Do wood-based panels made with agro-Industrial Residues provide environmentally benign alternatives? An LCA case study of sugarcane bagasse addition to particle board manufacturing
The International Journal of Life Cycle Assessment, 2014Co-Authors: Diogo Aparecido Lopes Silva, Francisco Antonio Rocco Lahr, Ana Laura Raymundo Pavan, Yovana M. B. Saavedra, Natalia Crespo Mendes, Sabrina Rodrigues Sousa, Roberta Sanches, Aldo Roberto OmettoAbstract:Purpose Sugarcane bagasse is one of the main agro-Industrial Residues which can be used to produce wood-based panels. However, more investigations related to its environmental performance assessment are needed, focusing on questions such as: Does it provide environmental benefits? What are its main environmental impacts? Could it substitute wood as raw material? Accordingly, this paper presents a life cycle assessment (LCA) study of particle board manufactured with sugarcane bagasse Residues. Methods The cradle-to-gate assessment of 1 m^3 of particle board made with sugarcane bagasse (PSB) considered three main subsystems: bagasse generation, bagasse distribution, and PSB production. For the inventory of PSB, dataset from two previous LCA studies related to the conventional particle board production and the ethanol life cycle for the Brazilian context were used. The allocation criterion for the bagasse generation subsystem was 9.08 % (economic base). The potential environmental impact phase was assessed by applying the CML and USEtox methods. PSB was compared with the conventional particle board manufactured in Brazil by the categories of the CML and USETox, and including land use indicators. Finally, two scenarios were analyzed to evaluate the influence of the allocation criteria and the consumption of sugarcane bagasse. Results and discussion All hotspots identified by CML and USETox methods are mainly related to the PSB production subsystem (24–100 % of impacts) due to heavy fuel oil, electricity, and urea-formaldehyde resin supply chain. The bagasse generation subsystem was more relevant to the eutrophication category (75 % of impacts). The bagasse distribution subsystem was not relevant because the impacts on all categories were lower than 1 %. PSB can substitute the conventional particle board mainly because of its lower contribution to abiotic depletion and ecotoxicity. Regarding land use impacts, PSB showed lower values according to all indicators (38–40 % of all impacts), which is explained by the lower demand for land occupation in comparison to that of the traditional particle board. Conclusions PSB can replace the traditional particle board due to its better environmental performance. The analysis of the economic allocation criterion was relevant only for the EP category, being important to reduce diesel and N-based fertilizers use during sugarcane cultivation. Regarding the influence of the sugarcane bagasse consumption, it is suggested that the sugarcane bagasse be mixed up to 75 % during particle board manufacturing so that good quality properties and environmental performance of panels can be provided.

biotechnological potential of agro Industrial Residues i sugarcane bagasse
Bioresource Technology, 2000Co-Authors: Ashok Pandey, Poonam Singh Nee Nigam, Carlos Ricardo Soccol, Vanete Thomaz SoccolAbstract:Abstract Advances in Industrial biotechnology offer potential opportunities for economic utilization of agro-Industrial Residues such as sugarcane bagasse. Sugarcane bagasse, which is a complex material, is the major by-product of the sugar cane industry. It contains about 50% cellulose, 25% hemicellulose and 25% lignin. Due to its abundant availability, it can serve as an ideal substrate for microbial processes for the production of value-added products. Attempts have been made to produce from bagasse substrate protein-enriched animal feed, enzymes, amino acids, organic acids and compounds of pharmaceutical importance, etc. Often, a pre-treatment process has resulted in improved substrate utilization by the microbes. Application of solid-state fermentation technology could be an attractive possibility for such bioconversions. This article reviews the recent developments on processes and products developed for the value addition of sugarcane bagasse through the biotechnological means. Emphasis has been given on more recent developments of the past 8–10 years.

solid state cultivation an efficient method to use toxic agro Industrial Residues
Journal of Basic Microbiology, 2000Co-Authors: Fan Leifa, Ashok Pandey, Carlos Ricardo SoccolAbstract:Studies were carried out to screen twelve strains of Lentinus edodes for their efficiency to grow on toxic agro-Industrial Residues of coffee industry in solid state cultivation (SSC). Based on best mycelial growth (7.57 mm/day) and biomass production (48.78 mg/plate in 12 days at 24 °C) in coffee husk extract medium, a strain, L. edodes LPB 02 was selected for mushroom cultivation in SSC on coffee husk (treated and untreated), coffee spent ground, and a mixed-substrate comprising coffee husk and coffee spent ground (1:1). SSC was carried out under different conditions of moisture and spawn rate. Spawn rate of 10% and moisture level of 55–60% was found suitable for all the substrates. Treatment of the coffee husk with hot water was found useful for its utilization by the fungus. Results showed that there was an increase in the protein content and decrease in the fibre content of the substrates after SSC. Fruiting bodies were obtained from the treated coffee husk, spent ground and mixed-substrate, and the biological efficiency achieved was 85.8, 88.6 and 78.4% for these substrates, respectively. However, no fruiting body was obtained with raw coffee husk was used as the substrate. Results showed that after SSC, there was a decrease of about 27, 40 and 24% in caffeine and about 18, 49 and 12% in tannin contents in the treated coffee husk, coffee spent ground and mixed substrate, respectively. No caffeine or, tannins were found in fruiting body indicating their degradation by the fungal strain.

Application of Tropical Agro-Industrial Residues as Substrate for Solid-state Fermentation Processes
Current Developments in Solid-state Fermentation, 1Co-Authors: Reeta Rani Singhania, Carlos Ricardo Soccol, Ashok PandeyAbstract:In recent years, there has been constant increase in the efforts to utilize agro-Industrial Residues particularly those originating from tropical regions. Advances in Industrial biotechnology offer ample opportunities for its economic utilization. The tropical agro-Industrial Residues are generated in large amounts during the processing and their disposal rather causes several environmental problems. There has been an increasing trend towards more efficient utilization of agro-Industrial Residues such as cassava bagasse, sugar cane bagasse, sugar beet pulp, coffee pulp/husk, oil cakes, apple pomace, etc. in bioprocesses as substrate (carbon source). These are utilised as a potential raw materials in bioprocesses as they provide an excellent substratum for the growth of micro-organism supplying the essential nutrients to them (Pandey and Soccol, 1998; Pandey, 1994; Pandey and Soccol, 2000; Pandey et al., 2000a; 2000b; 2000c; 2000d; Pandey, 1999a; Pandey, 1992). Several processes have been developed that utilise these as raw material for the production of bulk chemicals and value-added fine products such as ethanol, single-cell protein (SCP), mushrooms, enzymes, organic acids, amino acids, biologically active secondary metabolites, etc. Application of agro-Industrial Residues in bioprocesses on the one hand provides alternative substrates, and on other helps in solving pollution problems, which their disposal may otherwise cause. With the advent of biotechnological innovations, mainly in the area of enzyme and fermentation technology, many new avenues have opened for their effective utilization.

Brazilian Archives of Biology and Technology, 2005Co-Authors: Herta Stutz Dalla Santa, Luciana Porto De Souza Vandenberghe, Osmar Roberto Dalla Santa, Débora Brand, Carlos Ricardo SoccolAbstract:The purpose of this work was to produce Beauveria bassiana by Solid-State Fermentation using agro-Industrial Residues and optimizing the cultivation conditions. Refused potatoes, coffee husks and sugar-cane bagasse were tested. The blend of refused potatoes and sugar-cane bagasse (60-40%) with particle size in the range of 0.8-2 mm was used in the fermentation experiments. In Erlenmeyer flasks the best spore production was achieved with the following conditions: incubation temperature 26o C; initial pH 6.0; inoculum concentration 107 spores.g-1.dw and initial moisture 75%. In the column type reactor using forced aeration under the optimized conditions, the maximum production (1.07x1010spores.g-1.dw) was obtained at the 10th day of fermentation. The respirometric analyses of the fermentation showed a strong correlation between fungal growth and spore production.
