Summary on Grant Application Form
The global glass manufacturing sector uses 140 - 220 Terawatt-hours of energy and emits 50-60 million tonnes of CO2 per

year. Manufacturing inefficiencies are such that, without intervention and increased product demand, global CO2

emissions from glass making are forecast to increase by 20% by 2019. In the UK alone the glass industry produces over 3

million tonnes of glass per year, using 4.5 Terawatt-hours of energy (1.4 Megawatt-hour per tonne of glass melted), and

emits 2 million tonnes of CO2. The energy required for melting glass in a furnace accounts for 75% of the energy

consumption. Melting furnaces typically have 50-60% efficiency, however, the introduction of recycled glass (cullet)

significantly reduces glass melting energy requirements and CO2 emissions. The availability of quality cullet is an industrywide

challenge - 20% is rejected every year and sent to landfill.

We are proposing a feasibility study for a novel briquetting process that will turn rejected cullet (fines) into valuable waste

material re-introduced into glass manufacture. The proposed technology has potential to (i) reduce the glass industry's CO2

emissions by up to 8%; (ii) Secure the long term UK & global supply of cullet and (iii) reduce the industry's energy costs by

4-8%. This application is for a lab based project utilising a test briquetting line, with laboratory scale glass melting and testing equipment. The project feasibility steps will be as follows: (1) exploration of the materials and binders required to

achieve optimum speed and efficiency of glass raw materials melting in the furnace; (2) determining the physical, chemical

and dimensional requirements of the briquettes for manufacturing and processing purposes, and how the briquetting line

needs to be designed to accommodate these; (3) lab scale glass melting trials to determine the effect of the briquettes in

the furnace; (4) characterisation and analysis of the resulting samples to understand the impact of the consolidated cullet

and binding materials on the quality of glass produced vis-a-vis energy consumption; (5) energy and cost savings analysis

to determine the environmental and cost implications of each briquette permutation; and (6) Dissemination of findings.
