**4. Conclusions**

The quality and quantity of end-of-life plastics are continuously improved while the amount of recycled material is always too low. Several firms such as AmSty and Agylix [28], ReVital Polymers, Pyrowave, and INEOS Styrolution [29], BASF, Quantafuel, and REMONDIS [30], Neste [31], and so on are involved in recycling plastic materials using thermochemical processes [1] using, mainly, classic heating method. This review shows the MAP process developed by Techwave as an industrial novelty proposed for the friendly and economical disposal of waste/contaminated plastics. In this way, valuable products, useful as a source of secondary raw material, close the cycle of a circular economy because plastic waste is converted in a feedstock for the production of new plastics.

MAP is a very interesting way to dispose of end life plastics because it does not produce waste from chemical recycling of plastics but three classes of products: a char, an oil, and a gas, available as fuel or the source of new materials for the synthesis of new products. The process is self-sustainable from an energetic point of view rendering the process economically sustainable. The Techwave proposal offers an industrial plant designed to obtain secondary raw materials from plastic wastes, thus closing the cycle for a circular economy and giving a strong advantage in terms of environmental protection and expansion of the recycled material market in a green and sustainable way.

Finally, the plant was realized as planned, so it is possible to introduce in two standard containers for its shipping. Furthermore, a plant of this dimension may be installed in a municipal collecting and selecting center of waste plastic where it may be employed to pyrolyze the mixed plastic present, avoiding the transport of this waste for disposal. The plant may be useful also for a large hospital to dispose of the waste/contaminated plastic present, taking into account that the pyrolysis products do not contain biological contamination because they are destroyed in the course of

the process as reported in the literature [24, 25] while the products formed may be sold on the market. The dimension of the plant lets its installation on one small ship where the waste plastic materials present in the sea may be collected and immediately disposed. The products formed may be employed to produce the energy required for all operations, while the excess may be sold on the market.
