The objective of this study is to provide an important building block of circular economy. This comprises the reuse of rubber from end-of-life tires for new tires, as well as saving our resources.

Pneumatic conveying is a transportation method for particulate materials commonly employed in industrial processes. Specifically, dilute phase pneumatic conveying, characterized by high gas velocities, low solid to air ratio, and low pressure drop, is utilized. In this report, three types of materials …

How can the stewards of our planet be rewarded and become an existential part of a brand-experience? Is our “Consumer mindset” actually able to always take our planet Earth’s viability in consideration while we’re consuming or buying products? Erwin van Woudenberg is a professor at HAS University of …

In the recent past, the use of resins in modern tread compounds has increased considerably, in order to further improve tire properties. Based on the experience with silica-silane filler system, which led to a different network structure and a significantly changed devulcanization behavior, the influence …

Tires are an important vehicle component, as car handling, safety and fuel economy depend for a major part on the tire composition and construction. As a consequence, tires are improved continuously. The most prominent improvement in the recent past was the use of a silica-silane filler system in passenger …

The local Dutch legislations (PGS-29) regarding the above-ground storage of flammable products have become stricter. This has led to the phasing out of Viking-Johnson couplings that are located inside of tank pits. These couplings are prone to leakage and they use rubber seals which are now prohibited …

The Amsterdam Sensor Lab is part of the Amsterdam University of Applied Sciences (AUAS) and its goal is to develop application specific sensor systems for applied research. In order to (anonymously) measure, for instance, traffic without influencing people’s behaviour, a pressure sensing sub-tile is …

Extrudate swell simulations and experiments have been performed with a viscoelastic tire rubber compound at high flow rates through a circular die. A 3-mode PTT model was fitted onto rheological data of the rubber. The PTT model covers the range of shear rates present in the simulation. Convergence of …

As a means to decrease the amount of waste tires and to re-use tire rubber for new tires, devulcanization of ground passenger car tires is a promising process. Being an established process for NR and EPDM, earlier work has shown that for ground passenger car tire rubber with a relatively high amount …

Bos Nieuwerkerk is een bedrijf dat schoorstenen maakt van aluminium en staal voor de industrie. Afhankelijk van de hoogte, diameter, wanddikte, etc. is een schoorsteen gevoelig voor dwarstrillingen ten opzichte van de windrichting. Deze trillingen zijn ongewenst omdat ze tot vermoeiingsverschijnselen …
