"Pretty much all steel will get recycled when a structure is dismantled," adds Moe. Steel, in fact, is the most recyclable commodity on the planet, with around 98 percent of structural steel avoiding landfills. Although sorting out multi-material architectural pieces might be challenging, it can lead to safer reuse. "Most buildings collapse because they're poorly constructed. If you remove the risk of collapse by using proper demolition techniques, then people aren't going to be afraid to go into buildings."
Demolition also generates new resources which could be used instead. For example, demolition debris can be reused for roads or playgrounds, while the metal inside appliances and cars can be recycled.
Finally, demolition can be an opportunity to improve living conditions in communities where many people make a meager income from small farms or micro businesses. By reducing the need for expensive construction projects, demolition can help families lift themselves out of poverty. This is what has happened in India, for example, where poor farmers have been able to afford modern farming methods like hydroponics because of the revenue they generate from selling their buildings and other abandoned property.
For all these reasons, demolition is very important for the environment, but also for human health and safety. The process must be done properly or else dangerous substances released during destruction can pollute soil and water sources.
In conclusion, demolition is necessary for the preservation of our environment.
Repairing and repurposing old structures conserves energy and materials while reducing waste. New materials do not need to be developed, nor do old destroyed materials need to be discarded. Furthermore, energy for reconstruction is saved. In addition, demolishing buildings releases chemicals and contaminants into the environment. Demolition also causes noise pollution as buildings are torn down.
Who would have thought that saving old buildings would be so important to our environment? Yet it has been proven time and again that preserving the past saves the future.
Old buildings can be restored or replaced and they often offer better environmental options than new buildings. The benefits of replacing a building rather than destroying it include saving energy, reducing demolition debris, conserving water, and protecting local communities by providing employment.
Demolition is simply the safe and thorough demolition of old structures and buildings in order to repurpose the property. It can refer to either totally destroying a structure or dismantling a load-bearing portion of a structure in order to reuse or recycle components. The term "demolition" also refers to the act of destroying something: "that house will be demolished next year."
Simple demolition is simple removal of usable materials from an older building or structure. This includes removing doors, windows, and other items that may have value when recycled or reused. Some examples of useful materials include wood, drywall, insulation, plumbing, wiring, and flooring. Any other material found inside the building is considered waste and should be removed before demolition begins.
The goal of simple demolition is to make the building or structure easier to handle during more complex demolitions or rebuilds. For example, if there are large pieces of concrete in the way during construction, they can be cut up and used as fill dirt outside the building or destroyed by burning them.
Large buildings require multiple methods to complete a demolition. Simple demolitions can be done with one tool at a time but usually involve some type of machinery. Smaller items that can be handled individually are often thrown into a dumpster for disposal. Waste materials such as glass, metal, and paper should be collected separately in order to prevent fines for violations of local ordinances.
A structure is very old: It is possible that a building's foundation is weak or not solid owing to its age. Older structures may contain hazardous elements, such as asbestos, that mandate their destruction or partial demolition. In some cases, buildings are demolished to make way for improvements or new developments.
The reasons for demolishing a building vary depending on its age, location, and other factors. Buildings more than 100 years old may be considered historic landmarks and destroyed if they cannot be preserved through some alternative means. Old buildings can also be demolished to make room for businesses or residences. Structures built before 1990 in most states are required by law to have electricity inside them in order to be considered habitable. If they are not connected to the power grid, they must be demolished in order to prevent the danger of people being trapped inside.
Buildings located in poor condition that pose a threat to those working on or visiting nearby properties may be demolished by their owners as part of an overall plan. For example, a property owner may seek permission from local authorities to destroy a structurally deficient garage or shed because it is an eyesore or potential hazard. Buildings used for illegal purposes may be demolished by police or code enforcement officers after receiving complaints from neighbors.
Demolition is usually the preferred option when dealing with dangerous buildings.
