Aquajet is a novel approach to recycle tires into small-enough, high-quality rubber particles for reuse in tire products.

Aquajet has developed a rubber recycling technology based on a proprietary process of milling whole tires with ultra high pressure (UHP) water jets, which is an alternative to shredding. With the lowest ecological impact, the fine rubber powder produced is unarguably the best rubber recyclate available. It has a very high surface-to-weight ratio, perfectly metal and textile free, displays no surface oxidation or thermal degradation, has a high degree of homogeneity, shows outstanding revulcanization characteristics, and is PAH compliant. The product has a wide range of applicability in the rubber industry, mainly in tire production.

IDEA

Poprietary process of milling whole tires with ultra high pressure (UHP) water jets

PRODUCTS

Ability for direct revulcanization, immediate applicability in manufacturing of new rubber products, substitutes NR /synthetic components

ECOLOGICAL

With lowest ecological impact, the rubber powder produced is arguably the best rubber recyclate available

Unique process for selective production of fine rubber powder from truck tires:

  • One-step process at ambient temperature
  • Clean technology – clean product
  • Closed-chain process, no harmful output
  • Beneficial product properties
  • No surface oxidation of particles
  • Chemically active surface morphology with nanostructures
  • Extra large specific surface

Aquajet is a novel approach to recycle tires into small-enough, high-quality rubber particles for reuse in tire products. The successful scaling up of the process shows potential for the future. Recycling and more specifically recycling of tires into quality products, as opposed to heat generation, will become more important in the years to come.

We recognize the quality of the work done to develop an optimized rubber powder and to enable its use as a raw material in rubber mixes, thus contributing to the preservation of the environment.

With sustainability on every tire company’s agenda, Aquajet’s technology is very much of its time. Having been steadily developed over several years, the renewed investment it received in 2015 proves that it is on the right track.

Through the Norway Grants and EEA Grants, Norway contributes to reducing social and economic disparities and to strengthening bilateral relations with the beneficiary countries in Europe. Norway cooperates closely with the EU through the Agreement on the European Economic Area (EEA). For the period 2009-14, Norway’s contribution is €1.7 billion. Grants are available for NGOs, research and academic institutions, and the public and private sectors in the 12 newest EU member states, Greece, Portugal and Spain. There is broad cooperation with Norwegian entities, and activities may be implemented until 2016. Key areas of support are environmental protection and climate change, research and scholarships, civil society, health and children, gender equality, justice and cultural heritage.
