Finland is developing a new plastic processing technology.
VTT Technical Research Center of Finland successfully demonstrated the technology of chemical plastic processing, which promises to be an environmentally friendly alternative to incineration.
According to various estimates, approximately 40–60 percent of plastic waste in Finland is ultimately incinerated due to the technical limitations of mechanical processing. Plastic quality deteriorates with an increase in the number of recycling cycles, and it often happens that different types of plastic cannot be separated from each other.
“However, by chemical processing of plastics and their mixtures can be divided into individual types of raw materials, the resulting quality will be close to the quality of the corresponding raw materials,” said Anja Oasmaa, lead researcher at VTT Technical Research Center of Finland.
VTT demonstrated the feasibility of a new chemical processing technology during its two-year project, Business Finland WasteBusters, in which long polymer chains of plastics were divided into smaller ones as a result of pyrolysis or heating in the absence of oxygen (pyrolysis is the thermal decomposition of organic and many inorganic compounds) .). The final product is pyrolysis wax or oil, which can probably be processed in refineries in the usual way.
“Companies are interested in plastic waste to be transformed into chemicals other than plastics, which then will replace the raw fossil in a renewable manner,” said Oasmaa. “We want to develop this line of business with sustainable solutions in close cooperation with companies.”
The researchers also estimated that 10 pyrolysis plants in Finland could be profitable, and suggested connecting these plants to waste treatment plants. VTT is preparing further research related to this technology, for example, in the field of diesel fuel production, which can be used in flexible energy production (with flexible energy production, the use of multi-fuel plants allows for the constant selection of the most suitable fuel, including liquid, gaseous or renewable fuel, . per.) and for sea transport.
