Sustainable materials for buildings

Learn something new every day More Info Sustainable construction materials are building materials made from recycled products and resources that can be replenished in a relatively short amount of time. There are many types of sustainable construction materials, often referred to as green building products.

Lumber, stone, metal and paper are materials that can be recycled and re-used as building products. Bamboocork, straw and even coconut are examples of construction products that can be renewed quickly. Reclaimed lumber is the most widely used recycled material used for green building.

Lumber is taken from old structures, treated and re-sized for use on other projects. Using reclaimed lumber preserves timber and saves energy because fewer resources are used to recycle the lumber than would be used to harvest, treat, plane and transport new lumber. Recycled lumber can be more expensive than first-use lumber because of the costs associated with reclaiming and treating it.

Reclaimed lumber can also contain chemicals from previous treatments, which might be harmful to the environment. Nearly any natural materials, including stone, metal and concrete, can be reclaimed and used as sustainable construction materials. The advantages and disadvantages of using them are similar to those related to using reclaimed lumber. One of the biggest concerns with using recycled natural products is the presence of volatile organic compounds VOCs.

What Is the Meaning of Sustainable Materials?

VOCs can be present in the reclaimed materials as a result of things such as paints, stains and other chemical treatments, especially those applied before stricter environmental standards were in place.

Easily renewable products such as bamboo and cork are becoming more common as sustainable construction materials. Bamboo is a fast-growing plant that is being used more frequently in sustainable building designs. It replenishes quickly because of its rapid growth cycle and is versatile in its application. Bamboo is used most frequently as flooring and to reinforce concrete. More and more homes and building are being constructed from bamboo.

Cork also is gaining popularity as a sustainable construction material. Harvesting cork requires the removal of the bark from the tree but does not require that the entire tree be cut down. Cork makes a flooring material that is becoming more common in residences around the world.Due to migration of article submission systems, please check the status of your submitted manuscript in the relevant system below:.

Awareness and use of sustainable materials are important to your small business: Besides being better for the earth, customers like them too. Sustainability, whether in materials, energy or practices, means a limited negative impact on natural resources and people; they avoid depleting or degrading the environment.

Because they create few stresses on the environment, society can safely rely on them well into the future. Over time, less-sustainable materials tend to be phased out as better ones are introduced.

Products go through a life cycle that begins with production and ends with disposal.

Raw materials are extracted from nature, made into useful goods, have a functional life and are eventually discarded. Sustainable practices look at each step in the cycle and seek to avoid negative environmental consequences. For example, carefully managed tree cutting for wood production allows the forest to grow new trees at a rate that can keep up with the need for wood materials.

Wood, bamboo and other plant-based materials are sustainable because they grow naturally. Aluminum, copper and other metals recycle indefinitely. Paper and related products are based on natural fibers, can be recycled and degrade rapidly once disposed of. Common sustainable building materials include cork, steel and recycled plastics.

In addition to using sustainable materials, some businesses offer recycling programs that take in discarded products for recycling rather than have them enter landfills.

This actively encourages customers to discard their products in a sustainable manner. The durability that makes certain materials attractive can be a liability at the end of their useful life. Many plastics, for example, consist of long-chain molecules that can take centuries to break down, leading to waste that lasts seemingly forever.

To address the problem, chemists have created biodegradable synthetic materials that have a known useful life, after which they disintegrate completely by sunlight and naturally occurring microorganisms.

Biodegradable materials such as this have short-term uses such as food packaging. Recycling is sustainable because it reduces both the need for virgin materials at the start of the life cycle and landfill space at the end.

Metals and glass can be melted and reused almost without limit. Most plastics degrade chemically somewhat, but some useful recycling is possible. Paper and cardboard can likewise be recycled a few times, though not forever. Plastics and many other materials come from oil and petrochemicals, a limited resource whose consumption has come with serious environmental consequences.

Most efforts at developing sustainable materials avoid the use of petroleum and other fossil fuel sources.Buildings are responsible for large amounts of CO2 during their construction and maintenance. Thankfully, more sustainable material options are available for developers, with innovation happening from the foundations right up to the roof.

Thankfully, numerous more sustainable alternatives exist, some of which add recycled materials such as crushed glass, wood chips or slag — a byproduct of steel manufacturing — to the mix.

As well as finding another use for waste products, concrete mixes are typically lighter than traditional concrete. For those looking for something bolder, concrete alternatives exist. Hempcrete has similar properties to concrete, but is made from from the woody inner fibres of hemp plants, bound together with lime. An even more natural alternative would be the ancient construction method of rammed earth. As the name suggest, this is literally compressed dirt, but modern innovations have introduced mechanical tamping and strong wooden frames.

Waste is reduced by casting concrete construction panels off-site, creating economic and environmental benefits through more efficient mass production.

It takes a lot of energy to produce building materials, even many that are marketed on their sustainability credentials. Reusing materials that have already been produced can therefore be a key part of sustainable construction. Along with the concrete hybrids mentioned above, recycled scrap steel is an ideal eco-building construction material.

Nature provides an answer in wool, which has been protecting animals from the elements for quite some time. There have been attempts to use the natural benefits of wool in other construction materials. Unlike traditional bricks, wool bricks dry hard without needing to be fired, reducing their energy requirements. Traditional roof tiles are either mined from the ground or set from concrete or clay, all of which are energy intensive methods.

Once installed, they exist with one primary function — to protect a building from the elements.

That element is likely to be rain or wind, but in some regions, rooftops have been designed to protect buildings from the impact of the sun. Seeing this as an opportunity, and harnessing technological developments, solar tiles were born.

Made from recycled newspapers and cardboard, paper-based insulation is a superior alternative to chemical foams. Being mechanically blown into cavity walls means it is excellent at surrounding pipes, wires and filling holes, reducing the chance of air flow. Both insect resistant and fire-retardant thanks to the inclusion of borax, boric acid, and calcium carbonate all completely natural materialspaper insulation also has the advantage of absorbing noise.

Bamboo has been used in construction in some parts of the world for centuries due to its light weight and high tensile strength. Unlike trees such as pine and oak, bamboo grows quickly, making it easier and less intensive to produce for construction.

Many building design considerations are based on local traditions where bamboo might not be the desired end finish, but it can also be used for unseen elements behind the walls and beneath flooring.

Being light and strong, bamboo is ideal for projects in areas that are hard to reach, often deployed in building projects in post-disaster regions. Triple-glazed windows can offer better thermal insulation than some walls, especially when combining three layers of glass with fully-insulated window frames. In most double-glazed windows, the gas argon is injected between each layer of glass to aid insulation, but in super-efficient windows, krypton — a better, but more expensive insulator — is used.

Low-emissivity coatings are also applied to the glass, which further prevent heat from escaping. Photo: Ricardo Gomez Angel. This is an updated version of a post originally published in November Your email address will not be published.

From homes and apartment buildings to bridges, viaducts, and sidewalks, this ubiquitous gray material's importance to modern urban life is undeniable. But you might have heard that it also has a dirty secret: the production of commercial concrete materials releases tons of the greenhouse gas carbon dioxide CO2 into the atmosphere each year, contributing to the calamity that is climate change. But it doesn't have to be that way.

We have collated 11 green building materials that offer alternatives to concrete, and a lower environmental impact. Rather than relying on new research and technology, straw bale building hearkens back to the days when homes were built from natural, locally-occurring materials.

As its name might indicate, grasscrete is a method of laying concrete flooring, walkways, sidewalks, and driveways in such a manner that there are open patterns allowing grass or other flora to grow.

In fact, walls that have a similar feel to concrete can actually be created with nothing more than dirt tamped down very tightly in wooden forms. Rammed earth is a technology that has been used by human civilization for thousands of years, and can last a very long time.

Modern rammed earth buildings can be made safer by use of rebar or bamboo, and mechanical tampers reduce the amount of labor required to create sturdy walls. HempCrete is just what it sounds like — a concrete like material created from the woody inner fibers of the hemp plant. The hemp fibers are bound with lime to create concrete-like shapes that are strong and light.

HempCrete blocks are super-lightweight, which can also dramatically reduce the energy used to transport the blocks, and hemp itself is a fast-growing, renewable resource. Bamboo might seem trendy, but it has actually been a locally-sourced building material in some regions of the world for millennia.

What makes bamboo such a promising building material for modern buildings is its combination of tensile strengthlight weight, and fast-growing renewable nature. Used for framing buildings and shelters, bamboo can replace expensive and heavy imported materials and provide an alternative to concrete and rebar construction, especially in difficult-to reach areas, post-disaster rebuilding, and low-income areas with access to natural locally-sourced bamboo.

Instead of mining, extracting, and milling new components, researchers are creating concrete that includes ground up recycled plastics and trash, which not only reduces greenhouse gas emissions, but reduces weight and provides a new use for landfill-clogging plastic waste. Plain old wood still retains many advantages over more industrial building materials like concrete or steel.

Not only do trees absorb CO2 as they grow, they require much less energy-intensive methods to process into construction products. Properly managed forests are also renewable and can ensure a biodiverse habitat. Mycelium can be encouraged to grow around a composite of other natural materials, like ground up straw, in molds or forms, then air-dried to create lightweight and strong bricks or other shapes.

Ferrock is a new material being researched that uses recycled materials including steel dust from the steel industry to create a concrete-like building material that is even stronger than concrete.

AshCrete is a concrete alternative that uses fly ash instead of traditional cement. Timbercrete is an interesting building material made of sawdust and concrete mixed together. Since it is lighter than concrete, it reduces transportation emissions, and the sawdust both reuses a waste product and replaces some of the energy-intensive components of traditional concrete.What if we could use mushrooms to warm our homes?

Or use shape-memory alloys to make our infrastructure more sustainable? Volvo Construction Equipment takes a look at some of the future technology with the potential to radically transform the way we build.

Wood has been a construction material for thousands of years and it could be making a big comeback. Cross-laminated timber could be the answer. Consisting of small pieces of softwood laminated together to become a larger structure, it is glued under tremendous pressure in opposing directions to give it superhuman strength — wood affected by drought or insects can still be included in these panels without compromising structure integrity.

This engineering process also allows panels to be made to measure, creating flat packed structures that can be constructed much faster than conventional material. With a lower embodied carbon footprint, its potential for off-site construction also makes it a sustainable product.

Some projects could even be completed six times faster than a standard building project. The material comes in batched rolls and can be speedily laid up to 10 times faster than conventional concrete. Both of these novel materials are already being used in the building of infrastructure around the world.

Anglia Water in the UK became the first water company to use Cemfree in and Concrete Canvas has been used to create storm drains and build emergency infrastructure following natural disasters. Some materials might seem out of this world, but this one is actually created with the help of aeronautic scientists.

By removing free radicals and other pollutants that come into contact with its photocatalytic surface, it has the benefit of reversing pollution and improving air quality at the same time as keeping surfaces clean. According to its creators, just 4 m2 of this material has the capacity to reduce the same amount of nitrogen oxide pollutants produced by a car over a whole year.

If we can adopt these kinds of resourceful solutions, we can reduce and maybe even reserve the effects of global pollution. Cross-laminated timber Wood has been a construction material for thousands of years and it could be making a big comeback. Memory Steel.

Pressure relief damper with counter weight

Memory steel is a clever material that can be used to reinforce new and existing concrete structures and could be a gamechanger for infrastructure. Consisting of shape memory alloys based on iron that contracts during heating, it permanently pre-stresses the concrete structure as it heats, which means it needs to be pre-stressed just once.

Other more conventional methods require the steel reinforcements in concrete structures to be pre-stressed under hydraulic tension to improve the strength and performance of the final concrete structure — requiring not only a lot of time but also a lot of equipment and space, all of which have an impact on productivity and sustainability. Because the strengthening of existing bridges, roads and highways often provides its own limitations on space, memory steel could revolutionize not just the way we build new infrastructure but also the way we renovate older structures.

We need to work to reduce this in the long-run, but in the meantime, there are some ingenious solutions to turn waste into material.

One such solution is a UK-based concept to create chipboard building material from potatoes. Inspired by the circular economy that we see in nature, effectively where resources and waste are used again in a long-lasting environmental loop, the concept allows for needless food waste to be regenerated as a sustainable building material.

Researchers from around the world have found ways to harness the incredible potential of mushrooms for use as building insulation. The insulation is made from the vegetative part of mushrooms, known as mycelium.

The process of mycelium bio fabrication works by letting the fungus from a mushroom feed on a substrate, such as sawdust. The fungus will then grow to the shape of the mold it is placed in and its growth is only halted when the fungus is dried. The final dried product can then be sanded and painted to suit its intended use. Because the material is naturally self-extinguishing and air purifying at the same time, it actually removes carbon from the atmosphere and becomes even stronger in the process.

This innovative material could be used in the construction of anything from airports to houses. Image 1: What are the sustainable building materials of the future?
