The Sustainable Revolution in Construction
As the world turns its attention to sustainability, the construction industry must follow suit. But what exactly is sustainable construction, and how can we transition to more eco-friendly building practices? Sustainable construction is the practice of creating a healthy environment based on ecological principles. According to Professor Charles J. Kibert, it focuses on six key principles: conserve, reuse, recycle, renew, protect nature, and create non-toxic, high-quality environments.
The goal is to reduce the construction industry’s impact on the environment by embracing sustainable development practices, employing energy efficiency, and taking advantage of green technology. While many sectors are making strides towards sustainability, the construction industry is uniquely positioned to play a significant role. After all, the industry consumes vast amounts of materials and energy, making it a prime target for sustainable transformation.
The Rise of Sustainable Building Materials
One of the best ways to practice sustainability in construction is through the materials we use. A new generation of stronger, lighter, and revolutionary building materials are emerging to help solve many of the industry’s problems while promoting a cleaner, more sustainable future.
Let’s take a look at some of the most exciting sustainable building materials that are making waves in the construction world:
Bamboo
Bamboo is one of the most sustainable construction materials, thanks to its renewable and versatile characteristics. Despite being a type of grass, bamboo has a strength similar to wood while still being flexible. Construction projects can utilize bamboo in various applications, such as supporting concrete, scaffolding, roofing, and building other structures.
Recycled Plastic
In 2021, the world generated a staggering 139 million tons of single-use plastic, with the majority ending up in landfills or polluting waterways. Fortunately, advancements in construction and technology have enabled us to recycle plastic and create building materials like plastic sheets, bricks, and lumber.
Mass Timber
Also known as laminated timber, mass timber is a prefabricated timber product that has higher strength and water resistance than traditional timber. Its strength and water resistance make it a potential replacement for steel and concrete, both of which have a much higher carbon footprint during production.
Natural Stone
Stone is a naturally occurring material that can be used as both a building material and home furnishings, such as tiles and countertops. Stone is durable, low-maintenance, and versatile, producing little to no waste when used in construction projects. Since it’s a naturally occurring material, stone often doesn’t require energy-intensive factory production, reducing CO2 emissions.
Cob
Cob is a mud mixture made from natural materials like soil, straw, sand, and lime. Cob is commonly used in the construction of residential buildings or as a replacement for concrete structures. The making of cob is inexpensive and produces less CO2 than producing concrete, although it takes longer to build with and is more susceptible to mold in high-humidity environments.
Cork
Cork is a renewable and recyclable resource that is commonly used in European construction to insulate homes and other buildings. Cork is harvested by hand from the bark of cork oak trees, and this process does not require killing the tree, making it an eco-friendly replacement for traditional insulation.
Adobe
The use of adobe brick dates back centuries and is popular in the Middle East and the Americas. Adobe is a mixture of clay and straw that is used to make bricks for the construction of homes and other structures. The main appeal of adobe is that it uses naturally occurring materials from the earth and takes less energy to produce.
Reclaimed Wood
Reclaimed wood technology can now deconstruct lumber from older structures while preserving its integrity. Contractors and carpenters can use this reclaimed wood in new building projects or in home furnishing and decor, reducing waste and the need for new timber.
Precast Concrete
While concrete tends to be a factor in CO2 emissions at construction sites, it is still a much-needed material. Precast concrete, which is factory-made in exact measurements and then shipped to the construction site, can help mitigate the environmental impact of concrete production.
Mycelium
Mycelium, the thin fibers from fungi that run underneath the ground, can be harvested and dried to become an extremely durable, water-resistant, and fire-resistant building material. Dried mycelium can be combined with other materials like sawdust and demolition waste to create bricks for building structures, revolutionizing the construction industry.
Sheep’s Wool
Sheep’s wool is a renewable and natural resource that can be harvested and used without harming the animal. While typically used in clothing and textiles, sheep’s wool is also useful for insulating buildings. Unlike human-made insulation, sheep’s wool is natural, non-toxic, and mold-resistant.
Pollution-Absorbing Bricks
With growing environmental concerns, air pollution is one of the main problems that has proved difficult to solve. Pollution-absorbing bricks, which have porous blocks that allow air to pass through and filter out pollutant particles, offer a sustainable air-filtering alternative to traditional earth bricks.
3D-Printed Concrete
We know that concrete is a building material that’s not going anywhere anytime soon. While there are viable alternatives to concrete, there are also ways to make the production of concrete more sustainable, such as the use of 3D printing. 3D-printed concrete allows contractors to digitally design any shape and use concrete to print it, reducing waste and energy consumption.
Cordwood
Cordwood is a building method that uses stacked short logs, similar in shape to firewood, to build a wall. Cob or mortar is used between the wooden logs to secure everything together. The cordwood technique is typically seen in homes and provides a rustic cottage look while offering natural insulation and the ability to use local materials to save energy and money on transportation.
Recycled Rubber Tires
Until recently, rubber tires weren’t recycled and were left cluttering landfills. Thankfully, experts have found that the rubber found in tires provides durability, flexibility, and insulation, all of which are important factors in building materials. Some sustainability-focused homes, known as Earthship homes, use recycled tires filled with sandbags as insulation, while others are working on ways to make rubber masonry blocks with recycled tires for new structures.
Newspaper Wood
Although paper is one of the easiest materials to recycle, paper waste is a growing concern. With new innovations and advances in technology, companies like Newspaper Wood are seeking to turn paper back into wood, which could have promising results in furniture and home decor, though it’s not yet usable in construction projects.
Eco-Friendly Rigid Foam
Rigid foam has been around for a few decades as an effective insulator for homes and commercial buildings. However, a key compound in the original version of rigid foam was found to be harmful to the environment. That’s where rigid foam’s newer eco-friendly counterpart, made with a mixture of bamboo, hemp, and kelp, comes in handy. This improved rigid foam is great for wall insulation, furniture, and even surfboards.
Straw Bale Insulation
The use of straw in construction dates back centuries before our current day, but it still proves to be one of the most sustainable building materials readily available today. Like many of the other materials mentioned, straw is a renewable resource that works well as insulation, and as long as it is properly protected from moisture, straw bale insulation can last for years.
Recycled Glass
Glass is one of the hardest materials to recycle, leaving it discarded in landfills and high-pollution areas. However, recent studies have found that construction projects can use waste glass to imitate natural aggregates like sand, gravel, and crushed stone. Cement makers can also use recycled glass in their mixture, though using recycled glass is not yet a common practice in construction.
Recycled Steel
As previously mentioned, producing steel can be harmful to the environment, yet it continues to be necessary for building frameworks and supporting entire structures. One of the best qualities of steel is that it has an unlimited life cycle, which means it can be recycled repeatedly without losing its quality or durability. Seeking out recycled steel for new construction projects saves energy while effectively reducing a project’s carbon footprint.
The Benefits of Sustainable Construction
Sustainable construction goes beyond the materials contractors use in their projects. Certain construction practices and methods are proven to be more earth-friendly and enhance sustainable efforts. These include, but are not limited to, value engineering, modular design, and on-site renewable energy generation.
