“…Most people live in developing-country rural regions [40,41]. About half of households in developing countries still cook and heat their homes using solid fuels with open fires and leaky stoves [42,43]. Many of these people cook using open fires with low thermal efficiency and a high emission rate of air pollutants due to poor burning characteristics [32].…”

The several furniture-making phases, from cutting to processing to polishing, produce a significant volume of sawdust of differing grades. The extraction and disposal of such waste in developing countries with no established or sustainable methods is an increasing problem, frequently posing environmental challenges. Sawdust is one of the most underused wood waste portions, with mounds dispersed around the region, detracting from its visual appeal and causing other ecological concerns. This study investigated potential applications of sawdust as it concerns sustainable development. It sought to employ an extensive systematic literature review to establish that sawdust, which is often a nuisance at sawmills, may be put to beneficial uses. Four cardinal focus areas of this study are (i) energy generation, (ii) environmental protection/pollution containment, (iii) building construction, and (iv) water treatment/supply. Specifically, the study dealt with the feasibility of energy generation from sawdust through sawdust cook stoves, briquetting, and pyrolysis; pollution containment through sawdust-derived adsorbent; affordable building construction through sawdust-based ceiling boards and particles boards; and (iv) water treatment using point of use (PoU) sawdust-clay water filter. Based on over two hundred (200) published papers consulted in this study, it was strongly established that sawdust had found successful wide application in all four thematic areas with strategic connection to the objectives of SDGs 3.0, 6.0, 7.0, 9.0, 11.0 and 12.0. This research believes that emphasis on sustainable sawdust management can help transform the over 1.5 million tonnes of sawdust waste burned or dumped indiscriminately into value-added products each year.

“…At least 50% of people in developing countries still cook and heat their homes using solid fuels (i.e., wood fuel, crop residues, charcoal, and animal dung) in open fires and leaky stoves [1][2][3][4]. Using open fires in household cooking consumes more energy than any other end-use services in developing countries [5].…”

In developing countries, energy demand from biomass has increased due to exponential population growth. This has translated into voluminous quantities of wood being used. The situation is exacerbated by the popular use of inefficient stoves with low thermal insulation, hence contributing to deforestation. In this study, the performance of a cooking stove improved with sawdust as an insulation material was assessed. An insulated fire stove prototype of 26 cm saucepan diameter was designed, constructed, and cast with sawdust and clay in a ratio of 1 : 1 (as the first layer) and sawdust alone as the second layer. The developed stove was tested using a water boiling test to establish its operating performance. The thermal efficiency of the stove was assessed using indigenous wood fuels used in rural Uganda (Senna spectabilis, Pinus caribaea, and Eucalyptus grandis). Computational fluid dynamics was used to simulate the temperature and velocity fields within the combustion chamber and for generating temperature contours of the stove. Obtained results indicated that S. spectabilis had the highest thermal efficiency of 35.5 ± 2.5%, followed by E. grandis (25.7 ± 1.7%) and lastly P. caribaea (19.0 ± 1.2%) in the cold start phase when compared with traditional stoves. The stove remained cold as hot air was restricted to the combustion chamber with decreasing temperature contours toward the outer wall up to the ambient temperature. The velocity flow remained constant as the chamber was colored green throughout due to the shielding of the stove with sawdust as insulation. The heat flux generated indicated that a thick layer of 6 cm or more could ensure good insulation, and this could be further reduced by introducing more sawdust. The designed stove has the potential to reduce biomass consumption and emissions when compared to traditional cookstoves. The inclusion of a chimney draught in the fire stove prototype could reduce smoke and increase thermal efficiency. Further studies should focus on minimizing the thickness of the clay-sawdust (first) layer and increasing the thickness of the sawdust layer to reduce the weight of the fire stove.
