“…While algae have been used as a binding agent, other researchers have used it as the main feedstock after drying to produce briquettes [78]. Marangon, et al [79] proposed the development of microalgae biomass briquetting as a means of achieving more sustainable energy products with less pressure on the environment.…”

The adverse effect of the use of fossil fuels on the environment and public health has given rise to a sustained renewable energy research and development. An important component of global renewable energy mix is the use of loose biomass, including agricultural and forestry residues, to produce solid fuels in the form of briquettes. Briquettes play a significant role in bioenergy mix in developing and developed countries. The production of biomass briquettes often entails the collection, transportation, storage, processing, and compaction of loose biomass that meet specific quality parameters. The densification process often involves the addition of binders to improve the cohesive strength of the briquette material. This paper surveys recent literature from 2012 to 2021 to establish the current state of research on the use of binders in briquette production; and reviews current parameters used in assessing the quality of biomass briquettes with focus on mechanical and handling properties. While a number of quality parameters were identified, their assessment methodologies varied widely in the literature, thus necessitating standardization for comparability purposes. The review also includes factors affecting the wide production and adoption of biomass briquettes in most developing economies and proposes ways of overcoming the bottlenecks.

“…Based on responses that emerged during focus group discussions (FGDs), it became evident that raw materials for briquette production in Tanzania were primarily obtained from two sources: crop wastes and timber factories. Producers of briquettes often take the initiative to collect these materials themselves, re ecting their hands-on involvement in the initial stages of the value chain (Rawat and Kumar, 2022). This practice not only underscores their commitment to sustainability but also offers a direct and cost-effective means of sourcing the necessary ingredients for briquette manufacturing (Asamoah et al, 2016).…”

The reported study highlights the potential for biomass briquettes as a cleaner and more sustainable alternative to traditional fuels like firewood and charcoal in Tanzania. Focus group discussions and key informant meetings were conducted, involving stakeholders from 16 regions of Tanzania's mainland. Rating scales and SWOT analysis were used to analyze the collected information. Our analysis showed that briquette technology can contribute to reducing deforestation, climate change mitigation, and employment generation. However, it also identified various challenges like market incompetency, limited access to technology, community misconceptions about briquettes, and a lack of political support. To mitigate these challenges and promote the briquette sector in Tanzania, the study suggests various interventions, particularly providing technical training and resources to accelerate production and quality assurance and engaging with policymakers to advocate for supportive policies and incentives. Additionally, developing effective marketing and distribution strategies. In conclusion, the study indicates that Tanzania has the potential to advance the biomass briquette sector, which has positive social, ecological and economic impacts. However, addressing these challenges and realizing their potential benefits will require a collaborative and multifaceted approach involving various stakeholders, like government agencies, researchers, development partners, NGOs, and local communities.

“…As a result of lack of access to electricity, majority of people in the developing world rely on traditional biomass as fuel for heating and cooking (Rawat et al, 2022), with charcoal playing an increasingly important role. The production of briquettes from charcoal fines and organic residues has been identified as a viable and economical option to reduce the environmental impact resulting from the disposal of these waste materials (Barasa et al, 2013).…”

Charcoal fines, a waste emanating from charcoal transportation and handling, were utilized in the fabrication of briquettes using tannin-formaldehyde resin as a binder to meet ever expanding energy demand. A collection of four briquette samples were fabricated with binder proportions of 25%, 30%, 35%, and 40%. These briquettes were characterized using Fourier transform infra-red and thermogravimetric analyses techniques. Furthermore, the briquettes were subjected to physical parameters namely bulk density, impact resistance index (IRI), water resistance index (WRI), and water boiling test. The bulk density of the briquettes was 1.153-1.495 g/cm<sup>3</sup>, IRI was 6.79-73.33, and WRI was 99.24-99.29. The briquettes exhibited an ignition time of 5.38-6.21 minutes, boiling time of 19.50-37.20 minutes, burning rate of 3.20-8.70 g/minute, and a specific fuel consumption of 54.70-64.30 g/L. Higher heating value range for the briquettes was 19.76-23.23 MJ/kg and the briquettes with 40% binder showed the best physical qualities with great fuel potential. Therefore, the fabricated briquettes have demonstrated great potential as a source of cleaner and sustainable energy.
