Jungle rubber: achieving the triple p business opportunity, people, planet and profit

Jungle rubber: achieving the triple p business opportunity, people, planet and profit   

The global loss of biodiversity has become one of the major environmental challenges of the 21st century. For one, biodiversity is a fundamental component of long-term business survival. According to the United Nations Food and Agriculture Organization, 40% of the world's economy is based directly and indirectly on the use of biological resources. Safeguarding biodiversity therefore is integral to sustainable development, competitiveness, economic growth and employment, hence important for business. This is especially true, when natural resources are used, such as natural rubber. As one of the largest rubber producers in the world, almost 2 / 3 of the rubber in Indonesia is produced on small farms (<5 ha). In Sumatra and Kalimantan, a total of almost 3 million hectares of rubber is cultivated by small-scale rubber producers in mixed cropping systems, also called jungle rubber. Up to 70% of the biodiversity usually found in natural forests, is present in these jungle rubber systems. In addition, jungle rubber is CO2 friendly. The amount of commercial energy required for harvesting, processing and transporting natural rubber is only a fraction compared to synthetic rubber (about 10%). Findings from our feasibility study, funded through the SBIR facility for biodiversity (AgentschapNL), showed that jungle rubber can provide new markets as a social and ecologically sound, profitable natural product, waiting to enter a growing market of consumers looking for socially-just and environmentally-friendly products.

Chances and Threats for Natural Rubber for Use in Low Rolling Resistance Tyres

Chances and Threats for Natural Rubber for Use in Low Rolling Resistance Tyres   

Since the upcoming of the ECO tyres, silica is on an upwards trend in passenger car tyre tread compounding. The silica-silane filler system allows for reducing the rolling resistance of tyres compared to carbon black filled material, which results in fuel savings of the car. Elastomers applied for this technology are primarily synthetic rubbers: solution - styrene butadiene rubber (sSBR) and butadiene rubber (BR). In contrast to this, truck tyres are mainly made from natural rubber (NR); being the most ecological polymer of all as it is a natural, green, sustainable product. However, this causes a problem as NR does not work with the silica/coupling agent systems, and possibilities to change the polymer are limited. Making NR compatible with silica remains a challenge, but also offers a tremendous potential for a reduction of energy consumption for transport. The main difference between NR and synthetic polymers is the presence of a considerable amount of non-rubber constituents in NR. Proteins and the coupling agent have an antagonistic effect in silica reinforcement of natural rubber. The utilization of modified NR and deproteinized NR (DPNR) is a possibility to enhance the compatibility between silica and NR, as well as to minimize protein adsorption on the silica surfaces, respectively. This enables the rubber compounder to use this natural polymer for truck tyre treads, making the DPNR/silica systems a green material in terms of composition as well as application. The presentation will give an overview of a series of studies into the problems encountered with NR/silica systems, and the feasibility of implementing silica technology in natural rubber for low rolling resistance tyres.

The energy life cycle approach to green tyre technology

The energy life cycle approach to green tyre technology   

Meer ecologisch verantwoorde producten spelen een steeds belangrijkere rol in de hedendaagse maatschappij. Deze trend wordt binnen de bandentechnologie verder aangemoedigd/afgedwongen door de Europese labelling van autobanden die vanaf 2012 verplicht is op het gebied van rolweerstand, geluid (en wetgrip). Grote bandenleveranciers waaronder Apollo Vredestein spelen dan ook meer en meer in op de trend om banden ecologisch vriendelijker te maken. Als je een milieuvriendelijke band wilt ontwikkelen kun je dat op verschillende manieren benaderen, bijvoorbeeld vanuit de gebruikte grondstoffen, het design, of gebruik van andere productie-omstandigheden. Binnen Apollo Vredestein worden meer eco-vriendelijke autobanden ontwikkeld door de totale levenscyclus van de band te bepalen en te analyseren. In deze voordracht wordt deze strategie verder uitgelegd, worden voorbeelden gegeven van nieuwe receptuurontwikkelingen en aandacht besteed hoe we de idee
