In January 2003 Nordson Benelux B.V. delivered upon request by Senter together with a consortium of four other Dutch companies, a complete boiler enameling plant based on Ferro’s electrostatic dry powder enamel technology to Leov Company in Veles, Macedonia in order to replace their environmental unfriendly galvanizing process.
Depending upon the selected enameling process, industrial porcelain enameling (UK: vitreous enamelling) may generate the following emissions :
- solid waste
- waste water
- gaseous emissions
The easiest way to avoid emissions is to select the most environmental friendly enamel process.
Instead improving process efficiency and in-house recycling should help to reduce the overall emission.
Examples of waste reduction initiatives are the introduction of cascade rinsing
at pretreatment plants and switching for wet spraying to electrostatic dry powder application.
Some examples of emission treatment are in-house waste water treatment plants, fluorine scrubbers, etc.
This aspect, which may result in optimizing the energy consumption of various equipments & re-utilization of waste heat, is driven by the global trend of continuous increasing energy cost. [More..]
