For downstream dusty processes, BAT is to reduce emissions using one or a combination of the following techniques:
| A description of the technique is given in Section 1.10.1. | |
| Techniquef1 | Applicability |
|---|---|
| (i) Minimising the losses of product by ensuring a good sealing of the production line, where technically applicable. The potential sources of dust and fibre emissions are:
A good construction, sealing and maintenance of the downstream processing systems are essential for minimising the losses of product into the air | The techniques are generally applicable |
| (ii) Cutting, trimming and packaging under vacuum, by applying an efficient extraction system in conjunction with a fabric filter. A negative pressure is applied to the workstation (i.e. cutting machine, cardboard box for packaging) in order to extract particulate and fibrous releases and convey it to a fabric filter | |
| (iii) Applying a fabric filter system Waste gases from downstream operations (e.g. fiberising, mat formation, lubricant burn-off) are conveyed to a treatment system consisting of a bag filter | |
