environmental performance assessment of the melamine urea formaldehyde muf resin manufacture a case study in brazil
Journal of Cleaner Production, 2015Co-Authors: Diogo Aparecido Lopes Silva, Francisco Antonio Rocco Lahr, Luciano Donizeti Varanda, Andre Luis Christoforo, Aldo Roberto OmettoAbstract:Abstract Melamine-urea-formaldehyde (MUF) resin is commonly used in the production of Wood-Based Panels. It can replace urea-formaldehyde (UF) resin particularly to improve wood panel properties under high humidity conditions. This paper presents a life cycle assessment (LCA) study of the production of MUF resin through a case study conducted in Brazil. The assessment of 1 kg of MUF resin included two main stages: raw material supply and MUF resin manufacturing. A detailed inventory of MUF resin was obtained from technical visits to a Brazilian producer (foreground system), as well as from literature reviews (mainly background systems). The potential environmental impact assessment phase was assessed by applying two methods and seven impact categories: CML (abiotic depletion, acidification, global warming, eutrophication and photochemical oxidation) and USEtox (ecotoxicity and human toxicity). The raw material supply stage was responsible for most of the impacts, except for the toxicological impact categories. Nearly all of the raw material supply hotspots are related to the production of melamine (9–61% of impacts) and urea (3–72% of impacts). The MUF manufacturing stage was significantly more important for ecotoxicity (84% of impacts) and human toxicity (72% of impacts) due to local formaldehyde emissions. Improvement scenarios were developed and the addition of up to 10% of melamine was suggested for the production of MUF resins. MUF resin was compared with UF resin and the results showed that MUF can replace UF resin because of its lower contribution to photochemical oxidation, ecotoxicity and human toxicity.

Accordingly, this paper presents a life cycle assessment (LCA) study of particle board manufactured with sugarcane bagasse residues. The cradle-to-gate assessment of 1 m3 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. 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. 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.

wood based composite made of wood waste and epoxy based ink waste as adhesive a cleaner production alternative
Journal of Cleaner Production, 2018Co-Authors: Amos Magalhaes De Souza, Diogo Aparecido Lopes Silva, Andre Luis Christoforo, Maria Fatima Do Nascimento, Diego Henrique De Almeida, Tiago Hendrigo De Almeida, Francisco Antonio Rocco LahrAbstract:Abstract The search for materials made from renewable sources and free from toxic substances is a global trend towards a cleaner production, and this can be extended to the development of Wood-Based Panels. World production of Wood-Based Panels in 2014 was 388 million cubic meters, which represents an increase of 34% compared to 2010. However, the industrial sector of Wood-Based Panels has been facing some gaps and challenges regarding the toxic emissions coming from conventional adhesives applied to the manufacture of Panels. Faced with these problems, the aim of this study was to assess the technical feasibility and environmental aspects of manufacturing a particleboard made with wood waste and epoxy based ink-waste as adhesive. To this end, the particleboard reinforcement phase was made of particles of wood waste of Pinus sp. and Teak (Tectona grandis) species, while residual ink resin-based epoxy was used as alternative adhesive to reduce demand for urea formaldehyde resin. Particleboards were manufactured and tested by varying some production parameters, namely: low, medium and high-density panel classifications; 20, 30 and 40% epoxy resin content; and mixture of Pinus and Teak wood waste particles from 0, 25, 50, 75, 100%. Physical-mechanical performance of the manufactured particleboards were evaluated according to ABNT NBR 14810 (2013) and ANSI A208.1 (2009) Standard Codes. Statistical analyzes based on Analysis of variance (ANOVA) were used to test the influence of each individual factor (density, adhesive percentage and fraction of Pinus/Teak particles) and their interactions under the physical-mechanical properties. Results showed a satisfactory performance in terms of physical and mechanical properties for treatments with high density (up to 0.80 g/cm³), 30–40% epoxy based ink-waste adhesive and 50–100% Teak wood particles. In most of the cases, the evaluated properties were superior to the compared requirements available at Standard Codes. Finally, it was developed an environmental performance of the particleboards based on a simplified Life Cycle Assessment (LCA) method, and results highlighted some positive environmental aspects as well as social-economic benefits, especially for suppliers of wood waste and resin epoxy residues, and also due to minimization of air releases of free formaldehyde and energy consumption in the production of Panels.

Flat-Pressed Wood Plastic Composite as an Alternative to Conventional Wood-Based Panels
2020Co-Authors: Nadir Ayrilmis, Songklod JarusombutiAbstract:ABSTRACT This study evaluated physical and mechanical properties of the wood plastic composite Panels made using dry-blended rubberwood fiber-polypropylene (PP) powder formulations using a conventional flat-press process under laboratory conditions. Three levels of the rubberwood fibers (Hevea brasiliensis), 40%, 50%, and 60% based on the composition by weight, were mixed with the PP powder without and with 3% (based on weight) maleic anhydride grafted PP (MAPP) as a coupling agent. Water resistance of the Panels was negatively influenced by the increasing wood fiber content. Maximum value of the modulus of rupture of the Panels was reached at 50% fiber content and then decreased as the fiber content reached 60%. The modulus of elasticity the Panels increased with the increase in fiber content from 40 to 60%. Internal bond strength and screw withdrawal resistance declined with the increase in fiber content from 40 to 60%. Formulations with MAPP were found to have higher strength and better water resistance

formaldehyde emission and vocs from lvls produced with three grades of urea formaldehyde resin modified with nanocellulose
Building and Environment, 2016Co-Authors: Nadir Ayrilmis, Youngkyu Lee, Jin Heon Kwon, Taehyung Han, Hyunjoong KimAbstract:Abstract Three grades of liquid urea-formaldehyde (UF) resins with different formaldehyde emission (HCHO) levels such as super E0 (SE0), E0 and E1 were modified by adding different amounts of microfibrillated cellulose (MFC, 5 wt%). The laminated veneer lumbers (LVLs) were produced from the unmodified and modified SE0, E0, and E1 grade resins. The total volatile organic compounds (TVOC) and HCHO of the LVLs were determined at 25 °C, 35 °C, and 45 °C for 30 min using a thermal extractor. The highest VOC emitted from the LVLs was found to be toluene, followed by xylene, benzene, and ethyl-benzene, respectively. Styrene, however, was not detected at all in any of the systems. The incorporation of the MFC into the SE0 up to 30 wt% significantly decreased the formaldehyde emission from of the UF resin while this not observed for E0 and E1 grade resins. The TVOC from the LVLs considerably decreased with increasing MFC content at 25 °C and 35 °C. The use of MFC in the UF resin can be environmentally friendly solution for reducing the TVOC from the Wood-Based Panels, in particular for indoor furniture at 25 °C and 35 °C.

utilization of pine pinus pinea l cone in manufacture of wood based composite
Forest Ecology and Management, 2009Co-Authors: Nadir Ayrilmis, Umit Buyuksari, Erkan Avci, Enus KocAbstract:Abstract Physical and mechanical properties of medium density fiberboards (MDF) made from various mixtures of wood fibers and stone pine ( Pinus pinea L.) cones were evaluated using European standards. MDF Panels were manufactured using standardized procedures that simulated industrial production at the laboratory. Six panel types were made from mixtures of wood fiber/cone flour, 100/0, 90/10, 80/20, 70/30, 60/40, and 50/50 percents, respectively. Addition of the cone flour into the MDF significantly reduced formaldehyde emission from the panel. In addition, the addition of 10% cone flour also improved water resistance of the MDF Panels made using urea–formaldehyde (UF) resin. However, further addition of the cone flour into the panel negatively influenced their water resistance. Flexural properties and internal bond strength decreased with the increase of cone flour content in the panel. The UF resin is the main source of formaldehyde emission from the UF-bonded Wood-Based Panels. Depending on addition of the cone flour in the Panels, the formaldehyde emission values ranged from 2.6% to 55.3% lower than the Panels made from 100% wood fiber. Based on the findings obtained from this study, pine cone can be used as a renewable biological formaldehyde catcher as an alternative to the traditional formaldehyde catchers for E1 Class MDF manufacture.
