An LCA was performed on Stack and Combo

An LCA was performed on Stack and Combo
The recycled plastic version has less impact on the environment

LCA (Life Cycle Assessment) is an internationally recognised, analytical and systematic methodology (ISO 14040:2006, ISO 14044:2006) that assesses the environmental impact of a product or service throughout its life cycle.

Nardi has recently commissioned an LCA*, which compared Stack (Stack Mini and Stack Maxi) and Combo (Kit Combo High and Combo 60) furniture made from recycled plastic granules (included in its catalogue) with hypothetical ‘counterparts’ produced using entirely virgin plastic granules.**

The research, focused on calculating the CO2 equivalent generated by production processes, showed the following results:


It is evident that the furniture made from recycled plastic has a lower CO2 footprint of between 23 and 28%, confirming that working towards making production processes increasingly sustainable and continuing to invest in the Regeneration programme using recycled plastic are, indeed, conscious and strategic business decisions that benefit the health of our planet.

Through its research, Nardi intends to optimise the design of its outdoor furniture with a view to sustainability, so that the company is able to steer its choices towards systems that use fewer resources, thereby controlling and minimising direct and indirect environmental impact. All this is based on transparency and the continuous pursuit of improvement.

With regard to the company’s commitment to sustainability, Stack and Combo also received the Green Good Design Award 2022 and the Prize Designs for Modern Furniture and Lighting® Award 2022.


*The declared unit of the LCA is represented by 1 furniture unit (packaging included) made by Nardi S.p.A., within Cradle – Gate boundaries. The downstream stage was not taken into account within the in-house comparative system.

The time frame of the research covers the period from January 2023 to December 2023. The ECOINVENT 3.8 database and calculation methods were used to calculate environmental performance: CML baseline, USEtox, ReCiPe Endpoint(H) and Aware.


**For the researched products and the corresponding ‘virgin’ parts, the in-house comparative system is considered equivalent because:

The declared unit is the same

Production takes place within the same technological and geographical boundaries

The same life boundaries and exclusions are applied

The same databases and calculation algorithms are applied

No significant differences have been found in the waste generated between the current (regenerated) version and the hypothetical virgin material version. Likewise, energy and water consumption are considered comparable.
