“…Many Ghanaian households, particularly in rural areas, face intensified risks of hospital-acquired pneumonia (HAP) resulting from the extensive use of firewood and charcoal for cooking . HAP results in the loss of 502,000 disability-adjusted life years (DALYs) and 18,000 premature deaths annually and contributes to 2.2% of Ghana’s national burden of diseases associated with solid fuel use . Recent projections indicate that household demand for wood and charcoal is expected to rise, constituting about one-third of the total energy demand by 2030 .…”

The increasing global demand for energy drives extensive consumption of fossil fuels, resulting in excessive CO 2 and greenhouse gas emissions which contribute to environmental pollution and climate change. Projections indicate a 19% increase in energy demand in Ghana and worldwide by 2040, accompanied by a 1.9% rise in CO 2 emissions annually. To address this issue, imperative research and development into alternative fuels are crucial for reducing the reliance on fossil fuels and mitigating their adverse environmental impacts. Exploring renewable resources, devoid of harmful effects on health and the environment, is very essential. The development and utilization of pellet fuels from diverse biomass sources present both opportunities and hurdles faced by current technologies. Pellets have an impressive breakage rate below 1.5%−2.0%, dry base moisture content below 10%−15%, carbon content below 0.5%, nitrogen and sulfur contents both below 0.07%, and ash content below 1.5%, which make them burn at an exceptional combustion efficiency. Biomass pellet fuels have their environmental protection emissions conform to the emission standards set for gas-fired boilers. The standardized nature of biomass pellets makes them more marketable and accessible for use in various energy applications, and they can be made from all kinds of biomass residues or wastes. After the densification process, it solves the environmental pollution of scraps, and it is capable of replacing coal for combustion in boilers and other combustion devices. This paper reviews the local systems for producing and utilizing pellet fuels made from low-density biomass residues in Ghana. The paper critically analyzes the potentials of various biomass resources in Ghana and their utilizations and the major biomass conversion techniques commonly used in Ghana. Furthermore, the paper presents diverse features of the pellet fuel production process comprising biomass feedstock processing before pelletizing, parameters influencing the pelletization process to produce quality pellet fuels, and the properties of pellet fuels in Ghana. The latter part of this paper reviews the major applications of pellet fuels and their economic feasibility in Ghana.

“…Additionally, pressed cylindrical particles (pellets) made from wood sawdust have been burned in household stoves more and more recently for cooking or heating reasons [11]. Once more, electricity is generated, and the need for electricity is satisfied with less air pollution and more domestic resources by burning wood and coal in thermal power plants.…”

Liquid products obtained by the fast pyrolysis process applied to biomass can be used as chemical raw materials and liquid fuels. In this study, tea bush, walnut shell, and pine cone samples selected as biomass samples were obtained from Trabzon and Rize provinces in the Eastern Black Sea Region and used. When considered in terms of our region, the available biomass waste samples are easy to access and have a high potential in quantity. To employ them in the experimental investigation, these biomass samples were first ground, sieved to a particle size of 1.0 mm, and mixed. A fast pyrolysis process was applied to this obtained biomass mixture in a fixed-bed pyrolysis reactor. The effects of temperature, heating rate, and nitrogen flow rate on the product yields of the fast pyrolysis technique used on the biomass mixture are examined. A constant particle size of 1.0 mm, temperatures of 300, 400, 500, 600, and 750 °C, heating rates of 100, 250, 400, and 600 °C.min−1, and flow rates of 50, 100, 200, and 300 cm3.min−1 were used in tests on fast pyrolysis. The studies showed the 500 °C pyrolysis temperature, 100 °C min−1 heating rate, and 50 cm3.min−1 nitrogen flow rate gave the maximum liquid product yield. The liquid product generated under the most compelling circumstances is analyzed to determine moisture, calorific value, fixed carbon, ash, raw coke, and volatile matter. Additionally, the crude bio-oil heating value, measured at 5900 cal/g and produced under the most favorable pyrolysis circumstances, rose by around 40% compared to its starting material. The liquid product obtained from rapid pyrolysis experiments can be used as liquid fuel. The evaluation of the potential of chemical raw materials can be a subject of research in a different discipline since there are many chemical raw materials (glycerine, furfurals, cellulose and derivatives, carbonaceous materials, and so forth) in fast pyrolysis liquids.
