We are an ever-evolving company. We pursue goals which, at the beginning of the new millennium, would have seemed unrealistic. We are aware of the fact that innovation is not enough to keep pace with market demands: we need to take responsibility for the choices we make, which affect all stakeholders and the territory. Sustainability has now become a tangible, widely endorsed concept, and change is not only necessary and unavoidable, but is being demanded by many. In 2015, the UN 2030 Agenda charted a course for global sustainable development, and more and more consumers are rewarding the efforts made by companies to implement policies aimed at achieving these goals.

At Caleffi, we have always made strategic choices by making investments and striving to ensure that our processes and practices have a positive impact on society and the territory. For us, sustainability means ensuring environmental, social and economic well-being for future generations by combining thermal comfort and water and energy savings, which are guaranteed by our products.



Over the years, we have implemented a number of sustainable activities. One of the first things we did was to upgrade our plants in order to make them eco-friendly. In the mechanical processing department, we replaced old fan equipment with new generation equipment. We decided to use LED lighting in several departments and installed condensing boilers in all of them. The modernisation work carried out also involved the roofing of Caleffi 1 (in Fontaneto): 36 % of the 47,000-square metre area now has a modern reflective surface. The goal is to complete the project over the next few years so as to achieve not only significant energy savings, but also an effective improvement in working conditions.
No waste and the reduction of polluting materials are also a priority for Caleffi. As a manufacturer of heating and plumbing components and systems, our company processes huge amounts of brass every year.
We comply with regulations requiring the use of low-lead or lead-free alloys for certain countries. In order to keep ahead of the times, meet market demands for increasingly greener products and comply with future legal requirements, we use low lead alloy components on many of our products, which are distributed worldwide.

Moreover, we strive to find solutions aimed at recovering 100 % of waste from mechanical processing. We install innovative systems on machinery in our production plants so that we can also recover brass scraps and oil and emulsion residue, which play a crucial role in certain processes. We don’t take anything for granted, and the fact that we are able do this in large numbers has a remarkable impact on production: our oil recovery system allows us to recover more than 50 % of the oil we use in a year (90,000 litres) and the TTS system to sift, sort and recover 100 % of the swarf produced (more than 6,500,000 kilos).



A total of 1,000,000 kilos of high-performance plastics are processed at our plants every year. We definitively got rid of scraps and milled material more than 10 years ago. Today, by constantly innovating our production plants, we are able to reuse and recycle up to 98.5 %, collecting anything that can be cleaned and reused, re-milled and fed back into the machine, or sorting anything that can be recycled by external companies.
Our major recovery project also includes plastic packaging: for some lines and for specific customers, we no longer use shrink wrapping and have made changes to our packaging system. As a result, we are able to use 6 tonnes less cellophane per year.

Over the last two years, the company has been slowly getting rid of paper and cardboard. We have introduced a new waste sorting system by strategically placing 21 vertical presses to compact huge amounts of cardboard (as well as incoming plastic packaging) into compact bales, which are fully recycled.

From recycling cardboards, we prevent at least 300 tonnes of CO2 being released into the atmosphere. Equivalent to planting 2,000 new trees.



We are working on several projects in the field of ecological sustainability. In addition, we are looking at solutions that will allows us to colour technopolymers in an eco-friendly way and to recover up to 100 % of post-processing waste. In short, we never stop.



We have a shared sustainability vision. We strive to build a virtuous circle involving our suppliers, personnel and customers. We know all our suppliers well and have established relationships of trust with many of them, which have been maintained over the years since those who work with us must uphold the same ethical, social and quality standards that we have set ourselves. In the last few years, we have opted to maintain a short supply chain: in fact, today, 98.7 % of the raw materials used to manufacture Caleffi products are sourced from Europe, and 85 % exclusively from Italy. This conscious choice allows us to directly and continuously monitor our suppliers, significantly reduce CO2 emissions, and make sure that we do not source our materials from countries where human labour is not valued, respected and developed.


Caleffi Green is a project strongly supported by our President Marco Caleffi, who has always been actively involved in promoting sustainable values. This project was conceived with the aim of raising awareness of the role that we can all play and how we can contribute to sustainable development. How? By implementing tangible, green actions within our company, such as switching to plastic free packaging, replacing disposable plastic with compostable and biodegradable materials, eliminating other polluting materials, and introducing systems and equipment that have a lower environmental impact.
We no longer use plastic bottles and all members of staff have their own water flasks. The 125,000 cups we use every year are all made of compostable cellulose from controlled, regularly planted forests.

(reference year 2019)

  • Every year, over 70 tonnes of paper and cardboard are recovered from our production, office and logistics areas.
  • Integrated cardboard bale system - also canteen packs, which actually accounts for 100 %.
  • 17 tonnes of recovered polyethylene - 100 % of incoming packaging and unpacking waste from the production department
  • Packaging for certain lines/Specific customers no longer want plastic - no more shrink-wrapping.
  • The packaging system has undergone changes - 50 kg
  • Pad printing: we are switching to lasering where possible
  • During shipment polyethylene reduced by 60 %: from 720 kg to 288 kg
  • Plastic bottles used on the premises 100 % eliminated 
  • Recovered plastic scrap: 98.5 % (reuse or external processors)
  • Waste plastic scrap: 1.5 %
  • With regard to the use of Ecobrass: the percentage of Ecobrass used has increased from the initial 1 % in 2015 to around
    11 % today (2019).
  • In 2019, the photovoltaic panels installed on the CUBOROSSO produced 23,000 kWh of electricity.
  • An area of approximately 17,000 m2 was covered with reflective insulation, therefore about 36 % of the total covered area (47,000 m2 ). Our goal is to cover all of it.
  • By improving its management, we have cut down on the amount of water used for air conditioning by about 33 %.
  • Methane gas consumption: in 2019, we consumed about 18 % less methane gas than in 2018
