The MEIGLASS project developed a very new technology that allows to reuse the glass cullet rejected by the primary cullet beneficiation units and that, in the past, was entirely land filled.
SASIL has been able to collect 200.000 ton/year of the above mentioned rejects achieving an evident and important direct environmental benefit.
A secondary contribution to the environment is due to the reduction of specific energy consumption of the glass melting furnaces, who were beneficiaries of 70 % of these rejects. As a consequence of the lower fossil combustible use and the reduction of the fire losses of batches fed to the glass containers furnaces, green house gases emissions were significantly reduced, CO2 with about 54.000 ton/year.
Moreover the recycling of 190.000 tons of treated glass, substituting the natural raw materials employed before in the glass containers, ceramic and brick industries allowed to reduce the extractive impact of the natural raw materials mines.
NOVEDI, NO VEtro in DIscarica (No glass in landfill), had as main project objective to demonstrate the feasibility to reduce to zero the glass rejects that do not come from cities’ collections and that, due to their particular chemical compositions cannot be recycled, neither to the glass container factories nor to the ceramic industry. These glass rejects are actually destined to landfilling. The project demonstrated new technologies which allow its implication in the production of glass based insulation materials with a high performance in thermal insulation, mechanical strength, fireproof and eco-compatibility, which traditional production used to be too expensive for an introduction on market scale.
NOVEDI has enabled the reuse of these glass rejects into foam glass, a porous gravel of apparent density of 0,2 kg/liter, with remarkable characteristics of thermal insulation usable in the building sector. Use of such foam glass as inert in the composition of lightweight structural concrete (density 1800 kg/m3) and super-lightweight insulating concretes (density 1000 kg/m3) has been demonstrated in the realisation of a demonstration building with a foreseen energy consumption of 15kWh/m2/year.
For the construction of this building 80.000 kilo of recycled glass has been used, composed of 85% soda lime glass rejects; 5 % front monitor glass rejects; 5% fiber glass rejects and 5 % of a mixture of lamp and artistic glass rejects.
The VALIRE project aimed to valorise slag and ashes produced by municipal waste incinerators and currently landfilled by producing foam glass, fiberglass, concrete filler, fluxes for ceramic industry and raw materials for brick industry.
Starting from a physical-chemical in-depth examination of the bottom ashes, a treatment process has been developed , partially wet and partially dry, to separate the fine and coarse fractions, crystalline and amorphous, to provide new secondary raw materials for the manufacture of the products mentioned above. For fly ashes, due to the high content of chlorine and sodium, pre-treated ashes have been taken into account with low content of these elements. Through contacts with the operators of treatment plants for MSW (municipal solid waste) and primary treatment plants of slag, some synergies have emerged, enabling Sasil to deal with specific treatment technologies and find new potential business opportunities for slag that is still produced in excess with respect to the current receptivity of the market.
Photovoltaic panels Mobile Recycling Device (PV Morede)
Funded by the 2012 Eco Innovation Programme, PV Morede researches into the development and industrialization of a patented mobile recycling device.
Compared with other industrial waste systems, PV Morede is able of treating PV modules directly where they are installed, allowing a cost-effective and easily accessible waste treatment for small quantities of PV panels.
Cradle-to-cradle sustainable PV modules (CU-PV)
CU-PV is a pan-European R&D project under the European Union’s FP7 Programme. With the goal of improving the environmental profile of silicon based PV modules, the CU-PV partners investigate the reduction of silver and lead in PV, ways to eco-design and high-value end-of-life treatment.
Bringing research, production and waste treatment partners to this project, CU-PV covers the entire life cycle of a silicon based PV module.
Innovative PRImar MEasures for reduction of NOx emissions and Energy consumption by glass furnaces
The PRIME GLASS project aims to trial and demonstrate technologies that will significantly improve environmental impact of the glass industry, reducing NOx, CO2, CO sulfur oxides and dust emissions and energy consumption.
It will develop and test applicable and effective solutions for:
- NOx containment at the source during the combustion proces
- Combustion optimization in regenerative and hybrid glass furnaces by increasing heat exchange
Moreover, it will demonstrate advantage of infrared thermography applied to the glass furnace, offering a quantitative monitoring of the temperature field in the melted glass and in the flame structure.
