How can innovative design help structural engineers contribute to the circular economy?

1 Design for durability

One of the main objectives of the circular economy is to extend the lifespan of products and materials, and to minimize the need for maintenance and replacement. Structural engineers can design for durability by choosing materials that are resistant to corrosion, fatigue, and degradation, and by applying protective coatings and treatments. They can also design structures that can withstand natural hazards, such as earthquakes, floods, and fires, and that can adapt to changing loads and conditions. By designing for durability, structural engineers can reduce the environmental and economic costs of repairing and rebuilding structures, and preserve the value of the resources invested in them.

3 Design for recyclability

A third objective of the circular economy is to recover and regenerate the materials and energy used in products and systems, and to prevent them from becoming waste or pollution. Structural engineers can design for recyclability by selecting materials that can be separated, sorted, and processed into new products or materials, or that can be biodegraded or composted. They can also design structures that can be easily dismantled, deconstructed, or disassembled, and that minimize the use of adhesives, coatings, or additives that hinder recycling. By designing for recyclability, structural engineers can reduce the environmental and health impacts of waste disposal and landfilling, and conserve the natural resources and energy used in production.

Innovative design is a powerful tool for structural engineers to contribute to the circular economy, and to create structures that are more sustainable, resilient, and valuable. By applying the principles of design for durability, adaptability, and recyclability, structural engineers can optimize the use and reuse of resources, and create positive impacts for the environment, the economy, and the society.
