Innovation, quality improvement and sustainability determine the growth guidelines in Diseños NT. We currently put most of our efforts in making the most of all available resources and circular economy.

Our lines of research aim at optimising the life cycle of the raw materials we use, as well as promoting more efficient and environmentally-friendly processes.

Discover some of the R+D+i projects we are currently developing:


Non-woven fabric made of polypropylene of recycled origin

As a result of our commitment towards sustainability, and in cooperation with our supplier, DNT Non Woven Fabrics (which also belongs to Diseños NT Group) we have developed the ‘PE HB ECO’ Recycled Bond non-woven, made of up to 70% recycled material. We encourage the reuse and recycling of our products and we turn our wastes into new consumables for our production process. This way, we close the loop and increase circularity of materials. All that is achieved with no alterations of consistency and quality of the raw material and with no changes in the properties of the final product.

Our objective is to reduce the use of virgin resins and succeed in the production of non-wovens made of 100% recycled material.


Non woven ham cover with antibacterial control

The project “Active Ham: development of ham cover with antibacterial control made of plastic non woven material” has been co-financed by the European Regional Development Fund (ERDF), through the “Operational Programme Smart Growth 2014-2020” and the Ministry of Economy and Competitiveness, through the Spanish Centre for the Development of Industrial Technology (CDTI).

The objective of this innovative research project is the development of a new active packaging system which helps to preserve and prolong the optimum conditions of the Spanish cured ham during its consumption cycle, thanks to the incorporation of a series of antioxidant and/or antimicrobial agents in the packaging material (polypropylene non woven).
Ham’s shelf life after the first slicing is one of the main concerns of ham carvers. This research line has focussed in the study of the morphological design of the packaging material (polypropylene non woven) and the treatment applied to it. The results show a significant reduction of mould appearance on the surface of carved ham.

As a result of this study, the new material “Active Ham” provides added value to the final customer, as not only it is easier to handle and transport the ham from the store to the consumption place, but it also helps to extend its consumption cycle and maintain its organoleptic properties: colour, smell and taste.
