• Production of container glass/glass wool (SNAP 030315/030316/040613).
• Production of mineral wool (SNAP 030318).
• Limestone and dolomite use (SNAP 040618).
• Roof covering with asphalt (SNAP 040610).
• Road paving with asphalt (SNAP 040611).
The time series for emission of acidifying substances, heavy metals, NMVOC
and particulate matter from 0LQHUDO SURGXFWV (NFR 2A) are presented in Table
4.2.
The emission of NOX from production of container glass is increasing
slightly until 2004 and thereafter decreasing significantly whereas the emission
of CO is decreasing in the period 1990-2010. In the same period of time,
the activity is nearly constant. Emissions of both substances are related to
combustion/process conditions and will be investigated further. Emissions
of the heavy metals lead, selenium and zinc are related to the raw materials
used. Recycled glass constitutes a considerable part of raw materials and,
therefore, the quality/purity of the glass is a determining factor. Emission of
lead shows a decreasing trend that is in accordance with the attempts to
avoid lead in glass as well as in wine bottle seals.
Production of glass wool is expected to result in emission of approximately
the same pollutants as in production of container glass. Emission of NH3
from production of glass wool and mineral wool shows a decreasing trend
from 1990-2010 as can be verified by the decreasing emission pr amount
produced.
