Kierrätyspolttoaineen

Kierrätyspolttoaineen, often translated as recycled fuel or waste-derived fuel, refers to fuels produced from various waste materials. This process aims to recover the energy content of waste that would otherwise be landfilled or incinerated without energy recovery. The primary goal is to reduce the volume of waste destined for disposal and to create a source of energy, often contributing to the circular economy.

The raw materials for kierrätyspolttoaineen can include a wide range of non-recyclable or difficult-to-recycle waste streams. These can encompass plastics, textiles, paper and cardboard contaminated with food or other substances, wood waste, and certain types of industrial byproducts. The suitability of a waste material depends on its calorific value and the presence of contaminants that could hinder combustion or release harmful emissions.

The production process typically involves sorting and preparing the waste. This may include shredding, drying, and sometimes removing inert materials like glass and metal. The prepared waste is then processed into a fuel form, which can vary. Some kierrätyspolttoaineen is produced as a fluff or powder, while others are pelletized or extruded into more uniform shapes.

Kierrätyspolttoaineen is primarily used as a substitute for fossil fuels in industrial combustion processes, such as cement kilns and power plants. Its use can help reduce reliance on virgin fossil fuels, thereby lowering greenhouse gas emissions associated with energy production. However, the environmental impact of kierrätyspolttoaineen also depends on the specific waste materials used, the efficiency of the production process, and the emission control technologies employed during combustion. Careful management is crucial to ensure that the energy recovery process does not create other environmental problems.
