Briquette is an energy source derived from biomass that can be used as an alternative energy substitute, petroleum and other energy derived from fossils. Briquettes can be made from raw materials that we often find in everyday life, such as coconut shells, rice husks, husk charcoal, sawdust (sawdust), corncobs, leaves, and so on. The manufacture of briquettes is done by pressing or compacting the process which aims to increase the calorific value per unit area of a biomass that will be used as alternative energy, so that with a relatively small size of biomass, large amounts of energy will be produced. In addition, the shape of the biomass becomes more uniform, so it will be easier for the storage and distribution process.

Biomass or organic materials can be processed and used as alternative fuels, for example by making briquettes. This type of energy source is mostly obtained from forestry, livestock, and plantation products. One example of the use of biomass energy derived from coconut plantation activities is the stem, coir, and shell which are part of the coconut.

Hearing the word briquette, most people will immediately think of coal. Actually briquettes are not synonymous with coal because the definition of briquettes is a block of combustible material that is used as fuel to start and maintain a fire. The most commonly used briquettes are coal briquettes, charcoal briquettes, peat briquettes, and biomass briquettes.

Coconut Shell Briquettes

Briquettes from coconut shells have the potential to be an alternative energy that can be utilized. This is because Indonesia has a lot of coconut commodities, so the shell waste produced can be used to be processed into briquettes. The demand for coconut shell briquettes from abroad is very high. This is because, briquettes are widely used for barbecue and shisha. Especially for shisha, the use of coconut shell briquettes is considered to have good quality compared to other briquettes. In addition to having high demand, the coconut shell briquette business is also not affected by the economic crisis. Currently, 100 percent of sales of coconut shell briquettes are exported using foreign exchange rates. This makes the briquette business run in a sustainable manner, supported by the availability of abundant waste.

Coal briquettes

Coal briquettes have long been produced as a means of depleting ‘small coal’, the finely crushed coal must be produced during the mining process. Otherwise, it is difficult to burn as it is difficult to regulate adequate airflow through the flame of these small pieces; also the fuel tends to be pulled in and out of the chimney by the wind, giving off visible black smoke. The first briquettes were known as rod bombs and were cast by hand with a small amount of wet clay as a binder. These can be difficult to burn efficiently, because unburned clay produces a large ash content, blocking the flow of air through the grate. With Victorian developments in engineering, particularly hydraulic presses, it became possible to produce machine-made briquettes with minimal binder content. A tar or pitch binder is used, obtained first from gas generation and then from petrochemical sources. This binder burns out, making it a low-ash fuel. The exclusive briquette brand from the South Wales coalfields is Phurnacite, which was developed by Idris Jones for Powell Duffryn. It is intended to mimic high-quality anthracite coal, such as that of Cynheidre. It involves mixing coal mixtures from different grades and coal mine sources.

Peat briquettes

In Ireland, peat briquettes are a common type of solid fuel, largely replacing raw peat as domestic fuel. These briquettes consist of grated peat, compacted to form a fuel that is almost smokeless, slow burning, easy to store and transport. Although often used as the sole fuel for fires, they are also used to start coal fires quickly and easily.

Biomass briquettes

Biomass briquettes are made from agricultural waste and are a substitute for fossil fuels such as oil or coal, and can be used to heat boilers in factories, and also have applications in developing countries. Biomass briquettes are a technically renewable energy source and their emissions are not anthropogenic greenhouse gases, unlike emissions from traditional coal briquettes, as any carbon released was taken directly from the atmosphere in recent history, not sequestered deep in the earth during the carbon era. . period like coal.

Paper briquettes

Paper briquettes are a by-product of briquettes, which compress the material into the paper is torn into small cylindrical shapes. Briquettes are often sold as an add-on system to an existing disintegrator or rotary knife mill crushing system. The NSA has a maximum particle size regulation for shredded paper material passed through a disintegrator or rotary knife mill, which usually does not exceed 3 mm (1⁄8 inches) square. This means that the material coming out of the disintegrator is a suitable size for compression into paper briquettes, as opposed to a strip-cut shredder which produces long sheets of paper. After being processed through a disintegrator, the paper particles are usually passed through an air system to remove dust and unwanted magnetic material before being sent to the briquettes. The air system may also be responsible for regulating the moisture content in the effluent particles, as briquettes work optimally within a certain humidity range. Studies have shown that the optimal moisture percentage for shredded particles is 18% for paper and 22% for wheat straw. Paper briquettes have many important benefits, many of which minimize the impact of paper waste generated by the shredding system. Some manufacturers claim a volume reduction of up to 90% of waste paper briquettes compared to traditional shredding. Reducing the volume of shredded waste allows it to be transported and stored more efficiently, reducing costs and fuel required for disposal. In addition to the cost savings associated with reducing the volume of waste, paper briquettes are more useful in paper mills for making recycled paper than uncompressed shredded material. Compressed briquettes can also be used as fuel to start a fire or as an insulating material.
