When we talk about sustainability in industry, we often think of product recycling. But there is another equally strategic lever: making the process itself more efficient<\/strong>, especially in intensive stages such as wood drying<\/strong>, where gases and water vapour are generated.<\/p>\n\n\n\n

At Finvalia, this line of work focuses on a simple but powerful idea: making use of what is currently lost in order to reduce resource consumption and, in addition, explore the recovery of compounds with potential added value.<\/p>\n\n\n\n

Why is drying an opportunity?<\/h3>\n\n\n\n

Drying does not only consume energy. It also generates gas streams containing water vapour<\/strong>, which can be recovered, as well as other components originating from the wood<\/strong>. These are present in low concentrations, but are relevant from both a technical and market perspective.<\/p>\n\n\n\n

At the Finvalia 2025 event<\/a>, emphasis was placed on the fact that efficient water use goes beyond environmental concerns. It is also a strategic factor<\/strong> in a context of growing scarcity and increasing regulatory pressure, which may affect future production capacity.<\/p>\n\n\n\n

Two complementary approaches within Finvalia<\/h3>\n\n\n\n

Within Finvalia, the recovery of vapour<\/strong> linked to drying is addressed through two mutually reinforcing lines of work:<\/p>\n\n\n\n

1) Recovering water for reuse in processes<\/strong><\/p>\n\n\n\n

The first objective is clear: to recover this water so that it can be used again in operations. This requires one key condition: recovering it at a quality suitable for use, for example in steam production.<\/p>\n\n\n\n

The aim is to capture the water under conditions that allow it to be safely and efficiently reintegrated into the process.<\/p>\n\n\n\n

2) Using this recovery process to extract high added-value compounds<\/strong><\/p>\n\n\n\n

The second approach opens the door to high-impact circularity: recovering wood-derived compounds present in these drying gases, which may have potential market value.<\/p>\n\n\n\n

Here, the work is being approached progressively and realistically:<\/p>\n\n\n\n
