2.3.1 INTRODUCTION
Lebanon, in its recovery process from after the war has made efforts
to actively participate in international forums related to the
environment and the climate. Studies aimed at understanding the
causes of environmental problems and their societal impact are now
favourably supported by the Government of Lebanon, universities and
non-profit groups. Industrial sector is one of the targeted sectors
for survey and assessment study of its environmental implications
through waste production and disposal. In 1994, industry in Lebanon
accounted for 14% of the total GNP compared to agriculture
accounting for 26% and the service sector accounting for 60%.
This work objective is to conduct a greenhouse gas emission
inventory of the industrial processes in Lebanon for the year 1994.
Six gases are known to be significant greenhouse gases: carbon
dioxide (CO2), methane (CH4), nitrous oxide (N2O), nitrogen oxides (NOx),
carbon monoxide (CO) and non-methane volatile organic compounds (NMVOCs).
Industrial sources in Lebanon, which contribute to significant
emission of these gases, are identified through IPCC guidelines
(Intergovernmental Panel on Climate Change) and emission estimates
are reported in Standard Tables format. Sulphur dioxide (SO2)
emission sources and emission estimates are also reported for
Lebanon. Other gases that do not occur naturally are the
Chlorofluorocarbon and halons, which are used in refrigeration,
air-conditioning, foam and solvent production. These gases are
already being phased out worldwide.
For 1994 the inventory of the industrial processes uses
methodologies taken from IPCC Reference Manual on Guidelines for
National Greenhouse Gas Inventories [1]. The sources of the compiled
data have been obtained either from official governmental reports or
directly from the concerned industries. The inventory has focused on
the following relevant industries to greenhouse gas emissions in
Lebanon:
- Cement production
- Lime production
- Road paving asphalt, and roofing asphalt
- Glass production
- Chemical compounds which include mainly sulphuric acid,
fertilisers and plastics.
- Steel products where raw iron is imported.
- Aluminum shaping and extrusion factories.
- Paper & printing (raw material of dried pulp is imported).
Food processing which includes processing of local crops for sugar
and wine production. It also includes meat and poultry and
margarine. For the processes of bread making and coffee roasting,
the wheat and green coffee are mainly imported.
The amounts of greenhouse gases released to the atmosphere via the
above-specified industrial processes have been estimated using the
IPCC methodology and emission factors. Where national emission
factors varied from those of IPCC, the factors are discussed.
2.3.2 THE INVENTORY PROCESS
The inventory proceeded by identifying the process and emission
greenhouse gases sources in the Lebanese industry. The industrial
firms surveyed are: the cement production, lime, chemical products,
asphalt roofing, paper and printing, cosmetics, foam and plastics,
iron and steel, aluminum extrusion and food and drinks. A list of
the industrial firms to be surveyed was prepared. Forms were sent to
each specific industry requesting information about their production
of relevant components of interest and the type and amount of fuel
used in 1994 and the following years as available. Data was obtained
from several sources for comparison with other industrial census and
surveys conducted in Lebanon and reported by the Lebanese
Government.
The first part of this sectoral report is concerned with emission
estimations for each type of industry emitting greenhouse gases. The
verification procedures used to check data are also reported. The
completed set of inventory worksheets of IPCC on industrial
processes is compiled in the Appendix.
2.3.3 ESTIMATIONS OF EMITTED GREENHOUSE GASES FROM VARIOUS
INDUSTRIAL PROCESSES IN LEBANON (1994)
A. CEMENT PRODUCTION (CO2 & SO2 EMISSIONS):
There are two Portland cement plants and one white cement plant in
Lebanon. Data was available on the total production of cement in
1994 from the Administration of the Statistical Centre of the
Council of Ministers [3]. The data inspected reported that the
fraction of lime in the cement produced in Lebanon is between 0.6
and 0.65. The value of 0.635 is used in our calculations of the
emission factor (t CO2/ t cement produced). This is also the same
default value reported in the IPCC guidelines for estimating
emission factors of CO2 from cement, [2].
Worksheets 2-55 the Appendix give the estimated emissions of CO2 and
SO2 due to cement production in Lebanon in 1994.
B. LIME PRODUCTION (CO2 EMISSIONS):
The companies that produce lime in Lebanon are the Lebanese Lime &
Plaster Factory and the Middle East White Cement Factory. Data on
lime production for 1994 has been obtained directly from the Lime
Factories as shown in Table 2.23. |

The lime produced in
Lebanon uses a kiln-calcite feed which has an emission factor of
0.79 tons of CO2 per ton of quicklime produced [2,pp2.5].
Worksheet 2-56 of the Appendix presents the data for CO2
emissions due to quicklime production in Lebanon in 1994.
C. SODA ASH USE (CO2 EMISSIONS)
Soda ash is
not produced in Lebanon. It is imported and is mainly used in glass
production. There are two major glass producers. One is located in
Shuwaifat and the other in Shtura. The ratio of soda ash quantity
used in tons per ton of glass produced was calculated as 0.169973,
based on information provided by the factories. The details of the
data are given in Table 2.24. |

In 1994, the
container glass production in the Shuwaifat factory was 32,211 tons
and the soda ash used was 5,475. The Shtura factory produced 23,819
tons of container glass in 1994 and so the soda ash used is
calculated as 4,048.6 tons.
The flat glass production was of 15,000 tons, which uses 2,549.595
tons of soda ash. So the total soda ash used in 1994 was 12,072.6
tons.
Worksheet 2-58 of the Appendix presents the data for CO2
emissions due to soda ash production and use in Lebanon in 1994.
D. PRODUCTION & USE OF MISCELLANEOUS MINERAL PRODUCTS:
D.1
Asphalt Roofing Production (NMVOC & CO Emissions)
There is one asphalt-roofing plant in
Lebanon (CMC Construction Material Company SAL). The company imports
the material and provides no data. The emissions from asphalt
roofing production are estimated from the national total imported
mass of the product. The data is obtained by considering the amount
of asphalt imported as raw material. It is reported that in 1993,
51,000 tons of asphalt were imported, 108,839 tons in 1996 and
87,585 tons in 1997 [4,5]. The amounts of asphalt used as raw
material for road paving is obtained from the Ministry of Public
Works given in Table 2.25, for the years of 1994 through to 1996.
The South Council and the Council for Development and Construction
(CDR) also use comparable amounts of asphalt for road paving. Since
road paving has been a major activity in 1994, it is acceptable to
assume that 80% of imported asphalt is used for road paving and 5%
is used for asphalt roofing. |

According to IPCC
guidelines it is possible to assume that all of the asphalt not used
for road paving is blown [2]. The emission factor in kg NMVOC/ton
asphalt roofing produced is taken as 2.4 for a no control blowing
process, using table 2.3 of IPCC guidelines [2]. The emission factor
for CO is taken for a blowing process as 0.0095 using Table 2.2 of
the IPCC guidelines [2].
Worksheet 2-59 (1&2) of the Appendix present the data for NMVOC & CO
emissions due to asphalt roofing production and use in Lebanon in
1994.
D.2 Road Paving With Asphalt (NMVOC Emissions)
The quantity of road paving material used in Lebanon by the Ministry
of Public Work in 1994 has been 10586. There are two other major
sources of road paving asphalt: the South Council and the Council
for Development and Construction. The total quantity used in road
paving is estimated from the amount of asphalt that was imported in
1994. The data is shown in Table 2.25. The emission factor of 0.023
kg of NMVOC per ton of paving material used in the asphalt plant, is
obtained from IPCC guidelines reference volume [1]. The emission
factor of 320 kg of NMVOC per ton of paving material used in the
road surface, is obtained from the IPCC guidelines reference volume
[1].
Worksheet 2-59 (3) of the Appendix presents the data for NMVOC
emissions due to asphalt road paving in Lebanon in 1994.
D.3 Glass Production (NMVOC Emissions)
The total amount of container glass produced in Lebanon is already
reported from the factories and is given in Table 2.24 of this
report. The flat glass production amount is obtained using a maximum
production capacity of 1.86 Million m2/year of
flat-glass, [5]. This is converted to tons using an average glass
thickness of 5mm and an average density of 27700 kg/m3 ,so
that the estimated glass production in tons = 1.86 x thickness
0.005* density*1000. Assuming that the flat glass production is at
60% of its maximum value, then a final value is obtained for glass
production in tons in 1994. The emission factor of 4.5 is obtained
from the revised 1996 IPCC guidelines [1].
Worksheet 2-59(4) of the Appendix presents the data for NMVOC
emissions based on total amount of glass produced in Lebanon in
1994.
E. PRODUCTION OF CHEMICALS
E.1 Production of Sulphuric Acid (SO2 Emissions)
The only chemical produced in Lebanon that contributes to greenhouse
gas emission is the sulphuric acid. The amount of sulphuric acid
produced in Lebanon is reported to be 135,000 tons per year [6]. It
was extremely difficult to get data directly from a list of 5 major
chemical producing companies. The companies do not disclose such
information so as not to be liable for pollution.
Worksheet 2-10 (5) presents the data for SO2 emissions
based on the total quantity of sulphuric acid produced in Lebanon in
1994.
F. IRON & STEEL PRODUCTION (CO2, NOX, NMVOC,
CO& SO2 EMISSIONS)
The total production capacity of steel mills in Lebanon is of
480,000 tons [5]. The total amount of raw iron imported to Lebanon
was 273,965 tons in 1994, [3]. It is assumed that all imported raw
material is used by the factories. The density of produced steel is
about 98% of the raw iron due to the added carbon in the steel
processing using rolling mills. One ton of raw iron produces on
average about 1.015 tons of steel. So the total estimated steel
production for 1994 is 278,074.5 tons. The emission factors used for
green house gas production per ton of steel produced are obtained
from tables 2-13 to 2-16 in the 1996 IPCC Guide Lines, [2].
Worksheet 2-65 (2&3) of the Appendix presents the data for CO2
, NOx, CO, NMVOC and SO2 emissions based on
the total quantity of steel produced in Lebanon in 1994.
G. PULP & PAPER INDUSTRIES:
Paper industry is one of the major industries in Lebanon. It does
not involve the production of dried pulp. The pulp is imported from
other countries.
H. FOOD & DRINK (NMVOC EMISSIONS):
H.1 Alcoholic Beverages:
Wine and beer are produced in Lebanon. Data has been obtained
directly from the factories for the year 1994 and is shown in Table
2.26. Emission factors in kg NMVOC/ per hl beverage produced are
obtained from table 2-25 in the 1996 IPCC Guidelines, [2]. Worksheet
2-67 (1) of the Appendix presents the data for NMVOC emissions based
on the total quantity of alcoholic beverages produced in Lebanon in
1994. |

H.2
Bread and Other Food Products:
Emission factors in kg NMVOC/ per ton of food produced are obtained
from table 2-26 in the 1996 IPCC Guidelines, [2]. The main food
processing industries in Lebanon include meat and poultry,
margarine, biscuits and cakes, bread and coffee roasting.
Meat and Poultry production is obtained from the Arab Union of Food
Industry Report, page 21, [7]. The production in 1991, 1992, and
1993 was 79,000, 80,000 and 80,000 tons respectively. It is also
assumed to be the production of the year 1994.
Sugar production is obtained from two references, one is from the
Arab Union of Food Industry Report,[7] and from the Trade
Information Centre, Ministry of Economy and Trade.
Margarine production is obtained from the Arab Union of Food
Industry Report, pages 14 & 48 in Tables 7 and 17 of Reference 7.
The total production of olive oil in 1994 was 8000 tons. It is
subtracted from the total production of margarine and oil which was
29,590 tons. This gave margarine production of Lebanon in 1994 as
21,590 tons.
Biscuits, cakes and bread are produced from wheat. The total amount
of wheat imported and produced in Lebanon was 389,000 tons. Seventy
five percent was used for bread production and 25% was used for
cakes and biscuits. The amount of wheat used for bread making was
multiplied by a factor of 1.2 based on the fact that each kg of
wheat produces 1.2 kg of bread.
The amount of green coffee imported to Lebanon in 1994 is obtained
from Reference 7, page 34.
The emissions of NMVOC are presented in worksheet 2-67 (2) of the
Appendix based on the total quantities of various types of food
produced in Lebanon in 1994.
I. EMISSIONS RELATED TO PRODUCTION OF HALOCARBONS AND SULPHUR
HEXAFLOURIDE:
Lebanon imports all its needs of HFC’s and PFC’s for use in the
refrigeration, air conditioning applications, in the aerosol,
solvents and foam industry, and in the fire fighting sector. Those
sectors are using the Ozone Depleting Substances. Lebanon has only
recently ratified the Montreal Protocol on March 31, 1993. Since
then Lebanon has been working in a country program for applying
phase out measures on these substances. In 1994, the phase out
process was not yet enforced. The ban on imports and use of the
Ozone Depleting Substances started only in 1996. A chemical
substitute of these substances such as HFC134a was imported in small
amount (2 tons) to Lebanon in 1993, [8]. It is assumed that in 1994,
also an equal quantity was imported. The quantities of HFC’s
imported are expected to increase substantially in the following
years after the ratification of the Montreal Protocol (1993) and
they have to be included in any future inventory. In this report
only the bulk potential halocarbon emissions is calculated based on
the amount imported [1,2]. This is summarised in Worksheet 2-69
(1-3) of the Appendix. No information or data was available on
product imports and exports of items containing halocarbons and
sulphur hexaflouride for the year 1994. Actual emission estimates of
these gases were not possible.
2.3.4 CLOSURE OF THE INDUSTRIAL PROCESSES INVENTORY
In 1994, the Lebanese industry emitted 1924.063 Gg (1,924,063 Tons)
of carbon dioxide, 0.0003 Gg (300 Tons) of carbon monoxide, 0.01112
Gg of nitrogen oxide, 273.888 Gg (273,888 Tons) of non-methane
volatile organic compounds and 3.382 Gg (3382.6 Tons) of sulphur
dioxide.
Uncertainties and limitations are associated with the estimated
greenhouse gas emissions. The emissions reported for industrial
processes in Lebanon reflect current best estimates. Thus the
reported emissions inventory provides a foundation for the
development of a more detailed and comprehensive Lebanese inventory
in the future. Specific limitations include: a) Quantitative
estimates for some sources of greenhouse gas emissions were not
always based on data obtained from specific sources, but from bulk
imports of certain products; and (b) the accuracy of the inventory
estimates relies heavily on emissions factors available from the
IPCC Guidelines [1,2]. These factors are used in the Lebanese
inventory. These factors may differ for some local industrial
processes because of differences in the raw material used.
