Multi-functionality and allocation Sample Clauses

Multi-functionality and allocation. ‌ Coke production, pig iron production, and steel production are multifunctional processes meaning that they represent a unit processes yielding more than one functional flow. In this case all three multifunctional processes are an example of a co-production process, i.e. a process producing more than one valuable product as output. The functional flow of a process is a flow that constitutes the goal of the process, in other words, the product outflows of a production process (Guinée et al. 2002). In the processes mentioned above, coke and COG, pig iron and BFG, steel and BOFG are co-produced, respectively. The non-functional flows of a multifunctional process, i.e. product inflows, waste outflows and emissions, should be allocated to each of the products of these co-production processes. Economic allocation was used for this. Tables 2-4 in Appendix A show the allocation factors.
