A fundamental value for all companies in the IWIS Holding Group.

Ever since the IWIS Group began manufacturing, its various companies have always ensured their production facilities adopt technologies preventing pollution of the soil, air and water: IWIS's ongoing commitment to the community, to preserve the environment where we live and work.

IWIS HOLDING invests heavily in R&D in order to deliver quality products and further its technological innovation and environmentally friendly efforts.

The IWIS Group also uses recycled materials for some of its production processes, having specific plants at its disposal for recycling plastics.

Almost 50% of the energy used in the production processes comes from renewable sources: IWIS actually has three photovoltaic systems of its own, with rated outputs of 200 kWp, 150 kWp and 100 kWp. With a cogenerator producing another 800 kWP.

Environment and circular economy

Ever since TeMa was established, almost 30 years ago, we have taken our environmental responsibility very seriously.

In Europe, TeMa has set up its own collection and recycling plants (EcoTeMa in Russia and Replastica in Romania) to handle high-density polyethylene, and polypropylene, which come from the post-consumption of bottles, liquid containers and plastic bottle caps.

Circular economy, Plastic recycling


  • Sorting the materials - rejecting any that do not meet the strict preset standards in terms of quality and type.
  • Grinding and washing
  • Second grinding and washing cycle
  • Extrusion
  • Filtration - to ensure the resulting material is perfectly compatible for TeMa products.

The resulting salvaged material is then supplied to the Group's facilities and released onto the market.

As part of this process, all the washing water is treated so that it can be reused.

The amount of reused plastic plastic in TeMa products is determined in compliance with the standards and certifications in force in the respective countries, meeting the specifications of the customers' individual projects.

TeMa Technologies and Materials has decided to continue on its environmental sustainability journey.


We have subjected several product lines to an in-depth investigation to determine the consumption of resources and the impacts of the various stages in the product's lifecycle on the natural environment.

We have certified their performance through the inspection and certification body SGS and have been awarded EPD certification, unflagging and committed in our mission to reduce our environmental footprint.

Protecting the local hydrogeological system

TeMa's headquarters are located in an industrial area backing onto one of the regions recently recognized by UNESCO as a World Heritage Site. Having been here since its inception in 1993, TeMa has a strong sense of environmental responsibility and an unrelenting drive to innovate in this green direction. In environmental engineering applications, the TeMa Geo Solutions division ensures that every job is invisible to the eye and respects the land and the history of those that have shaped it.

Sustainable development

In order to address the issue of sustainable development, it is now crucial to have access to new materials when carrying out agricultural engineering projects. In the environmental engineering field, such projects as water drainage can be implemented without having to resort to large amounts of quarried aggregate that then has to be trucked in, instead turning to drainage geocomposites like TeMa Q-Drain, used in conjunction with finely slotted pipes for collecting and removing water.

These materials stand out for their: lightness, reduced overall dimensions (with minimal impact on the cost of the work in terms of transport, resulting in a substantial reduction in pollution), and fast installation.

System fully integrated with the soil

Another situation that is emblematic of the environmental advantages that come with using TeMa products is the reconstruction of slopes and banks that have been washed away and eroded, preventing or reducing slips: the use of biodegradable fibre matting such as Ecovernet made from natural fibres like jute, or Ecovermat made from natural fibres like straw and coconut, or biodegradable cellulose fibres. Installing products of this kind makes it possible to take immediate remedial action, even in situations where access for heavy machinery is limited.


These are just some examples of the potential offered by TeMa Geo to small or large environmental engineering projects whose focus is:

  • la feasibility, allowing for considerable cost reductions

  • sustainability of the works, reducing the use of natural resources

  • reduction of CO₂ emissions – carbon footprint
