Custom Bio-Based Solutions

Inspire and enable innovators around the world to emulate nature’s time-tested forms, processes, and systems as we solve this century’s greatest challenges.

Utilizing natural fiber Human Plant Solutions has created a patent pending alternative to often caustic, high cost, conventional ultra light composites for prosthetic and device manufacturing. In 2017, we developed the first hemp fiber definitive device prototype for a high activity, below knee amputee. The patient has been wearing the original prototype device since then, competing in competitive events including a 70.3 Ironman race and most recently this year’s virtual Boston Marathon.

Our Products


HPS GREEN RESINS are seamlessly interchangeable with their traditional petro-based counterparts, and require no special processing. They retain the same or better physical characteristics, including mechanical properties, and chemical and UV resistance.

RENEWABLE CONTENT HPS offers several EcoTek resins that use up to 30% bio-derived, renewable resources. RECYCLED CONTENT Up to 45% of our resin content can be post-industrial recycled material.


Natural fibers possess a high strength to weight ratio, non-corrosive nature, high fracture toughness, renewability, and sustainability.

About Us

Our vision includes improving the lives of customers with affordable, sustainable prosthetic solutions. Human Plant Solutions is educating skilled patient care providers and technicians, creating a community of innovation around sustainable products. By utilizing natural materials we are less dependent on carbon, petroleum based products and synthetic polymers. Finishing laminated fiberglass and carbon fiber causes extreme skin and respiratory irritation.  Conventional materials are often very high cost and extremely caustic to work with for fabricators and device manufacturers. Working in agricultural production, manufacturing and fabrication of hemp-based materials, our goal is to improve lives and to move into other markets that can and will develop products proudly labeled “Made in the USA”.
