LUBBOCK, Texas – Sustainable products are the focus these days, and industries must do a better job in research and communication with customers.

 

The 79th plenary meeting of the International Cotton Advisory Committee dedicated a good amount of time in discussing this important topic.

 

A recent discussion with Dr. Kater Hake, vice president for Agricultural and Environmental research at Cary, N.C.-based Cotton Incorporated, provided good insights on sustainability.

To a question on “What is Sustainable Cotton,” Dr. Hake aptly answered, “any sustainable product has to meet the needs of human globally without sacrificing the wants of the future generation.”

 

The cotton sector from fiber to fashion supply chain is working hard toward this goal.   

 

Cotton is tolerant to drought and salts and is grown in rainfall deficient regions such as West Texas and Africa. Growers are adopting many sustainable practices such as no or reduce till, and reduced fertilizer inputs while aligning sustainability with profitability, said Dr. Hake.

 

I have articulated sustainability as a System with three Es: 1) Environmental; 2) Energy; and 3) Economical in an article, ”Sustainability in the industry: where do we go next?

 

The cotton crop provides jobs for many farmers in countries such as India, where a farmer may own one hectare or less. This helps with social sustainability, giving opportunities for farmers in developing regions of the world.

 

While there is no doubt that sustainable products come with cost, over a period and lifecycle of the products, the cost gets absorbed. As the cotton prices are riding above 1 dollar per pound now, with inflation high in four decades in the United States, how such increased cost would be received by consumers is interesting to observe.

 

One solution to tackle this price issue with natural fibers is to increase global production to reduce the price, according to Cairo-based Prof. Mohamed Negm, chairman of International Cotton Researchers’ Association. Perhaps the global cotton production should increase to 35 million metric tons/year from the current level of about 25 million tons/year, added Prof. Negm.

 

While technical textiles sector is dominated by synthetics, there is growing interest and a push to go plastic free.

 

“Sustainability can mean different things to different people, so there are a wide variety of sustainability claims made to get on this bandwagon, using terms like ‘natural’ and ‘free from’ and adding small percentages cotton, hemp, wood-based fibers and others. There is a push for a ‘plastic-free’ wipes substrate by 2025, and a lot of material science activity to achieve this,” said Dave Rousse, president of Cary, N.C.-based INDA, Association of the Nonwoven Fabrics Industry.

 

The climate change issue has heightened the need to go sustainable in all sectors. The immediate need is to engage in dialogue with all stakeholders, particularly with consumers by improved communication strategy.

 

More importantly, immediate research investments need to be made by both private and public entities. Benefits to such investments are huge, said Dr. Hake, by highlighting few developments that have happened in the cotton sector like increased fiber strength, which has led to reduction in the weight of cotton garments and the amount of fiber needed to make durable products.

 

Plastic pollution is small water systems, and large marine environments are attracting due attention, which drives the sustainable development of biodegradable products.
