Glass, paper and plastic are okay, but can we also recycle concrete, which makes a significant contribution to CO2 emissions?

It is in every corner of our daily lives and forms the city skyline. concrete recycling It’s not easy like the others.

Even though it seems like everything can be recycled, This is not easy to say for concrete.

Is it possible to recycle concrete?

Concrete recycling has become more important in recent years due to sustainable construction and greater environmental awareness. Britain is responsible for over a third of the waste produced in Europe. approximately 120 million tons annually The fact that waste is produced makes concrete even more important in this regard.

Reuse of concrete from rubble, which consists of resources such as cement, sand, gravel and water, especially for the protection of natural resources, energy saving and emphasizes the issues of reducing environmental impact.

Given all these reasons, concrete can of course be recycled, but this is no more than recycling plastic or glass. It’s not easy.

How is concrete recycled?

Concrete recycling process, the parts left behind after demolition It starts with breaking and grinding. This process also cleans metal rods or other materials mixed into the concrete. After being brought to a certain size, broken concrete pieces can often be used as filling material in new construction. Crushed debris; Substrate filling material in road construction, retaining wall, landscape gravel It can find a place for itself in areas such as.

In addition, recycled concrete is used in new concrete mixtures. total It can also be used as a food processor, which consumes fewer natural resources.

Benefits and challenges of recycling

The biggest advantage of recycled concrete is its contribution to the environment. Construction industry worldwide It has a significant share of CO2 emissions. Recycling concrete can reduce this percentage. However reducing greenhouse gas emissions It has little impact on the cement industry because most emissions occur during cement production.

Apart from this, reducing messes and Decrease in demand for natural stone quarries There are also additional benefits such as: But not everything is so rosy. In order to use recycled concrete in new constructions, it must pass many tests, such as durability and strength.

This testing and processing process can increase costs. Hence the usability of recycled concrete in projects also depends on economic factors stays.

Innovations in concrete recycling

Developments and new technologies in the field of concrete recycling promise to make this process more efficient. Especially types of concrete that increase the absorption of carbon dioxide and recycled materials cement technologies takes a step towards sustainable construction.
