Concrete and its devastating impact on the environment

Concrete and its devastating impact on the environment

When people consider what is the most consumed product on earth, few would consider concrete. In fact, concrete is the second most consumed product on Earth, second to water1. It is used as the foundation for most of our modern building infrastructure – houses, tower blocks, roads and bridges. As a material, it is cheap to produce, incredibly strong and very versatile. In the world today, concrete is used in 80% of modern construction.

However, the use of this versatile material has a big impact on the environment. The environmental toll is a result of its production. During concrete production, carbon dioxide is produced as a result of burning fossil fuels to produce the heat needed for the cement producing process and also from the thermal decomposition of calcium carbonate in the process of producing cement clinker. As a result, it is thought that concrete production is responsible for approximately 8% of all the worlds’ carbon dioxide emissions2.

As part of moving forward to a more sustainable way of living, one of the biggest challenges we face is finding an alternative to this sturdy, inexpensive material that modern day society relies upon.

In recent years, a number of studies have looked into what alternatives are available and also how the current concrete production process can be improved to produce less CO2. These include reducing the amount of binder, as disclosed in this US patent application US 2022/017419, or substituting some of the concrete with more environmentally friendly additives such as agricultural waste products, as disclosed in this Chinese patent application CN 104478361. Other alternatives include utilising co-products or by-products of cement as partial replacements of cement, as disclosed in US 2012/111236, and recycling discarded water that is used in the concrete production process3, such as in CN 211513726. However, there is still a lot more work that needs to be done to improve the process and, ideally, identify a replacement material that is as versatile and hard-wearing as concrete.

Intellectual Property offices around the world realise the need to encourage the innovation of new products and processes related to clean technology, as well the need for improvements to current materials and methods of production, including concrete production. A number patent offices around the world have launched schemes which allow applicants who file patent applications directed to green technology, or environmental improvements to current processes, to request fast-tracked prosecution.
