BIOCHAR PIT KILN is one of the simplest method of converting the crop residue and other biomass into Biochar / charcoal The farmers can easily create pits / trenches and convert the biomass residue (apart from using for compost, mulch, etc) otherwise wasted by burning in the fields openly. The tribals at Yerragondapalem (supported by NABARD / Sri Sai Educational Society), in Andhra Pradesh were trained in this method (GSBC Project), they are able to produce the biochar, preparing biochar compost and applying to their fields.

* About 30% biochar production
* 3 to 4 days for a batch of charcoal production
* Continuous hot water access (pot 1)
* Highly suitable for institutional cooking and as well making biochar
* Additional heat generated by flaring the pyrolysis gases, used for cooking
* Mitigation of the emissions during the pyrolysis by flaring
* Costs about Rs. 3000 for a 2’ width x 5’ depth x 6’ hight (in feet) “GEO Biochar pit stove”. (cost including, tin sheet for cover, digging the pit, three pot stove and chimney.)
*_"GEO BIOCHAR STOVE" is designed by Dr. N. Sai Bhaskar Reddy, CEO, GEO. Demonstrated to farmers under the project Good Stoves and Biochar Communities Project, being supported by, France

Thought of this pic the other day and thought you would like to see it. This is a charcoal building that was used as the cold room at a tented camp I stayed at in Kenya in the bush. They would pour water down the walls and the evaporative effect would cool the room down pretty well, probably around 15C. So they kept all the food for the camp in there.Best Authentic Sneakers | Nike Air Force 1 High


Arborists in Chicago are studying the results of biochar on trees growing in urban soils that are typically hostile to trees. This research is part of a larger urban-soils study that includes applications of biochar in greenhouse and field plot settings at The Morton Arboretum. The Bartlett Tree Research Laboratories have also been testing adding biochar to the soil mix when planting trees. More information and media coverage of this study about biochar and urban tree care can be found on the Bartlett Tree Experts web site.Asics footwear | GOLF NIKE SHOES

This is a very simple Biochar TLUD kiln recently designed for Sarada Mutt (Holy Mother) named as HOLY MOTHER BIOCHAR KILN, at Almora, Uttarakhand, India. Bricks and clay is used in the construction. This is a TLUD kiln. The biomass is to be added continuously as the fire continuous. The person adding the biomass to the kiln should be cautious and also use a long stick to keep away from the fire while adding the biomass. The primay air source at the bottom should be open as long as biomass is being added. As the biomass pyrolysis happens it occupies less space and more biomass can be added. It is convenient to operate during calm days i.e., less windy days. As the biomass reaches the level just below the secondary air, the process of adding the biomass should be stopped. The primary air inlet should be closed completely. After waiting for some time water should be sprinkled to extinguish the embers (quench). The biochar can be collected immediately or after some time. This is the simplest of the process of using the wasted / waste biomass to convert into biochar. Here pine needles are used for converting into biochar. Pine needles management is a big task in these parts of Himalayas, as often they lead to forest fires destroying many trees.

Biochar Industries in Kunghur NSW Australia was the setting for this momentous occasion. Monday 16th of May 2011.

With an even bigger surprise to come this statement by an Australian Biochar Expert.

“This is the first Adam Retort in Australia and it will be the first commercial Adam retort in the western world” Said Dr Paul Taylor PhD Author and Editor of the Book The Biochar Revolution. This statement had Charmaster Dolph Cooke falling off his chair.

The biochar is produced from urban lop, grape pomace, wood, miscanthus and other suitable biomasse. The biochar production is guaranteed climate-positive and free from eco-toxicological substances. The high quality biomasses are pyrolysed at 400 to 450°C to come up with particularly effective microporosity of the biochar. It is recommended to activate the biochar with ripe compost at a volume ratio of 1:1 until 1:2. We recommend the application of 10 tonnes of biochar per hectare or 1 kilogram per square meter.

he author, Gary Gilmore, explains how he designed a charcoal retort from steel drums. This is a smoke free design also the flare could be put to use.

Charcoal by Gary Gilmore video 1

First make the retort by adding air holes to the bottom of a steel drum.
Then make the afterburner by turning another steel drum into a tube.

Then start loading the wood (no more than 20% moisture) tightly packed into the retort. (This contains a great description of wood as nature's battery).

Charcoal by Gary Gilmore video 2

Once you have the wood packed in the retort, build a small fire on the top. (There is a nice description of a top lit retort system). Once the small top fire has caught, ad the afterburner (the tube) to the top of the retort.


This is the simplest and convenient method for farmers to convert the crop residue / biomass in the farm lands into Biochar 'Biochar Trench Earth Mound' / 'Staggered Biochar Trench Earth Mound' of 2 to 3 feet depth and 1.5 to 2 feet width could be made using simple tools in a agriculture fields. (deeper trenches can also be made) It is more convenient to make such trenches after ploughing the field. Trenches perpendicular to the slopes also benefit the steep sloppy areas as water harvesting means. All the crop residue otherwise burnt openly can be collected and dumped into these trenches lengthwise. More biomass can be added by pushing it with a stick. Once the trench is filled with biomass and compact, should be covered by grass / weeds / broad leaves / etc. After covering it up, soil should be spread on the trench, a lengthy mound is created. Some water could be used to make the soil compact and for sealing the mound of biomass. A small hole is left open for lighting the biomass at one end and at the other end a very small opening is left open. Once it is lit, white smoke starts emitting at the other end. Small holes to be made in a biochar lenghty trench at every 10 to 15 feet in a biochar trench and light it. Or one could create staggered trenches of 10 to 15 feet in length instead of lengthy single trenches. After 24 hours the biomass is converted into biochar, also one could see that the mound height also reduces. Any little smoke or embers should be quenched with water or covered with soil while removing the biochar from the trench.
