"We need to dream big, smarter and structure solutions to improve the world we live in. And as young leaders we have a responsibility to engage, educate and lead the future generations."

Julianne Endres

"Today, there’s a need for temporary shelters. What if Holcim could utilize its Strategy 2025 and provide these core humanistic necessities? With our ability to 3D Print, we can create easy-to-assemble particleboard panels for temporary housing."

Laura Golledge

Marie Couturier

Energy Analyst, France

"How can we attract and retain young talent and enable employees to make a tangible social impact? We could create a platform where students involved in a charity could ask Holcim for help in obtaining building materials and expertise from our employees."

Melanie Wong

Production Engineer S&P, Canada West

"To create a network of employees eager to take steps towards a more sustainable future, it’s important to take small steps for a big impact. My boldest idea is introducing the Green App to educate, motivate and inspire a more sustainable business."

"We recently launched Holcim Ideas Platform, about how we can leverage people by generating green electricity powered by footsteps."

Sara Chakir

Process and Environment Engineer, Morocco

"The limestone decarbonation process emits huge amounts of carbon dioxide, that can be captured and reused in other processes and industries. The excess of CO₂ that cannot be used could be stored in geological carbon sequestration. This way we might be able to reduce emissions by 50% and more."
