Homeward Bound Expedition

Marta is a professional engineer with over 17 years of experience in photovoltaic (PV) solar technology at ACCIONA. She studied Agricultural Engineering, holds a Master’s degree in Environmental Science, and is certified as a Project Management Professional (PMP®) by the Project Management Institute (PMI). She completed her studies by collaborating with an NGO in a disadvantaged area of the Peruvian Andes on a global project focused on agriculture, livestock, and health with the shared goal of addressing the growing issue of child malnutrition in the region.

Marta has built her career working in various departments, including Business Development and Engineering & Construction. Over the last 10 years, she has dedicated herself to the Energy Resources Department, conducting energy assessments and designing optimized photovoltaic plants worldwide. Her work involves staying up to date with cutting-edge technology and assessing potential meteorological risks in different regions (floods, hurricanes, etc.). She strongly believes in renewable energy and its responsible use.

Currently, Marta analyzes both Utility Scale plants and distributed generation systems (on- and off-grid), as well as hybrid plants, which simultaneously use multiple renewable resources (wind, solar, hydro, storage, green hydrogen, etc.).

María is a Civil Engineer (specializing in Roads, Canals, and Ports) from the Polytechnic University of Madrid, with 20 years of professional experience at ACCIONA. Throughout her career, María has played a key role in numerous large-scale projects, standing out for her strong leadership skills and commitment. Currently, she serves as Contract Manager for ACCIONA’s Spanish projects. Her expertise and strategic vision are essential to the success and evolution of projects aimed at minimizing environmental impact and optimizing infrastructure resources.

An Environmental Biologist and Environmental Scientist (UAM), Edith Guedella is a renowned professional passionate about sustainability and circularity, with nearly 20 years of experience in developing sustainable solutions for infrastructure construction. She currently serves as Head of Sustainability for ACCIONA’s Construction business, where she coordinates the implementation and alignment of all global sustainability projects.

Edith has worked as a researcher and innovation manager, has been recognized as an expert evaluator by the European Commission in innovation programs such as H2020 and Horizon Europe, and has participated in various national and international standardization working groups related to sustainability in construction and circularity.

Committed to transforming the construction sector towards a more sustainable model, she is a member of the Advisory Board for the Master’s in Circular Engineering at the Carlos III University of Madrid and was selected to participate in the "From Linear to Circular" program by the Ellen MacArthur Foundation.

She specializes in environmental impact assessment with a focus on lifecycle analysis and has contributed as an expert to several standardization committees on sustainable practices in construction. Edith is a member of Women Action Sustainability (WAS), where she also collaborates with the working group on circular economy. She has mentored through programs by WAS, the Princess of Girona Foundation, and the Quiero Trabajo Foundation.

Additionally, she is part of AMIT-MIT, the UCLA Spain alumni association, and the FIDIC TG23 working group for drafting Net Zero Contracts. She is also a steering committee member for the Fast Infra Sustainable Label, a certification system for sustainable infrastructure assets. Lastly, she is part of the eighth cohort of the Homeward Bound leadership program for women in STEMM, which will take her on an expedition to Antarctica in January 2025.
