THE TECHNOLOGY

A SCALABLE, INNOVATIVE PROCESS FOR WASTE PLASTIC

Turning waste plastic back into hydrocarbon feedstocks would take nature 200 million years. Mura’s ground-breaking HydroPRS™ advanced plastic recycling process does it in just 30 minutes.

THE HYDROPRS™ PROCESS

1

Waste Plastic Preparation

Background Image

The process begins by preparing the plastic. The feedstock is shredded and contaminants such as glass, grit, metals, and stones are removed.

2

Melt & Pressurisation

Background Image

The shredded plastic mix is then melted and pressurised.

3

Supercritical Steam

Background Image

The supercritical steam is mixed with the plastic.

4

Heat

The mix is further heated.

5

HydroPRS™ Reactor

Background Image

In the reactor, the plastics are broken down into liquid hydrocarbons and gas. This conversion takes as little as 30 minutes.

6

Depressurise

Following conversion, pressure is released. Energy recovered in this process is used to drive product separation.

7

Product Separation

Background Image

Products are separated into individual fractions for storage and onward sale to customers. Process gas is recovered and used in the process to generate supercritical steam. This saves energy and reduces the reliance on fossil fuels such as natural gas.

8

Product Upgrading (Process Bolt-On)

Mura and Engineering Partner KBR are currently developing upgrading integration into the existing HydroPRS™ design.

9

Product Storage

The products are stored before shipping to petrochemical customers, for use in the manufacture of new plastics and other materials.

A WIDER SCOPE FOR RECYCLING TARGET FEEDSTOCK

Mura’s Target feedstock includes the flexible, multi-layered materials that cannot be processed via traditional mechanical means, such as flexible films and multi-material rigids. These materials would instead be sent to incineration or landfill.

HydroPRS™ instead offers a viable recycling route, as part of a circular economy for plastic.

A WIDER SCOPE FOR RECYCLING TYPE & SOURCE

Target feedstocks for HydroPRS™ are polyolefins, including LDPE, HDPE and PP, alongside other plastic types 1 – 7 (PET, PS, ABS and polyamides).

Feedstocks are sourced from end-of-life, post-consumer plastics (films and rigids), MRF and agricultural residual material – materials which cannot be mechanically recycled.

A WIDER SCOPE FOR RECYCLING ADVANTAGES

1. Processes mixed plastic streams without segregation

2. Recycles post-consumer, contaminated materials

3. Complements existing mechanical recycling processes

4. Provides a solution to avoid costly packaging redesigns
