P-Last is a biotechnology platform that converts non-recyclable plastics into high-value biomolecules and bioproducts.
Our conversion technology has the potential to redefine the boundaries of waste management, creating a new sustainable value chain and guiding society toward a more responsible and circular lifecycle for plastics.
P-Last contributes to 11 of the United Nations Sustainable Development Goals (SDGs):
Our technology is rooted in Brazil’s biodiversity and validated through advanced multi-analytical methods. We have developed a proprietary microbial platform capable of degrading different types of plastic and converting them into useful biomolecules.
We innovate by creating real pathways for waste that currently pollutes the planet to become regenerative inputs in a new production model.
By doing so, we transform one of the world’s greatest environmental challenges into an opportunity for innovation and circular economy, enabling an unprecedented sustainable value chain.
Julianna Peixoto, biologist and founder of P-Last, channels her passion for science toward building a more equitable society and improving quality of life through the preservation of natural ecosystems and the advancement of solutions with social impact.
Shortly after graduating in Biological Sciences from the University of Brasília (UnB), her commitment to environmental challenges was shaped by an experience in Chapada dos Veadeiros, in Brazil’s Cerrado biome. It was there, while observing plastic waste decomposing in the soil, that she identified both a pressing problem and a scientific opportunity — the potential for research that could transform our understanding of plastic biodegradation, one of the most critical environmental challenges of our time.
Since then, Julianna has embodied persistence and scientific dedication, transforming her vision into reality through an academic journey marked by years of research and discovery. Her work ultimately led to the development of the bacterial consortium that forms the core of the P-Last process.
With more than 14 years of experience in microbiology, molecular biology, and polymer physical chemistry, she has focused her research on developing innovative and practical solutions to the global plastic waste challenge. Her academic trajectory includes a Master’s and PhD from the University of Brasília, as well as postdoctoral research at The Hebrew University of Jerusalem (Israel) and at UnB.
“I first encountered P-Last while volunteering as a mentor for projects at Quintessa. I was immediately impressed to see Brazilian scientific talent being applied to address one of the planet’s most urgent challenges. I look forward to helping connect P-Last with investors who can support the industrial validation of this technology and help turn it into a truly effective solution to the global plastic waste problem.”
