The conference is designed for both suppliers and users.

It is for raw material suppliers to inform the users in more detail of their products, what they are and what is required to obtain the quality offered and for the users to describe in more detail their preferred requirements and the reasons for these.

It is also for the users to explain why they are looking for alternative materials, both to reduce carbon input and to reduce the amount of carbon burnt as fuel . These alternative materials may be especially more recycled glass from consumers but also possibly from other industrial processes.

The conference starts with a presentation from Richard Hulme of Guardian, outlining why we are where we are now, in terms of glass compositions. He will discuss why it is difficult  to change them radically, hence, replacement materials will generally be ones that result in compositions within the present range we have now.

Speakers from Sibelco and Lochaline Quartz Sand (LQS) and Newport Industries will describe their operations and product qualities whilst NSG will be describing how they make glass from very different raw materials (especially sand)  in different parts of the world and all for the same end uses. Stoelzle also will be showing how they source different raw materials for making high quality glass in several different countries.

Both Sibelco and FIC will discuss what changes may need to be made in raw material quality, particularly grading, if, as seems likely, electric instead of fossil fuel melting becomes more prevalent.

The main driving force is of course carbon reduction with a big focus on recycling – papers from Glass Technology Services and Sheffield Hallam University will focus on this aspect, and from different kinds of materials by using by-products of other industrial processes (Ardagh Glass) and British Glass.

Electric melting is assumed to be generated in future from non renewables such as wind, solar, tidal (?) but could also be from industrial nuclear energy plants being described by John Lillington.

If we cannot eliminate the CO2 content of raw materials, nor entirely eliminate fossil fuel use, then a paper from C – Capture will show that a process of CO2 removal from waste gases is being used presently at Drax Power Station near Selby Yorkshire.

Is there really a worldwide shortage of sand?

What reserves do we have left in the UK for glass making sand?

How much of these reserves will we be able to access for mining or quarrying due to environmental and/or planning constraints?

In this context, how important are the Scottish sand deposits?

If insufficient reserves at an economic cost are not available in the UK, where might we go next?

All these questions will be addressed at the forthcoming conference at Cambridge  September 3rd and 4th  by Ruud Dorscheidt of Sibelco, Clive Mitchell of the BGS (British Geological Survey) and Diego Zurolo of LQS (Loch Aline Sand Mine)
