Development of Particleboard from Waste Styrofoam and Sawdust
18 ABDULKAREEM et al: DEVELOPMENT OF PARTICLEBOARD FROM WASTE STYROFOAM AND SAWDUST Development of Particleboard from Waste Styrofoam and Sawdust S. A. Abdulkareem1, S. A. Raji2, A. G. Adeniyi1* 1Chemical Engineering Department, University of Ilorin, Ilorin, Nigeria. 2 Civil Engineering Department, University of Ilorin, Ilorin, Nigeria. ABSTRACT: The use of Plastic Based Resin (PBR) synthesised from waste Styrofoam as binder in the production of particleboard was the focus of this investigation. This study explored the properties of particleboard produced from sawdust wastes and PBR resin synthesized from waste Styrofoam. Three particleboard panels namely C1, C2 and C3 were prepared with 20%, 30%, and 40%, (v/v), respectively. PBR was synthesised via solvolysis of waste Styrofoam in a chosen solvent, and properly mixed with sawdust by simple mechanical stirring, using hand lay-up process in cold pressing to obtain the desired shapes. ASTM D-1037 standard was used to evaluate the physical and mechanical properties of the manufactured particleboards. Density, moisture content (MC), water absorption (WA), thickness swelling (TS), and mechanical properties i.e. modulus of elasticity (MOE) and modulus of rupture (MOR) of C2 and C3 were better than that of C1 particleboard and met the LD-1 requirement of ANSI A208.1. PBR from Styrofoam waste is confirmed as a good substitute for Urea or formaldehyde based resin presently used industrially. The properties of C2 and C3 synthesised are in tandem with the requirements of the ANSI A208.1 standards. KEYWORDS: styrofoam waste, plastic-based resin, particleboard, sawdust waste, curing.

Mechanical Properties of Urea Formaldehyde Particle Board Composite. American Journal of Chemical and Biochemical Engineering . Vol. 2, No. 1, 2018, pp. 10-15. doi: 10.11648/j.ajcbe.20180201.12 Received : May 25, 2018; Accepted : June 7, 2018; Published : July 4, 2018 Abstract: Particle boards were prepared from sawdust and urea-formaldehyde resin (UFR) on compression moulding machine. The particleboards were produced at a compression temperature of 150°C; a pressure of 10tons was applied for 15 minutes. The amount of sawdust was kept constant at 20g while UFR was varied from 30ml, 35ml, 40ml and 45ml respectively. The control sample (CS) was the 50ml UFR without any saw dust. The properties of the particleboards were tested using ASTM methods. The results showed that the properties of the particleboards are a function of the percentage composition of the binder (resin) and the filler (sawdust). The results showed that as the URF content increased from 30ml to 45ml, the mechanical properties increased. -

CFD Based Analysis of Swietenia Mahogani Seed and Its Applications
IAETSD JOURNAL FOR ADVANCED RESEARCH IN APPLIED SCIENCES ISSN NO: 2394-8442 CFD Based Analysis of Swietenia Mahogani Seed and its Applications Titu Wilson*1, Anandu Raj *2, Susan K Thomas#3 * Department of Aeronautical Engineering, Mount Zion College of Engineering, Pathanamthitta, Kerala, INDIA, # Assistant Professor, Department of Aeronautical Engineering, Mount Zion College of Engineering, Pathanamthitta, Kerala, INDIA [email protected] [email protected] [email protected] Abstract— Swietenia Mahogani (Mahogany) seeds shows an extraordinary falling characteristic known as autorotation. The mahogany seeds are equipped with a small wing, which starts to auto rotate within 1 meter after they are detached from the tree. The seeds rotates in its axis centre similar to that of the gyration of propeller about its pivot point. This motion generates lift which slows down the falling speed and provides an additional time to stay afloat. In this paper the flow field around a mahogany seed under free fall condition is analyzed to discover its aerodynamic characteristics and study about its potential use as a wind turbine. Keywords— Autorotation, Axis centre, Gyration, Pivot point, Swietenia Mahagoni, Wind turbine. I. INTRODUCTION Nature is the best fascinating source of creativity and inspiration. Nature can inspire us about systems structures, designs, materials, processes, aesthetics, etc. Biomimetics is the term used to describe the substances, equipment, mechanism, and systems by humans to imitate natural systems and designs, aiming at solving problems by first examining, and then imitating or drawing inspiration from models in nature [1,2,3]. Mahogany seeds are one of the most generally interesting specimens for biological aerodynamic study within nature. -

WHAT DOES CARB MEAN TO MY BUSINESS AS A FABRICATOR? Sharing information with our partners Prepared by July, 2008 INDOOR AIR QUALITY IS A TOP PRIORITY CALIFORNIA ELIMINATES ADDED UREA FORMALDEHYDE This session will provide information on CARB, its January, 2009 launch date with following Phases, and impacts upon fabrication with documentation requirements for the HPL markets. INDOOR AIR QUALITY IS A TOP PRIORITY CALIFORNIA ELIMINATES ADDED UREA FORMALDEHYDE As we begin, it is important to note that: HPL doesn’t contain added formaldehyde. Lamin-Art HPL has been certified by GREENGUARD as a low-emitting product for indoor air quality. The application of HPL to CARB compliant core material with proper adhesives helps to assure air quality for healthy indoor environments. WHAT IS THE CALIFORNIA AIR RESOURCES BOARD (CARB)? One of six agencies within the California Environmental Protection Agency, EPA, the Air Resources Board’s (ARB) mission is to “Promote and protect public health, welfare and ecological resources through the effective and efficient reduction of air pollutants in recognition and consideration of the effects on the economy of the state.” HOW CAN CARB INFLUENCE MY BUSINESS? The state of California has led the U.S. as an early adopter of many environmental and health/safety initiatives. History has shown the U.S. market to quickly follow California. HOW CAN CARB INFLUENCE MY BUSINESS? In 1992 the EPA identified formaldehyde as a probable carcinogen and the state of California named it a toxic air contaminant with no safe level of exposure. HOW CAN CARB INFLUENCE MY BUSINESS? In 2001, the United States Green Building Council, USGBC’s LEED rating system began awarding credit for use of composite wood products with no added urea formaldehyde, setting a high standard an clear signal to the market. -
Oriented Strand Board Industry Development in the South American Region - Main Challenges
Proceedings of the 51st International Convention of Society of Wood Science and Technology November 10-12, 2008 Concepción, CHILE Oriented Strand Board Industry Development in the South American Region - Main Challenges Victor Gaete-Martinez PhD Student University of Maine AEWC Center, Orono ME, USA. BSc, Forestry Science University of Chile [email protected]. Alejandro Bozo Associate Professor University of Chile, Santiago-Chile [email protected] Abstract Unlike North American (N.A.) and European markets, the oriented strand board (OSB) industry is currently in an introductory stage of development in South America (S.A.). Although OSB mills have been operating for more than five years in Chile and more recently in Brazil and Venezuela, the production levels and consumption remain far below those existing in more mature markets. In contrast particleboard and medium density fiberboard (MDF) industries had a very intense and fast development in the past for the same market and even under less favorable conditions. Even other structural wood composites have a more expanded development in the region, i.e. LVL. Although the remarkable structural properties of OSB and potential advantages over other building materials are well known, some factors disallowing a stronger positioning of the product exist. The objective of this research was to analyze the evolution of the OSB industry in the South American region and determine the obstacles and challenges that this industry currently faces. A comparative analysis was carried out between the N.A. and S.A. OSB market evolutions; cultural backgrounds; research and development (R&D) investment and initiatives as well as political and governmental influence. -
Classification of CITES-Listed and Other Neotropical Meliaceae Wood Images Using Convolutional Neural Networks
Ravindran et al. Plant Methods (2018) 14:25 https://doi.org/10.1186/s13007-018-0292-9 Plant Methods METHODOLOGY Open Access Classifcation of CITES-listed and other neotropical Meliaceae wood images using convolutional neural networks Prabu Ravindran1,2, Adriana Costa1,2, Richard Soares1,2 and Alex C. Wiedenhoeft1,2,3,4* Abstract Background: The current state-of-the-art for feld wood identifcation to combat illegal logging relies on experi- enced practitioners using hand lenses, specialized identifcation keys, atlases of woods, and feld manuals. Accumula- tion of this expertise is time-consuming and access to training is relatively rare compared to the international demand for feld wood identifcation. A reliable, consistent and cost efective feld screening method is necessary for efective global scale enforcement of international treaties such as the Convention on the International Trade in Endagered Species (CITES) or national laws (e.g. the US Lacey Act) governing timber trade and imports. Results: We present highly efective computer vision classifcation models, based on deep convolutional neural networks, trained via transfer learning, to identify the woods of 10 neotropical species in the family Meliaceae, includ- ing CITES-listed Swietenia macrophylla, Swietenia mahagoni, Cedrela fssilis, and Cedrela odorata. We build and evaluate models to classify the 10 woods at the species and genus levels, with image-level model accuracy ranging from 87.4 to 97.5%, with the strongest performance by the genus-level model. Misclassifed images are attributed to classes consistent with traditional wood anatomical results, and our species-level accuracy greatly exceeds the resolution of traditional wood identifcation.
