Investing in the efficient management of resources through circular economy projects, ensuring the conscientious and responsible use and preservation of resources.

Circular Economy

Reduce, reuse, recover and recycle materials or energy. This is one of the basic concepts of the circular economy that Altri is exploring in several areas of the Group.

Altri, as a creator of renewable products, applies the circular economy throughout its value chain - from its sustainably managed forests, through the pulp production process to the way it reuses all by-products.


1. Renewable resources

Altri uses wood produced in sustainably managed forests. Residual forest biomass is energetically valued in biomass boilers.

2. Responsible operations

Altri works in order to obtain maximum operational efficiency in its industrial units, reducing its environmental and social impact.

3. Sustainable products

All its products are sustainable. Renewable and biodegradable.

4. Product uses

5. Circularity at the end-of-life

When it is no longer possible to reuse or recycle, forest-based products are energetically recovered, replacing fossil fuels.

Environmental management at Altri’s industrial units

All pulp and energy industrial units scrupulously comply with the limits defined in their Unique Environmental Titles (UET), in line with the recommendations in the Best Available Techniques (BAT), of the European Union reference documents.

Waste production increase in the energy production activity at GREENVOLT is related to the start of operation in July 2019 of the Sociedade Bioelétrica do Mondego plant.

The main raw material used by Altri in the pulp and dissolving pulp manufacturing process is wood, which comes from sustainably managed plantations. The non-renewable materials used, which represent the remaining 4%, are chemicals such as caustic soda, hydrogen peroxide, sulfuric acid and sodium chlorate.

At Altri, about 96% of the raw materials used are renewable
