Sooner or later, massive smokey burnouts will not merely burn rubber if tires from Continental are concerned. The worldwide producer is engaged on a plan to make tires fully out of sustainable, recycled supplies by 2050, however merely grinding up outdated tires to make new ones will not be sufficient. That is the place plastic bottles, dandelions, and rice husks are available in. Wait, what?
Pure rubber is sourced from particular timber within the type of latex, and that may proceed to be a key ingredient for producing tires sooner or later. Nonetheless, it will likely be supplemented by different plant-based sources akin to dandelions, that are additionally a supply of rubber. Silica can be utilized in tire manufacturing and performs a job in numerous elements of efficiency, from grip to rolling resistance. Typically sourced from quartz sand, plant-based oils could be a silica complement. Rice husks left over from rice manufacturing are an excellent supply of silica, with Continental saying the husks are a extra energy-efficient answer for manufacturing.
As for plastic bottles, Continental can use them to create a polyester yarn used for the tire casing. Relying on the bottle dimension, between 9 and 15 bottles could possibly be recycled for one tire. As with the Rice husks, Continental says utilizing the bottles is a extra energy-efficient different for capturing polyester wanted for manufacturing. This course of is already getting used on the firm for some tire casings. After which there’s the method of recycling outdated tires, separating rubber, metal, and cords in what Continental says is a “extremely subtle course of.”
In principle, the results of all these efforts will probably be tires created from 100-percent recycled or sustainably sourced supplies. In line with Continental, such supplies already account for between 15 and 20 % of contemporary tires.
“Continental is on the street towards changing into probably the most progressive producer within the tire trade by way of sustainability,” stated Continental’s Head of Sustainability Claus Petschick. “We purpose to make use of 100 % sustainable supplies in our tire merchandise by 2050 on the newest. Our progressive energy permits us to interrupt new and much more sustainable floor. This encompasses all the things from the origin and sourcing of our supplies by means of to the reuse and recycling of our tires.”
