The RT7000

The RT7000

Recycling Technologies’ solution to the problem of End-of-Life Plastic is the RT7000, a chemical recycling plant capable of processing up to 7000 tonnes of plastic waste per annum. This machine produces a valuable hydrocarbon named Plaxx®. The system is as 6-metre ISO freight frame modules, allowing convenient installation at existing waste processing sites or as part of integrated plastic recycling facilities.

Feedstock types

The RT7000 is able to process all categories of plastic (1 – 7) including various types of material generally recognised as non-recyclable plastic waste – i.e. films, packaging, pots, rigids and engineered plastics.

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

This feedstock is then 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

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 Reactor and combustor elements of the RT7000, is now engaged to model the lifecycle impact of the RT7000.
