Coco Lumber Sawdust
MushroomPart II. Oyster Growers Mushrooms’ Handbook 1 Chapter 5. Substrate 91 Oyster Mushroom Cultivation Part II. Oyster Mushrooms Chapter 5 Substrate COCO LUMBER SAWDUST J. Christopher D. Custodio Bataan State College, the Philippines Oyster Mushrooms (Pleurotus spp.) are saprophytic as they obtain there nutrients by decomposing various agricultural by-products. This mushroom has been cultivated worldwide because of its taste and low maintenance technology. There are different substrates that have already been identified that can be utilized for the cultivation of oyster mushroom. The possible substrates include rice straw, coffee pulps, sawdust, and even paper. Most of these are types of low-value lignocellulosic wastes that are primarily derived from agricultural practices or the agro-industry. (J.A. Buswell et. al., 1996) The bioconversion of these wastes is one reason why the cultivation of edible mushrooms is an appropriate practice for a society that depends on its agriculture. In the early 1990s, ‘coco lumber’ was given a great attention in the province as a substitute for hardwood. Sawmills producing lumber from coconut trees bloomed in reaction to the increasing demand for this low cost constructional material. Though beginners in mushroom cultivation are usually persuaded not to use sawdust from softwoods, sawdust from coco lumber (Fig. 1) is another possible substrate for P. ostreatus and has shown great results. Growers living near a coco lumber sawmill can make use of this waste product in order to start their own cultivation of oyster mushroom species. Figure 1. Coco lumber sawdust Coco Lumber Sawdust as a Substrate of Oyster Mushroom Oyster mushroom is one example of edible mushrooms that can utilize lignocellulosic materials as a substrate. -

Environmental Considerations of Treated Wood National Park Service – Pacific West Region
Environmental Considerations of Treated Wood National Park Service – Pacific West Region Overview In support of the mission of the National Park Service, making wise decisions about using wood treatments will help protect the natural areas and biodiversity of our parks, and the health of our employees. Preservative-treated wood’s most important benefit is its resistance to water, fungal, and insect damage. Extending the life of wood products reduces the demands on forests for replacement lumber and reduces maintenance and replacement costs. Historic wooden structures that must be repaired with compatible materials or replaced with in-kind materials make durability even more important. Treated woods are nearly impervious to rot and insects, making them good for outdoor use. Wood treated with chromated copper arsenate (CCA) poses certain environmental and health risks, including the leaching of chemicals such as arsenic and chromium into the environment and workers’ risk of exposure to hazardous chemicals. Disposal of treated wood also proves to be an issue, particularly disposal by incineration. Due to these concerns, manufacturers of treated wood and the EPA reached an agreement to end the sale of CCA-treated wood for most lumber products, effective January 1, 2004. The following offers less-toxic alternatives to CCA, handling and use precautions, and other recommendations when considering using treated wood. Due to the toxicity and potential effects on health and the environment, the Presidio Trust implemented a policy on the use of pressure treated lumber. Standard operating procedure now prohibits the use of CCA, ACZA, CZC, ACC, and Pentachlorophenol. All dimensional lumber is now treated with ACQ as an alternative. -

TECO Design and Application Guide Is Divided Into Four Sections
Structural Design and Plywood Application Guide INTRODUCTION Plywood as we know it has been produced since early in the 20th century. It has been in widespread use as sheathing in residential and commercial construction for well over 50 years and has developed a reputation as a premium panel product for both commodity and specialty applications. Structural plywood products give architects, engineers, designers, and builders a broad array of choices for use as subfloors, combination floors (i.e. subfloor and underlayment), wall and roof sheathing. Besides the very important function of supporting, resisting and transferring loads to the main force resisting elements of the building, plywood panels provide an excellent base for many types of finished flooring and provide a flat, solid base upon which the exterior wall cladding and roofing can be applied. This TECO Design and Application Guide is divided into four sections. Section 1 identifies some of the basics in selecting, handling, and storing plywood. Section 2 provides specific details regarding the application of plywood in single or multilayer floor systems, while Section 3 provides similar information for plywood used as wall and roof sheathing. Section 4 provides information on various performance issues concerning plywood. The information provided in this guide is based on standard industry practice. Users of structural-use panels should always consult the local building code and information provided by the panel manufacturer for more specific requirements and recommendations. -

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress
Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress September 16, 2021 Congressional Research Service https://crsreports.congress.gov RL32665 Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress Summary The current and planned size and composition of the Navy, the annual rate of Navy ship procurement, the prospective affordability of the Navy’s shipbuilding plans, and the capacity of the U.S. shipbuilding industry to execute the Navy’s shipbuilding plans have been oversight matters for the congressional defense committees for many years. In December 2016, the Navy released a force-structure goal that calls for achieving and maintaining a fleet of 355 ships of certain types and numbers. The 355-ship goal was made U.S. policy by Section 1025 of the FY2018 National Defense Authorization Act (H.R. 2810/P.L. 115- 91 of December 12, 2017). The Navy and the Department of Defense (DOD) have been working since 2019 to develop a successor for the 355-ship force-level goal. The new goal is expected to introduce a new, more distributed fleet architecture featuring a smaller proportion of larger ships, a larger proportion of smaller ships, and a new third tier of large unmanned vehicles (UVs). On June 17, 2021, the Navy released a long-range Navy shipbuilding document that presents the Biden Administration’s emerging successor to the 355-ship force-level goal. The document calls for a Navy with a more distributed fleet architecture, including 321 to 372 manned ships and 77 to 140 large UVs. A September 2021 Congressional Budget Office (CBO) report estimates that the fleet envisioned in the document would cost an average of between $25.3 billion and $32.7 billion per year in constant FY2021 dollars to procure. -
