Waste Glass Aggregate Concrete Countertop

Concrete floor is one of the most durable materials in the world. It can be made with waste products which help to reduce the consumption of valuable materials. It also can be made from fly ash, slag cement, and silica fume, all waste byproducts from steel mills, power plants and other manufacturing facilities.

Every recycled object endures a different process tailored specifically to it. Made of sand, soda ash, and limestone, glass leads to be one of the easiest materials to recycle. First, people bring the glass to a specific treatment plant. Sorted by color and washed, this crucial step helps

First, concrete durable. Concrete is something that will outlive other products up to three times over (“What Makes…”). In addition to durability, concrete is efficient. Concrete can be made with byproducts from power plants, and other aspects of manufacturing. Concrete is primarily made up limestone, the most abundant material on Earth. Above all of this concrete can be recycled. Concrete can be crushed and recycled into another structure or product, reducing the need to mine the limestone for production. Concrete also allows water to pass through which reduces the chance of flash flooding, erosion, and water table depletion as compared to other materials. This is a major check in the sustainability of concrete; the conservation of soil, landscape and ecosystems. Concrete is a very green option when it comes to building

Handley goes on to tell us how some items are better left not recycled. Items like glass have a very long and hard process it undergoes to get recycled. It is much easier to make

As many items are recyclable and safe to use, we are helping day by day to insure a safer place for everyone around us, including ourselves. Along with the strong push in the green movement recently, we all should notice that more and more products are being made from recycled material. These items can be found anywhere as they are marked with a special recycling symbol. Manufactures are also finding new ways to help create more items that can be used and recycled. These items include paper towels, cardboard boxes, plastic containers, crayons, ink cartridges to even paint. (Schenker) As technology has change dramatically over the years, it has provided us with ways of studying and finding out better ways to use the material.

The Waste Hierarchy, also know as the three R’s, is a plan often referenced to in the context of recycling. Reduce, reuse, and recycle, “The 3Rs are meant to be a hierarchy, in order of importance.”(Wikipedia). This plan has become the base of the EPA’s push to have recycling taken seriously for the past decade. The first, and most important ‘R’, is reduce. It is important to reduce the amount of byproducts that leave your home because it helps cut down on pollution caused by reprocessing the recyclable materials. The next ‘R’ is reuse. Things such as glass bottles can be washed out and reused in their current state. Thus it would be a waste to put a perfectly good glass bottle into a recycling bin. For recyclable byproducts that cannot be reused unless they are reprocessed, it is important to recycle. The next of the three R’s. Some byproducts can be recycled and used for an entirely different purpose.

Recycling is defined as the separation of salvageable items from composite trash. Recycling is a crucial part of environment sustainability. Benefits from proper recycling systems are obvious, as the life of consumer products are extended beyond one use. By replacing a new product with a used product, raw material usage is minimized as well as the intermittent pollution associated with production. In addition, the re-used product is diverted from becoming

Although recycling of Polyvinyl Chloride (PVC) based plastics decrease the amount of these polymers that end up in municipal waste, the cost of recycling these plastics for the producer are an important factor to weigh in to whether they should be recycled or not. PVC is a soft and flexible plastic used to make clear plastic food wrapping, computer cables, and even pipes and parts for plumbing. Because PVC contains numerous toxins, food products using PVC require virgin material for their construction. In general, there are two types of PVC recycling processes, mechanical and feedstock, which include their own respect costs, purposes, and benefits. Although there are a large number of costs for the producer for recycling PVC from the toxicity to the inefficacy of its recycling process, there are many benefits that include reducing the amount of PVC in municipal waste and its usefulness as a recycled product.

Autoclaved aerated concrete (“AAC”) is currently one of the many building products being touted as “green” or “environmentally friendly.” AAC is not a new building material. is a lightweight manufactured building stone. Comprised of all natural raw materials, AAC is used in a wide range of commercial, industrial, and residential applications and has been in use in Europe for over 70 years, the Middle East for the past 40 years, and South America and Australia for approximately 20 years.1 According to one manufacturer, AAC now accounts for over 40% of all construction in the United Kingdom and more than 60% of construction in Germany.

Recycling of construction materials is a practice that is becoming a necessity in the industry. Aside from the legal and environmental reasons for recycling, it is also usually much cheaper to recycle jobsite wastes than it is to dispose of them into our nations landfills. Furthermore, recycling of wastes is also the responsible thing to do, as it has been shown that as much as 8,000 pounds of waste are tossed into a landfill during the construction of a typical 2,000 square foot home. Advancing technology is affording contractors the opportunity to recycle materials that would have previously been disposed of irresponsibly. There are best practices associated with the responsible disposal of construction and demolition wastes, but they vary from state to state, city to city, and even municipality to municipality. Through literature review, I will highlight some of the best practices employed by various cities, as well as new technologies that enable the recycling and reuse of materials to be accomplished more efficiently. I believe that the findings will be beneficial to all parties. Recycling of construction wastes, especially within the public sector such as cities and municipalities, is sometimes a prerequisite just to be considered for a job. Furthermore, many cities now make it a requirement to recycle “X” percent of construction wastes, or are subject to fines and penalties.

1989). Waste minimization in construction industry is significant not only from efficiency point of view, but also, nowadays, concern has been growing about the adverse effect of the waste of building materials on the environment. This kind of waste typically accounts for between 15 and 30% of urban waste, also it is difficult to recycle building materials due to high levels of contamination and a large degree of heterogeneity and often there is insufficient space for its disposal in large cities. (Brooks et al.1994; Bossink and Brouwers 1996; Forsythe and Marsden 1999) Moreover, reduction in availability of future materials energy as well as increasing demands on the transportation system can be the consequences of high levels of construction waste. Wyatt (1978) Considering some building materials and components which use large amounts of non renewable sources of energy, as well as resources that are in danger of depletion, such as timber, sand, and crushed stone (Bossink and Brouwers 1996).

The production of Portland cement is high-energy consumption and produce large amount emission of CO2. Previous research indicates that 0.98kg of CO2 will be created by production of 1kg of Portland cement, including 0.53g from decarbonisation, 0.33g from burning process plus 0.12g from generation of electricity power required. Therefore, for every ton of cement produced, an approximately equal amount of carbon dioxide is relapsed in to atmosphere [2阿三]. The world cement industry contributes 7% of total CO2 emission [3]. This leads to the research of seeking more environmental friendly cements. One of these alternative materials is alkali-activated slag (AAS) cement. Comparing with Ordinary Portland cement (OPC), the AAS has is own advantages. Firstly, it uses ground granulated blast-furnace slag (GGBS) as the binder material of concrete, which is a by-product from industry production. Secondly, AAS cement has low energy cost and low GHGs emissions. Finally, AAS concrete has excellent engineering

Our environment has a lot of problems with waste that we create and it is getting more out of hand each year. Waste is harming wildlife, rivers, plants, and humans. I have come up with a solution to this global problem and reasons why we need it. My solution is to develop eco-friendly/edible silverware.

A preliminary investigation of strength and durability properties of a low-cost concrete-like system made of pH-adjusted fluorogypsum (FG), class C fly ash (FA), and type II Portland cement (PC). A series of compressive strength tests and volumetric expansion measurements were conducted on specimens after 28 days of curing. The experimental results were used to develop response surface models (RSMs). These RSMs can be used to predict accurately compressive strength and volumetric expansion as functions of the relative content, in dry weight, of different components. The RSMs
