# Commission Implementing Decision of 28 February 2012 establishing the best available techniques (BAT) conclusions under Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions for the manufacture of glass (notified under document C(2012) 865) (Text with EEA relevance) (2012/134/EU), Division 3

Extent: E+W+S+N.I.

BAT is to prevent, or where that is not practicable, to reduce diffuse dust emissions from the storage and handling of solid materials by using one or a combination of the following techniques:
I.. Storage of raw materials
(i) Store bulk powder materials in enclosed silos equipped with a dust abatement system (e.g. fabric filter)
(ii) Store fine materials in enclosed containers or sealed bags
(iii) Store under cover stockpiles of coarse dusty materials
(iv) Use of road cleaning vehicles and water damping techniques
II.. Handling of raw materials
Technique
Applicability
(i)
For materials which are transported by above ground, use enclosed conveyors to prevent material loss
The techniques are generally applicable
(ii)
Where pneumatic conveying is used, apply a sealed system equipped with a filter to clean the transport air before release
(iii)
Moistening of the batch
The use of this technique is limited by the negative consequences on the furnace energy efficiency. Restrictions may apply to some batch formulations, in particular for borosilicate glass production
(iv)
Application of a slightly negative pressure within the furnace
Applicable only as an inherent aspect of operation (i.e. melting furnaces for frits production) due to a detrimental impact on furnace energy efficiency
(v)
Use of raw materials that do not cause decrepitation phenomena (mainly dolomite and limestone). These phenomena consist of minerals that ‘crackle’ when exposed to heat, with a consequent potential increase of dust emissions
Applicable within the constraints associated with the availability of raw materials
(vi)
Use of an extraction which vents to a filter system in processes where dust is likely to be generated (e.g. bag opening, frits batch mixing, fabric filter dust disposal, cold-top melters)
The techniques are generally applicable
(vii)
Use of enclosed screw feeders
(viii)
Enclosure of feed pockets
Generally applicable. Cooling may be necessary to avoid damage to the equipment
