Experience

A RECIPNEU é uma PME, instalada em Sines, desde o ano 2000, que produz polímeros reciclados (granulados de borracha) a partir de pneus em fim de vida.

A RECIPNEU é certificada no Sistema de Gestão da Qualidade (NP EN ISO 9001:2008), Ambiente (NP EN ISO 14001:2004) e Higiene e Segurança (OHSAS 18001:2007).

A RECIPNEU possui uma capacidade instalada de aproximadamente 25 mil toneladas/ano de pneus usados, utilizando no seu processo a tecnologia criogénica. Esta tecnologia, rara na indústria recicladora de pneus europeia, proporciona granulados de borracha, que se diferenciam dos demais, obtidos por outras tecnologias, pelo elevado desempenho mecânico, químico e ambiental.

O granulado tem três grandes aplicações:

  • Superfícies desportivas – relva sintética e picadeiros;
  • Modificação de Betume com Borracha para aplicação em pavimentos rodoviários;
  • Matéria-prima para a indústria.

A empresa exporta, para todo o mundo, acima de 70% da produção total e mais de 90% dos produtos destinados ao enchimento dos campos de relva sintética.

A disputa de mercados tecnicamente sofisticados, eleva exponencialmente o padrão da competitividade, e o contexto onde se concebem, fabricam, embalam, armazenam e transportam os produtos, condiciona inexoravelmente o seu sucesso. Sines ou numa ótica mais inclusiva, o Litoral Alentejano, afigura-se como um território potenciador do desenvolvimento integrado e consequentemente da competitividade, onde emergem fatores, uns já consolidados e outros a afirmarem-se.

A Recipneu encara a participação ativa no desenvolvimento integrado da região como forma de potenciar a sustentabilidade própria e coletiva das organizações.

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.
