2. STEP 1
MFA TASK FORCE MAY 2012
Estimate products available for domestic uses (Apparent consumption: production-exports+imports) by product.
Split the Domestic Production of each of the 266 product groups of the Supply table by using the composition by product (eg. at the 8-PRODCOM-digit level for industrial goods)
Calculate Apparent Consumption at the most disaggregate level possible, by exploiting the links established with trade statistics

3. Further steps
MFA TASK FORCE MAY 2012
Information has been kindly provided by Statistics Norway on:
how much of each product will appear in the waste stream in the years following its production (in % of the total weight)
[For the Σ to be 1 for all products, it is necessary to consider products that are embodied in other products , some of which do not emerge in the waste stream in the time window we can consider];
WITH LONG ENOUGH TIME SERIES OF PAST APPARENT CONSUMPTION AT HAND, THIS INFORMATION CAN BE USED TO ESTIMATE POTENTIAL WASTE GENERATION
The composition by material of each product (paper; glass; metals…; in % of the total weight, Σ = 1)
THIS INFORMATION CAN BE USED TO ESTIMATE POTENTIAL WASTE GENERATION BY MATERIAL (POTENTIAL FOR RECYCLYING )

4. Critical raw materials – steps
MFA TASK FORCE MAY 2012
Given the estimate of the quantity (tons) of product i available in year j (for j = 2000 to 2010):
Determination of average content of critical material k per ton of product i (Cki);
Determination of year j’s final domestic uses (Uij) of the products for which Cki > 0 (apparent consumption);
Determination of the part of Uij contained in the waste streams of the years j+t (Wi (j+t), t=0,1,2...; ΣtWi (j+t) = Uij)
Critical material k contained in Wi (j+t): K(Wi (j+t)) = Cki*Wi (j+t)
Critical material k in the waste stream of year h (h=2008 onwards; K(W)h ≈ Σi K(Wi (j+t)) where j+t=h)
