2019 Agenda

The keynote will discuss the main strategic success factors or barriers to remove for using more sustainable materials. It will also illustrate Michelin’s ambition on that matter and potential technologies of interest to achieve this ambition.

 

This session will be hosted by the European Tyre & Rubber Manufacturers' Association

• Semperit Overview (Segments, application)
• Raw materials used at Semperit (share of Carbon Black, RcB) == target share of RcB (>2020)
• Our Requirements towards RcB (commercial, technical/quality, supply, packaging)
• Risks and Chances of RCB supply

 

How sustainability is practiced within the Hexpol Compounding Group

Insight into the negative effect that human activities have on the environment is rising rapidly and one can only conclude that Hexpol - like many other players - must raise the bar as regards action programmes that contribute to sustainable development.

A long-term strategy for issues that affect the environment, work environment, business ethics and social responsibility. We also see favourable opportunities to create business value through activities in these areas.

Recovered Carbon Black (rCB) rubber application has well known challenges, including surface area / particle size distribution limitations and in-rubber performance shift. The former limitations are resulting from recovering of the mix of the virgin Carbon Black (vCB) grades used in tires by a typical pyrolysis process. In-rubber performance shift (i.e. rCB demonstrates N3XX colloidal properties while exhibiting in-rubber performance typical for N7XX vCB grades) are usually attributed to several factors, including, but not limited to, presence of inorganic impurities in the rCB.

 

The patented G3C method converts existing in tires carbon black grades to the higher grades with higher surface area. This method is not just recovering, but also upgrades carbon black used in tires. The results of such upgrading are discussed in the presentation.

 

The G3C rCB purification represents the capability to remove a part or most of inorganic impurities from the rCB. The purification results and operating cost estimations for the future scaled up purification solutions are also discussed.

• Advantages of microwave pyrolysis (heat transfer, residence time, rCB)
• Different approaches to implementation (batch, continuous, new or retro-fit)

Recovered Carbon Blacks (rCB)s have long been proposed to be a N330 replacement. Data based on generally accepted characteristics from the carbon black industry - like surface area and structure level - are suggestive of high reinforcement properties of rCB. However, many of the currently used test methods from the carbon black industry do not seem to be suitable for categorizing rCBs. New test methods to better predict rCB behaviour in end applications will be required to provide the industry with the proper quality control tools so that batch-to-batch consistency can be guaranteed and relevant certificates of analysis provided. This presentation will walk through why test methods are important for rCBs and also provide an update on the latest relevant ASTM D36 activities focusing on rCB, rubber-derived liquids, and nomenclature highlights

The starting position is likely to be the same for industrial start-ups worldwide: there is a good idea for a technically, economically and ecologically sustainable solution to a problem (often even a proof of concept), but limited equity among the founders. Venture Capital and Business Angels find your solution "interesting", but they invest (usually) only if

•          the solution has already been implemented and patented,

•          the technology works well and

•          "customers are queuing in front of the door" (this also applies to many "funding agencies for EU subsidies").

After all, the Venture Capital ultimately determines the corporate strategy, which is often enough to grow as fast as possible and exit as quickly as possible (with the highest possible profit).

The problem is simply that you must prove something (in order to get money and to start), that you can only prove with this money!

How do you break out of this vicious circle? And how can you still retain control (as the founder)?
