Greenville and Cryo Pur for Bio-LNG

Northern Ireland’s Greenville Energy and Paris-based Cryo Pur say they’ll build a pioneering bio-based liquefied natural gas plant at Tyrone, west of Belfast. The plant, to be online with Cryo Pur equipment next year, is to be “the first commercial unit in the world to produce liquefied biomethane from biogas on a small scale.”

Skytech is developing an innovative technological process for sorting industrial plastic waste in order to produce new regenerated plastic


The plastics industry uses several families of plastics to make objects with various characteristics: polyethylene, ABS, polystyrene, PVC, etc. At the end of their lifecycles, these objects are mixed, and therefore the plastics that constitute them are mixed as well. To date, due to the lack of a solution allowing their sorting, plastic waste is mainly incinerated or landfilled.

Recognizing the ecological urgency of recycling this waste, governments are significantly increasing national and international regulations: incentive policies, export bans, and increased taxes on landfills make the management of this waste more and more restrictive.

Since 2013, Skytech (former APR2) has positioned itself as a technological player in the recycling of plastic waste. By developing an innovative process for sorting a mixture of plastic waste to allow recycling on an industrial scale, the company is providing a concrete response to a major environmental challenge.

This automatic plastic sorting process, initiated in partnership with the CNRS, opens new paths to treating and valuing deposits previously considered waste.

Skytech is able to produce various types of high quality recycled plastics with similar oil-based plastic’ properties.

The process finally brings premium-quality new recycled materials to the manufacturers of the plastics industry. Skytech works continuously with researchers from the École Normale Supérieure Paris-Saclay to model this process, improve it and automate it.

Skytech chose to focus on the treatment of waste from WEEE (Waste from Electrical and Electronic Equipment) and ELV (End-of-Life Vehicles).

The company has recently been admitted to join Move’o, the competitivity pole to promote automotive industry reclycing ambitions.

The assets of Skytech:

  • Technical means and leading industrial processes;
  • An expert multidisciplinary team.
Cryo Pur

Cryo Pur manufactures and markets a biomethane purification and liquefaction system -2


Cryo Pur possesses an innovative technology that has allowed to establish:

  • An ultra-high performance system for the purification of biogas produced from waste which, thanks to a level of purity of more than 99% methane, enables its injection into the gas pipelines (GrDF in France) for a feed-in tariff. 
  • system for the liquefaction of methane produced from biogas (also called biomethane) which is unique in the world. Which makes it possible to divide its volume by 600 and therefore optimise transport. It could be used in particular as a biofuel.

Result of more than 15 years of research and development in partnership with the MINES ParisTech school of engineering, this globally patented technology was developed according to a new approach: cryogenics (purification of biogas at very low temperatures).

It allows, in particular, better refinement of biogas compared to existing technology, greater efficiency, with greater product purity without any loss of methane and without any greenhouse gas emissions.
