Tucson, AZ — HJ3 Composite Technologies, a company based in Tucson, Arizona, has been named a national finalist in the 2024 Cleantech Open Accelerator. This achievement follows their recent victory at the Rocky Mountain Region qualifier, marking another milestone in the company’s journey toward sustainable innovation. The Cleantech Open, now in its fifth year, is a global initiative that has supported over 727 cleantech startups, helped alumni secure more than $800 million in funding, and created thousands of green jobs since 2006.

As a national finalist, HJ3 will receive $20,000 in cash and in-kind support, and will compete against 24 other regional winners at the Cleantech National Global Forum on November 20th and 21st in San Jose, CA. The event offers a unique platform for finalists to connect with top investors and vie for substantial prizes, including up to $250,000 in funding.

Specializing in advanced composite systems, HJ3 focuses on providing durable, lightweight, and eco-friendly solutions for infrastructure reinforcement. With over 10,000 successful applications worldwide, the company’s patented carbon fiber technology offers exceptional strength, corrosion resistance, and environmental benefits. As aging infrastructure continues to pose a major challenge—costing an estimated $3.6 trillion globally and creating a $1 trillion funding gap in the U.S.—HJ3 helps clients reduce costs by up to 90% while extending the lifespan of structures by up to 30 years.

The construction industry generates massive amounts of waste and greenhouse gas emissions each year. In the U.S. alone, around 140 million tons of steel and concrete end up in landfills annually, contributing to significant CO2 emissions. HJ3's products offer a sustainable alternative, reducing both waste and environmental impact. Government agencies and Fortune 500 companies that adopt HJ3 solutions can significantly cut repair and replacement costs while promoting long-term sustainability.

The Cleantech Open is the world's largest cleantech accelerator, dedicated to supporting entrepreneurs who are developing innovative solutions for energy, environmental, and economic challenges. As a 501(c)(3) nonprofit, it provides the resources, expertise, and partnerships needed to transform bold ideas into successful global businesses. With over 1,500 volunteers and sponsors worldwide, the organization bridges the public and private sectors to drive growth in the cleantech industry.
