1 1G Toucan TLUD for Biochar Production by Hugh McLaughlin, PhD, PE, Alterna Biocarbon Inc. , January 2010 Version Introduction to Biochar and TLUD pyrolysis Biochar is a new approach to improving soils based on the ancient practice known as “Terra Preta”, where soils in the Amazon were enhanced by the addition of charcoal. . Since any agricultural utilization of biochar starts with obtaining the biochar, and since biochar is not yet a widely available commercial product, one challenge is obtaining reasonable quality biochar. This memo outlines a simple device and method for making small quantities of consistent, high-purity and easy-to-use biochar, suitable for home gardeners for use in potting soils and gardens. One method of making good quality biochar is called Top-Lit UpDraft pyrolysis, commonly referred to as “TLUD” (Tee-lud). The TLUD principles are explained in various resources (just Google “TLUD”), but also will be evident in the discussion that follows. TLUDs were deve

Paper II. 3 BIOCHAR: A WAY FORWARD FOR INDIA AND THE WORLD Robert Whitfield, Action for a Global Climate Community 1. Introduction Biochar can sequester massive amounts of carbon in the soil for hundreds to thousands of yearsi . It has the potential to be an efficient carbon sink whilst providing strong co-benefits. Pre-Columbian Amazonian Indians used it to enhance soil productivity and made it by smouldering agricultural waste. They called it “Terra Preta de Indio. ” Its modern equivalent is being developed using pyrolysis to heat biomass in the absence of oxygen. Modern biochar production can be combined with biofuel production in a process that is energy positive - producing 3-9 times more energy than invested, and carbonnegativeii - withdrawing CO2 from the atmosphere and rebuilding geological carbon sinks. With temperature thresholds, or “tipping points”, as close as ten years away for abrupt and irreversible climate changes, including catastrophic sea-level rise, the need

The influence of biochar on nitrogen (N) transformation
processes in soil is not fully understood.
This study assessed the
influence of four biochars (wood and poultry manure biochars
synthesized at 400°C, nonactivated, and at 550°C, activated,
abbreviated as: W400, PM400, W550, PM550, respectively)

The influence of biochar on nitrogen (N) transformation processes in soil is not fully understood. This study assessed the influence of four biochars (wood and poultry manure biochars synthesized at 400°C, nonactivated, and at 550°C, activated, abbreviated as: W400, PM400, W550, PM550, respectively) on nitrous oxide (N2 O) emission and N leaching from an Alfisol and a Vertisol. Repacked soil columns were subjected to three wetting–drying (W–D) cycles to achieve a range of water-filled pore space (WFPS) over a 5-mo period. During the first two W–D cycles, W400 and W550 had inconsistent effects on N2 O emissions and the soils amended with PM400 produced higher N2 O emissions relative to the control. The initially greater N2 O emission from the PM400 soils was ascribed to its higher labile intrinsic N content than the other biochars. During the third W–D cycle, all biochar treatments consistently decreased N2 O emissions, cumulatively by 14 to 73% from the Alfisol and by 23 to 52% fr

Biochar and climate change Standard Note: SN/SC/5144 Last updated: 03 September 2009 Author: Oliver Bennett, Environment Specialist Section Science and Environment Summary • This note briefly introduces biochar as a measure to tackle climate change. • Biochar is created by burning organic material to produce a charcoal-like substance. • When buried in soil the carbon contained within biochar may be isolated from the atmosphere for long periods. • Some commentators believe that biochar will have an extremely important role in reducing atmospheric concentrations of greenhouse gases—helping to avoid dangerous climate change and improving agricultural productivity. • Other commentators believe that the benefits are overstated and that there could be negative environmental impacts. • Some countries are seeking biochar mitigation to be included in the international climate change framework being negotiated in 2009.

The Vertical Aeroponic Growing System We are developers of a new agricultural growing system developed over the years in Italy, Hawaii and California. The system is a growing environment housed in an enclosure called a BIOSHELTER ®. Within this Bioshelter is a highly efficient growing system utilizing horizontal hydroponic growing beds and many vertical aeroponic growing tubes. Pumps powered by solar energy and monitored by a computer pumps nutrients to thousands of the growing tubes. These Bioshelters have 6 to 7 times the output of conventional greenhouses. Typical products include vegetables, sprouts, berries, flowers, and specialty plants such as pharmaceuticals We are in the process of seeking sustainable development projects like the MASDAR Initiative to launch highly productive vertical farms, which not only function as climate buffers and sequesterers of carbon dioxide for the inhabitants, but they also produce oxygen and high value vegetable and nutraceutical crop which c
