News: Tire Recycling & Pyrolysis

South Carolina state agencies started last week the waste management campaign fighting unsanctioned tire dumping in the Palmetto State. The move was made at the Scrap Tire Recycling Conference in Greenville. The authoritative bodies South Carolina Department of Health and Environmental Control, the Department of Natural Resources and waste managing organization PalmettoPride are behind the scrap tire project named "See It, Report It". The initiative appeals to locals and encourages them to anonymously notify special services via the Litter Buster Hotline whenever they spot illegal tire dumps. Once the call is received, the state agencies can take action aimed at waste tire reduction.

The tire waste management scheme, RepakELT launched in Ireland two years ago demonstrated effectiveness as the country managed to recycle 97 percent of scrap tires during the first year of the project, the Irish Minister for Communications, Climate Action and the Environment, Richard Bruton T.D. said in a recent report. The official emphasized that the scheme is being further worked on as it received 15 recommendations for improvement; stakeholders are expected to consider them. Burton also stressed that it was important to make tire manufacturers take responsibility for the environmental impact of tires.

A student from Mexico has created a self-repairing asphalt made out of recycled rubber from scrap tires and special additives, which help asphalt escape damage caused by rainwater. Moreover, rain would result in repairing roads as it would serve as a recovery agent, according to the innovation inventor, The Coahuila Autonomous University student Israel Antonio Briseño Carmona. The self-repairing pavement material created by Carmona mostly consists of end-of-life tires, thus, it is probably the first type of asphalt with recycled tire rubber that can, reportedly, handle damage caused by water, such as cracks and potholes, in the long term.

A number of tests and scientific research in Italy have shown that rubber obtained via tire recycling presents a more comfortable horse-riding experience and offers sustainably improved equestrian arena management. In addition, recycled rubber is more cost-efficient, can protect the horse’s joints and result in less dust in the air compared to conventional flooring with sand, according to the tests.

US-based Bridgestone announced recently that it has commenced producing tires containing carbon black (rCB) at its facility in Des Moines. In tire production, the company relies on carbon black supplies from its partner Delta-Energy, and uses its product, D-E Black, as the only source of the recycled material. Currently, Bridgestone has bought some 215 metric tons of Delta Energy’s rCB – this is the equivalent of over 60,000 scrap tires. By the end of next year, the company expects to apply around 6,800 of D-E Black, which would reduce over 20 million pounds of carbon emissions.

This event is considered one of the most important for the tire recycling sector in the region, according to the Latin American Conference official website, and is held as part of the larger XV Latin American Conference on Rubber Technology.

Eagle International – a manufacturer of tire recycling equipment specialized on debeading and cutting technologies for end-of-life tires – has launched a new site to help improve the user experience when researching and buying the appropriate equipment for their tire-recycling operations. The site offers up-to-date information and offerings that reflect the breadth of Eagle International’s product lines.

Tyre Stewardship Australia (TSA) that constantly searches applications for scrap tires now serves as a member of the International Rubber Study Group (IRSG) – an important informational body with connections to the rubber industry and international governmental authorities. IRSG currently comprises over 100 members from 36 countries. The group is involved in discussion of the matters influencing natural and synthetic rubbers, according to IRSG Secretary-General Salvatore Pinizzotto who welcomed TSA into his association.
