Sustainability is important. With ever-increasing greenhouse gas emissions resulting in warmer global climate temperatures and sea level rise, it is crucial to act quickly to mitigate the damage caused by climate change. While individual acts of sustainability help, industries must act too, especially construction. Here are some of the best building materials to consider for green building.


Bamboo is today one of the best materials for sustainable construction. It grows like a weed, so there is a constant supply of bamboo available. Best of all, bamboo grows on almost every continent except Europe and Antarctica in just a few days. This means that there is an ever increasing supply in a short period of growth. It is strong, resistant and durable. Builders will see the force parallel to concrete and bamboo brick. However, due to the natural makeup of bamboo, insect and rot treatment is necessary to prevent damage.

Straw Bale

Straw bales are another popular alternative to green building. Straw is an excellent structural material commonly used as insulation and for soundproofing. It is also used as a filling material for wooden beams. Since straw bales do not allow oxygen to pass through, it is a naturally fire resistant material that can withstand older or wooden buildings.

Recycled plastic

There are many reasons why recycled plastic opens up new horizons in construction. It is today one of the most ecological materials. Considering the amount of plastic dumped in oceans and ecosystems around the world, recycled plastic is a great way to reuse and reuse discarded waste into usable materials. One solution is to use the high density polyethylene found in recycled jugs, bottles and containers. Using HDPE plastics reduce the environmental impact of manufacturing, further reducing carbon emissions and fossil fuel consumption. Not to mention the high strength polymers which make it a durable and resistant alternative to wood, concrete and brick.


Wool isn’t just for expensive clothes. As one of the best building materials for green building today, it is an excellent natural insulator for homes and requires less energy to manufacture than contemporary insulation. Like straw, it can be used as a soundproofing material. Unlike other conventional insulating materials like cotton, wool grows back relatively quickly. Sheep shearers can harvest it without harming the animals. It also requires less floor space than cotton, which further decreases deforestation and destruction of natural habitats.
