The properties of the Empty Fruit Bunch (EFB) charcoal briquettes are comparable to those of commercial sawdust charcoal briquettes. With the increasing global interest in renewable energy fuels, and the decreasing sawdust supply, EFB fibre is a viable alternative raw material for the production of biomass charcoal briquettes.
Pelleting reduces moisture content and increases density, making for reduced shipping logistics and higher energy density.
During carbonisation, the EFB is heated in a sealed reactor vessel, isolated from oxygen in the air which would otherwise allow it to combust down to ash.
Carbonisation thermally decomposes EFB into a variety of substances, the main one of which is charcoal, a black porous solid consisting mainly of elemental carbon.
Charcoal products can also be produced from biomass sources such as wood, woody agricultural products, the biogenic fraction of municipal wastes, nut shells, etc. and the liquid and gaseous fractions obtained from biomass are a valuable fuel source. And, after applying an additional activation step, the solid fraction (charcoal) has the recovery potential of carbon black or as carbon adsorbent.
Charcoal is produced by slow heating wood (carbonization) in airtight ovens or retorts, in chambers with various gases, or in kilns supplied with limited and controlled amounts of air. Charcoal has the potential to improve soil properties, crop productivity, and carbon sequestration in soil.
The optimum temperature range for the production of the pyrolysis products is between 625 and 775 K but the charcoal yield decreased gradually from 43.5 to 31.0% for walnut shells and from 38.3 to 25.4% for spruce wood with an increase of temperature from 550 to 1150 K.
Charcoal briquettes that are sold on the commercial market are typically made from a binder and a filler.
Biomass energy provides a clean fuel to help preserve our environment. World population is constantly increasing and this results in increased waste must be carefully managed. A lot of the waste ends up in rivers and other water course, something that is not only a danger to the environement but a thoughtless waste of resources.
Biomass can be sourced from agriculture, forestry,fisheries, aquaculture, algae and the waste generated by humans populations. The evidence points to biomass being amongst the most efficient source of renewable energy available.
