CIRCULAR4.0 pilot action analysed a plant for pyro gasification of plastics, capable of processing 50 tonnes/year of organic waste: it can be considered as a 'hybrid plant fuelled by partially biodegradable waste', so it falls under the regime of renewable sources.

The gasification (sublimation process) carried out on organic matrices, i.e. carbon compounds, results in: a gas (syngas) that, once purified, could be assimilated to light hydrocarbons; a solid phase consisting of ash and charcoal; and a liquid phase consisting of washing water. In the pilot plant, the syngas feeds a cogenerator to produce electricity.

The plant is complementary and optimised for separate waste collection systems, but it is also suitable for operating with heterogeneous mixtures. The most evident advantages offered by this technology are the possibility of treating large quantities of waste that can no longer be recycled, obtaining energy, with practically no harmful emissions and solid residues that can be further exploited in other uses or in any case resulting in very small volumes. In this way, it is possible to alleviate the impact on landfills/incinerators or the waste transport system, producing energy and obtaining maximum value from waste with a view to a total circular economy.
