Technical Certification
Contaminated industrial sites are both an environmental burden and a hidden economic opportunity. Existing remediation methods are extremely costly, while most recovery technologies depend on chemical processes that fail to meet environmental standards.
EcoGravity changes the paradigm with certified gravity-based technology. Our mobile systems clean contaminated soil and recover valuable metals in a single process — without chemicals — turning waste into value while meeting modern environmental requirements.
Our patented gravity-based system removes contamination while recovering valuable metals — without chemicals. Designed for mobility and efficiency, EcoGravity delivers real-world results for both environmental cleanup and resource generation.
Millions of tons of contaminated soil and industrial waste lie across Europe, harm ecosystems, and create long-term liabilities. Traditional remediation methods are either too expensive or rely on inefficient processes that fail to recover value.
EcoGravity introduces a patented gravity-based technology that removes heavy metals from contaminated soil without chemicals. The system is mobile, energy-efficient, and designed for real-world scalability — transforming waste into clean, reusable material.
We go beyond remediation. EcoGravity recovers valuable metals such as gold, silver, and copper, turning environmental problems into profitable resources. This creates a sustainable model where cleanup generates revenue, not just costs.
Combining gravity with engineered mechanical systems, we deliver reliable and efficient material separation across all conditions, maximizing recovery potential while reducing losses and adapting to a wide range of material inputs.

Density-based sorting removes heavy metals without chemicals — pure physics at work.
System parameters can be precisely adjusted for each material type, ensuring optimal performance and efficiency.
Our processing unit is fully mobile, deployable directly to contaminated sites anywhere.
Closed-loop water system minimizes consumption and eliminates wastewater discharge.
A streamlined five-step process from contaminated input to clean, reusable output.
Contaminated soil or industrial waste is fed into the processing system.
Density-based gravity separation isolates heavy metals from clean material.
Valuable metals (Au, Ag, Cu, etc.) are concentrated into a polymetallic product ready for direct sale.
The remaining material is transformed into classified mineral fractions, suitable for direct use as construction aggregates.
Process water is filtered and recirculated in a closed-loop system.
EcoGravity performs the recovery, separation, and decontamination of materials through a gravity-based mechanical process, using water recirculation in a closed-loop system and integrated material washing.
Following processing, the resulting fractions are:
Beyond separation, the process enables the direct reuse of resulting materials.
The 2–15 mm fraction and 15–60 mm fraction consist of granular materials suitable for use as construction aggregates (ballast, concrete preparation, and structural applications).
The 0–2 mm inert soil fraction represents fine material which, following separation and laboratory validation, can be considered non-contaminating and suitable for reintegration or reuse.
The 0–2 mm polymetallic fraction contains concentrated heavy metals (Au, Ag, Zn, Cu, Pb) and is collected separately for analysis and further valorization.

Using engineered mechanical systems and density-based sorting, EcoGravity separates heavy fractions from lighter material without chemical treatment.
The process delivers concentrated valuable fractions, reduces contamination, and supports the production of reusable mineral outputs through a closed-loop approach.
EcoGravity combines environmental remediation with real material recovery — turning contaminated material into valuable resources through a simple, efficient process.
EcoGravity doesn’t just clean materials — it extracts valuable heavy metals, transforming waste into a usable and profitable resource
The process uses only gravity and mechanical systems, with no chemicals involved and a closed-loop water system that minimizes environmental impact.
The system is fully mobile and operates directly on-site, eliminating transport costs and reducing overall operational expenses.
EcoGravity is validated through independent certification, laboratory testing, and real-world industrial pilot operations.
EcoGravity has undergone independent technical evaluation through ICECON, confirming compliance, operational safety, and validated performance under controlled testing conditions.
Independent laboratory analysis confirms high recovery rates for valuable metals, including gold, silver, copper, and heavy metals such as lead and zinc, across multiple tested material samples.
Pilot operations demonstrate consistent performance in real industrial environments, confirming scalability, operational stability, and strong commercial viability.
EcoGravity operates without chemical treatment, using a closed-loop water system and mechanical processes that minimize environmental impact and support compliance.
