New Technical Director for the Refining Division: Interview with Lorenzo Romualdi

It is with great pleasure that we announce Lorenzo Romualdi as the new Technical Director of Waste Facilities for the Refining Division. With extensive experience in the field and unwavering determination, Romualdi aims to elevate the Refining Division to the next level, focusing his efforts on effective waste management and operational optimization.

But what exactly is the role of the Technical Director of Waste Facilities (TDWF)? He plays a key role in ensuring that waste storage and treatment plants operate safely, in compliance with regulations, and with respect for the environment. The TDWF ensures that all operations comply with current waste management regulations; oversees the safety of workers and the surrounding environment by implementing preventive measures; prepares and executes emergency plans to handle critical situations such as accidents or hazardous material spills; and stays up-to-date on regulations and industry best practices through training and regular review of regulatory changes.

We had the opportunity to interview Romualdi to learn more about his plans and goals for the future.

What do you plan to implement in your new role as Technical Director of the Refining Division?

In my new role, I will primarily focus on overseeing the waste cycle in all its phases, ensuring compliance with established guidelines. To achieve this, I plan to concentrate on four key pillars: training, organization, communication and collaboration, and trust. It is crucial that all employees involved gain the necessary knowledge and understand the various issues and challenges related to waste management.

What goals have you set for 2024 and the years to come?

For 2024, our primary goal is to consolidate and optimize the management of incoming and outgoing waste at the plant, with a strong focus on safety and environmental protection. Additionally, we have just finalized a regulatory amendment that will allow us to increase our production capacity, and we are making progress in the design of new emission reduction and energy recovery systems. We are operating in a context of transition and business expansion, so it is crucial to face these challenges with determination and pragmatism.

What are the main challenges and opportunities that Valmet Refining is facing?

In addition to the importance of safe and environmentally-conscious management, the main challenge lies in digital transformation: transferring operational procedures and customary best practices into a computerized management system. This system will enhance traceability and reporting of the results achieved in waste treatment. Furthermore, we are planning future expansions and evaluating new projects to introduce different treatment methods to manage new waste streams that have become of interest following our integration into Legor Group. It’s a long and demanding task, both internally for our reorganization and externally in managing relationships with regulatory bodies and securing necessary authorizations. These challenges also present the greatest opportunities for growth and improvement.

Metal Recovery through the Stripping Plant

A Concrete Example of Circular Economy in Action

The stripping plant, designed for the removal of metals from the surface layer, was conceived in response to Valmet’s desire to qualitatively and quantitatively expand its metal recovery capabilities, while simultaneously embodying the circular economy paradigm. The idea is simple: economically and sustainably recover surplus inventory and production waste, using renewable energy, in a closed-loop system without consuming water and reintroducing all constituent materials back into the production chain.

Valmet Refining began developing this concept through a dynamic, versatile, and ever-evolving plant designed to improve itself year after year, both in production performance and in reducing consumption and environmental impacts.

Recovery Methods
There is widespread interest in recovering specific waste materials, such as fashion accessories coated with precious metals but composed internally of metals originally considered of lower value and later reevaluated by the same market, such as copper and its alloys (zinc and brass). For this reason, the stripping plant primarily processes materials from the electroplating sector, fashion industry, and bijou world, where surplus inventory, discarded products, test samples manipulated or damaged, and defective or imperfect items are sourced.

How It Works
Through a fully automated system, the precious external coating is separated from the substrate through chemical or electrochemical reactions and a washing phase. Afterward, the metals forming the matrix are ready to be reintroduced into the market. Thanks to the adoption of a management program with dedicated software, operators never come into direct contact with solutions and reagents during the various stages that enable metal recovery. Objects and precious surface metals exiting the process are stored in designated areas and then subjected to further refinement or direct re-entry into the market, depending on their type and composition.


Progress is being made on two fronts: the first is bureaucratic, aiming to obtain the end-of-waste (EOW) qualification for metals exiting the process. As explained earlier, these are valuable metals that do not fit the “waste” label, so legal tools are being utilized to bridge the gap between technological advancement and regulatory compliance. The other project aims to make the plant even more sustainable and self-reliant by sourcing water and energy from internal production and recovery.
