Keräilytalous

Keräilytalous, also known as scavenging economy or byproduct utilization, refers to economic systems and practices that focus on extracting value from discarded materials, waste streams, or byproducts that would otherwise be considered refuse. This approach aims to minimize waste and maximize resource efficiency by repurposing or recycling materials into new products or energy. It encompasses a wide range of activities, from informal scavenging in urban areas to sophisticated industrial processes that recover valuable components from industrial waste.

The concept is closely linked to the principles of the circular economy, emphasizing the reuse, repair, remanufacturing, and recycling of materials. Keräilytalous can operate at various scales. On a small scale, individuals might collect discarded items for personal use or resale. On a larger scale, businesses may specialize in processing waste materials, such as plastics, metals, or electronic components, to extract raw materials for manufacturing. Industrial symbiosis is a prime example where the waste or byproduct of one industry becomes a valuable input for another.

This economic model offers several benefits, including reduced reliance on virgin resources, decreased environmental pollution, and the creation of new economic opportunities and jobs. However, it also presents challenges related to the collection, sorting, and processing of diverse waste streams, as well as ensuring the quality and safety of recovered materials. Public policy and technological advancements play a crucial role in fostering and expanding keräilytalous practices.
