RESOURCES
RULES OF READING (TABLE 1.4)
The overall scope of the table is Cradle-to-Gate, from the raw materials are harvested until the products are ready to be sent from thefactory.Cradle-to-Site can be estimated by supplying with info from Table 1.2. Utilization of the combustion value is the hot spot in the rest of the life cycle (Site-to-Grave) and is therefore also mentioned..
Empty squares indicate that adequate information is missing and '-' signify that specification is irrelevant.
AD COLUMNS
Column 1 The choice of additives as fungicides, flame retardants etc is not specified, but still can have a large impact Column 3. The numbers refer to information given in Table 1.1. Column 4 Embodied energy is defined asthetotal consumption of energy from the extraction of raw materials until the finished product, including the combustion value of the product itself. It is assumed that waste materials are used as energy sources or as raw materials for other processes and products. The preserved combustion value can eventually be subtracted when the material is incinerated for energy recovery as waste. Brackets indicates that the combustion value is less available due to additional flame retardants and/or substances of toxic character.
Column 5 Describes the amount of water which will have its quality drastically reduced as a result of the production. Recycling or purification of water is not taken into consideration.
