As an innovative supplier of specialty polyesters solutions, Selenis is dedicated to providing solutions to the challenges our planet faces. Our long history in the polymers industry feeds our know-how and experience to achieve sustainability in both the solutions we offer to our customers as well as in our own operations.
Selenis’ goal is to provide sustainable solutions that support the advancement of a circular economy and considerably reduce plastic waste. We are devoted to playing our role in society’s collective response to the challenges we face, by jointly working across the value chain to create tangible solutions.
Selenis focuses on developing products that meet sustainable standards in recyclability, eco- resource efficiency and eco-friendly compositions (alternatives to conventional materials such as BPA and styrene). For this reason, Selenis has focused on a circular economy for PET since our foundation. It’s in our DNA.
Selenis Eco Resins incorporate up to 50%
post-consumer recycled content
At Selenis we believe in science. To us, investments in R&D are a priority and our technology focuses on delivering solutions that close the loop.
PET has an established, accessible end-of-life option – recycling. To Selenis, recycling PET is a lot more than keeping PET bottles out of landfills. To Selenis, recycling PET is about creating a valuable manufacturing feedstock that can be reprocessed and used as a raw material in the production of specialty copolyesters. This is why launched our ECO Series, supplying a sustainable version of all our product portfolio that include up to 50% post-consumer recycled content. Selenis ECO resins enable brand owners to:
Incorporating post-consumer recycled content into the production of new raw materials greatly reduces carbon emissions and greenhouse gas, as well as requiring less energy overall to manufacture the new product.
At Selenis we bring positive end-of-life solutions for PET materials that might otherwise be discarded in landfills. Through our recycling process, polyester-based products are reduced to their polymer building blocks – called monomers. They are then reintroduced to the value chain as recycled polyester raw materials, delivering a true circular solution.
Removal of solid contaminants during transfer of the monomer between the esterfier and the polymer autoclave with higher efficiency than mechanical recycling due to low melt viscosity of the monomer.
During the polycondensation process, that takes place in the polymer autoclave. In the course of the melt phase, the batch is submitted to a high vacuum level, below 1 mbar, for a significant period of time.
Final products have better overall properties when compared to mechanical recycling and no thermal history.
The Selenis process recovers monomers through molecular recycling. Glycolysis is used to break-up PET waste and reduce it to its polymer building blocks—called monomers. Next, they are reintroduced to the value chain as recycled polyester raw materials.
What is unique about Selenis breaking-through technology is that we combine the recycled PET with virgin raw material at specific dosages, according to production throughput and desired percentage of recycled content, resulting in the production of new polyesters with high levels of PCR.
Through the mechanical recycling process of the recycling unit of our sister-company Evertis, we convert waste material into “new” raw material, without changing the basic structure. At Selenis we then convert the PET flake into new polymers through molecular recycling.
At times Evertis has recovered a volume of
bottle bales equivalent to 90% of PET.
At Selenis we convert these bottles into new polymers
At our Industrial Site in Portugal, Selenis, Evertis (sister-company) and the Evertis recycling unit, are vertically integrated. As an integrated recycler, specialty polyester and multilayer barrier film producer, we have created synergies that translate into a lower carbon footprint thanks to the reduction of raw materials transportation costs.
Selenis has been certified by PRS for our efforts to accelerate a circular economy in our supply chain.
The PRS Green Label emphasizes our joint responsibility and recognizes our company’s efforts in actively contributing to this long standing truly circular model.
Through our partnership with PRS, Selenis provides sustainably sourced pallets that are either FSC or PEFC certified. At Selenis, we control the re-use and shared use of CP-type pallets, both internally and with our clients, by tracking and recollecting pallets for their reuse.
At Selenis we directly contribute to a circular economy as well as reducing our environmental footprint:

Associations are increasingly becoming a vital element for creating solutions that close the loop. Selenis believes in close engagement with organisations who share the same commitment to create initiatives for a circular economy. Either directly or through our sister-company Evertis, our group is a member of the following Foundations and Associations:
Selenis is a member of the Association of Plastic Recyclers (APR). Through this alliance we enhance plastic recycling by improving quality and increasing supply through technical resources, testing programs, design solutions, corporate training, regulatory leadership and educational programs.
PIEP is an initiative of the plastics and molds sector that collaborates with the University of Minho, through the Department of Polymer Engineering (DEP-UM) and IAPMEI, of which Selenis is a member. The main objectives of PIEP, amongst others, are:
Strengthen the competitiveness of the plastics and molds industry, through the development of proprietary technologies and the conception of innovative products.
Promote a culture and an effective practice of R&D practices.
Show the national endogenous capacity to respond, in useful time, to specific innovation challenges.
Through our sister company Evertis, we participate in various Working Groups with the objective of listening to a variety of perspectives, sharing experience and knowledge, brainstorming for generation of ideas and achieving a supportive collaboration. Selenis specifically contributes to the working groups that focus on:
Recycling PET thermoforms - Tray to Tray
PET monomer recycling special industry group
Working Group on opaque and functional bottles
Evertis is part of a communication taskforce that is working on a future communications campaign with the main objective that PET remains the material of choice for packaging. Additionally, we have financially contributed to the campaign, together with several other members of Petcore Europe.
Through our sister company Evertis, our group is a member of NAPCOR and actively collaborates with peers on key projects and tackle significant issues affecting PET packaging throughout its life cycle. Through our membership we reenforce our commitment to the responsibility of our environmental impact and recycling of our products.
Evertis has contributed towards NAPCOR’s Positively PET campaign, designed to:
Educate consumers on PET attributes and how to recycle PET
Promote environmental benefits of PET
Counteract the negative imagery PET is receiving
Through our sister company Evertis, we participate in several Working Groups that promote and support activities that contribute to a circular economy. Additionally, we influence EPRs to promote a tray-to-tray recycling stream.
Founded by the Ellen MacArthur Foundation, the Plastics Pact is a network of global initiatives that gather all strategic stakeholders, at national or regional level, to implement solutions towards a circular economy for plastics. The pacts are based on the idea of a common vision for plastics that will accelerate the transition to a closed loop economy for plastics, referred to as a New Plastics Economy.
Through our sister company Evertis, our group is a founding member of both the Portuguese and the US Plastics Pact. Each initiative is led by a local organisation and unites governments, businesses, and citizens behind the common vision with a concrete set of ambitious local targets.
Through our sister company Evertis, our Group is a founding member of the European Plastic Pact, which aims to accelerate the shift towards the reuse and recycling of single-use plastic products and packaging.
Our group has contributed to the creation of the EPP Roadmap, aligned with existing European initiatives such as the UN Global Partnership on Marine Litter, the Basel Convention, the national Plastics Pacts, the global commitment from Ellen MacArthur foundation and the European Commission’s Circular Plastic Alliance.
Additionally, our group participates in several working groups in order to:
COOPERATE across the value chain on a European scale to boost the development of smarter techniques and approaches, and cement an innovative community;
HARMONIZE guidelines, standards and national supporting frameworks. Countries will take on current legal barriers, creating a level playing field and building scale;
CONNECT to share their best practices and lessons learned across Europe in meetings, annual progress reports and on the website, in order to accelerate the shift to circularity by default.
Through our sister company Evertis, our Group is a signatory member of the Circular Plastics Alliance, which, supported by the European Commission, endorses the ambitious target that by 2025 at least 10 million tons of recycled plastics should find their way into products and packaging in Europe each year.
