is carbonised wood. White coal was used in England to smelt lead ore from the mid-sixteenth to the late seventeenth centuries. It produces more heat than green wood but less than charcoal and thus prevents the lead evaporating.[1] White coal could be used mixed with charcoal for other industrial uses than lead smelting.[2] White coal was produced in distinctive circular pits with a channel, known as Q-pits. They are frequently found in the woods of South Yorkshire. Nowadays white coal is made from [3] * Groundnut shells * Cotton hulls and salks * Castor seed shells * Forest leaves; wood chips and shavings * Sugarcane bagasse * Rice husk and paddy straw * Mustard waste * Coir dust * Coffee husk * Sunflower waste * Maize stalks * Bajra cobs * Sesame seeds oil cake * Wheat straw Benefits of white coal:[4][5][6] * White coal is cheaper than coal and fire wood. * There is no sulphur in the white coal, therefore no toxic gases. * Moisture content is nil. * Biomass briquettes have a higher practical thermal value. * Briquettes have consistent quality, have high burning efficiency, and are ideally sized for complete combustion. * Combustion is more uniform compared to coal and boiler response to changes in steam requirements is faster, due to higher quantity of volatile matter in briquettes. *...

...Medium: Charcoal, Graphite, Carbon on White Paper Step One: I am using charcoal for the background and graphite for the subject. I'm using Arches 140 lbs hot press watercolor paper for this drawing. This is one of my favorite papers. It has enough tooth to create dark values yet is smooth enough for very delicate textures. In this first step, I have cut out the shape of my subject(s) in frisket film and applied it to the paper. Then, I applied 3b soft charcoal to the background to begin creating a wood texture. Step Two: Next, I blended the charcoal with a piece of felt and added the beginnings of wood grain. I repeated this several times to build up a solid tone. After pulling out some highlights with a clic eraser, I used a sharp hard charcoal pencil to create shadows to help create slivers and chips in the wood. I also applied masking tape at this point. I will be drawing masking tape in these areas later. Some of the wood texture will show through from the previous step and give my drawn masking tape a little more transparency. Step Three: Then, I sprayed the drawing with fixative, Peeled off the frisket and began rendering the subjects. I used a 6h graphite pencil to add tone to the paper and blended with a chamois. In some areas, I applied the graphite with the chamois. For those of you that haven’t tried blending with a chamois, it can produce incredibly subtle tones – almost like an air brush.

...Africa) We are also fortunate that both Chidumayo and Gumbo are passionate about charcoal! (We will be featuring Dr. Gumbo’s presentation in our next review.) When we learned Dr. Chidumayo would be honored at the international ATBC-SCB conference in Arusha, Tanzania, in June (where we organized a symposium and workshop on charcoal) we pounced on him! Dr. Emmanuel Chidumayo is considered the dean of African tropical ecologist. He presented at TCP's charcoal symposium. Dr. Chidumayo was gracious enough to present at our symposium and participate in our workshop. (I was also lucky enough to be seated next to him at dinner where he regaled me with the stories about how he began his career as an ecologist, his time in government, and his passion for conservation.) Dr. Chidumayo’s presentation, “Environmental Impacts of Charcoal Production in Tropical Ecosystems of the World,” is a treasure trove of information. In addition to the scholarly research, my favorite part is the takeaway message, which I’ve transcribed below: The charcoal industry has great potential to contribute to rural development because production utilizes locally available and potentially renewable resources. The charcoal industry can generate employment and local income in both rural and urban areas. Additionally, Dr. Chidumayo points to the following necessary changes in policies: 1. Recognition of charcoal as a key source of energy. 2. Establishment of specific institutions to implement...

...Charcoal is a light, black residue, consisting of carbon and any remaining ash, obtained by removing water and other volatile constituents from animal and vegetation substances. Charcoal is usually produced by slow pyrolysis, the heating of wood or other substances in the absence of oxygen (see char and biochar). It is usually an impure form of carbon as it contains ash; however, sugarcharcoal is among the purest forms of carbon readily available, particularly if it is not made by heating but by a dehydration reaction withsulfuric acid to minimise the introduction of new impurities, as impurities can be removed from the sugar in advance. The resulting soft, brittle, lightweight, black, porous material resembles coal. Subtitle: A Boise State University study proves that low-energy feedstocks can be densified and when combusted produce heat output comparable to higher energy content fuels. By Owen McDougal, Seth Eidemiller, Nick Weires. November 23, 2010 By the way, according to one of those online dictionaries, “feedstock” refers to “the raw material that is required for an industrial process.“ Intro Research at Boise State University in Idaho, explored both the caloric content and shape to optimize burn efficiency of the biobriquettes. The energy content of briquettes ranged from 4.48 to 5.95 kilojoule per gram (kJ/g) depending on composition, whereas the energy content of sawdust, charcoal and wood pellets ranged from 7.24 to 8.25 kJ/g.

...Fuel from the Fields Charcoal B a c k g r o u n d More than 2 billion people use wood, charcoal, dung or agricultural residues as the primary fuel for their cooking and heating needs, leading to significant health, economic and environmental consequences. Burning wood or agricultural residues produces smoke with a variety of irritant pollutants, some of which are known carcinogens. More than 1.5 million deaths a year are caused by acute respiratory infections from breathing smoke from indoor cooking fires. Women and children are generally exposed to the greatest levels of pollutants and it is children who suffer the greatest health risk – respiratory infections are the leading cause of death of young children worldwide. Small-scale subsistence farmers who make less than US$2 per day may use wood charcoal for cooking fuel. In areas where wood is scarce and farmers are not able to collect it themselves, the cost of cooking fuel is a significant drain on their limited resources. An estimated 50 billion hours are spent collecting firewood each year and families can spend over 25% of their income on fuel, leaving them with less income to cover other basic needs such as medicine, food and clean water. For comparison, even the poorest 20% of the U.S. population spends only 1% of their income on energy for their household. In the year 2000, indoor air pollution from solid fuel use was responsible for more than 1.6 million annual deaths and 2.7% of the global burden of disease. -World...

...CHARCOAL AS AN ALTERNATIVE INK A Science Investigatory Project Presented to the Faculty of the Special Science Class Leonora S. Salapantan National High School San Miguel, Iloilo CRIS BERNADETTE S. CALDEDERO Special Science Class fourth year Section A March 2015 09071949701 Chapter I Introduction Background of the Study One of the most important historical applications of wood charcoal was as a constituent of gunpowder. It was also used in metallurgical operations as a reducing agent, but its application has been diminished by the introduction of coke, anthracite smalls, etc. A limited quantity is made up into the form of drawing crayons; but the greatest amount is used as a fuel, which burns hotter and cleaner than wood. Charcoal is often used by blacksmiths, for cooking, and for other industrial applications. One additional use of charcoal rediscovered recently is in horticulture. Although American gardeners have been using charcoal for a short while, research on Terra preta soils in the Amazon has found the widespread use of biochar by pre-Columbian natives to turn otherwise unproductive soil into very rich soil. The technique may find modern application, both to improve soils and as a means of carbon sequestration. The world today is suffering for an economic crisis; many people seem to realize the importance of each item that needs to be bought. Ink is an ordinary item but prevalent in everyday use. Some things that provide ink for its functions...
