Sipa and the environment

Sustainability. Technologies and actions for recycling with a view to a circular economy.

SIPA's commitment to the environment is continuous, effective, measurable.
SIPA has always focused on a more reasoned consumption of PET, enabling its customers to produce lighter-weight containers, removing material where it is not necessary. All this without compromising any of the container's mechanical properties or aesthetic features.

SIPA specialists are experts in the sustainability loop, they plan to reduce resin consumption, energy and CO2 emissions in defense of the environment. In addition, they are among the pioneers of the "circular" approach: they design and rethink new technologies in order to give new life to post-consumer resources putting them back into the system. A forward-looking vision that combines environmental sustainability and economic development to deliver a better world to future generations.

XTREME Renew, the right system for the Circular Economy

With the introduction of XTREME Renew, SIPA stands as a leading company in compliance with the principles of Circular Economy. XTREME Renew is the world's first integrated system for the production of food contact preforms containing 100% r PET flakes. XTREME Renew was developed in collaboration with Erema, the Austrian company specializing in plastics recycling technologies.

The system is the synergistic combination of two already successful innovations – Erema's Vacurema and XTREME from SIPA. Compared with alternative systems for recycling old PET bottles back into new ones, it simplifies the process, uses less energy, reduces logistic and costs less to run.

This new technology offers significant advantages:

10% lighter bottles, with the advantage of using less raw material

15% reduction in production costs, compared to the traditional recycling process

20% reduction in logistics and transport costs

Significant energy savings: -30%, only 0.58 kWh / kg of PET

8O% reduction in CO emissions, compared to the use of virgin resin

100% sustainable: only recycled PET flakes

Simplification Vs traditional R-PET production

  • Bottle bales
  • Clean flakes
  • R-PET pelletizing recrystallization
  • Warehouse & Logistics
  • R-PET drying
  • Preform molding
  • Preforms
  • Bottle bales
  • Clean flakes
  • R-PET Preform molding
  • Preforms


As a means of identifying its commitment to safeguard the environment and in particular the climate, Sipa has engaged to carry out analysis and accounting on consumption of energy and raw materials, CO2 equivalent emissions and/or emission of other substances with an environmental impact, produced during the life cycle of the revolutionary XTREME RENEW application, within the context of the various categories of impact envisaged by the LCA method, in order to reduce them.

The project, which is being carried out with the co-operation of the Italian Ministry for the Environment, Land and Sea Protection, aims to identify procedures for the environmental management of products and/or processes, by keeping account of the environmental footprint generated by the life cycle of products (Product Environmental Footprint - PEF) and/or selected processes and related identification of measures to improve and optimise environmental actions (Organisation Environmental Footprint - OEF) for the impact categories that emerge from the study as most significant, assessing environmental performance using a scientific method that contemplates the impact of the life cycle (Life Cycle Assessment) according to UNI EN ISO series 14040 regulations.

The results of this study, which are given below, have been verified by DVN.GL (Management System Certification), acting as independent third-party assessment and verification body as required by current regulations.

LCA – Life Cycle Assessment

SIPA has carried out a life cycle assessment on its XTREME Renew process, so it can quantitatively compare its potential environmental impact in production of preforms from 100% recyclate (rPET) with a traditional process for producing PET preforms from virgin material (using a SIPA XFORM injection molding system). The results were independently verified.

Environmental footprint of plastic

Reduction of raw material

A more rational consumption of PET is the way to a greater environmental sustainability. For some time now, SIPA has been designing machines capable of producing lighter containers, shaving material where it is not needed. All this without compromising any mechanical or aesthetic property of the container, and without disadvantages for the customer

Reduction of consumption

SIPA was one of the first players to successfully process plastic bottles from plants and renewable sources. The company carries out a sustainable innovation program through continuous technical upgrades to minimize the environmental impact of the machines, increasing their efficiency and at the same time reducing energy, compressed air and water consumption.
