A comparative analysis of emissions from bagasse charcoal and wood charcoal
… of cheap cooking fuel source. Currently, lump charcoal, the cooking fuel of Haiti, is made by carbonizing trees in ditches before selling the charcoal at market. However, Haiti is now 98% deforested and must find a way to prepare their food that does not destroy their land. The idea for this …

Designing the Sugar Cane Charcoal Extruder
The Sugar Cane Charcoal Extruder compresses carbonized sugar cane into charcoal briquettes. that are environmentally-friendly and comparable to wood charcoal in burn performance, cost, and durability. Originally developed in the fall semester of 2004 in the MIT course 2.009, Product Engineering …

The macro-charcoal signature in Bwabwata National park, north-east, Namibia: Calibrating surface macro-charcoal with environmental variables
… changes throught the use of paleao-proxies. Charcoal - burned pieces of vegetation - is a proxy for fire and vegetation history. However, little is known about the relationship between charcoal found in sediment and environmental features in the savanna biome. This study aims to fill the …

The adsorption of ampholytes on activated charcoal
… acids, vitamins and related compounds on one charcoal. When this was completed representative compounds were taken for further study with other charcoals, to determine whether observed differences in adsorption were due to qualitative differences existing within the charcoal as well as to the …

Therapy of porphyria with oral activated charcoal
The porphyrias are a group of disorders of the haem biosynthetic pathway. Each is ascribed to a unique deficiency of an enzyme of this pathway. Figure 1.1 shows this pathway and the position of the affected enzyme in each form of porphyria. PORPHYRINOGENS AND PORPHYRINS The porphyrinogens are …

Economic feasibility of bagasse charcoal in Haiti
The economics of implementing bagasse-based charcoal manufacturing in Haiti was investigated. From these main inputs, three different manufacturing economic scenarios were modeled using a simple, dynamic excel spreadsheet. The first model reflects single family implementation, which reasonable …

Converting sugarcane waste into charcoal for Haiti
… traditionally relied on wood and wood-derived charcoal as their primary fuel source for indoor cooking. This resource has proven to be unsustainable, however, as over 90% of the Haitian countryside has already been deforested and wood is now in low supply. As a poor country, importing fuel is …

Charcoal chemistry : developing a proxy for paleofire regimes.
… biogeochemical cycling and ecosystem processes. Charcoal particles in the geological record may contain information on several aspects of paleowildfire regimes. The fire intensity, the energy produced during a fire, is poorly understood for fires that occurred in the past. I propose that the …

Climatic reconstruction using wood charcoal from archaeological sites
… thesis assesses the feasibility of using wood charcoal from archaeological sites as a palaeoclimatic indicator. Three techniques are described: (i) charcoal identification from Xylem Anatomy. (ii) Ecologically Diagnostic Xylem Analysis and (iii) stable carbon isotope analysis on wood charcoal. …

Adsorption of Pollutants on Charcoal Cloth in Simulated Guard Filters
… and o-xylene from air by adsorption on activated charcoal cloth and the subsequent regeneration of the cloth in a stream of hot air was investigated. The above four solvents were chosen as typical organics, due to their less hazardous properties. They are all in reasonably common use and relevant …

Low cost, small-scale charcoal production in the Western Cape
Domestic grade charcoal with a fixed carbon content of at least 80 was successfully produced from the alien species Acacia Saligna. Carbonisation was effected using a Tongan drum kiln and average yields on a dry basis of 19.1 (excluding fines production) were attained. With fines included, the …

The Recovery of Valuable Vapour Phase Solvents using Activated Charcoal Cloth
… vapours from air by adsorption onto activated charcoal cloth and their subsequent recovery by regenerating the cloth with low pressure steam was investigated. Additionally, present market areas for activated charcoals have been presented as well as outlining new market fields for activated …

Reconstructing the late pleistocene palaeoenvironment of the Richtersveld using fossil charcoal
… data in the form of fossil wood charcoal assemblages that span a sequence from the last glacial maximum (LGM) to ~14 500 yrs BP. The present study analysed the fossil charcoal deposits from the rockshelter in order to reconstruct woody species assemblage patterns as a proxy for …

Design of a crushing and agglomeration process for manufacturing bagasse charcoal
In Haiti, wood and wood charcoal are common fuels for cooking. This practice has contributed to deforestation, leading to erosion and fatal floods. The availability of charcoal made from a different source other than wood, such as agricultural waste, might provide Haitians with an alternative, more …
