Using Plants to Make Plastics

Nuha Siddiqui & Kritika Tyagi on using the power of plants to edit the way we make and use single-use plastics.

By simply replacing the input, existing manufacturing lines can create single-use plastics for the new zero-waste economy.

“The world produces 400 million tons of plastic waste every year. That’s equivalent to the weight of the entire human population,” said Siddiqui. “We started erthos to drive this shift in the most natural, seamless way possible with plant-powered materials for our planet.”

Nuha Siddiqui, the co-founder of erthos, is transforming the plastic industry for the better. Bay Street Bull featured her on their 30×30 guide, which showcases Canadians redefining business, championing their communities, and cultivating new industries. The publication also bestowed her with the Belvedere Sustainability Award for erthos’ commitment to protecting the environment through innovative entrepreneurial endeavors. This all comes as erthos releases a new video explaining plastics’ negative environmental impact and erthos’ plastic waste crisis solutions.
