In addition to the implementation of fixed facilities, we will also consider the possibility of on-site treatment using portable configurations such as trucks, depending on the project conditions. This will facilitate gradual demonstration and application considerations while integrating with existing treatment routes, even in cases where the transportation burden or on-site constraints are significant. Furthermore, in addition to the treatment itself, we will also incorporate a resource recycling perspective, including the effective use of by-products, and consider the possibility of process design with an eye toward future recovery and reuse. For example, we will organize the overall design, including the recovery and reuse of harmless mixed gases generated during the treatment process and the potential use of hydrogen, with an eye toward post-treatment. HELIX Environmental Development will develop an overall design that includes not only treatment performance but also legal and safety requirements, operational structures, installation conditions, integration with existing routes, and practical workflows, with the aim of implementing it in a form that can be used on-site. Because this is a challenging target, we will propose it as a realistic option that can be verified and applied in stages while integrating with existing treatment infrastructure.
