Biomass Briquetting Technology for Sustainable Energy Solutions: Innovations in Forest Biomass Utilization
Kamil Roman, Emilia Grzegorzewska
Abstract
This article aims to provide a comprehensive review of the use of logging residues in manufacturing briquettes, and to demonstrate their potential as a renewable energy source. Technical aspects of briquetting are examined, including wood properties, particle size, moisture content, and process temperature. Forest residues, such as branches and treetops, have a high energy potential with calorific values reaching up to 20 MJ∙kg−1 after briquetting. Densifying these residues increases their energy density (achieving up to 1120 kg∙m−3) and reduces waste and greenhouse gas emissions. Briquetting processes were analyzed economically and environmentally, with studies showing that production costs can be reduced by 25% when using locally sourced residues. This review recommends optimizing production processes to improve briquette durability and quality. Future research directions focused on developing cost-effective briquetting technologies tailored for small- and medium-sized businesses are identified in the study. Rural and economically disadvantaged regions could benefit from these advancements in briquetting. This paper advocates improved collaboration with international organizations to standardize briquette quality, promoting market acceptance and trade. Technology such as briquetting has the potential to advance renewable energy systems and achieve global climate goals.
