Building a Sustainable Future: Harnessing Recycled Materials for New Construction

by Mary Klett, ASA Communication Team

As the world faces pressing environmental challenges, the construction industry is embracing a transformative shift towards sustainable practices. There’s a lot of pressure on engineering and construction companies to lower the carbon footprint of new and retrofit construction projects. One notable approach gaining traction is the use of recycled materials. By repurposing waste into valuable resources, this innovative method not only reduces environmental impact but also offers significant cost savings. In this article, we will delve into the benefits of utilizing recycled materials, citing studies on cost savings and environmental impact, exploring innovative designs, and showcasing inspiring examples of new construction in the United States.

Cost Savings and Environmental Impact:

1. Cost savings: Incorporating recycled materials into construction projects can lead to substantial economic advantages. Studies have shown that using recycled materials can result in cost savings ranging from 10% to 20% compared to traditional construction methods. Recycled materials, such as reclaimed wood, salvaged metal, and crushed concrete, can be sourced at lower prices, reducing material acquisition expenses.

2. Environmental impact: The environmental benefits of utilizing recycled materials in construction are undeniable. By diverting waste from landfills, this practice reduces the need for raw materials extraction, conserving natural resources and energy. Additionally, recycled materials often require less energy during the manufacturing process, resulting in lower greenhouse gas emissions. A study conducted by the U.S. Environmental Protection Agency (EPA) estimated that construction and demolition waste accounts for nearly 40% of the total waste stream. Implementing recycled materials can significantly decrease this impact and promote a circular economy.

Innovative Designs:

1. Shipping container architecture: One of the most remarkable examples of using recycled materials is the growing popularity of repurposing shipping containers as building units. These durable and stackable containers offer an affordable and sustainable alternative to traditional construction.

From offices and schools to residential spaces, architects and designers have embraced the versatility of shipping container structures, which can be modified to meet various functional and aesthetic requirements.

2. Recycled plastic building blocks: Plastic waste poses a significant environmental threat, but innovative solutions are emerging. Companies are now manufacturing building blocks made entirely from recycled plastic, offering a durable and lightweight alternative to traditional construction materials. These blocks are not only sturdy but also easy to assemble, providing cost-effective and sustainable options for affordable housing and disaster relief efforts.

Examples of New Construction in the United States:

1. The Bullitt Center, Seattle: Located in Seattle, Washington, the Bullitt Center is a pioneering example of sustainable construction. Built to meet the Living Building Challenge, the six-story structure boasts a range of recycled materials, including salvaged wood, recycled steel, and reclaimed bricks. It features rainwater harvesting, solar panels, and composting toilets, making it one of the greenest buildings in the world.

2 .While many examples exist in Europe, check out Austin’s Central Library in Texas as an example of sustainable construction. Natural light illuminates much of the atrium – this reduces the structure’s dependence on electric lighting. A rooftop rainwater harvesting system supplies the restrooms and also waters the surrounding gardens and landscaping. Architects also designed the library using ecofriendly materials, with a high proportion of recycled or locally produced elements. In the end, it operates 30 percent more efficiently than the energy code requires.

Decarbonizing what is today a very carbon-intensive industry will require the combined ingenuity and efforts of architects, designers, builders, subcontractors, suppliers, technology service providers, and operating owners. The adoption of recycled materials in new construction presents a sustainable solution that addresses both environmental concerns and economic benefits. By reducing waste and minimizing resource extraction, construction projects can significantly decrease their carbon footprint. The cost savings associated with using recycled materials further incentivize this eco-friendly approach, making sustainable construction a viable option for a wide range of projects. As we move towards a greener future, embracing innovative designs and learning from inspiring examples like the Bullitt Center and Austin’s Central Library will undoubtedly pave the way for a more sustainable built environment. By utilizing recycled materials, we can build a brighter future where construction is in harmony with our sustainable goals.
