Chinese Scientists Pioneer Low-Carbon Building Materials Inspired by Worms

23 Oct 2023

In an exciting breakthrough in sustainable construction, a group of Chinese researchers has created pioneering low-carbon building materials influenced by Sandcastle worms. These revolutionary materials take cues from the earthworm, presenting the construction sector with a greener substitute for conventional building components. 

BIS research predicted that the low-carbon building materials market is expected to reach $578.85 Billion by 2032 from $244.96 Billion in 2022, growing at a CAGR of 8.69% during the forecast period 2022-2031. 

Greener path to Sustainability with Low-Carbon Building Materials

The development of these low-carbon building materials was inspired by the ingenious engineering of earthworms. Earthworms are known for their ability to burrow through soil with great efficiency, creating tunnels that improve soil aeration and drainage. Researchers from China's scientific community saw an opportunity to replicate this natural process in the world of construction. 

Worms build their burrows by mixing soil with their own secretions, creating a strong, stable structure. The Chinese team applied this concept to the creation of their innovative low-carbon building materials, which integrate sustainable practices with structural integrity.  

In 2022, the low-carbon construction material market was divided into segments based on material and application. Among these segments, metal comprised approximately 70.48% in terms of materials, while residential applications accounted for roughly 48.09% of the total low-carbon construction material revenue. 

Benefits for the Environment and Beyond

The low-carbon building materials developed by Chinese scientists offer numerous benefits for the environment and the construction industry.  

Reduced Carbon Emissions

Traditional construction materials, such as cement, are responsible for a significant portion of carbon emissions. The new materials reduce carbon emissions by using less cement, which is a primary contributor to greenhouse gases during its production. This is a significant step toward addressing the construction industry's impact on climate change.  

Enhanced Soil Quality

Just as earthworms improve soil quality by creating channels for air and water, these materials promote better soil health in construction sites. The materials contribute to improved drainage and aeration, reducing the risk of erosion and soil degradation.  


Using low-carbon building materials is not only eco-friendly but also economical. The reduced reliance on cement and other high-impact materials can lead to cost savings for construction projects.  


The new materials are versatile and can be used in various construction applications, from residential buildings to infrastructure projects. Their adaptability makes them a viable option for the industry.  

Recent Developments in the Global Low-Carbon Construction Material Market

As countries worldwide seek ways to reduce their carbon footprint and combat climate change, solutions like low-carbon building materials have become vital. Some recent developments in the low-carbon building materials market include:  

In Colombia, July 2023 saw Cemex, S.A.B. de C.V. celebrate a significant achievement with their Vertua net-zero carbon (CO2) concrete, surpassing 100,000 cubic meters in volumetric production.  

In July 2023, CarbonCure Technologies Inc. secured an $80 million investment in a new equity round, led by Blue Earth Capital, with additional backing from existing shareholders. This financial injection is aimed at supporting CarbonCure's mission to reduce and remove millions of metric tons of CO2 from the atmosphere annually.  

In September 2022, CarbonCure Technologies Inc. unveiled the CarbonCure Express EPD, a service enabling concrete manufacturers to measure the carbon impact of their products. This offering empowers them to strengthen their positions within the low-carbon and green building industry.  

In May 2023, SSAB AB initiated a partnership with BE Group, a steel service provider operating across Sweden, the Baltic States, Finland, and Poland. This collaboration involves SSAB AB assisting BE Group in identifying demands and opportunities for fossil-free steel in their key markets, including manufacturing and construction. Through this partnership, the two companies aim to address the technical, sustainable, and communication needs of BE Group's customers. 


According to Dhrubajyoti Narayan, Principal Analyst, BIS Research, “By adopting low-carbon construction materials, such as low-carbon concrete, builders and developers can contribute to mitigating climate change and meeting sustainability goals.”  

As the world witnesses the transformative impact of these eco-friendly building materials, it is evident that China's scientists have paved the way for a more sustainable and environmentally conscious future for the construction sector.
