Recycling and repurposing byproducts and used material is essential to combating climate change and pursuing a sustainable future. Whether it's upcycling used batteries or simply purchasing secondhand fashion, renewable technology companies and resale businesses drive us toward an environmentally friendly lifestyle. Startup water purification company Glanris garnered investor support for its green water filtration media made from rice hulls, closing the latest Series A funding round for the business with $2 million.

“We set out to create sustainable solutions for water filtration and reuse that can immediately impact our global use of water,” said Bryan M. Eagle III, CEO of Glanris. “We also wanted to create a media that would lower the cost for companies wanting peak filtration performance and at the same time wanting to do something better for the planet. We have taken the world's largest agricultural waste product and converted it into a sustainable solution for solving the world’s water needs.”

Financing for the green technology startup business was supported by Riceland, Pittco Capital, Innova, and Sage. Glanris also announced that the startup company would be opening a 60,000 square foot facility to produce “the world’s first green, hybrid water filtration media” in Olive Branch, Mississippi. The new facility will allow the green technology business to produce three tons of filtration media per day.

Repurposing Waste Product for Clean Water

Founded in 2018 by Eagle and entrepreneurs Thomas Volinchak and L. Yu Lin, the Tennessee green technology startup company takes aim at unsustainable farming practices as well as water purification. Research studies estimate that roughly 100 million tons of rice husks are produced every year. It is not uncommon for rice farmers to burn or pay a disposal company for the removal of the byproduct; however, these practices frequently result in a large discharge of greenhouse gases into the atmosphere.

Instead, Glanris collects tons of hulls and transforms the waste into a media capable of purifying water. The green technology startup business uses an oxygen-free manufacturing process to produce its Glanris 901x media, which significantly cuts back on greenhouse emissions compared to traditional methods. Capable of filtering out both organic material and metal contaminants, the media produced by the startup company also possesses the ability to sequester carbon dioxide in the atmosphere.

Glanris claims that its green technology is cheaper, lighter, and more effective than conventional solutions, which often use environmentally harmful microplastics. The purifying media targets the industrial, municipal, and residential markets and requires no additional equipment to replace existing media.

A Green Solution in the Industry

Market research projects the global water and wastewater treatment market to reach $83 billion by 2023. Green technology companies and businesses like Glanris are tapping into a lucrative market, especially as concern over water scarcity grows in the scientific community. Access to clean water is essential, and startup companies in the industry stand to gain significant support from investors who are seeking a business that addresses important global humanitarian and environmental issues.
