| Vestenenamer® | Vestenenamer®, a polyoctenamer, is blended with ground tyre rubber (GTR) from recycled tyres and adding this mixture to the bitumen and asphalts to be used in pavement. | The Vestenamer® process utilises a novel polymeric additive which not only aids processing but imparts enhanced physical properties to asphalt mixes and chip seal. Lowers the processing temperature and reduces stickiness. Mitigates odour issues associated with crumb rubber processing. Produces longer lasting and more rut-resistant roads than SBS modified bitumen. Conserves natural resources by replacing some of the bitumen with VESTENAMER® rubber powder when modifying asphalt. Recycling asphalt modified with Vestenamer® and crumb tyre rubber poses no technical nor ecological concerns. | Dosage is 4.5% addition rate, calculated on the rubber weight. |

Despite numerous cleanings, the productivity of the Reverse Osmosis plant would not recover from severe membrane fouling. The membrane autopsy revealed that the ferric hydroxide was seeding
silica polymerization and that even while the ferric hydroxide was removed, the silica scaling was continuing to grow.
The plant was experiencing weekly shutdowns for fiber clean up (~ 3 kg bags of matted slurry is cleaned per week). The shut downs were costly as they reduce plant availability for production.
