    The adverse effects of the combustion of fossil fuels on humanity and the environment have made it vital to discover eco-friendly, sustainable, and renewable energy alternatives. Globally, there exists loose biomass, which is agricultural and cultural waste that can be utilised to produce briquettes, a type of solid fuel. Briquettes have played a significant role in the energy generation economies of both developing and developed nations. The production of briquettes involves a series of activities, including collection, transportation, storage, processing, and densification of the feedstock to meet predetermined quality parameters. Rice husk, corn stalk, wheat straw, cassava stalk, groundnut shell, olive husk, palm kernel shell and coconut shell are among the feedstocks for briquettes. In order to increase the cohesive strength of the briquettes, binders are incorporated during the densification process. This study aims to investigate the current state of research regarding the utilisation of biomass-derived briquettes as a viable substitute for traditional fuels. To achieve this objective, a comprehensive analysis of recent literature published between 2017 and 2023 is conducted. This study encompasses essential subtopics, including the accessibility of biomass, the selection of binders, the parameters of the briquette process, and the equipment used for briquetting.

    Nigerian Biomass for Bioenergy Applications: A Review on the Potential and Challenges
    (Journal of Renewable Materials, 2023-10-24) Adekunle Akanni Adeleke ; Petrus Nzerem; Ayuba Salihu ; Asmau M. Yahya; Peter Pelumi Ikubanni; Ikechuckwu Okafor; Stephen S. Emmanuel; Adebayo Isaac Olosho; Ademidun A. Adesibikan
    Nigeria, often referred to as “the giant of Africa,” boasts a sizable population, a thriving economy, and abundant energy resources. Nevertheless, Nigeria has yet to fully harness its renewable energy potential, despite its enormous capacity in this field. The goal of this review paper is to thoroughly examine the difficulties and untapped opportunities in utilizing biomass for bioenergy production in Nigeria. Notably, Nigeria generates substantial volumes of biomass annually, primarily in the form of agricultural waste, which is often either discarded or burned inefficiently, resulting in significant ecological and environmental damage. Therefore, an efficient approach to reducing pollution and transforming waste into wealth involves converting these biomass resources into energy. This work critically examines the status of biomass utilization for energy applications in Nigeria and highlights the bottlenecks that impede its widespread adoption. The review emphasizes the economic and ecological advantages of biomass utilization over traditional waste treatment methods. Additionally, it underscores the appeal of biomass as an industrial fuel source, particularly considering the current high cost of fossil fuels in contemporary Nigeria. Relevant literature on biomass, energy, agricultural waste, fossil fuel, and calorific value in the context of Nigeria was reviewed by utilizing a thorough search technique in key scientific databases. The analysis did not include any non-English publications. The findings of this research provide valuable insights into the challenges faced in maximizing Nigeria’s biomass potential and offer strategic recommendations to promote the use of biomass for bioenergy development. This review paper will assist a wide range of local and international readers, as well as industries interested in green and bioenergy, in making informed decisions regarding the most suitable types of biomass for biofuel production.
