Hemp, or industrial hemp, is a botanical class of Cannabis sativa cultivars grown specifically for industrial or medicinal use. It can be used to make a wide range of products. Along with bamboo, hemp is among the fastest growing plants on Earth. It was also one of the first plants to be spun into usable fiber 50,000 years ago. It can be refined into a variety of commercial items, including paper, rope, textiles, clothing, biodegradable plastics, paint, insulation, biofuel, food, and animal feed.

The hemp fibre is encased in thermoplastic to make a reinforcing bar.
Corrosion, in environments with high salt concentration, concrete structures are given a lifetime of 40 to 50 years.
The hemp rebar is made through a pultrusion process in which the fibres are pulled together with thermoplastics into a heated die and melted to form a solid bar.
The first step is to make the hemp into a rope containing a blend of natural and plastic fibres – the exact "recipe" for which the RPI team is still finessing.
Coils of this rope are then fed into a machine created especially for the process. This device, a CNC machine about the size of a small car, sits on-site and forges the rebar on demand, reading from digital files to bend and cut the product to the stipulated shape.
