1. Conditions of use(1) Standard conditions during use
The number of hours and days of use, based upon amodel of general office PC use, are listed in“Energy-saving personal computers and peripheral
equipment” published by the Japan Electronics andInformation Technology Industries Association (theJapan Electronics Industry Development Association
at the time of publication). Also, measurements should
be carried out with an AC adaptor connected to thepower socket.

the LCI:
Lifecycle
Inventory
analyses•

Active time/waiting time: 4.5 hours per day
Active time/waiting time are defined separately in“Energy-saving personal computers and peripheral
equipment” as active time 3.5 hours, waiting time 1
hour. However, it is considered difficult to distinguishbetween these, so in this standard this grouping istaken to be 4.5 hours. Active time/waiting time isdefined as the condition where the power is ON, but
the function of the device is not operating. At this time
the screen is static. When measuring, the display is at
its brightest.

•

Low power time: 4.5 hours per day
In the international Energy Star program, if there has
been no input or calculation performed for apredetermined length of time, the device is required totransfer into low power mode, which uses less power
than waiting time mode. In this standard, theelectricity consumption in low power mode as requiredby the international Energy Star program is taken to
be the energy consumption in low power time.

•

Number of days of use annually: 240 days
5 days per week × 4 weeks per month × 12 months =240 days of operation per year.
(2) Standard conditions when OFF
The standard conditions for power consumption when
OFF are with the PC turned OFF but with the AC
adaptor connected to the power socket. Calculation of
OFF time shall be made from the number of days of use(240 days) times the number of hours of non-use (15hours per day × 240 days) plus the number of days of
non-use (125 days) times the number of hours of
non-use (24 hours × 125 days).

route scenario, including transportation.
• Product reuse scenario: Each reportingorganization to set• Parts reuse scenario: Each reporting organization
to set• Recycling scenario: Each reporting organization toset, including the material-specific recycling ratio(η).
• Non-reuse/non-recycle disposal scenarios: Eachreporting organization to set
2） For the non-recycling route, the separate document“Disposal scenarios” will be adopted.
2. Deduction scenarios
The separate document “Disposal and recycling
scenarios for products after use (PC version)” will be
adopted.
3. Criteria for determination of recyclability andreusability
Criteria to determine whether a product can be reused
as a product or not shall be set by each reportingorganization for each product type. For each productdismantled without being reused, criteria to determine

obtain this information, the value η1 = 20% shall be
used.
5. Product reuse
Add the impact of the reuse process, including transport
for reuse, and deduct the impact of the manufacture,processing, and assembly of the product’s materials.
(As a rule, the impact of reuse shall be measured)If a product is recycled after a period of longer than 4
years, at the time of determination of reuse a reusededuction ratio of 0.5 shall be set. If components are
replaced, the manufacturing stage impact of theseparts shall be added. Each reporting organization shallset scenarios for after product reuse.
Therefore, the following formula shall be used for the
deduction calculation:.
Product reuse deduction amount = “reused
product’s materials manufacturing impact andprocessing and assembly impact” × “productrecycling ratio η1” × “product reuse ratio” × “reusededuction ratio”
6. Component reuse
Add the impact of the reuse process, including transport
for reuse, and deduct the impact of the manufacture,processing, and assembly of the reused components’materials. (As a rule, the impact of reuse shall bemeasured)
If a product is recycled after a period of longer than 4
years, at the time of determination of reuse a reusededuction ratio of 0.5 shall be set. Each reportingorganization shall set scenarios for after component
reuse.
Therefore, the following formula shall be used for the
deduction calculation:
Component reuse deduction amount = “reusedcomponent’s materials manufacturing impact andprocessing and assembly impact” × “productrecycling ratio η1” × “1 – product reuse ratio” ×“component reuse ratio” × “reuse deduction ratio”
7. It is assumed that during the life of the product there
is no reuse or replacement of consumables.
8. Method of calculating the process impact of products
or components disposed of without recycling or reuse
The separate document “Disposal and recycling
scenarios for products after use (PC version)” will be
adopted.
9. Quality weighting coefficient for recycled materials
In accordance with the separate document “Disposal andrecycling scenarios for products after use (PC version)”
the following quality weighting coefficients (Z) shall be
used, except where a reporting organization has
applied to use their own coefficients.
Metal: Z = 0.5, Glass: Z = 1, Sheet paper andcardboard: Z = 0.9, Others: Z = 0.35

7/8Note 1: PDAs are not included in this PSC because the unit composition is different and the conditions of usage aredifferent:
PDAs do not have hard disk drives, floppy disk drives, CD/DVD drives, and other such memory media, or
keyboards or other input and output devices. Also, the usage conditions differ from the daily hours of use andusage mode given in item 7 “Usage stage information”.
Note 2: The reason the scope of peripherals is limited is that if the scope was the minimum sales unit then, depending
upon the model type, such accessories as a mouse or headphones might be included, and there would be no
uniformity. Also, there is the possibility that various other peripherals would be included in the future.
Note 3: If the performance of a new battery is taken to be 100%, then after recharging in excess of 500 times theperformance falls below 60%, and the product life is considered to be over. This PSC assumes that the product will
be used for 960 days (240 days per year × 4 years = 960 days) in the usage stage and that half of the time (480 days)
it will be used with an AC adaptor and half with battery only. Therefore, the battery will not be recharged morethan 500 times, so it is assumed that the battery will not be changed during the usage stage.
Note 4: In the disposal and recycling stage, PCs for commercial use are postulated. At the present time, recycling of PCs
for home use has just begun, and the situation is not clear. Hence, the established recycling route for commercial
PCs is taken to be representative.
Note 5: As a rule, items containing 10 000 or more transistors are dealt with using the unified basic unit semiconductor
packages. Items with less than 10 000 transistors are dealt with as “Others” as defined in “Item 9-1: Method of
calculating semiconductor circuit boards”, and use the unified basic unit laminated boards.
Note 6: For lithium ion batteries, nickel mercury batteries, and other secondary batteries, use the following method givenin the Digital Camera PSC (AP).
Various types of lithium type (mainly) batteries are used for digital camera products. However, the impact of the
production processes for such various types of batteries cannot be calculated directly, since the Basic Unit data
available from the EcoLeaf Basic Unit database for battery products are presently limited to alkaline–manganesetype (primary), manganese type (primary), and lead–acid storage type (secondary). Therefore, the digital camera
PSC sets out a method by which to calculate the impact by using the formula shown below, based on theassumption that the impact of the battery production process has a correlation to the amount of electrical power
stored (voltage × service capacity)
1.

According to reports by various camera companies, the CR123A, a typical lithium-type battery for camera
products (nominal voltage: 3 V, nominal service capacity: 1300 mAh), provides the same life for camera
products as two LR6 batteries (AA type alkaline-manganese battery) connected in series. In light of this fact,
the impact of producing a CR123A battery can be calculated by using EcoLeaf Basic Unit data “U” (/kg) for an
alkaline–manganese battery as follows:
Environmental Impact of production of a CR123A battery (L) = The impact of producing two LR6batteries (nominal weight: 23.5 g per unit) = “U” × 23.5/1000 × 2
By this logic, the following formula has been set for calculating the environmental impact of various types ofbattery.
The impact of a target battery = “L” × (nominal voltage “V” / 3) × (nominal service capacity “A” / 1300)= “U” × “V” × “A” × 47/3,900,000
