5 Types of Wood That Improve Sustainability

Wood is a preferred choice for many when it comes to consumer products or building material. For starter, it is a natural resource which is renewable, has a low carbon footprint and recyclable. Moreover, there is an element of aestheticism and it can be used for artwork too.

Consumers and manufacturers can play their part in stopping climate change by using wood rather than other material. Natural wood products play a critical role in reversing climate change. As young trees grow, they remove carbon (a greenhouse gas emissions) from the air and store it while releasing oxygen. When the mature trees are harvested, the carbon remains stored in this physical entity, and new trees are grown for the continuation of this cycle. We will be sharing 5 types of woods which are easily available and sustainable.

Red cedar (Juniperus virginiana)

Red cedar (Juniperus virginiana) is a species of juniper native to the North America and Mexico. It’s a dense and slow-growing coniferous evergreen tree that produce a fragrant smell. In some parts of US, eastern juniper is commonly used as a Christmas tree. Red Cedar has a high level of tannin that make them insect and rot resistance. They are resistant to weather and temperature condition, hence suitable for making outdoor products. Red Cedar is considerably more expensive than other type of wood. They do not need to be stained and fades to a weathered grey over the years.

Real Cedar is a sustainably managed resource and is a major building material. For every tree harvested there are at least three replanted. The replanting effort has been so rapid that the total forest land base in North American has grown 20% since 1970.

Pará rubber tree (Hevea brasiliensis)

Pará rubber tree (Hevea brasiliensis) produce rubberwood, a light color tropical hardwood. Rubber Tree is well known for producing the milky white sap, known as latex. This latex is used for the production of all rubber-based products around the world. Products such as tires, rubber bands, medical glove, mattresses etc.

Rubber plantation trees are harvested for wood when they are around 25 years old, this is where the latex production become low. The trees are then felled, and young trees are planted. The wood is then treated to make them suitable for furniture making. A key advantage of rubberwood is their relatively low cost and ease of working via hand and machine.

Rubberwood is not suitable for outdoor use due to fungus and insect attacks. Excessive moisture will also cause the wood to warp and rot. On average the rubberwood can give you around 15 to 25 years of furniture use. An example of rubberwood product – Step stool.

Pine tree (Pinus)

Pine tree (Pinus) is a softwood tree and they grow around the world. They are fast growing tree species hence you can find commercial pine grown in plantation. The pine plantation is normally harvested after 25 years, although some can grow up to 50 years old due to their increasing commercial value.

Pine wood is lightweight, resistance to shock and easy to work with, hence popular for furniture and carpentry work. As they are not rot or insect resistant, the pine needs to be treated for outdoor purpose. As pine tree require less time to grow, growers are able to sell the wood at a lower price. Pine trees grow well on plantations with little impact on natural habitats, whereas oak used in furniture typically comes from old growth forests. Some examples of pine wood product – Birdhouse, Foot Stool, Tree swing. 

Chinese Fir (Cunninghamia lanceolata)

Chinese Fir (Cunninghamia lanceolata) is a native to China, Vietnam and Laos. They are a fast-growing tree species and resistant to insects and rot. The light color wood is a softwood, straight-grained and fragrant.

They are commonly used for reforestation program and agroforestry systems in China, as it is usually intercropped with a range of crops species. The interplanting is important for increasing the income of farmers and to avoid the land degradation that comes from continuous cropping of the Chinese Fir. You can frequently find them planted in areas where there are temples or monastery too.

Chinese Fir is strong, durable and easy to work with. This lightweight wood is used for housebuilding, furniture, flooring and coffins. Produce a similar smell to Coast Redwood.

Bamboo (Gramineae: Bambusoideae)
