The Uptick of Natural and Recycled Construction Materials

Investing in environmentally friendly construction results in a structure with lower carbon dioxide emissions, improved energy efficiency, and enhanced public perception of the organization as being environmentally conscious.

Time for a candid admission: despite our best efforts, we could not limit the number of material features. Simply put, there were too many excellent materials, and it would be unfair not to mention them all.

So be patient with us, and you’ll discover some surprises. Here are 15 of the most remarkable eco-friendly construction materials that are redefining the construction sector.

1. Straw Bale

Old things have a fresh lease on life! In the Great Plains, the pioneers built their houses from straw bales. This method has now been modernized for the twenty-first century.

Straw can be harvested using waste products from the agriculture sector. It serves as a lumber alternative while also capturing carbon. Remember that they won’t be as thin as a typical stick-frame house. The R-Value of these substantial, well-insulated walls is exceptionally high. Contrary to popular belief, straw bale houses can complement your preferred aesthetic and are fire-resistant.

These residences’ remarkable comfort level will impress visitors. The structures remain warmer in the winter and colder in the summer.

2. Bamboo

One of the most eco-friendly building materials, bamboo has an extraordinarily high generation rate. After harvest, it spreads and grows further without needing to be replanted. Except for Antarctica and Europe, bamboo grows practically everywhere and is a perennial grass, not wood.

Furthermore, it is stronger than concrete and brick, has a significant weight-to-strength proportion, and lasts a very long time. The ideal material for flooring and cabinets is bamboo.

However, it needs treatment to fend off rot and insects. Otherwise, the starch it contains will attract rot and pests and cause it to fracture or expand as it absorbs water.

3. Hempcrete

This eco-friendly substance resembles concrete and is formed from the inner woody fibers of hemp plants. The fibers are combined and bound with lime to create light, sturdy shape blocks that resemble concrete blocks.

It is lightweight and significantly reduces the energy required to carry blocks. Hempcrete is strong and has exceptional acoustic, thermal, and fire resistance properties.

It is also one of the fastest growing sustainable properties and absorbs more carbon dioxide than it emits due to its negative carbon dioxide content reading. As a resource, hemp itself is abundant and expanding quickly.

4. Rammed Earth

One of the earliest long-lasting methods of building structures is earth construction. Consider the Great Wall of China! These days, it is used to build striking, durable walls that mimic sedimentary rocks in opulent mansions.

By allowing the sun to warm them throughout the day and then gradually releasing the warmth during the cool evenings, rammed earth floors or walls can be utilized as thermal storage.

This low-carbon method employs forms in which layers of soil and binder are deposited before applying pressure to produce a tough and long-lasting surface.

These blocks, which any mason may erect, are made from low- or even no-cement waste materials that come from quarries.

5. Reclaimed Wood

One of the most well-known building materials in use today is wood. However, most of the wood may be destroyed while processing raw timber into wood planks and boards.

This waste material can also be employed to create engineered wood walls, panels, doors, and other structural components. In contrast to solid hardwood, engineered wood has multiple layers. Typically, the center layers are constructed of softwoods, wood fibers, or other types of scrap wood.

6. Concrete Molds with Insulation

In insulated concrete forms, there is a void between two insulation layers. After inserting the reinforcement, concrete is splashed into the area, which has a structure for supporting the bars.

They are less dense, easy to handle, fire-resistant, and have effective acoustic and thermal insulation properties.

7. Cob

Ever wonder what those intriguing, organic-looking houses are constructed of? They are made of a substance called cob, a combination of subsoil, water, brittle organic matter, and occasionally lime.

The oldest known mud building dates back more than 10,000 years, in case you didn’t know. Carbon emissions and global warming on top of the housing crisis definitely got us thinking about alternatives, and one of the materials making a modest comeback is cob.

In addition to being eco-friendly, cob is an organic substance that is simple to work with and, thanks to its texture, allows you to make any design you can think of. It is extremely energy-efficient and produces natural insulation. Due to this, cob homes don’t require much heating.

8. Bark Siding

By using tree bark as a construction material, sustainable forestry methods are evolving to new heights. Bark siding and bark shingles may not be familiar to you, but they are actually long-lasting, beautiful, affordable, and sustainable siding and shingling options.

Bark for construction projects originates from already-cut trees. You see, in the past, the bark was burned, thrown away as trash, or in some cases, used to make mulch. It is saved from this destiny and used as a highly eco-friendly substitute for conventional shingling and siding building materials.

Bark siding has a lifespan of up to 100 years without any sealing, painting, or routine maintenance. There is no chemical discharge because there is no paint or stain.

The bark is sterilized against fungus and bugs after being extracted from the already-felled trees; this sterilization procedure uses no pesticides or other dangerous chemicals. Additionally, kiln-dried bark won’t ever shrink or distort when installed.

9. Precast Concrete

The precast concrete slabs are created at a manufacturer’s facility and delivered to construction sites in whole portions. Some, like concrete blocks, are composed exclusively of concrete but contain substantial empty air spaces.

Precast concrete slabs can withstand a variety of weather conditions, making them ideal for walls and high-rise facades. Some slabs can also be used for floors and flat roofs.

Concrete is a cost-effective building material and an excellent technique for managing heat inside a structure. Precast concrete slabs are more environmentally friendly than many typical concrete choices since they require less energy to develop and build.

They can also be adequately cured in a controlled setting by precasting instead of being exposed to various unfavorable weather conditions while drying at a worksite. Due to this, concrete slabs prevent eventual demolitions by minimizing fissures and structural issues with the concrete.

10. Recycled Steel

Materials that retain their properties after being recycled include recycled steel. Did you know that the most recycled material worldwide is steel? Every year, steel recycling surpasses that of plastic, paper, aluminum, and glass.

When recycled steel is used in construction, you can be sure the final product will be sturdy and long-lasting. It also reduces energy expenditures significantly.

11. Polyurethane Foam

Buildings have historically used rigid foam as insulation. It was initially employed after a renowned surfboard material producer received a fine from the United States Environmental Protection Agency (EPA) and lost business as a result of using a harmful ingredient. The business for surfboards was revitalized by the use of plant-based polyurethane foam, which was produced from bamboo, kelp, and hemp.

It is now used to produce furniture and turbine blades, among other things. The substance can be utilized for insulation because it is rigid and largely immobile. It also provides a defense against bugs and mold.

Additionally, it can be the ideal sound insulation material and is heat-resistant as well as pest and mold-resistant.

12. Cork

The next time you open up that delicious bottle of wine, remember there is an alternative for cork than the dumpster.

The cork oak tree, one of the most renewable and environmentally benign resources, is used to make cork. Building cork ceiling tiles, acoustic walls, and flooring are just a few applications of this beautiful green buoyant material.

Cork is a strong, liquid- and moisture-resistant substance. Vibration can be absorbed by it because of its structure. Harvesting cork can aid in the effort to combat global warming.

13. Recycled Plastic

While the plastic bags we use every day take 10–20 years to break down, plastic water bottles take 450 years, and plastic products take thousands of years to break down in landfills. It’s time to begin cleaning up our planet and reusing all the plastic waste we have left to float freely in our parks, beaches, and houses.

Companies that generate construction materials from recycled plastic using a carbon-neutral, non-toxic processing technique produce substantially lesser greenhouse gas emissions than concrete blocks.

Recycled plastic is a robust and resilient material that is excellent at preserving sound. In the long run, reducing waste by creating this “green circle” and utilizing what we currently have will help.

14. Sheep’s Wool

An excellent substitute for chemical-laden insulation material is wool from sheep. It can insulate houses like regular insulation and uses less energy during production.

It can improve the building’s energy efficiency and soundproofing capabilities. Unlike other natural insulating materials like cotton and straw bales, it won’t break down soon. It is more widespread, simple to harvest, and develops quickly.

15. Ferrock

The iron-rich ferrous rock is created from recyclable resources, including glass- and steel-ground silica and scrap steel dust. It is typically used as a substitute for cement in building homes. The ability of ferrock to absorb, bind, and generally reduce pollution is excellent.

It is a remarkably tough and resilient material that is used for marine constructions, such as architectural features exposed to seawater. Ferrock has five times the strength of Portland cement!

Furthermore, it weighs between 10% and 25% less than a brick-built building. The actual ferrock development process is quite sustainable.
