What are the challenges facing the growth of the nonwoven industry in emerging markets?

Both the average per capita income and distribution of this among a given population play a role in the speed of adoption of nonwoven-based products. In addition, cultural factors (such as the public attitude towards single use products, where waste management infrastructure is not optimal) mean that there is no single answer for all emerging countries.

Can you cite some examples of latest technological innovations taking place in the nonwoven industry? How accepting are companies of these technological innovations?

Downgauging, which refers to reducing the amount of material in a product while still maintaining or even improving the properties and performance of the material or end product, has long been a major focus for the nonwoven industry, more simply referred to as "grammage reduction". This does not seem to have reached its absolute limits yet in all end uses, and continues to be the subject of a lot of research and development efforts, just like "hybridation" or composite technologies, whereby properties of webs made of and/or bonded by different means are combined. Other than that, there are obviously a number of individual and often confidential proprietary developments, some of which remain private at this stage, but some of which I hope to discover with the delegates in Edana's future conferences and symposia. An innovation is by definition a commercially successful development anywhere in the supply chain, from the extraction of raw materials to the delivery and end of life of a product. It is therefore often not just companies that have to develop or embrace technological developments, but also their customers or consumers, who have the power to make these successful or not, and therefore truly innovative or not. This means that marketing efforts must work together with any technical developments to deliver a successful product innovation to market. In this respect, I believe that the nonwoven supply chain is very progressive, and has a great capacity to create successful technology developments throughout its length. The catalysts created by inventors are of course still important for breakthrough innovation, but the general attitude of a value chain (such as the nonwoven and related industries) is to embrace and maximise the potential of incremental developments which, we believe, is the most important factor.

Nonwovens' fastest growing application is in filtration? Do you agree?

There is little doubt that non-mineral or non-metallic filter media are one of the most consistently fast growing nonwoven end uses on a worldwide basis thanks to global concerns and efforts to improve pollution control, indoor air quality, energy efficiency and water purification.

Are the applications of nonwoven in the filtration industry as compared to the personal care and hygiene industry higher or expected to be higher in the near future?

The trends applicable to filtration versus the personal care and hygiene application areas are different, and therefore difficult to compare or rate against each other. Industrialised countries show a relative saturation of baby and feminine care markets, whereas adult incontinence products are the growing markets there, whilst emerging countries are - on average - at a lower level of market penetration of baby and feminine care products. For filtration, the needs of national markets can vary widely based on their current level of personal or national infrastructure and the requirements of local population.

Can you brief us about the new conferences and symposia for nonwovens scheduled for 2015?

The Edana Outreach Programme, designed to spread our core message and in particular our leading product stewardship approach, enables us to move throughout the world with great efficiency, especially in helping to improve the value chain's understanding of the benefits in promoting sustainable products. Here are the planned events so far for next year: 2015 3-5 March, 2015 Outlook Plus Latin America Sao Paolo, Brazil 17-18 March, 2015 Filtrex Hong Kong, Asia 3-4 June 2015 International Nonwoven Symposium + AGM Prague, Czech Republic 23-25 September, 2015 Outlook, Athens, Greece 5-6 November, 2015 Nonwoven Innovation Academy Leeds, United Kingdom
