The recent publication of the Global Waste Index 2025 places Spain in 27th position among OECD countries in terms of waste management. This ranking highlights an urgent need to advance toward more sustainable models, particularly regarding elandfill reduction and the promotion of more efficient treatment technologies.

In this context, Kalfrisa positions itself as a strategic ally for improving these indicators, thanks to its expertise in thermal technologies for waste treatment and waste-to-energy.

Alternatives to landfills: energy recovery as a solution

According to the report, Spain continues to send more than 220 kg of waste per capita to landfills each year, one of the most penalized methods due to its environmental impact and low efficiency in the waste hierarchy. In response to this issue, waste-to-enerty through the controlled thermal treatment of waste offered by Kalfrisa allows:

  • Drastically reduce the volume of waste sent to landfills
  • Prevent greenhouse gas emissions generated by decomposition in landfills
  • Harness the energy potential of non-recyclable waste, generating useful energy for industrial processes or district heating networks

These solutions align with the best practices recommended by the Global Index and the European Union’s circular economy guidelines.

A specialized approach for each type of waste

Kalfrisa designs and installs energy recovery and valorization machinery tailored to each client and type of waste. Its technology enables the effective thermal treatment of:

  • Hazardous industrial waste
  • Non-recyclable municipal solid waste
  • Liquid and slurry waste
  • Medical and healthcare waste

Each project is developed under strict criteria of energy efficiency, environmental safety, and European regulations, providing a sustainable solution where recycling is not feasible.

Towards a more circular future

Although recycling remains a priority, the Global Waste Index recognizes the value of thermal treatment with energy recovery as a more sustainable solution than landfilling. In this context, Kalfrisa actively contributes to:

  • Closing the waste loop.
  • Boosting energy self-sufficiency.
  • Reducing the carbon footprint of Spain’s waste management system.

In this way, Kalfrisa reinforces its commitment to the transition toward a circular, low-carbon economy, positioning itself as a key player in improving the country’s environmental performance.
