Product description

The HELIO-SOLAR Vitrification Process is a groundbreaking green technology that revolutionizes waste management and sustainable construction. By harnessing the power of concentrated solar energy through innovative solar-thermal technology, this process can reach temperatures of up to 4,000 °C without the need for combustion or traditional fuel sources.

Through this solar heat, non-recyclable mineral waste, industrial sludge, and toxic by-products are thermally vitrified into inert glass-like materials such as slag and obsidian. These materials can then be utilized as low-carbon construction aggregates or silicates in concrete, offering a sustainable alternative to traditional building materials.

The key innovation of HELIO-SOLAR lies in its ability to eliminate harmful emissions, reduce landfill waste, and produce materials with exceptional structural and chemical stability. This process not only addresses the environmental impact of industrial waste but also contributes to the circular economy by repurposing manufacturing by-products into valuable resources.

Key characteristics and environmental benefits

  • Utilizes concentrated solar energy for ultra-high temperature vitrification
  • Transforms non-recyclable waste into inert glass-like building materials
  • Reduces emissions, landfill waste, and reliance on fossil fuels
  • Enables sustainable construction practices with low-carbon aggregates
  • Facilitates resource recovery from industrial by-products
  • Scalable deployment options from pilot units to industrial furnaces
  • Generates hydrogen and steam for industrial heat needs
  • Promotes net-zero energy input and high-value material production

About the Company

Heliosand is a French industrial cleantech startup founded in 2020 in Lyon. The company uses patented solar concentration technology based on Fresnel lenses to reach temperatures of up to 4,000 °C. This enables recycling of mineral and industrial waste—including hazardous sludge and non-recyclable materials—into inert, high-value construction materials like slag, activated silica, and obsidian. The process replaces conventional fossil-fueled furnaces, offering a zero-carbon alternative for heat-intensive industries. Heliosand’s innovation supports circular economy and decarbonisation by turning pollutants into building-reuse resources. With prototypes validated and pilot operations underway since 2024, the company aims to scale commercial deployment through industrial partnerships and expansion across European industrial zones. Heliosand contributes to multiple UN Sustainable Development Goals, particularly affordable clean energy, industrial innovation, responsible consumption, and climate action.
