“…Wood carbonization dates back thousands of years. Also called slow pyrolysis, this process consists of thermal decomposition in which wood is subjected to a heating rate under a low-content or oxygen-free atmosphere, so the raw material does not burn but only decomposes by the action of the heat, in times ranging from hours to days [5,6]. Through the carbonization of wood, agricultural waste products of other lignocellulosic materials are processed, yielding three types of products, as follows: solids…”

Charcoal is one of the most essential energy sources in the world and is used mainly for domestic and industrial purposes. Brazilian charcoal production occurs in rudimentary masonry kilns without concern for process safety or energy waste. This work aimed to develop a mini carbonization system of three kilns coupled to a vertical smoke burner for optimized and environmentally correct charcoal and wood vinegar (WV) production on small farms. The project was divided into three parts for dimensioning: the three-kiln set, the WV condensing device, and the smoke burner. The condenser was designed following the procedures from the standards of TEMA (Tubular Exchangers Manufacturers Association); ASME (Society of Mechanical Engineers of the United States) Section VIII, Division 1; and the NR-13 (Regulatory Standard) of ABNT (Brazilian Association of Technical Standards). In contrast to the current scenario, in which primitive carbonization technologies are still employed, bringing about low charcoal yields and significant pollution release, the use of a mini-kiln that allows charcoal production and wood vinegar recovery combined with pollutant smoke burning is an interesting eco-friendly solution. Thus, the mini-kiln model presented here brings a low cost and environmental safety to the charcoal production chain, reaching sustainability parameters and offering higher income opportunities to small producers.

The wood carbonization is made at an enclosed environment with controlled addition of atmospheric air producing, besides charcoal, other coproducts such as condensable and non-condensable gases. These gases, which represent 70% of the dry wood mass, are released into the atmosphere, decreasing air quality and producing environmental and social impacts. In this context, it is necessary to develop technologies capable to convert these gases into usable products or transform them into heat and power. The incineration of gases from charcoal kilns opens new opportunities of business because the energy provided by burners can be utilized for drying the wood to be introduced into the kilns and for generation of electricity. On the other hand, condensable gases can also be used on a route to recover and purify the pyroligneous acid. Pyroligneous acid finds application in diverse areas, as antiseptic, antioxidant, antimicrobial, anti-inflammatory, herbicide, pesticide, plant growth enhancer, antitermitic activities; is a source for valuable chemicals; and provides smoked flavor and aroma for food. The main objective of this review is to explore the potential use of wood pyrolysis coproducts, aiming to subsidize and to encourage the technological development of equipment for use of these coproducts. This paper highlights the potential benefits arising from pyroligneous acid application and discusses the charcoal cogeneration technologies.
