Kierrätysnesteet

Kierrätysnesteet, meaning "recycling liquids" in Finnish, refers to the collection and reprocessing of various liquid waste streams to recover valuable materials or render them harmless. This process is crucial for environmental protection and resource conservation, reducing the amount of waste sent to landfills or incinerators. Different types of liquids require specific recycling methods.

Common examples include used cooking oils, which can be transformed into biodiesel or animal feed. Antifreeze, a mixture containing ethylene glycol or propylene glycol, can be purified and reused, preventing the hazardous chemical from entering the environment. Solvents, often used in industrial processes, can be distilled and recovered for further application. Even wastewater, after treatment, can be recycled for non-potable uses such as irrigation or industrial cooling.

The collection of kierrätysnesteet typically involves specialized collection points or services that ensure safe handling and transport. Proper segregation at the source is often necessary to prevent contamination and maximize the efficiency of the recycling process. Technologies employed range from simple filtration and distillation to more complex chemical treatments depending on the nature of the liquid waste. The successful implementation of kierrätysnesteet programs contributes to a circular economy by minimizing waste and maximizing resource utilization.
