An Analysis of Carbon Footprint Sensitivity to Recycling Content of High-Performance Turbomachinery Components Applying Circular Footprint Formula (CFF) 

The fight against Global Warming and Climate Change, in the UN Agenda 2030 scenario, has made clear the need of a more sustainable industrial design as part of a Sustainable Product Development (SPD) process. Aiming to define new products considering environmental impact as a main design driver, engineers can leverage on different design aspect like material selection, mechanical configuration, maintenance requirements and recyclability.

Material selection can be of focal importance in reducing the Carbon Footprint of a new product in the field of turbomachinery, due to the large use of metals, rare earths, and alloys. These are materials that can be produced using a certain recycled content and can go back for recycling to the foundry at the End of Life (EoL).

In this work, an assessment of Carbon Footprint (CF) sensitivity on recycled content in a turbomachine component is proposed, applying the Circular Footprint Formula (CFF) methodology proposed by the European Commission.

The presented case study refers to a set of components of high-performance turbomachinery designed with state-of-the-art methodologies and tools, in particular a component of a Gas Turbine, of an Axial Turboexpander and of a Centrifugal Compressor were analyzed to assess the effect on carbon footprint of recycling different metallic material types, varying from super alloys to steels.

Presenting Author Biography: Luca joined Nuovo Pignone in 2001 as design engineer in the Gas Turbine (GT) Engineering department. After three years he moved to Centrifugal Compressor (CC) Engineering Dept. where he built his career.

In the 12 years spent in this department, he covered different managerial positions with increasing responsibilites up to cover the position of manager of the teams in charge of the mechanical design for Centrifugal Compressors and Turbo-Expander machines.

In 2016, he moved to a position of single contributor becoming the focal point of all the cost-out activities of his organization. In this role, he worked in close cooperation with different people inside the company (buyers, PM, MFG engineer etc..) in order to identify any chance to reduce costs. Furthermore he also joined in the building and optimization of the Cost Models used in ITO to price the Centrifugal Compressors.

Since 2020, in addition to his current role, he is the responsible of the introduction of the e-LCA methodology inside his organization. In close collaboration with Engineering University of Florence and doing bench-marking with other Engineering office where this methodology was already introduced, he built the first work for a CC comparing two different MFG technologies for an impeller. In progress, under his guide, there are two different collaborations with Florence University to extend this kind of analysis to an entire CC and to a complete compression train.
