What sustainability means to us

Building Today to Protect Tomorrow

As an industry, we’ve already made huge strides in a range of fields, from education and awareness, to recycling materials, to redesigning processes to be more sustainable. Sustainability is so much more than innovation around products and systems. It’s an attitude and a frame of mind, informing our approach to every aspect of our business. Most importantly, it’s a journey, one where we’re always pushing to do better.

Taking action to cleaning the air

Emissions of air pollutants are too high across the world. According to WHO in 2016, 91% of the world population was living in places where air quality guidelines levels were not met.

BMI wanted to combat the problem, pioneering new roof membranes which could actually help to clean the air. Our Noxite membranes are one of our biggest innovations to date. Our team worked hard to ensure that it received its certification from the CSTB (the Scientific and Technical Centre for Building in France) and meet the highest countries' standards (Japanese one for example).

Noxite membranes use a photocatalytic coating, harnessing solar energy to react with harmful nitrogen oxides (NOx) in the air. Our membranes work as a catalyst, breaking down the NOx particles into nitrates – a harmless, more environmentally friendly by-product. The best thing is that the Noxite effect lasts the entire lifetime of the roof, with a very constant efficacity level.

No waste, heat and water reduction in BMI Iberia

Our Outeiro plant in Portugal, which has successfully reduced non-hazardous waste by more than 30%, thanks in part to the installation of a new heat exchanger. In the factory, clay tiles are dried after pressing, getting down to around 20% humidity.

Our new heat exchanger has transformed the process, reducing gas consumption by 10%: instead of using extra energy to generate heat used to dry the clay, the exchanger re-uses heat from other processes produced by the kiln.

In combination with other processes, the heat exchanger has helped the plant to significantly reduce their consumption. In the last year, BMI Iberia has also reduced waste water by 2%, thanks to the work of the Outeiro and São Francisco plants.
