The great challenges that humanity has to face and the actual problems are climate change, pollution and waste created by individuals who live and work leaving residues of their own activity. From the 70s, the progressive awareness of environmental issues has given rise to a wide debate on the future of the planet. If it is true that we can intervene on pollution with a greater use of existing technologies and materials and with a change in our life habits, it cannot also be said that the great problem of waste can be easily solved with the sole use of incinerators.

This debate has involved international organizations, opinion movements, governments and scholars and led to the concept of sustainable development: "Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs" (Gro Harlem Brundtland, 1987).

Sustainable development combines the needs of economic growth with that of human and social development, quality of life and the protection of the planet from a long-term perspective of well-being.

The environmental, economic and social aspects of sustainable development integrate and mutually support each other in order to build a more equal, healthy and harmonious society for all.

For this reason, sustainability is increasingly becoming an integral and key part of our lives, our choices and our consumption, as a strategic element for a new model of development and unlike what it might seem, sustainability is not an anti- growth idea, but rather a model that pursues development in such a way that resources are respected and used wisely.

The three characteristics of sustainability

The concept of sustainability consists of three distinctive elements:
1. economy
2. society
3. environment

It is therefore possible to talk of sustainability only when there is a balance among these three elements; to protect the environment, promote widespread well-being and preserve economic growth and development.

The main goals of the sustainable model

The goal that this model wants to pursue is to preserve the resources of the planet on which we live and on which we depend.
In particular, the main categories of reference are:
· Sustainable energy: to abandon fossil sources and switch to the use of renewable energy sources
· Sustainability and equality: to allow everyone to have the same opportunities and the same minimum level of well-being
· Sustainable communities: to create communities that choose a lifestyle which is respectful of ecosystem resources
· Sustainable cities: to design new cities and redesign existing cities based on environmental and social criteria
· Sustainable consumption: to educate individuals to conscious and informed consumption
· Sustainable trade and industries: to make the use of resources more efficient


With a view to environmental and economic sustainability, Expansion Electronic undertakes, in the production of its electrostatic filters, to guarantee high filtration efficiencies, minimum electricity consumption, to use recyclable (100% aluminum) and renewable materials; the filters need only a simple annual wash and not a continuous replacement.

This allows us to preserve the environment by adopting a clear and precise choice of not having continuous waste, replacement costs, disposal and being able to count on a product with a long life, equal to or greater than that of the ventilation systems themselves.
