ArticleAn innovative approach of developing agro-industrial waste to biofuel value chain to avoid charcoal driven deforestation in Kenya
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.We present an innovative value chain on upscaling and commercial production of carbonized bio- briquettes from agro-industrial waste (mainly a sugarcane bagasse), that aims at substituting a forest-based charcoal for household consumption and thus reduce deforestation. We demonstrate the three main pillars of the value-chain: (1). Empowering and capacity building of members of the cooperatives (mainly women), through developing technical skills, using and maintaining technologies and tools, ergonomics and safety, businesses, and marketing. (2). Innovative locally built biowaste to biofuel conversion technologies. This are technologies for raw material (biowaste) preparation (transport, drying and storage), locally developing carbonization kilns of high efficiency and commercial volume, biochar production, selection of bio-based binders, local fabrication of briquetting machines, production of briquettes, drying and storage of briquettes. This section demonstrates (using videos and pictures) on how a daily briquettes production of 3-tonnes is achieved, with briquette qualities comparable to that of wood-based charcoal. We also demonstrate production of custom-made cookstoves for briquettes by modifying existing local cookstoves. Further, we demonstrate the amount of avoided deforestation through such innovative local approaches. (3). Business and market development: This aims at bringing green-jobs to villages in sustainable supply, distribution, and sales of clean locally produced bio-briquettes. The program enables capacity building of members of the cooperatives in business and marketing, building partnership with key market segments and cooperation with private sector such as distributors, consumers, lenders, and banks. The complete value-chain is a result of a successful development and partnership program (2018-2021) supported by the government of Norway that involved Kenyan national institutions, local community cooperatives and international partners.

DocumentEco products: An economic alternative for the reuse of furniture solid waste
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Data and information from the furniture industry in Brazil provided by research institutions and representatives of the productive sector (ABIMÓVEL; CNI; SEBRAE; ABNT) demonstrate the enormous volume of solid waste generated, contrasting with the growing popular interest in products from companies committed to environmental issues. In this context, according to Nahuz (2005) less than 5% of Brazilian furniture companies had environmental conservation policies and/or did not have waste management programs integrated into the sector.In this context, the main objective of this study was to survey the direct fixed costs of producing objects, in the perspective of reusing these wastes and was carried out in the production environments of the Furniture Production Laboratory (LPM) of the Samambaia Campus of the Federal Institute of Brasília and the company USO Atelier, a carpentry shop also located in Brasília.

DocumentIsolation of DNA from preserved woods for identification of wood species through genetic analysis regardless of the age of wood production
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Species identification of wood provides important information for archaeology, restoration of cultural assets, preventing illegal logging, and more. Wood species are usually identified based on their anatomical features with the use of a microscope. However, this method may not be able to distinguish between anatomically similar species or subspecies. To overcome this problem, wood species need to be identified at the molecular level using DNA sequencing. However, unlike living plant cells, wood is difficult to pulverize using a mortar, and DNA extraction from dried wood is challenging. To solve these problems, we propose a pretreatment method in which wood is pulverized using 60-grit sandpaper and hydrated with water for 2 days. Using this method, we were able to stably amplify the rpoB gene from the extracted DNA of Pinus rigida. In addition, sequence analysis of the rpoB gene revealed six single nucleotide polymorphisms (SNPs), which classified the rpoB sequences in the genus Pinus into five groups. Our data indicate that although these SNPs were not suitable for species identification, they can potentially be used to determine the origin of different wood subspecies or individual samples of wood.
