Innovation scenarios in the glass industry in Europe
No full textThe following article is part of broader doctoral research
conducted by the author, concerning innovation and
technologies developed in the glass sector.
Thus far, glass is one of the most widely used materials in
the construction field. The extent of the use of this material
is related to the innovations that have transformed the glass
industry throughout history, from the industrial process to
the final product.
The proposed paper aims to retrace past and present
innovations through the acknowledgment of contemporary
demands with a view to possible future developments of
glass, by analysing the current sectoral targets and the
critical issues that claim for the development of new models,
to reduce the environmental impact of the entire glass life
cycle
Il vetro piano: potenziale inespresso di un rifiuto da costruzione e demolizione
No full textThis contribution is developed within the Ph.D. course conducted by the author
at the Department of Architecture of the University of Roma Tre. The
research has as its focus the development of new mix designs through the
use of recycled glass, as a secondary raw material, to replace classic fine
aggregates of stone origin.
The measures implemented on a global scale, starting from the Sustainable
Development Goals (SDGs) of the 2030 Agenda and the European Green
deal, have highlighted how much the construction sector, throughout its
supply chain, contributes significant percentages in harmful gas emissions.
In particular, recent studies on the state of conservation of Europe’s building
stock have shown how it is one of the most energy-intensive sectors of
the entire industry, in relation to the years of construction.
These aspects will necessarily condition the strategic choices that will have
to be made in this sector, with particular reference to interventions aimed
at the energy efficiency of the building heritage of the 20th century.
The results that, as a consequence of these actions, will lead this heritage
to a lower demand for energy and a lower emission of harmful gases will,
at the same time, contribute to an increase in Construction and Demolition
waste. This contribution, given these predictions, will evaluate, with particular
reference to glass as a secondary raw material from windows and
doors, the possibility of its reuse for new mix designs in a circular economy
perspective
Il riciclaggio come propulsore innovativo nel settore produttivo del vetro
No full textOne of Europe’s most important goals is to become the first carbon
neutral continent in 2050. In 2019 the building and construction sector
has been accounted 50% of greenhouse gases.
Currently in Europe, more than 50% of the building stock dates back
to the 1970s.
One of the measures needed to improve the environmental performances
in buildings is to intervene on theirs envelopes and windows.
To this day, glass production in Italy and Europe is growing steadily,
demonstrating that this material is of great interest in all its applications.
The largest production sector is food glass, which accounts for
2/3 of total production, and the second largest is flat glass, mainly used
in the construction sector.
If we look at the building stock, we can see that most of these windows
and doors are now inadequate to fulfil the requirements and will have
to be replaced.
In addition to glass production, the recycling of glass is a growing sector.
Starting from the characteristics of this material, which is 100%
recyclable, and analysing the existing building stock, this paper aims
to investigate the possibility of replacing old windows and doors with
glass recycling.
Flat glass, a post-consumer material, difficult to recycle, could be integrated
with positive results into the production process, reducing the
greenhouse gas emissions and the consumption of raw materials

Il calcestruzzo fotoluminescente. L’innovazione materica applicata alle infrastrutture viarie
No full textAll over the world in 2019 the production of cement and concrete increased: this
positive trend differs within the world panorama; China is the largest user of these
materials with over 50% of consumption and in Europe and in Italy, with concrete
still have a great demand.
For the production of this binder and conglomerate, the demand for raw materials
from extraction is very high, reaching a percentage of over 60% for concrete
aggregates only.
As a possible solution to this great material demand, research has been carried
out over the years for the use of recycled materials.
This replacement is now a common practice that sees the use of recycled
aggregates in the packaging of new concretes. The use of recycled aggregates
throughout history has always proved to be a useful tool for material demand.
Today this practice is regulated and set between national and international
objectives, preferring a circular economy based on the minimum waste.
The research carried out for the re-use of secondary raw materials have
contributed to the development of many innovations, in particular the product with
new concretes with specific characteristics derived from the inclusion of secondary
raw materials of different nature.
One of the most interesting product innovations is photoluminescent concrete. This
is achieved by mixing binders, recycled aggregates, water and recycled glass. This
particular composition, following a thermal process, gives the concrete the physical
phenomenon of phosphorescence, allowing this conglomerate to absorb solar
radiation and release it after hours in the form of a natural light source.
Thanks to this characteristic, in Europe, cycle paths have been created with the
use of this conglomerate. It would find a potential application for pavements and
urban components such as highway or airplane runway with a relevant contribution
in term of environmental benefit
