Chemical recycling methods

 In the world of recycling, the ultimate goal is the creation of virgin quality materials from post-consumer waste. Unfortunately, this is often not possible through the mechanical recycling  because of contamination, composite materials and additives used in plastic.

Chemical recycling, also known as feedstock recycling, has the potential to overcome the issues of mixed and contaminated plastic waste to help create "as new" quality materials. It starts in the pyrolysis reactor where plastic is heated to around 500C in the absence of oxygen. This causes the plastic polymer to “crack” into smaller molecules until it becomes liquid and gas hydrocarbons, similar to those used to make plastics in the first place.

Unfortunately, the exact same contaminants that make mechanical recycling difficult also make pyrolysis oil difficult to process. The oil  is reactive and can quickly re-polymerise to form solid sticky gums that foul and block critical equipment. In addition, the presence of certain elements found in colours and additives cause poisoning of the catalysts used in the refining and petrochemical industry. Naturally, this makes feedstock recycling viable in only very limited circumstances.

Our Solutions

At Refiniti, we developed technology to improve the characteristics  of pyrolysis oil in a refining process that enables it to be used as a high value petrochemical feedstocks. Our patented solutions provide significant economic benefits for waste polymer pyrolysis operations. 

The advantages and features of our technology & solution are:

1. Mild processing conditions to minimise energy requirements .
2. Scalability from waste management through to refining operations
3. Compatible with batch and continuous pyrolysis processes 
4. Suitable for both plastic and waste tyre oil.
 

 

 

 

 

 

 

Pyrolysis in UK refiniti

Refiniti has developed efficient refining methods to remove catalyst poisons and significantly reduce the reactivity of pyrolysis oil to make it more suitable as a feedstock for the chemical industry.

By achieving this, we have created an amazing opportunity to increase the recycling of various plastics and rubber materials.
