In the absence of experience
with implementation of projects in this sector, and pending a judgment by TEAP
on the classification of CFC-11 use in tobacco expansion as a process agent,
the following draft guidelines are conceptual at this stage.
Capital costs
Industry sources informed the
Secretariat that the main part of CFC-11 based equipment cannot be used when
switching to CO2. Therefore, new production equipment suitable for
CO2 must be installed.
If the same methodology used in
the Philippines tobacco expansion project were to be applied, the baseline cost
would be either the cost of new CFC-11 expansion equipment calculated as a
future payment and discounted to the present year; or the depreciated value of
the existing CFC-11 expansion equipment, whichever amount is higher.
Capacity of CFC-11 expansion
process (baseline equipment) and that of CO2 process should be the
same. If the minimum capacity delivered by the CO2 process is higher
than the baseline, the difference should be calculated and accounted for as a
capacity increase. This capacity increase should be quantified and deducted
from the capital cost.
Thus, the eligible incremental
capital cost (ICC) should be calculated according to the methodology adopted by the Executive Committee at
its Eighteenth Meeting (UNEP/OzL.Pro/ExCom/18/75 Decision 18/25):
IC = [CC
- NPV(FI)] + NPV[FBb - Fbp]
where,
IC is the incremental cost
CC is the capital cost of the
conversion project
FI is future baseline
investments (that would have occurred absent the conversion).
Fbb is the future baseline
benefits (that would have occurred absent the conversion).
Fbp is the future
benefits of the conversion project
NPV
refers to the net present value of a stream of costs/benefits
The projected investment and
benefits profiles of the enterprise (with and without the conversion project)
should be reviewed by the technical reviewer and the Implementing Agency to
ensure broad consistency with the technological and commercial practices of the
enterprise.
Capital costs should not include
costs of patents.
Operating costs
The two major components of
operating costs/savings in tobacco expansion are the patent royalty fee,
applicable to both CFC-11 and CO2 processes, and the costs
associated for raw materials, energy and labour.
In some cases, the license
agreement for the G-13C equipment stipulates a royalty fee of US $0.10 per
pound on all tobacco treated, and has a duration of the last-expired G-13C
patent unless terminated earlier. In other cases, the license agreement
stipulates a royalty fee of US $0.12 per pound for the first 50 million
pounds, and US $0.09 for each pound produced thereafter for the lifetime
of the patent. It is to be noted that if royalty fees were to be passed on to
the end-user, the incremental cost per package of cigarettes would be about US $0.004.
The license agreement between
the technology provider and the enterprise is, however, negotiable. It may
depend on several factors, which include inter alia, the existing license
agreement, expiration date, equipment capacity and production. However, the
Executive Committee is requested to decide whether royalty fees should be paid
for by the Multilateral Fund for this sector.
The amount
of raw materials, electricity and fuel used for tobacco expansion varies
depending on the compound used for expanding tobacco. The higher expansion
ratio achieved by the CO2 process will result in 25% less tobacco
compared with the CFC-11 process, as indicated by industry sources. Table 1
demonstrates the operating costs of the two technologies as applied to a plant
that processes 5.9 million kilograms of raw tobacco. Information in this table
could be used as a guide in the calculation of incremental operating
costs/savings.
