The soil-washing plant with ReSoil® technology was constructed in city of Prevalje which sits in a contaminated area of Meža Valley, Slovenia. The mission of this facility is to prove the scalability of ReSoil® technology. With the capacity of 6 t/day (1,500 kg per batch) it enables demonstrational remediation of local sites as well as demonstration of ReSoil® technology to stakeholders. The Technology Readiness Level of plant operation is TRL 7 (EU, NASA methodology).
The permit for construction of this soil washing plant was granted by Slovenian Environmental Protection Agency in 2017. The permit was based on proofs of ReSoil® closed process cycles operation and zero-emissions. Construction of the plant was co-financed from EU LIFE + Programme with 50% contribution of 1.1 M EUR. The operating permit for this soil-washing plant was obtained in July 2018. The ReSoil® technology uses common process equipment such are sieves, mixing vessels and filter presses. The remediation process can be controlled manually and the innovative part of ReSoil® technology, i.e. in press soil rinsing, EDTA and process water recycling, can also be controlled automatically by the SCADA (supervisory, control and data acquisition) system.
Small mobile ReSoil®plant (up to 300 kg of soil / day) was constructed in mobile containers for POSIDON PCP H2020 project. In this way we were able to investigate the future lay-up of the machinery, installations, and realistically simulate ReSoil® working process. The demo ReSoil® plant enables 3 soil remediation batches per day with the average time for single remediation batch less than 3h. ReSoil® technology does not generate wastewaters and other emissions, and preserves soil quality and soil properties as plant substrate.
The ReSoil® trailer - a mobile pilot unit is a compact system mounted on a car trailer, enabling easy transport and rapid deployment at different locations. It is designed for technology demonstration and feasibility testing, allowing verification of performance under real-world conditions.
Key specifications:
Capacity: 5 kg of soil per batch
Purpose: on-site technology presentation and feasibility testing
The main advantage of the unit is its mobility, which allows the process to be demonstrated directly to end users and stakeholders. The unit was developed in close collaboration with professional electricians, metalworkers, and mechanical engineers, ensuring high technical quality, reliability, and operational safety.
To support early-stage technology evaluation, we offer a simple and practical model that includes:
- laboratory testing on small soil samples (~0.5 kg) to assess the removal efficiency of metals and metalloids;
- and on-site feasibility demonstrations using the mobile unit (5 kg per batch, up to ~50 kg per day), enabling testing under real conditions and direct stakeholder engagement.
