The RT7000

Recycling Technologies introduces the RT7000, a chemical recycling machine capable of processing up to 7,000 tonnes of plastic waste per annum. The system is built on standard 6-metre ISO freight frames, allowing convenient installation at existing waste processing sites or as part of integrated plastic recycling facilities.

The main photograph above shows Recycling Technologies’ near commercial size Beta Plant at Swindon Borough Council’s recycling centre.

Feedstock types

The RT7000 is able to process the majority of residual mixed plastic waste including various types of material generally recognised as non-recyclable – i.e. films, packaging, laminates, black plastic and rigids.

Scanning and sorting system

The feedstock preparation module consists of a separation system that scans the material to ensure the levels of contamination are kept within acceptable limits. Undesired items, such as residual stones and glass, are rejected post scanning. The prepared material is then shredded and dried prior to chemical recycling.

Thermal cracking

The prepared feedstock is fed into the thermal cracker where the long carbon chains in plastics are cracked into shorter chains. The hot hydrocarbon vapour leaving the reactor enters the product separation module, where it is filtered and treated for impurities such as solid particulates and unwanted chemical compounds. The refined gas is condensed into Plaxx® while the non-condensables are recirculated back into the process.

Advanced control system

The process is continuously monitored through an advanced control system integrated into the RT7000. This allows the control of a number of variables such as temperature and flow, which ensures that quality of Plaxx produced is consistent across a wide variety of feedstock qualities.

EngD developing the design process & its environmental credentials.

The University of Surrey, having assisted in the design of the Fluidised Bed Thermal Cracker and Regenerator elements of the RT7000, is now engaged to model the lifecycle impact of the RT7000.

Suitable sites

A typical layout space would have a covered area for the feedstock preparation module with the core chemical unit located outside.

The figure below is only indicative of what a notional site would look like. In reality, each site will differ dependent on the nature of the plastic waste to be processed in the RT7000, the type of pre-treatment required by the plastic waste and the mechanical recycling equipment already available on site.
