Recyclable materials - Which building materials are available for reuse?
The construction industry is responsible for 75% of the use of natural resources from the earth, while recyclable materials such as stone, sand, iron and many others were promoted in large quantities to provide these markets. In addition, building sites themselves cause huge amounts of waste, be it through construction work, construction work or renovations. In Brazil, for example, construction waste can form between 50% and 70% of the total mass of sediment waste. These wastes often land on landfills, rather than being disposed of properly, which was excessive for municipal wastewater systems and provided informal landfills. In this post, we provide materials for this purpose that are recyclable materials for reuse.
Recyclable materials from the construction industry
With greater care, this waste could still have tremendous potential for reuse. If specialists provide the appropriate destinations and process them properly, they can replace recycled materials obtained from landfills. Sometimes these are the new parts, while maintaining a quality comparable to traditional building materials in general.
In recycling, we can then recycle disposable recyclable materials to add them back to the production cycle. This process reduces the consumption of raw materials, reduces the volume of waste and can create workplaces for thousands of people. To start the process, an efficient separation and collection system is essential. Although the classifications in each country are different, there are generally two main classes. The first group includes concrete, ceramics, stone and mortar, which make up the largest part of the construction site. The other class includes wood, metal, glass, plastics, plaster and more. Here are frequent recyclable materials and any uses that can be fulfilled.
The building steel can be recovered from the combination of iron ore and coal, which are heated in a stove. In other cases, this is followed by recycling of scrap, which can be generated in one electrode. The Recycling of Steel is even back on the Roman Empire, as soldiers gathered in protective graves to retrieve war devices, to restore new weapons. In fact, we can transform steel without our loss of quality endlessly into new objects.
During the process, we can also reduce electricity consumption by 80%, thereby reducing the environmental impact on the environment. Somite also completely disrupts the raw material extraction. The movement for steel concrete, wires, nails and some metal profiles can restore the industry in general from alt-metal.
Concrete for recyclable materials
Through the Recycling of Concrete, we can reuse the building material and reduce the construction costs accordingly. In the re-use of hardened concrete, engineers use a special crusher that produces so-called recyclable excipients. Until recently, recycled concrete will only be used as a substitute. Tests have shown, however, that concrete aggregates can withstand the right technology structural elements from 30 to 40 MPa (megapascals). In addition, it is also important that recycled aggregates between ten and fifteen percent less per unit volume than fresh concrete, had less weight per cubic meter and therefore lower material, transport and total project costs.
The use of "Altholz" has become very popular. Hardwoods can hold hundreds of years if we store them properly. These building materials can be used as large components or as slats for the manufacture of other artefacts such as boxes, pallets or supports for various purposes. But safer and cheaper wood can be recycled, especially as a raw material for the plate industry.
The most frequent use of recycled wood is found today in the complete grinding of wood and in the manufacture of MDF boards for the manufacture of wood materials. Another possibility, if none of the above processes can be used, is to dispose of wood waste for biomass production by burning in industrial furnaces.
The recycling of gypsum in construction is possible, but in case of accidental disposal can be released flammable and highly toxic sulfur, which pollutes the soil and the groundwater. Recycled plaster still retains suitable processing which has the same physical and mechanical properties as recyclable plaster at relatively low cost.
Expanded polystyrene or EPS is a material that can be recycled with good results and suitably environmentally friendly. The final product transforms itself into a raw material for the manufacture of new plastic products, if we reduce and compact them. The construction industry could use this for paint or even paint, which could be of great significance to the environment.
Although glass bottles and containers are highly recyclable, the recycling of window glass is associated with a number of additional complications. Because of its different chemical composition and melting temperature it cannot be recycled together with other glass objects, nor with other types of window glass. Window discs can be melted and worked into fiberglass, to be incorporated into asphalt or even in yellow and white reflective street colors. Glass shavings then combine successfully with concrete to work on floors and granite surfaces.
Other recyclable materials
Zinc, aluminum, packaging, fabrics. These additional materials may also have reuse and recycling options. Of course, substances such as asbestos, latex paint, chemical solvents, adhesives and dyes on lead based, which have been carefully treated, also reduce the effects on the environment. With the growing concern to make the built environment more sustainable, the thought of the entire life cycle becomes one of material importance.
Recycling does not only reduce the likelihood of garbage dumps, but also reduces the pressure on landfills. Besides, it can lead to lower costs for the environment and consumers. By doing so, we can lower the need for new, natural resources that reduce production and transportation costs and eliminate the need to dispose of waste on landfills.
