The sustainability ‘movement’ in the plastics industry continues to advance, and materials and additives suppliers are among the leaders, largely through innovative industry partnerships, in this global endeavor, ranging from advances in mechanical recycling and chemicals to raw materials and biosourced materials. And, while single-use plastics have been front and center, this movement has grown far beyond that.

One example is the advancement of renewable raw materials in the polyolefin pipe markets and the Borealis Group is one of the most important players in this field with its partnerships with industry. According to John Webster, global commercial director for infrastructure at Borealis, “The use of certified renewable polymers is seen as a key lever in accelerating the transition from a linear to a circular plastics economy. It mitigates fossil resource depletion, helps everyone in the pipes and fittings value chain achieve their sustainability goals faster, and supports industry goals to become carbon neutral. Together with our pipe industry partners, we are committed to reinventing the plastics system for a more sustainable life. »

Check out these instant replacements for cross-linked PE and PP pipe made from Borealis’ Bornewables portfolio of polyolefins made from second-generation natural resources, such as waste from pulp production or residues of food processing oils. Based on a mass balance accounting process under the International Sustainability & Carbon Certification Plus (ISCC Plus) program, accreditation of these materials enables Borealis and its partners to prove and quantify the actual renewable content at every stage of manufacturing, from Bornewables material to final material. pipe. Both of these efforts are aligned with Borealis’ EverMinds activities and initiatives to advance the circularity of plastics through partnerships across the value chain.

▪ Cross-linked PE for HVAC

Bornewables PEX from Borealis was used by pipe specialist Upanor, Apple Valley, Minnesota to create PEX Pipe Blue, which would be the first portfolio of PEX pipes with renewable raw materials, accredited by the ISCC Plus program.

The new PEX Pipe Blue products offer an unprecedented carbon footprint reduction of up to 90% compared to conventional fossil-based PEX pipes. It also marks a major step forward in helping building and construction customers achieve their sustainability goals in plumbing, heating, ventilation, and air conditioning (HVAC) installations.

PP Pipe for Residential Plumbing, Heating and HVAC

Borealis has partnered with Italy’s NUPI (Houston-based NUPI North America) for high-performance rides based on Bornewables’ ISCC Plus certified renewable feedstock. Nupi Industrie Italiane (NUPI) is the first pipe supplier in Italy to use Bornewables in high performance random copolymer PP pipes for plumbing and heating systems. The company has selected Bornewables PP for the next generation of its Niron Beta PP-RCT (Polypropylene Random Crystal Structure Temperature) piping solutions for domestic plumbing, heating, and HVAC systems ( HVAC) designed to operate under stressful conditions and higher temperatures.

Bornewables PP would offer the same material performance as virgin PP. The partnership positions NUPI as a market leader, preparing for when legislation will require the use of renewable materials in pipe production, and establishes the company as the leading supplier of pipes in Italy by leveraging Bornewables PP Balanced Mass accredited under the ISCC Plus Regime.

Become Renewable with Advanced Material Technology PP-RCT, as defined by ASTM F2389 and EN ISO 15874, refers to a resistance chemistry of “polypropylene random copolymers with modified crystallinity and temperature”. As a direct replacement for fossil-based virgin PP, it eliminates the need for NUPI and end users to seek re-approval from water regulatory authorities.

Roberta Brusi, NUPI Group Quality Control Manager, said: “By adopting Borealis’ Bornewables PP for our new PP-RCT pipes, we are taking a big step forward in our efforts to reduce the carbon footprint of our products and stay ahead of tougher regulations where the use of renewable raw materials may soon become mandatory for plastic pipes. The material’s ISCC Plus certification also helps us document the renewable content of our PP-RCT formulation and pipes in a clearly traceable manner.
