A briquette

A briquette (or briquet) is a compacted block of coal dust or other burnable biomass material such as charcoal, sawdust, wood chips, compost, or paper used for fuel and lighting to start a fire. The word originates from the French language and is linked to brick (Oxford English Dictionary, 2009). Many discarded products, such as wood excesses and sawdust from the wood manufacturing, community leftovers, bagasse from sugar cane processing, or charcoal powder are briquetted to rise firmness and transportability. Briquetting is frequently a huge scale commercial activity and often the raw substances will be carbonized during the procedure to produce a functional gas and also a more user friendly briquette. Some enhanced cooktops have been designed specially to be used with briquettes. Clean dung briquettes finally can be made from compost. (Karekezi 1997).
Fuel briquettes can be made from waste resources that usually go to waste, comprising sawdust, paper, charcoal, fine leaves, peelings and other agricultural wastes like animal manures (Harley, 2014). Fuel briquettes are an ecologically friendly fuel source that are used to create a fire. They function as an substitute to kindling and firelighters (the latter are the same to fuel briquettes but often also comprise fossil fuel). Fuel briquettes are used in Kigali, Rwanda, amongst other places (Appropedia, 2012). A women’s cooperative, ACEN/COOCEN, is in charge for the development that turns rubbish into the environmental briquettes. This will lessen CO2 productions and deforestation. Household excess is collected from 12,000 Rwandan families and carried to a facility in Kigali. From there, materials rich in cellulose such as tree fibers, cardboard, paper, compost and wood scraps are placed together, dried and compressed. They are then turned into briquettes which can function similar purpose as wood but are cleaner to burn and more effective to use. Fourteen tons of briquettes are made each day. They are vended to schools, prisons, factories, etc. and are not usually used in households (Karekezi 1997).
Briquettes burning does not produce smoke and sparks. With the same quantity of firewood briquettes release heat much longer. Fuel briquettes are pressed, and therefore need much less storage space. The great density stops penetration of moisture and rot, and it can be kept unlimited time (Belfuel, 2015).
The coconut fruit produces 40 % coconut husks comprising 30 % fiber, with dust making up the rest. The chemical structure of coconut husks contains cellulose, lignin, pyroligneous acid, gas, charcoal, tar, tannin, and potassium. Coconut dust has high lignin and cellulose content. The components confined in the covering of coco dusts and coconut fibers are resilient to bacteria and fungi.
Coconut husk and shells are an outstanding biomass fuel and are a good source of charcoal as well. The most important benefit of using coconut biomass as a fuel is that coconut is a constant crop and it is accessible round the year so there is a continuous full year source. Activated carbon contrived from coconut shell is considered tremendously effective for the removal of contaminations in wastewater treatment processes.
Coconut husk has great quantity of lignin and cellulose, and that is why it has a great calorific rate of 18.62MJ/kg. The chemical structure of coconut husks comprises of cellulose, lignin, pyroligneous acid, gas, charcoal, tar, tannin, and potassium. The major use of coconut husks is in direct burning in order to make charcoal, otherwise husks will be just thrown away. Coconut husk can be converted into a value-added fuel source which can interchange wood and other traditional fuel sources. In terms of the accessibility and prices of coconut husks, they have good potential for use in power plants (BioEnergy Consult, 2012).
You may not know this but the husk of the coconut, also identified as coir, is made into numerous products that are used day-to-day like carpets, ropes, door mats, mattresses, car seat covers, brushes, coats, etc. This fibrous material is hard and extremely resilient to sea water. A large container of coconut husk can cost as little as $10 at the garden or pet materials store. Dried husk makes a great fire for campfires and bed of coals after, which is also applicable for BBQ cooking (Mike B, 2017).
Another environmentally friendly nature of coconut husk is its capability to be used as a developing medium. For example, it can be used to cultivate flowers such as orchids, roses, et cetera. It can also function as a elastic growing material for numerous other major food manufactures. This is related to its capability to interact with nutrients and hold onto calcium and magnesium while gently discharging potassium and nitrogen. These are crucial nutrients for plant development.
Coconuts naturally contains a compound that encourages the expansion of helpful bacteria, known as lignin. Coconut husk can also function as bio fuel which is a source of charcoal (Ghana, 2016).
Sawdust or wood waste is a waste product of woodworking procedures for instance sawing, milling, planing, routing, drilling and sanding. It is consist of fine elements of wood. These processes can be executed by woodworking equipment, convenient power apparatuses or through the usage of hand tools.
A main usage of sawdust is for particleboard; grainy sawdust may be used for wood pulp. Sawdust has a selection of other useful uses, comprising serving as a mulch, unique displays, or as a fuel. Until the introduction of refrigeration, it was commonly used in icehouses to retain ice stationary during the summer. It is also sometimes used to penetrate up liquid leaks, letting the leak to be simply gathered or swept away (Demir, 2008).
Sawdust is used in the production of charcoal briquettes. The entitlement for the creation of the original marketable charcoal briquettes goes to Henry Ford who invented them from the wood remains and sawdust formed by his automobile workshop. Airborne sawdust and sawdust gatherings present a number of health and safety risks. Wood dust becomes a potential health problem when, for instance, the wood particles, from processes such as sanding, turn out to be airborne and are inhaled. Wood dust is a known human pollutant. Certain woods and their dust encompass toxins that can produce severe allergic reactions (Henderson, 2010).
Only few people realize it, but there are plenty of ways and means that sawdust is very usable in the present world, so when you’ve got some setting around you might want to place it to good use too. Sawdust can be reused at your house and have a hugely valuable result to you (Miller, 2017). Use of sawdust in enhanced cook stoves among others, is considered highly significant in the climate change alleviation argument (Ezzati et al., 2002; IIED, 2010).
Recycling of wood wastes is not done by all wood trades, specifically by smallholders. These rubbishes are usually used as fuel for brick constructing and also for cooking. At medium or large establishments some of the wastes, like: dry sawdust and chips, are used as fuel for wood drying procedure. The heating or greasy value is a significant factor when evaluating the applicability of a burnable material as a fuel (Zafar, 2017).
