Experiencia

RECIPNEU es una PYME, instalada en Sines, desde el año 2000, que produce polímeros reciclados (granulado de caucho) a partir de neumáticos al final de su vida útil.

RECIPNEU está certificada con las normas NP EN ISO 9001:2008 para el Sistema de Gestión de Calidad, NP EN ISO 14001:2004 para el Medioambiental y la OHSAS 18001:2007 para la Seguridad y Salud en el Trabajo.

RECIPNEU tiene una capacidad de producción de aproximadamente 25.000 toneladas/año de neumáticos usados, utilizando en su proceso la tecnología criogénica. Esta tecnología, rara en la industria de reciclaje de neumáticos europea, ofrece granulado de caucho, que se diferencia de los demás, obtenidos mediante otras tecnologías, por el alto rendimiento mecánico, químico y medioambiental.

El granulado tiene tres grandes aplicaciones:

  • Áreas deportivas – césped sintético y picaderos;
  • Modificación de betún con caucho para su aplicación en el recubrimiento de carreteras;
  • Materia prima para la industria.

La empresa exporta a todo el mundo más de un 70% de la producción total y más del 90% de los productos destinados a cubrir superficies como campos de césped sintético.

La disputa de mercados técnicamente sofisticados aumenta de manera exponencial el estándar de competitividad, y el entorno donde se crean, fabrican, empaquetan, almacenan y transportan los productos, condiciona inevitablemente su éxito. Sines o, desde una perspectiva más amplia, el Litoral Alentejano, se configura como un territorio impulsor del desarrollo integrado y, en consecuencia, de la competitividad, de donde emergen factores, unos ya consolidados y otros afirmándose.

Recipneu considera la participación activa en el desarrollo integrado de la región como siendo una forma de impulsar la sostenibilidad individual y colectiva de las organizaciones.

Acerca de Recipneu

Mission

Production of Cryogenic Rubber Powders and Granulates and the profitable valorization of all materials resulting from end of life tires recycling, through applications with market value and benefits perception.

Position

RECIPNEU assumes a leader position in cryogenic granulates quality and customer’s satisfaction.

This is the outcome of a Vision:

To provide unique products with intrinsic value both to the Customer and the Society, through highly advanced technological processes, which are all together economically viable, environmentally sustainable and ethically exemplar.

This vision is accomplished by a balanced strategy of short and long term targets, grounding in:

  • Research and development as tools for innovation;
  • Continuous training;
  • Preventive maintenance;
  • Market’s segmentation;
  • Positive discrimination of the cryogenic granulate;
  • Reasonable and emotional value to the Customer;
  • Company’s Valuation and sustainability.

RECIPNEU is aware of the importance that its products and activities confer either to Society or Environment. RECIPNEU’s code of conduct assumes Quality, Environment, Safety and Health policies as its tenets; the company understands such values as a requirement for productivity, competitiveness, and ethical sustained development.

Technology

RECIPNEU successfully implemented Cryogenic Technology for tire recycling – an innovation in Europe, both in terms of technology and products.

The industrial process takes place in three stages:

  1. Shredding raw material.
  2. Cryogenic processing.
  3. Bagging and storage

1. Shredding raw material

This stage consists of fragmenting light and heavy tires into small, homogeneously cut pieces – the “chips”.

2. Cryogenic processing

This process performs the complete and individualized separation of rubber, steel and textiles without noticeable waste or losses in material. This is a continuous, automatically controlled process which takes place under an inert nitrogen atmosphere.

2.1 Stages of the process

2.1.1 – Cryogenic cooling
The chips are dropped into a long cryogenic tunnel, and are cooled down by the action of liquid nitrogen, at around -196ºC, resulting in a cold exchange between the chips at room temperature and the liquid nitrogen. When the chips are cooled to a temperature of -80º C, the glass transition point (Tg) is reached for all the rubber polymers, so “rubber” behaves like glass.

2.1.2 – Cryogenic grinding
Under an inert and very cold atmosphere, the chips, “frozen” at -80ºC, are submitted to an extremely intense impact, of special hammer mills with very high impact energy, causing the instantaneous fragmentation of the rubber in small granules of various sizes.

2.1.3 – Separating the various materials, drying, sorting and purifying the end product.
The following steps lead to the completion of the process:

  • Magnetic separation of steel;
  • Drying the granulated rubber;
  • Sieving the rubber into different standard sizes;
  • Elimination of dust and steel contaminations

3. Bagging and storage

From the cryogenic line, the obtained granulates move on to various silos, where they are put into Big Bags of synthetic raffia fiber with approximately weight of 1,15 Ton, double nylon strapped over wooden pallet. The packaged product is then stored until delivery.
