World Recycling Day: What Do We Do with Construction Waste?

On May 17th, “World Recycling Day” was celebrated, promoted by UNESCO with the goal of strengthening the 3Rs (Reduce, Reuse, and Recycle).

• Reduce: avoid the use of disposable materials and plan purchases and projects with criteria of durability and minimal waste.

• Reuse: give new opportunities to existing materials and products through repairs, donations, and exchanges before discarding them.

• Recycle: properly classify waste to ensure their entry into recovery and valorization chains.

This day aims to mobilize governments and citizens to minimize the volume of waste and prevent landfill overload and the overexploitation of natural resources.

Current Situation of Waste Management

According to the ‘Global Waste Management Outlook 2024’ report, prepared by the UN, in the last 30 years the amount of waste we produce has doubled, rising from around 1 billion tons per year to 2.2 billion tons. in Europe, construction and demolition works already represent more than the entire 30% volume of waste. If this trend continues, it is projected that 2050 by 2050, we will reach 3.3 billion tons.

• Construction waste: accounts for more than 30% of the total in Europe.
• Emissions avoided through recycling: each ton of processed plastic reduces up to 2 2 tons of CO2, and recycling paper is equivalent to saving 17 17 trees per ton.
• Household sorting: only 60% of households properly separate their waste.

Benefits of Implementing an Efficient Recycling System

A comprehensive waste of resource of waste management approach offers benefits that go beyond environmental impact. These include economic económicos savings and strengthening of community cohesion.

1. Environmental: conservation of natural resources and reduction of landfills.
2. Economic: energy savings and creation of green jobs.
3. Social: environmental education, community cohesion, and strengthening of corporate reputation.

How to promote recycling in construction?

To encourage recycling in construction, it is crucial to implement policies and regulations that promote sustainable practices, as well as specific strategies that facilitate their adoption in the industry’s day-to-day operations.

1. Education and training: provide education and training programs for construction professionals on recycling and waste management best practices. This may include seminars, workshops, and online resources that highlight the environmental and economic benefits of recycling in construction.
2. Financial incentives: establish financial incentives, such as grants or tax deductions, for businesses and construction projects that implement effective recycling practices. These incentives can help offset the additional costs associated with recycling and make it more economically attractive.
3. Regulations and standards: develop and enforce regulations and standards that require the separation and recycling of materials in construction projects. These regulations may include requiring a certain amount of materials to be recycled or documenting recycling efforts as part of building permit requirements.
4. Promoting collaboration: encourage collaboration between construction companies and local recycling companies to facilitate the proper disposal of recyclable materials and promote innovation in waste management. This may include the creation of networks and partnerships that facilitate the sharing of recycling resources and knowledge within the industry.
5. Recognition and certification: establish recognition and certification programs for construction projects that demonstrate a commitment to recycling and sustainability. Sustainability certifications, such as LEED, BREEAM, and EDGE, play a crucial role in setting standards and recognizing companies that adopt these practices. In doing so, they not only enhance their reputation but also help drive a culture of environmental responsibility throughout the industry.

By incorporating these strategies, the construction industry can move towards a more sustainable and responsible culture, where recycling materials is standard practice in all aspects of the construction process.

Towards a Zero–Waste Future

Last May 17th reminded us that waste management is not an optional matter, but a shared responsibility that requires commitment and continuous action. Adopt the 3Rs —Reduce, Reuse, and Recycle— and strengthen waste separation and recovery systems is the foundation for:

• Drastically reducing pressure on landfills and ecosystems.

• Saving energy and financial resources while creating green jobs.

• Fostering a culture of environmental responsibility across all sectors.

In the construction sector, these best practices translate into materials that re-enter the production cycle, cost savings on-site, and greater public recognition.
Additionally, environmental certifications such as LEED, BREEAM, or TRUE Zero Waste validate your efforts and position your project as a benchmark of sustainability.
