Plastic recycling process

Waste management systems and processing and separation technology is supporting the recovery and increasing recycling rates of plastic waste. Enva is at the forefront of these changes, leading in the development of plastic recycling processes and supporting a circular economy.

Once it arrives at our facility waste plastic is sorted, shredded, washed, separated before being extruded into specified ABS, PS, and PP polymers. Our state-of-art technology, that includes advanced electrostatic separation and optical sorting, produces one of the highest quality recycled plastic compounds in the UK. All our compounds are fully supported by comprehensive specifications and REACH data sheets, providing the peace of mind that they meet industry standards. 

Certain types of FMCG plastics are often more difficult to recycle back into polymers but, where possible, they are used in the production of an energy source for furnaces and kilns, namely SRF (Solid Recovered Fuel) and RDF (Refuse Derived Fuel).

Technical Data Sheets - Polystyrene (PS) and High Impact Polystyrene (HIPS)
Technical Data Sheets - Polypropylene (PP)
Technical Data Sheets - Acrylonitrile Butadiene Styrene (ABS)

Enva Plastics uses state-of-art separation technology to take what was previously waste destined for landfill and incineration from a co-mingled plastic waste into a high-end custom made plastic compound.

The separation steps comprise non ferrous and ferrous metal separation, size reduction, wet separation, dry separation including colour sorting and electrostatics and then custom blending and compounding.

Following years of Research and Development, the compound plastics separation process is unique to Enva, producing a finished product that holds a near-virgin polymer standard. These finished products undergo stringent impact, tensile and consistency testing within the Company’s own laboratory in Bourne ensuring that they conform to Enva’s high specifications.

This unique separation process, combined with Enva’s knowledge and experience gives rise to a quality, consistent recycled plastic product.

Plastic Products are tested for:

  • Impact: the industry-standard method of impact testing determines the impact resistance of materials
  • Melt-flow: measures the material’s melt to flow ratio under pressure ensuring Enva’s product are of a steady and even flow
  • Elongation: the plastic’s elasticity is tested, providing assurance that the product’s rupture and breaking point are consistently high
  • Density: this allows Enva to ascertain the density of the product, therefore lowering the probability of air bubbles being present when utilised for injection moulding.

Generally our compounds are supplied in either black, white or grey however it is possible to create via the use of additives virtually any colour to suit your brand requirements.
