Naturally Advanced Technologies Inc. (“NAT” or the “Company”) is committed to unlocking the potential of renewable and environmentally sustainable biomass resources from flax, hemp and other bast fibers.

Naturally Advanced, through its wholly owned subsidiary CRAiLAR® Fiber Technologies Inc. and in collaboration with Canada’s National Research Council and Alberta Innovates – Technologies Futures, has developed proprietary technology to process bast fibers such as flax and hemp, cellulose pulp, and the resulting by-products. CRAiLAR® technology offers a cost-effective, environmentally sustainable processing solution expected to result in products with increased performance characteristics applicable to the textile, energy, composite materials, and auto, marine and aerospace industries.

Founded in 1998, Naturally Advanced adheres to a “triple bottom line” philosophy, respecting the human rights of employees, the environmental impact of the Company’s operations and fiscal responsibility to its shareholders.

Naturally Advanced Technologies’ strategy is to develop CRAiLAR® technology divisions that integrate proprietary biotechnology with current industry practice, and to commercialized those divisions with industry leading, strategic partners. Produced from bast fibers including hemp and flax, CRAiLAR® technologies are based on abundant, environmentally sustainable renewable resources. CRAiLAR® technologies provide economically attractive and performance oriented solutions to water and pesticide intensive feedstocks as well as petrochemical-based feedstocks, for industries such as textiles, pulp & paper, bioplastics, biofuels, medical and composite materials.

CRAiLAR® Fibers are the building blocks for the first truly sustainable yarn in the apparel industry. Fibers are processed through a patented enzymatic bath created in collaboration with the National Research Council of Canada. Prior to the bath, the fibers of up to a meter in length are cut to the desired staple length rivaling the very best long line cotton. These fibers then enter specialized processing equipment which turns the straw-like fibers into soft, white fibers similar to organic cotton.

The expected result is a yarn with the same warmth and feel of organic cotton, but with characteristics, such as tensile strength, that organic cotton simply can never achieve. As every step of the process can be certified organic, CRAiLAR® Fibers become the first truly sustainable yarn in the apparel industry.

CRAiLAR® Fibers division includes F-Series legacy technology.
