Marco Arezio: Professional Profile of an Expert in Plastic Recycling and the Circular EconomyFounder of rMIX, international consultant and author of over 10 technical manuals on recycled polymers Code: 11726. Author: rMIX Editorial Staff · Profile updated: March 2026 Marco Arezio is the founder and owner of rMIX – The Platform of Recycling, the Italian reference portal for the circular economy and the recycling of plastics and more, active since 2020 with headquarters in Bergamo. With over 35 years of professional experience in the materials, plastics, and construction sectors, and more than 20 years of direct experience in the production and international trade of post-consumer and post-industrial recycled polymers, Arezio today represents one of the most comprehensive and verifiable profiles in the Italian technical dissemination landscape on the circular economy. His professional output is structured along three parallel and complementary axes: a corporate career in management roles at leading companies in the plastics and construction sectors, international business consultancy in the recycled polymer sector, and editorial production —with over 10 technical manuals published on Amazon that cover, polymer by polymer, a large part of the mechanical and chemical recycling supply chain. A career built on recycled polymers: from 1988 to today Marco Arezio's professional career began in 1987 and, over the course of thirty years, spanned all the main segments of the cultural heritage restoration sector, from building materials to technical plastics, up to specializing in post-consumer and post-industrial recycling. His first contact with the transformation of materials took place at SICEM Srl (1987–1992), where he held the role of Technical Sales Manager for the consolidation services of monumental buildings, developing a structural expertise in building materials that would accompany his entire subsequent career, with prestigious works such as those carried out in the Sistine Chapel on Michelangelo's Last Judgement. This was followed by seven years as Sales Area Manager at Magnetti Building SpA (Grigolin Group), with responsibility for the sales network in the brick, prefabricated floor, concrete paving and block sectors. The leap to general management came in 1999, when he joined Gutta Werke SpA as General Manager for almost eleven years. In this role, Arezio managed the production and marketing of plastic construction products and roof waterproofing systems using recycled and non-recycled materials—an experience that consolidated his technical expertise in polymers used in construction and the international building materials markets. His direct transition into the world of post-consumer and post-industrial recycling took place in 2010, when he joined BREPLAST Spa as International Sales & Marketing Director, a role he held for nearly seven years. During this time, he established and managed the international sales network for the sale of recycled polymers in HDPE, LDPE, LLDPE, MDPE, PP, and PP/PE in pellet, flake, and densified form, developing business relationships with industrial buyers and sales networks in Europe, Asia, the Americas, and Africa. He also served as an active technical advisor on the use of recycled polymers as a replacement for virgin raw materials. Between 2016 and 2017 he held the same management role at MONTELLO SPA , one of the leading Italian companies in the recovery and recycling of post-consumer plastic materials. Since 2018, he has been working as an independent Senior Sales and Communications Consultant in the plastics sector, assisting companies with international market strategy, web marketing, and specialized technical communications. Since 2020, he has founded and managed the recycling portal rMIX , where he has published thousands of technical articles on recycling technologies, European regulations (ESPR, REP, Green Deal), recycled polymers, recycling materials and techniques, the environment, management, and international markets for secondary raw materials. Technical skills: polymers, technologies and markets Marco Arezio's decades of experience have translated into a verifiable and documented technical expertise spanning the entire polymer recycling supply chain. Post-consumer and post-industrial recycled polymers: its direct expertise covers the main recycled thermoplastics, including HDPE, LDPE, LLDPE, PP, PP/PE, PET, ABS, TPO, PBT, PS, PC, PC/ABS, and PVC, in pellet, flake, and densified forms. This expertise is built on over twenty years of international technical and commercial transactions, not theoretical expertise. Recycling technologies: continuously follows the evolution of mechanical, molecular and chemical recycling technologies — from depolymerization to pyrolysis — with constant updates documented in the technical articles published on rMIX. Plastics for construction and waterproofing: Gutta Werke's long-standing experience guarantees specific expertise in plastic products for construction, waterproofing systems, and polymer sheets for construction applications—a niche segment with few specialists in the Italian landscape. European regulations: ESPR (Ecodesign for Sustainable Products Regulation), Extended Producer Responsibility (REP), the European Green Deal, and the recycled content directives are topics systematically covered on rMIX with a technical-practical approach aimed at industry professionals. International markets: the sales network developed over years of activity covers Europe, Asia, Africa, and Latin America, with specific expertise in secondary raw materials markets and in the management of international industrial buyers. Amazon publications: the most comprehensive Italian-language technical body of literature on plastic recycling. The element that more than any other qualifies Marco Arezio as a leading technical author in the Italian panorama is his systematic editorial production on Amazon: over 10 technical books that address the recycling supply chain polymer by polymer, with an approach that integrates materials chemistry, industrial processes, quality control, markets, and regulations.

How to Use Ion Mobility Gas Chromatography in Recycled PlasticsHow to Use Ion Mobility Gas Chromatography in Recycled PlasticsCode: 9959. How to Use Ion Mobility Gas Chromatography in Recycled Plastics to Trace Process and Raw Material Odors.As we have extensively described in other articles, the world of recycled plastics, especially those that come from separate collection, defined by post-consumption, they have the problem of managing the odorous component that is established inside the recycled raw material. Odors that come from the heterogeneous composition of the plastic in the collection phase, from the fermentation processes of the organic residues incorporated in the plastics to be recycled, from the washing water not managed in correct manner, from the degradation, during the extrusion phase of the granules, of plastics mixed with the main ones and of chemical substances absorbed by the containers during their packaging function, such as surfactants for example. The production of recycled granules done without the chemical control of the incoming material, the control of the water and the extruded materials for sale, is like driving in the night with the lights off. The commitment of company resources to purchase the raw material to be recycled, processing costs, logistics and sales costs, could be put at risk by '' impossibility of producing a raw material in recycled plastic that meets the expectations of the final customer in terms of odors. The analytical control of odors in the input materials allows us to select suppliers, divide them by categories and draw up production recipes that take into account the odor footprint of the products inbound. The same analytical control will be used to check the correct production process and formulation of recipes, not only from a technical aesthetic point of view, but also from an odoriferous one, to giving the final customer an extra quality that is increasingly sought after by the market. And, finally, the commercial can calmly propose a granule that has a license for the smell, not questionable or questionable through other noses, especially from those who are employees in the purchase of the granule produced, but through a certainty provided by a chemical analysis of the odorous components present in the product. How does this laboratory technology work? Dr. Rossini explains it to us:The technology underlying the instrumentation we are talking about is the GC IMS (Gas Chromatography with ionic mobility). This technology applies to volatile organic substances originating from a static headspace generated under standardized conditions. A chromatographic gas column allows the preliminary fractionation of the volatile substances introduced before entering the heart of the instrument. The heart of the instrument is made up of a 9.8 cm metal tube inside which an electric field of 5,000 Volts is created; the volatile substances from the chromatographic column are ionized by a source containing tritium (a low intensity radioactive substance). The ionization process takes place at ambient pressure and is based on the interaction between the water present in traces in the nitrogen gas which acts as a "carrier": The chemical-physical process of ionization is such that volatile organic substances such as alcohols, aldehydes, ketones, carboxylic acids, aromatic compounds, amines, thiols, halogenated compounds , etc, are electrically charged and therefore made detectable by the Faraday plate placed at the end of the flight tube. The aforementioned substances are those responsible for the "odors" that are perceived by the human sense of smell: the "extreme sensitivity" of the detection system that reaches the level parts per billion (ppb). The electronic nose is therefore made up of a GC IMS detector, coupled with an autosampler that has the task of heating the 20 ml glass bottles in which they are located the substances (liquid or solid) that develop the volatile substances. The way to perform the analyzes is extremely simple, since there is no preparation of the product to be analyzed. In the sector of recycled or recycled plastics it is really easy to prepare the samples and get the tests. The analytical result consists of a three-dimensional diagram like a geographical map of the mountains: the "geographical map" indicates the elution time from the chromatographic column, the flight time and signal strength of each individual volatile organic substance. This instrumentation therefore allows you to compare in an "objective" way the recycled plastics that emit volatile organic substances perceptible to the smell.Origin: ItalyCategory: Machines and molds - electronic nose - odor control - laboratory test machinesIf you are subscribed to rMIX contact the company, if you are not, subscribe by choosing the contract you prefer.
