High density polyethylene (HDPE) Plastic Lumber.

This paper is not to persuade the use of either Conventional, or “Green” building materials it is simply a comparison of the pros and cons of your design choices.

Wood has been a standard building material for centuries. Craftsmen, suppliers and manufacturers always want to see more wood used in materials and goods. The high market value of a real wood floors, furniture, accents and finishes will always be a selling point in any big purchase. There is something wood; unlike other materials, brings that warm, rich inviting look no matter the application it has been implicated in. Even with the pride of ownership and demand for high price; Wood is also the highly coveted material of choice in the cooking profession when it comes to choosing utensils. Wood of course is an essential material in manufacturing instruments, wither it be jamming on a guitar or playing a musical-toon on an oboe. Also let us not forget all those number 2 pencils destroyed during ones educational career. Even with all these wonderful applications for wood just mentioned in this paragraph and the many more items wood can and still is used for; still cannot help it over-come its true fate in nature. Wood deteriorates. It cracks, it rots, its splinters, it is prone to mildew and mold, the list goes on. Of course one would argue that not all of these negative aspects of wood pertain to all of said items, sure it depends on where, what and how it is being used. But the majority of Wood applications come from the Architectural field. It is exposed to the elements across the globe in all climates. So when looking at this organic material from an drafting and design standpoint, one could not help to point out that it’s a possible breeding ground for bacteria and a hearty meal for termites and other insects. After a short period of time, your wood lumber looks old and needs replacement. It also should be noted that from an environmental standpoint, wood cannot be recycled, and its production leads to deforestation.
(HDPE) Most plastic lumber products on the market are made from a single resin, polyethylene, which is available in high and low densities (HDPE and LDPE). Some manufacturers are also using polystyrene (PS) and polyvinyl chloride (PVC). Still others rely on a commingled mix of different types of plastics (largely collected from municipal recycling programs). All plastic types (also called plastic resins) currently used for lumber share a common origin in fossil fuels and thus a common set of initial environmental impacts. Many of these types of plastic lumber can come in several colors to fit a desired application and is fast becoming a common building material, just like conventional lumber. Plastic lumber is becoming more popular among businesses and future homebuilders wanting to make a difference where ever they can and build greener projects. Since plastic lumber first started being used for commercial building in 1990, many builders have found out how beneficial this green product is. They realize that plastic lumber does not fade or warp it does not grow structurally unstable over time due to the elements and nature in general and does not attract bugs, such as termites. These are all common problems when building with wooden materials. Plastic lumber is a lot more user friendly as in easy maintenance it does not need to be stained, treated, or painted and can be cleaned with water. Workability is another advantage to plastic lumber. It holds nails and screws more soundly than wood, and it can be bent and formed into shape more easily. But again, just like in the Wood category (HDPE) plastic lumber has a list of disadvantages too. We will start with the most notable one Cost; expect to pay twice the cost of treated wood for most composites, and even more for all-plastic planks. That's often a stopper, even though you'll save on resealing and possible repairs in the long term. Construction problems, the main problem with plastic lumber is that it is not as strong as naturally-occurring wood. Therefore, a lot of problems arise when using the material in real world applications. The contractors must take special precautions when handling it because some are unaware of the difference, hence building process may be delayed. It is essential that the manufacturer supplies instruction for proper handling of the wood. There is also the issue of the chemical make-up of the (HDPE) lumber and over time some of that combination can become toxic. So whether you choose conventional or alternative the product selection process is the same for green products as for standard non-green products. All of the typical considerations for the quality, performance, aesthetics, and cost of a product are explored as usual. Add to this list, green. What are the environmental?
Impacts of the product,
The standard product selection process includes the following steps:
1. Identify material categories.
2. Identify performance criteria.
3. Identify building material options.
4. Gather technical information.
5. Review submitted information for completeness.
6. Evaluate materials

Obviously, some basic understanding is required at each step. You must understand requirements for how a building is put together in order to identify the material categories necessary for a project. Also, you must have a working knowledge of current construction techniques in order to assess building material options and to know what technical information is necessary for proper evaluation. Concrete, for example, has different performance criteria than does waterproofing. Some considerations, such as durability and cost, are common to all material categories, but the expectations for different materials will be different. A building owner may expect the roof to last 10 to 20 years with relatively little maintenance but may anticipate replacing the carpet every 5 to 7 years.
So in a nutshell or a 4 page research paper such as this one choosing a high quality building material is essential, either it be wood, plastic, glass or steel. You will always ask the same questions what is the purpose of said building, how much money can I afford to spend, do I or do I not care about environmental impact and if any how far are you willing to go with your venture. Like I said in the beginning this is not a persuasion paper for green design or conventional design. All materials have their place; this just gives you an idea on 2 different forms of building it is up to you to determine what is best for your personal use.

...CHAPTER 1 SOLID WASTE – TYPES, SOURCES AND PROPERTIES Learning Objectives; At the end of this lesson, students should be able to; 1. define solid waste 2. describe different types of solid wastes 3. recognize different sources of solid wastes 4. understand and state the three physical, chemical and biological properties of solid waste 2 Introduction Solid wastes are the wastes arising from human activities and are normally solid as opposed to liquid or gaseous and are discarded as useless or unwanted. Focused on urban waste (MSW) as opposed to agricultural, mining and industrial wastes. Integrated Solid Waste Management (ISWM) is the term applied to all the activities associated with the management of society's wastes. In medieval times, wastes discarded in the streets led to the breeding of rats and the associated fleas which carried the bubonic plague. The lack of management of solid wastes thus led to the Black Plague which killed half of 14th century Europe. 22 human diseases are associated to improper solid waste management. Solid wastes also have a great potential to pollute the air and water. Mining tailings from gold and silver mines will probably being spilling arsenic into the water supply forever. Materials Flow - The best way to reduce solid wastes is not to create them in the first place. Others methods include: decrease consumption of raw material and increase the rate of recovery of waste materials. Technological advances - Increased use of plastics......

Effects of Processing Temperature, Screw Speed, and Heating Conditions on the Mechanical Properties of Pure Pvc (Polyvinyl Chloride)

...Hypothesis……………………………………………………………………………………33 References…………………………………………………………………………………………………………..33 1| Abstract The effects of the temperature of heating zones and the screw speed of the extruder on the tensile strength of the PVC sheets produced has been analysed in our report. In order to get a brief idea of the possible results, a literature review of some of the previous papers on similar topics was done. We designed our experiment based on CCRD, but due to time constraints and the shortage of raw material we had to use the full factorial method to vary parameters of our experiments. Introduction Polyvinyl chloride, commonly abbreviated PVC, is the third-most widely produced plastic after polyethylene and polypropylene. PVC is used in construction because it is more effective than traditional materials such as copper, iron or wood in pipe and profile applications. Its properties are often modified (it can be made softer and more flexible) by the...

...Chapter 1 INTRODUCTION The world population is living, working, vacationing, increasingly mixing along the coasts, and standing on the front row of the greatest, most extraordinary, plastic waste tide ever faced. Washed out on the coasts in obvious and clearly visible form, the plastic pollution display obviously seen on the beaches is only the preface of the greater story that unfolded further away in the world’s oceans, yet mostly originating from where people stand: the land. In 2008, our global plastic consumption worldwide has been estimated at 260 million tons, and, according to a 2012 report by Global Industry Analysts, plastic consumption is to reach 297.5 million tons by 2015. Plastic is versatile, lightweight, flexible, moisture resistant, strong, and relatively inexpensive. Those are the attractive qualities that lead us, around the world, to such a voracious appetite and over-consumption of plastic goods. However, durable and very slow to degrade, plastic materials that are used in the production of so many products all, ultimately, become waste with staying power. Our tremendous attraction to plastic, coupled with an undeniable behavioral propensity of increasingly over-consuming, discarding, littering and thus polluting, has become a combination of lethal nature. Plastic bags are in use by consumers worldwide since the 1960’s, (Mc Kinley, 2010). These bags are sometimes called single-use bags, referring to carrying items from a store to a home.

Despite its numerous advantages, the potential of biogas technology could not be fully harnessed or tapped as certain constraints are also associated with it. Most common among these are: the large hydraulic retention time of 30–50 days, low gas production in winter, etc. Therefore, efforts are needed to remove its various limitations so as to popularize this technology in the rural areas. Researchers have tried different techniques to enhance gas production. This paper reviews the various techniques, which could be used to enhance the gas production rate from solid substrates.

LEU Additive manufacturing: technology, applications and research needs © Higher Education Press and Springer-Verlag Berlin Heidelberg 2013 Abstract Additive manufacturing (AM) technology has been researched and developed for more than 20 years. Rather than removing materials, AM processes make three-dimensional parts directly from CAD models by adding materials layer by layer, offering the beneficial ability to build parts with geometric and material complexities that could not be produced by subtractive manufacturing processes. Through intensive research over the past two decades, significant progress has been made in the development and commercialization of new and innovative AM processes, as well as numerous practical applications in aerospace, automotive, biomedical, energy and other fields. This paper reviews the main processes, materials and applications of the current AM technology and presents future research needs for this technology. Keywords additive manufacturing (AM), AM processes, AM materials, AM applications 1 Introduction The ASTM F42 Technical Committee defines additive manufacturing (AM) as the “process of joining materials to make objects from three-dimensional (3D) model data, usually layer upon layer, as opposed to subtractive manufacturing methodologies” [1].

...Chapter 01 1.1 Introduction: A storage device may be used to store energy from renewable energy source in DC form which can be converted to AC power by using power inverter. Pulse Width Modulated (PWM) technique may be used to control output rms voltage of the inverter. As the load is variable, the power consumed by the load (PL) may be smaller than the power generated from the renewable energy source (PR). Therefore a Flexible AC Transmission System (FACTS) Controller may be used to supply the additional power (PR – PL) from the renewable energy source to the grid. On the other hand if the power consumed by the load (PL) is greater than the power generated from the renewable energy source (PR) therefore the same FACTS controller may be used to absorb the additional power (PR – PL) from the grid to the load. In this case the FACTS controller must allow bi-directional power flow. If all the active houses are connected to the grid in the same way (proposed way), the active houses that generate more power than the load can be supplied to the active houses that generate less power than the load. Therefore a suitable FACTS controller should be designed in such a way that it can control the power flow in both directions. The idea is illustrated in the following figure. 1.2 Objectives: • Study on different FACTS controllers • Study on different renewable energy sources • Study on......
