kumijätteitä

Kumijätteitä refers to waste materials composed primarily of rubber. This category encompasses a wide range of items, with spent tires being the most significant contributor. Other examples include rubber hoses, footwear components, industrial rubber products, and even certain types of packaging. The durability and slow decomposition rate of rubber make it a persistent environmental concern when not managed properly.

Historically, kumijätteitä were often disposed of in landfills, leading to the accumulation of large volumes and potential leaching of chemicals into the soil and groundwater. However, increasing environmental awareness and regulations have spurred the development of various management strategies. These strategies focus on reducing the generation of rubber waste, reusing rubber products where possible, and recycling or recovering value from discarded rubber.

Recycling processes for kumijätteitä often involve shredding tires into smaller pieces. These rubber crumbs can then be used in a variety of applications. For instance, they are incorporated into asphalt for road construction, providing improved durability and reduced noise. Rubber granules are also used in playground surfaces, sports fields, and as a component in molded rubber products. Furthermore, advancements in pyrolysis technology allow for the thermal decomposition of rubber to recover valuable materials such as oil, gas, and carbon black, which can then be used as raw materials in other industries. Despite these efforts, the sheer volume of rubber waste generated globally continues to present a challenge for sustainable management.
