Neste Opens World's Largest Liquefied Waste Plastic Recycling Facility

Neste Leads Global Plastic Recycling Innovation

Neste has launched the world’s largest facility for liquefied waste plastic. Also, this facility is located at the company’s Porvoo refinery. The main purpose of this plant is to convert liquefied waste plastic into high-quality raw material that can be used again in the plastics and chemicals industry.

Moreover, the facility has been developed with an investment of around 111 million euros. It is designed to process up to 150,000 tons of liquefied waste plastic every year. This makes it the largest facility of its kind in the world. Also, the production at the plant has already started, and it will gradually increase depending on market demand and regulatory conditions.

Moreover, the main idea behind this project is to handle plastic waste that is difficult to recycle through normal mechanical recycling methods. These waste types include mixed plastics, multi-layer packaging, and contaminated plastic waste. Such materials are usually sent to landfills or incinerated because they are hard to reuse. Furthermore, according to the company, this process is part of chemical recycling, which is considered a complementary method to traditional recycling systems. It allows more types of plastic waste to be recovered and reused instead of being wasted.

According to Towards Chemicals & Materials, the liquefied waste plastic market size accounted for USD 1.95 billion in 2025 and is predicted to increase from USD 2.3 billion in 2026 to approximately USD 10.3 billion by 2035, expanding at a CAGR of 18.11% from 2026 to 2035, due to the greater shift towards eco-friendly and cleaner energy sources.  

The company also highlights that the process is integrated with its existing refinery operations. Moreover, it uses a mass balance approach to track recycled raw materials in production. This helps ensure proper accounting of recycled content in final products.
