Reducing construction waste with offsite building

The construction sector produces a significant amount of waste, generating around 62% of the UK’s total output. This includes materials such as bricks, insulation, glass and gypsum – all of which are typically unavoidable when working on large-scale construction projects.

With sustainability a priority on everyone’s agenda, what can be done to reduce the waste from the construction industry? One solution, that we of course champion, is the use of offsite building. The nature of modular or prefabricated buildings means that using them vastly reduces site waste outputs in comparison to the traditional construction methods. Modules are engineered precisely and the materials can be re-used or recycled, helping create a circular economy in construction.

In celebration of Zero Waste Week, let’s take a look at all the ways that modular building can help reduce construction waste and lower carbon emissions.

Precision manufacturing

Modular buildings are manufactured offsite, meaning that they are produced inside a controlled factory environment and to precise specifications as per the needs of each project.

Our offsite method reduces waste at every stage of a build. As we manufacture each module to order, the materials used for each project are either repurposed within production or recycled responsibly, creating fewer offcuts or waste parts and limiting the energy required to cut materials into the correct shape or size.

Since 2024, our factories have sent zero waste to landfill – 66% of our waste is recycled, and 34% is converted to energy, keeping the process as sustainable as possible.

Using materials sustainably

We’ve already mentioned how we repurpose or recycle our materials during the modular production process, but how do we achieve this? A simple solution is by choosing materials that are 100% recyclable or reusable, which offers both durability and flexibility to our builds as well as making sure materials are sustainable.

Steel is used as the framework for modular buildings and can retain structural integrity even when repeatedly reused. It can also be recycled infinitely without impacting its quality, further reducing its carbon footprint. Another frequently used material in offsite manufacturing is timber. Using a sustainably sourced timber is a green alternative to materials like concrete that use a large amount of energy in production.

Reuse and repurpose

We design our rental products with quality in mind, making sure that they are built to last and can be repurposed as and when needed. This can happen on average 12 times over the course of their ~40-year lifespan, significantly minimising waste.
