BAT is to reduce the production of solid waste to be disposed of by using one or a combination of the following techniques:
| Technique | Applicability |
|---|---|
| (i) Recycling of waste batch materials, where quality requirements allow for it | The applicability may be limited by the constraints associated with the quality of the final glass product |
| (ii) Minimising material losses during the storage and handling of raw materials | The technique is generally applicable |
| (iii) Recycling of internal cullet from rejected production | Generally, not applicable to the continuous filament glass fibre, high temperature insulation wool and frits sectors |
| (iv) Recycling of dust in the batch formulation where quality requirements allow for it | The applicability may be limited by different factors:
|
| (v) Valorisation of solid waste and/or sludge through appropriate use on-site (e.g. sludge from water treatment) or in other industries | Generally applicable to the domestic glass sector (for lead crystal cutting sludge) and to the container glass sector (fine particles of glass mixed with oil). Limited applicability to other glass manufacturing sectors due to unpredictable, contaminated composition, low volumes and economic viability |
| (vi) Valorisation of end-of-life refractory materials for possible use in other industries | The applicability is limited by the constraints imposed by the refractory manufacturers and potential end-users |
| (vii) Applying cement bonded briquetting of waste for recycling into hot blast cupola furnaces where quality requirements allow for it | The applicability of cement bonded briquetting of waste is limited to the stone wool sector. A trade-off approach between air emissions and the generation of solid waste stream should be undertaken |
