Behind the Fibres: Banana Tree Waste Becomes Clothing

The problem with conventional textiles

The textile industry is among the most resource-intensive sectors in global manufacturing. Cotton is responsible for approximately 16% of worldwide insecticide use. Polyester is derived from petroleum and sheds microplastics with each wash. The fashion industry produces large volumes of unsold stock and post-consumer waste that mostly ends up in landfill or incineration.

Israel generates approximately 10 kilograms of textile waste per person per year. The second-hand market is growing — Yad 2, online platforms and municipal collection points are all expanding — but the upstream problem of what fibres are used to make new garments remains largely unaddressed in the Israeli market.

What banana fibre is

After a banana bunch is harvested, the plant's pseudo-stem — the column of layered sheaths that looks like a trunk — is cut down. It will never produce fruit again and is normally burned or left to decompose. This pseudo-stem contains long, strong fibres that can be extracted through a process called retting and mechanical separation.

The resulting fibre has a natural lustre similar to silk, a tensile strength comparable to jute and a breathability closer to linen. It is fully biodegradable, does not require additional pesticide or irrigation beyond what the banana crop already receives, and adds economic value to material that would otherwise be agricultural waste.

From plantation to fabric

Processing banana fibre into fabric involves extracting the fibres, drying them, spinning them into yarn and weaving or knitting the yarn into cloth. The process can be done at small scale by hand or at larger scale with modified textile equipment. Blending banana fibre with cotton or recycled polyester produces fabrics with improved drape and uniformity for apparel applications.

The processing is currently centred in South and Southeast Asia — India, the Philippines and Nepal — where banana cultivation is widespread and the technology has been developed at commercial scale. Israeli sustainable fashion brands importing from these supply chains are beginning to specify banana-fibre content as part of their sustainability positioning.

Applications and market development

Banana fibre is not limited to clothing. It is used for ropes, paper, handicrafts, tea bags and non-woven applications in packaging and insulation. The diversity of applications means that demand can be distributed across multiple market segments, reducing the risk of over-dependence on fashion cycles.

In Israel, the connection is primarily through import: sustainable fashion retailers and brands are the likely first adopters. The growing Israeli second-hand and sustainable apparel market creates the right conditions for banana-fibre products to find buyers willing to pay a modest premium for verified environmental credentials.

Why this matters beyond novelty

Banana fibre is not a silver bullet for the textile industry. It is one of several agricultural waste streams — including hemp, nettle, pineapple leaf and lotus — that can provide natural, lower-impact alternatives to cotton and synthetic fibres if processing technology and supply infrastructure are developed.

The principle matters more than the specific fibre: agricultural byproducts represent a category of raw material that currently has low economic value and high environmental cost. Converting them into commercial textile inputs creates incentives for farmers to manage agricultural residues rather than burn them, reduces raw material extraction for virgin fibre production, and diversifies the materials palette available to designers.

For Israeli consumers and businesses, the practical step is to ask about fibre content when purchasing textiles and to support brands that disclose and verify their material sourcing. Demand signals from purchasers — both retail and institutional — drive the investment in processing infrastructure that makes alternative fibres economically viable at scale.
