Reduction in CO2 Emissions And Cost Saving In Glass Manufacturing

reduction in CO2 emissions, combined with significant cost savings may be possible for glass manufacturers

Glass Technology Services have demonstrated that a reduction in CO2 emissions, combined with significant cost savings may be possible for glass manufacturers through batch reformulation.

Carried out in partnership with Sheffield Hallam University, the EnviroGlass project proposed that substantial saving may be possible and has successfully demonstrated proof of concept for the substitution of raw materials with waste streams from other sectors – reducing energy demand, emissions and waste and contributing toward the circular economy.

In one amber glass exemple, these waste streals would replace raw materials at up to 8wt% while reduction furnace temperature by up to 39°C. Further benefits included reduction in NOX emissions, refractory wear, landfill and transportation as well as a faster melting rate due to the form of elements in the wastes studied.

In UK glass production, this could equate to annual savings of over £500,000 in energy cost, combined with a 35 GWh/year reduction in energy demand and a 42kT/year reduction in CO2 emissions.

Glass Technology Services routinely work with manufacturers to troubleshoot and optimize batch and melting operations, but the EnviroGlass project set out specially to investigate the challenges identified withing the glass indistry’s 2050 decarbonisation roadmap and identify cost-effective routes to achieve decarbonisation.

If you are working in the glass, energy from waste and combustion technology sectors, and would like to be involved in the next phases of the project, EnviroGlass 2, contact Glass Technology Services Ltd on

We’re exhibiting at #PharmapackEU on 6-7 Feb 2019 – Europe’s dedicated event for #pharmaceutical #packaging, drug delivery & innovation.

Visit booth G30 to see how we can support your quality assurance, compliance & operational teams.


TY @Glass_Int – it’s a new course, building on feedback from #GlassAppreciation, focusing entirely on #ContainerGlass #Packaging and geared towards #PackagingTechnologists and those working within branding and retail to understand specification, testing and design.


A really useful course for anyone interested in glass….
