Top 10 Sustainable Building Materials

Sustainable Materials

This list of the top ten sustainable building materials includes materials drawn from nature that are renewable, are recyclable, or that use scrap or waste from other processes to make new materials. Some are materials you’ve heard of, and probably used before, while others may be new to you. Using sustainable building materials can help reduce the impact of construction on the environment and help conserve resources for future generations.

What is sustainable construction?

Sustainable construction refers to the practice of creating structures and using processes that are environmentally responsible and resource-efficient throughout a building’s life cycle. This includes its design, construction, operation, maintenance, renovation, and eventual demolition. The main goals of sustainable construction are:

  1. Minimizing Environmental Impact: Sustainable construction aims to reduce the environmental footprint of buildings. This involves using energy more efficiently, reducing waste, and minimizing the use of non-renewable resources.
  2. Efficient Use of Resources: This includes the efficient use of materials, water, and energy. The use of renewable and recyclable materials is encouraged, as is the efficient design of buildings to reduce energy and water consumption.
  3. Enhancing Quality of Life: Sustainable buildings are designed to be healthier and more comfortable for occupants. This includes improving air quality, natural lighting, and thermal conditions.
  4. Economic Efficiency: While sustainable construction methods may sometimes have higher upfront costs, they often lead to savings in the long term through reduced energy and water bills, and lower maintenance costs.
  5. Social Responsibility: Sustainable construction also involves considering the impact of the building on the local community and its workers, ensuring fair labor practices and contributing positively to the local environment and society.
  6. Innovation in Design and Materials: It often involves innovative design and the use of new materials that are more sustainable, durable, and recyclable.
  7. Compliance with Regulations: Sustainable construction practices often align with or exceed current environmental and building regulations.

Sustainable construction is not just about reducing the environmental impact of buildings but also about creating healthier, more efficient, and economically viable spaces. It represents a holistic approach to building that considers the long-term implications of construction on the environment and society. Here’s a summary of these materials and their relevance to sustainable construction practices:

  1. Bamboo

Bamboo is a versatile, strong substitute for wood products in a variety of materials. From flooring to textiles, this fast-growing grass has all the beauty and strength of wood, and it grows on every continent except Europe and Antarctica. In Asia, bamboo is often used for structural components for buildings, as it has a high strength-to-weight ratio and greater compressive strength than concrete and brick. Because it grows so rapidly (up to three feet within 24 hours), it doesn’t take long to replenish supply once its been harvested. 

  1. Cork

Cork is harvested from the outside bark of the cork oak tree, found only in the Mediterranean. After it is removed, the tree replenishes the bark, allowing more to be harvested. It makes a wonderful, soft flooring product, is naturally antibacterial and antimicrobial, and is resilient and resistant to wear. It’s perfect for kitchens and bathrooms.

  1. Steel

You might not think of steel as being sustainable, but the majority of steel used in the construction industry is recycled and is recyclable once it’s reached the end of its useful life. Because it can be reused many times, it cuts down on the raw resources needed to create each product. So, instead of having to cut down new trees to create lumber, existing steel can be melted and recast without harvesting new metal.

  1. Mass timber

Mass timber is created by bonding softwood to form large prefabricated wood components which are used as structural members in the construction of a building. The process allows buildings to be constructed faster and with less waste than traditional building materials. It’s been shown that mass timber reduces global warming potential by an average of 26.5% over concrete and steel.

  1. Mycelium

Mycelium is a one-celled organism that is found in the root structure of fungi and mushrooms. It is being used to create bricks, blocks, insulation, and concrete. The organisms are encouraged to grow around a composite of other materials, like straw or sawdust, in a form or mold. Then it’s air dried to create a brick or other uniquely shaped building component. It’s durable, can withstand extreme temperatures, and is compostable.

  1. Linoleum

This versatile flooring product has actually been around since the 1800s, and it’s made up of all natural ingredients. Mix flax, pine rosin, wood flour, cork dust, calcium carbonate, and jute and you have it. It comes in a variety of patterns and colors to match any décor and requires little maintenance.

  1. Wool carpet

These days the most popular material for carpeting is nylon or other synthetic fibers, man-made materials. Wool carpet is a natural, durable alternative to these fibers. It is naturally moisture-resistant and provides additional insulation to keep your feet warm.

  1. Ferrock

Haven’t heard of this one? It’s no wonder, as it’s only been developed in the last few years. It combines recycled steel dust and/or ferrous rock left over from industrial processing and creates a concrete-like material that is stronger than concrete. It is a carbon neutral process and is less CO2 intensive than creating concrete.

  1. Plant-based foam

Plant-based polyurethane foam, originally designed for use in making surfboards, provides great thermal and sound insulation in buildings, and can be used for manufacturing furniture and turbine blades. The material is made from bamboo, kelp, and hemp.

  1. Sustainably harvested lumber

Yes, lumber can be a sustainable building material when the forest is managed responsibly, with longevity in mind. Practices such as selective logging, replanting, controlled burns, and pruning help forests produce timber products for generations to come, ensuring that these materials are available, while preserving natural habitats and microclimates. Look for branded lumber that has been harvested according to these practices.
