Reflect, Inspire and Change With Our Guest Speakers for Earth Day 2024


Held on April 22, Earth Day is an important day to raise awareness and reflect upon our shared responsibility for the environment. It’s also a chance to celebrate those in our community who are leading the way with initiatives, outreach and new technologies. In 2024, the theme is on reducing plastics, with a goal set to achieve a 60% reduction in the production of all plastics by 2040.


Here at ICMI, we’re proud to feature a diverse range of sustainability pioneers and advocates who can make this year’s Earth Day special at your organisation with  inspirational stories and invaluable insights. 


Laureate Professor Veena Sahajwalla


An internationally recognised materials scientist, engineer, and inventor responsible for revolutionising recycling science, Professor Veena Sahajwalla is the perfect speaker for this year’s Earth Day theme. She has pioneered the production of new ‘green materials’ including inventing polymer injection technology that allows for the eco-friendly recycling of tyres in steel production, known as “green steel”.

Josh Howard

Single Use Ain’t Sexy makes it easy for people to reduce the amount of single-use plastic going into landfill with innovative “Just Add Water” soap tablets provided alongside a reusable glass bottle dispenser. With a passion for preserving the planet, he makes for a great keynote speaker.
