Building a greener future with recycled construction materials

The construction industry needs to embrace recycled materials as a way to minimise waste and environmental impact.

Concrete and Aggregate from Demolished Structures

Concrete and aggregate from demolished structures are valuable resources that can be recycled and used in various construction projects.

Recycling concrete involves crushing old concrete from demolished structures into smaller pieces, which can then be used as recycled aggregate in new concrete mixes.

This process not only helps reduce the amount of waste going into landfills but also conserves natural resources by reducing the need for virgin aggregates.

The use of recycled concrete in building projects can help lower costs and decrease environmental impact by reusing materials that would otherwise end up as waste. Additionally, recycled concrete often performs as well as or even better than traditional concrete.

Recycled Steel and Metals

Recycled steel and metals play a crucial role in sustainable construction practices, offering a range of benefits to both the environment and the construction industry. By utilising recycled steel and metals, such as scrap metal from old buildings or discarded machinery, builders can significantly reduce the demand for raw materials, lower carbon emissions, and decrease waste sent to landfills.

The process of recycling steel involves melting down existing steel products to create new ones, which requires less energy compared to manufacturing virgin steel.  

Using recycled metals can contribute to sustainability certifications (for instance, LEED) showcasing a commitment to eco-friendly building practices. The versatility of recycled metals allows for innovative design possibilities that combine aesthetic appeal with functional efficiency.

Plastic Composites from Recycled Plastics

Recycled plastics have become a popular option in the furniture industry and are also increasingly being used in construction. These composites are created by combining recycled plastics with other materials to form a strong and resilient product suitable for different construction applications.

While not always following the same production processes, it’s common for recycled plastic to be made by utilising post-consumer plastics that would otherwise end up in landfills or oceans. Plastic composites offer an innovative solution to the challenge of managing plastic waste while providing a viable alternative to traditional building materials.

One of the primary benefits of using plastic composites from recycled plastics in construction is their resistance to rot, mould and insect infestations. This makes them ideal for outdoor applications such as decking, fences, and cladding where exposure to moisture and pests is common.

Plastic composites can be moulded into different shapes and sizes, allowing for a wide range of design possibilities in both residential and commercial projects. With advancements in manufacturing processes and material technology, recycled plastic composites now come in a variety of colours and textures that can mimic natural wood or stone finishes.

Innovation is also growing with recycled bioplastics and bio-composite materials, where the added materials are derived from natural sources.

Glass and Recycled Glass Products

Glass is a versatile material that can be recycled and repurposed in a multitude of ways. In the construction industry, recycled glass is commonly used to manufacture glassphalt, which is a type of asphalt concrete mixture that incorporates recycled glass aggregate.

The use of recycled glass in construction extends beyond paving materials to include decorative elements such as countertops, tiles and architectural features.

By incorporating recycled glass into building design, architects and designers can create visually striking spaces while promoting sustainability through the use of reclaimed materials. Recycled glass tiles offer a sustainable alternative to conventional ceramic or stone tiles, adding character and charm to interior spaces.

Innovations in manufacturing processes have led to the development of high-performance recycled glass products that meet stringent quality standards for use in construction projects. From energy-efficient windows made with recycled glass to insulation materials derived from post-consumer sources, the range of applications for recycled glass continues to expand.

With advancements in technology driving the production of new materials derived from recycled sources, architects and builders have access to a diverse selection of eco-friendly options for creating environmentally responsible structures.

Wood and Reclaimed Timber

Wood and reclaimed timber are a popular choice both for the environmentally friendly nature and unique aesthetic appeal. Reclaimed timber is in essence wood salvaged from old buildings that are no longer in use.

This wood is then repurposed for new construction projects, reducing the demand for virgin timber and minimising the environmental impact of deforestation. Reclaimed timber is known for its character and charm, with each piece telling a story of its previous life through its weathered appearance and patina.

In addition to its sustainability benefits, reclaimed timber also offers practical advantages in construction. Due to its age and seasoning, reclaimed wood is often more stable and less prone to warping or twisting compared to newly harvested lumber.

This can result in a more durable and long-lasting building material that requires less maintenance over time. Furthermore, using reclaimed timber can contribute to LEED (Leadership in Energy and Environmental Design) certification for green building projects by promoting resource conservation and sustainable practices.

One of the most common applications of reclaimed timber in construction is for flooring, panelling, beams and furniture. The unique grain patterns and rich colours of reclaimed wood add warmth and character to interior spaces, creating a sense of history and authenticity.

In exterior applications, reclaimed timber can be used for siding, decking, fencing, or pergolas.

La Crêta Farmhouse shows us the art of taking away

The most profound thing Bard Yersin did to this 18th-century Fribourg farmhouse was strip away layers from an earlier renovation. La Crêta is an adaptive reuse project that proves sustainable design’s most powerful tool is restraint.

Reviving a wounded mill: Ennenda Mühle is restitched with care

At a former medieval mill in Ennenda, Switzerland, Atelier Lando Rossmaier begins with careful deconstruction, peeling back layers to reveal and renew the building’s original structure. The adaptive reuse project rebuilds the house using materials sourced within roughly ten miles, including local timber, lime and hemp-lime walls that help regulate moisture in the ageing masonry. Through this restrained approach, the once-abandoned mill is revived as a home and goldsmith’s workshop while preserving the character of its historic fabric.
