Recycling Remains of Demolished Buildings: Innovative Practices and Solutions
As the construction industry continues to evolve, so too does the push for sustainable practices. One crucial aspect of this movement is the recycling of materials from demolished buildings. The process of recycling materials from demolition sites not only reduces waste but also conserves resources and minimizes environmental impact. In this article, we explore innovative practices and solutions for effectively recycling the remains of demolished buildings.
Onsite Rubble Recycling
Modern construction methods have introduced significant advancements in the recycling of demolition debris. These days, the rubble is often reduced to gravel onsite before it is even trucked away. This process helps in utilizing the material on-site for road beds and driveway underlay, reducing transportation costs and the environmental footprint. As a result, the rubble is transformed into a valuable resource rather than becoming waste.
Utilizing Demolished Structures for Other Purposes
In some cases, buildings and structures that are being demolished are used for other purposes. This approach is not only cost-effective but also environmentally beneficial. For example, in instances where asbestos is present, the material must be handled with extreme caution. Asbestos was commonly sprayed on steel girders and used in roofing and floor tiles for many years, making it challenging to recycle. Similarly, other materials like drywall and wood that have been crushed are difficult to manage.
One innovative solution for managing concrete structures from industrial properties, such as former refineries, is to bring in a crushing machine. This machine can transform old concrete into material suitable for road beds, ensuring that no material goes to waste. Roofing tiles can usually be recycled into paving materials, which further extends their useful life.
Reusing and Repurposing Materials
Several options can be considered when dealing with the recyclable materials from demolished buildings. Copper and other metals have value as scrap and can be sold or taken free of charge to be sold on the market. Doors, windows, flooring, cabinets, and plumbing fixtures can often be reused if they are in decent condition. Non-profit organizations like Habitat for Humanity and their 'Restores' are great resources, as they may pick up or accept donations and resell or repurpose the materials to raise funds and reduce waste.
Lumber, a versatile material, can be used in various ways. Friends might be interested in joining you for a nail-pull session, or you can gift smaller pieces as firewood. For larger scrap, it might be useful to find a local developer who could accept the clean concrete waste as landfill. Drywall and shingles, however, are typically considered waste and will need to be paid to landfill.
Efforts to recycle a fair percentage of building rubble require some input and creativity. Bricks, for instance, can be resold for reuse, and doors and windows can be sold or dismantled for material reuse. Steel is another valuable material that can be recycled for melting. Other materials can be used as fill material, further reducing the environmental impact.
By adopting these practices and solutions, the construction industry can significantly reduce its environmental footprint while promoting sustainability. The key is to think creatively and find innovative ways to repurpose materials, reducing the amount of waste sent to landfills and maximizing the value of each demolition project.
