About us

SERMAG is an Italian company founded in 2003 that produces and sells recycled polyolefins (LDPE, HDPE, PP) specializing in the research and development of recycled compounds.

SERMAG has created an industrial network with Italian companies with which it has shared not only the production phase but has also jointly developed an analysis and research activity, the latter in collaboration with the university.

SERMAG has managed to establish itself with authority in the field of recycled plastic materials thanks to the great experience in the field accumulated over the years and the scrupulous attention dedicated to every phase of product processing, from design to construction.

SERMAG can produce polyolefin blends with recycled plastic according to specific customer needs, combining performance and sustainability.

The products in polypropylene or low and high density polyethylene have recycled percentages up to 100% and are applicable to the packaging, construction, compounding, molding and extrusion sectors.

All products are guaranteed and tested by the SERMAG “Laboratorio Materie Plastiche Circolari”.


It is a Secondary Raw Material in high density polyethylene certified 100% PCR Patent Pending,

perfectly colourable, suitable for blowing cans and containers

or for filming up to a thickness of 12 µm, miscible with LDPE or LLDPE

SERMAG's brands

SERMAG has created nine commercial brands to divide its products and to help customers find the best solution.

The recycled materials in PP, LDPE and HDPE have technical specifications and properties that have nothing to envy to the corresponding virgin raw materials, thus constituting an excellent alternative, more sustainable and in accordance with the most recent European regulations.

Analysis and quality check

The modern laboratory, shared with the Sermag network, and equipped with the most modern instruments available on the market (IR and XRF spectrophotometer, differential scanning calorimeter (DSC), gas chromatograph), allows SERMAG to carry out continuous monitoring on each lot of product , in order to ensure precise compliance with the pre-established production standards.

The constant checks that are carried out on all phases of the production process and the advanced technologies for the treatment of materials, allow the products of all brands to reach and satisfy the high quality standards required by the customers and technical-regulatory ones, required by the laws and regulations in force.

The certificates of analysis performed on each lot treated, allow customers to have a complete and detailed overview of the physical and mechanical properties and a guarantee on the quality of the materials.

All the materials are also tested and guaranteed to comply with the European REACH and RoHS regulations.

Research and development

SERMAG is one of the leaders in Italy in the development, production and sale of polymers and elastomers composed of secondary raw materials and by-products. The continuous development of new blends of polymers and elastomers, allows to always have a solution available for every type of application and request from the customer.

SERMAG compounds can also be manufactured according to specifications dictated by the customer, thus creating customized mixtures to meet the most particular needs and obtaining a completely tailor-made final product.

This feature makes SERMAG a unique company of its kind, capable, thanks to its corporate network, of transforming and adapting recycled materials to a wide range of applications from construction, to packaging, to the automotive sector.


In order to guarantee total transparency to customers, SERMAG has obtained authoritative certifications for its products and processes.

So far SERMAG has requested and obtained 15 certifications from CSI IMQ Group, regarding the traceability of materials, the compliance with the reference UNI 10667 standards, the origin of the regenerated materials (PIR or PCR) and the percentage of recycled content in each product.

In 2021 SERMAG obtained the KIWA Covenant, European certification that concerns the Secondary Raw Materials produced by EuCertPlast certified plants, from which SERMAG procures, which declares the origin and the minimum content of 99% of recycled plastic.

Sermag obtained two new certifications for its products in 2022, “Plastica Seconda Vita” and “Remade In Italy“.

For SERMAG it is a source of pride to be able to certify its products and therefore to be able to sell them guaranteeing the highest standards of quality and safety.

Sustainability according to SERMAG

The circular economy has been in Sermag’s DNA since the beginning of its activities, it has always focused on the eco-sustainability of its products and processes.

SERMAG almost exclusively uses recycled polymers, intended as secondary raw materials, and by-products, trying to minimize the use of virgin plastics. The ennobling use of regenerated materials and by-products allows less exploitation of non-renewable resources and allows for a significant reduction in carbon dioxide emissions during the production cycle.

The commitment to respect a green and sustainable company policy is also supported by SERMAG customers who consciously choose regenerated products, preferring them to virgin raw materials.

TPE-O, the flagship of SERMAG

In patent matters and considering a view to circular economy, SERMAG constantly studies and experiments mixed-compound with a high content of recycled polymer to improve their technical and performance characteristics and make them an alternative to virgin raw material.

A tangible example of this work is the compound TPE-O, patented at European level, a mixture of polyolefins and atactic copolymer polypropylene specially designed for the modification of bitumens for the production of bituminous membranes.

TPE-O is available in the form of granules and according to the user’s needs, it is produced in various grades by modifying the characteristic parameters such as density, Melt Flow Rate, viscosity, “ring and ball” and cold flexibility.

This compound manages to combine environmental sustainability, being the product with a percentage of more than 60% of recycled material, performance and flexibility of use thanks to the great study carried out in the design phase and the feedback provided by customers who use it successfully.

PCR, not waste but resource

Sermag’s commitment in the field of the circular economy is also manifested in the distribution of secondary raw materials with 100% PCR waste origin (post consumer recycling), that is, according to the ISO 14021 standard, plastic waste produced by the end user, people, families, activities and businesses, normally destined for landfill.

Sermag has developed compounds with secondary raw materials PCR based focusing on polypropylene and high and low density polyethylene. Riplastene™ brand is entirely dedicated to these products, which are aimed in particular at the sectors of compounding for blow molding and molding.

The careful processing of the waste, which is also traced in every movement and treatment, allows to obtain a secondary raw material that is 100% recycled and that can be reintroduced directly into the market, with mechanical properties and physico-chemical characteristics of all respect if compared with equivalent virgin materials.

Sermag is investing heavily in these eco-sustainable products, which really are able to give new life to waste and greatly reduce the environmental impact due to the production of virgin plastic.
