Kierrätyslisäaineet

Kierrätyslisäaineet, known in English as recycled additives, are materials derived from post-consumer or post-industrial waste streams that are reprocessed and incorporated into new products. These additives serve various functions, similar to virgin additives, but offer the advantage of reducing reliance on virgin resources and diverting waste from landfills.

The types of recycled additives are diverse, depending on the original waste material. For example, plastics collected through recycling processes can be ground down and used as a recycled plastic filler in new plastic products, such as construction materials or automotive parts. Similarly, certain mineral-based waste, like construction and demolition debris, can be processed into recycled aggregates for use in concrete or asphalt. Glass cullet is another common recycled additive, often used in road construction or as decorative elements.

The use of kierrätyslisäaineet contributes to a more circular economy by closing material loops. This practice can lead to reduced energy consumption and greenhouse gas emissions compared to the production of virgin materials. However, the quality and consistency of recycled additives can sometimes be a challenge, and their application may require specific processing techniques or formulations to ensure the performance of the final product meets desired standards. Research and development continue to improve the processing and application of these materials.
