The Latest




We are thrilled to announce that Manuel Benitez Ruiz, founder of Plantaer, is the newest recipient of 1000 Gretas $1,000 grant. Manuel’s innovative approach to integrating nature with urban infrastructure promises to transform our cities into sustainable ecosystems. Learn more about his groundbreaking work at www.plantaer.com and connect with him on LinkedIn.

Inspired by Nature, Driven by Innovation

Manuel’s journey began with a frustration rooted in his civil engineering background. He was disheartened by the absence of nature-based solutions in construction. This led to a revolutionary idea: growing plants on concrete, the most utilized resource globally after water. Once he demonstrated the feasibility of this concept, Manuel recognized its immense environmental potential for urban areas and humanity at large. With a vision for a greener future, he took it upon himself to turn this idea into reality, rather than waiting for someone else to take the lead.

Vision for a Greener Future

Manuel envisions cities transformed by living concrete technology into vibrant, sustainable ecosystems. Imagine urban landscapes where buildings and streets are alive with plants, purifying the air, reducing heat, and enhancing biodiversity. By embedding organisms into our infrastructure, Plantaer aims to turn urban spaces into active contributors to sustainability, effectively lowering carbon footprints and capturing CO2.

With this technology, people will have the opportunity to choose building materials based on the plants that resonate with them, fostering a new era of vibrant, resilient cities where humans and nature coexist harmoniously.

Revolutionizing Construction with Biodiversity-Supporting Building Materials

Plantaer is set to revolutionize the construction industry by introducing building materials that support biodiversity. This innovative approach not only addresses the pressing need for sustainable urban development but also paves the way for a future where our cities contribute positively to the environment.

We're thrilled to announce our newest grantee, Letsile Bogadi, and her innovative company, Nanobig Solutions!


Letsile's journey into sustainability began with a realization: waste is not just a problem but a potential opportunity. Drawing on her background in Materials and Nanochemistry, she embarked on a mission to transform waste into valuable materials, particularly focusing on Nanomaterials for water treatment.


At a recent sustainability conference, Letsile highlighted the urgent need to address waste as a significant contributor to climate issues. Her vision is clear: by harnessing waste as a resource, we can not only mitigate environmental harm but also create added value. Her call to action reflects her dedication to collaboration, seeking connection with an R&D institution equipped with electrospinning capacity.



When asked about the future her innovation could bring, Letsile paints a hopeful picture. She envisions a world where no biomass is wasted, thereby eliminating associated greenhouse gas emissions. Moreover, her innovative solutions promise to reduce both the energy and financial costs of water treatment. This, she believes, will empower nations with limited economic resources to thrive despite the challenges posed by climate change.

Join us in celebrating Letsile Bogadi and Nanobig Solutions as they pave the way towards a cleaner, more sustainable future. Together, we can turn challenges into opportunities and make a lasting impact on our planet.


Stay tuned for updates on Letsile's groundbreaking work and how you can get involved in supporting her vision. Together, let's build a brighter tomorrow.

We are thrilled to announce the latest recipient of the 1000 Gretas grant - Blazin' Joe, a company founded by the dynamic Maddie Cataldo. Maddie's journey in environmental entrepreneurship, sparked by her father's biodiesel company, has led to the creation of a revolutionary solution to repurpose spent coffee grounds.



A Passion for Sustainability:

Maddie's childhood exposure to her father's biodiesel company fueled her interest in upcycling for the environment. This passion guided her to major in sustainability and entrepreneurship at CU Boulder, where she discovered the potential of entrepreneurship to create positive change.


Blazin' Joe's Mission:

Blazin' Joe is on a mission to transform the way we view and discard spent coffee grounds. Recognizing the environmental impact of coffee grounds in landfills, Maddie and her team have developed an ingenious solution - turning coffee waste into all-natural firelogs and fire starters.


Eco-Friendly Fire Products:

Blazin' Joe's firelogs and fire starters burn hotter than traditional wood, providing a long-lasting warmth perfect for indoor and outdoor use. Free from harmful chemicals, these products offer a delightful, eco-friendly alternative without the unpleasant scents commonly found in artificial logs.


Closing the Loop in the Coffee Industry:

Blazin' Joe aims to close the loop in the coffee industry, creating a truly circular system. By choosing their coffee-fueled fires, consumers actively participate in reducing spent coffee grounds and embracing a sustainable lifestyle.
