ESTIMATION METHOD OF CAPITAL COST • Method developed by R. Turton (1998) and K.D. Kimmerhaus (2002) on the evaluation of the economics (capital costs, operating costs) of chemical process (U.S.A.) and applied once in MSW by D.C. Wilson (1981) CT = CFC + NPCC (non- plant capital costs: start-up, land, working capital) CFC = DPC + IPC (direct plant costs, indirect plant costs) fL or k : Lang factor CFC = fL IEC with IEC: fixed-capital costs of the plant, installed equipment cost - k : fluctuates according to the process and the process type - IEC : updateable with economic indexes
ESTIMATION METHOD OF OPERATING COST Fixed Costs - Labour : L - Insurances - Taxes - Overhead Variable Costs - Energy : E - Other utilities - Reagent : R Maintenance - Equipment : IEC - Civil works : IGC • Method developed by R. Turton (1998) and K.D. Kimmerhaus (2002) on the evaluation of the economics (capital costs, operating costs) of chemical process (U.S.A.) and applied once in MSW by D.C. Wilson (1981) C0 = Direct Costs + Indirect Costs = DC + IC with DC = f(L, E, R, I) and IC = g(I, L) C0 = a . L + b. E + g . R + d . I Each basic variable (L, E, R, I) is estimated by ratio in physical units combined with the standard prices units

APPLICATION TO THE COST ESTIMATION METHOD • CollectionApplication of the cost model to a standard circuit of collection, with performances observed of collection of a given flow of waste • Sorting plant Typology according to design capacity, number of sorting lines, level of mechanization • Composting plantTypology according to the importance of the fermentation equipment • Incineration plantDistinction according to APCS (Air Pollution Control System) : dry, semi-wet and wet srubber • Landfill Distinction with: • - impermeable / semi-impermeable cover • - energy biogas valorization
GENERAL FORMULATION OF CAPITAL COST General formula : CFC = k . IEC • Collection : vehicle, bins : purchased cost • Sorting plant : CFC = k IECR Cn with k & IECR calculated for each type • Composting plant : CFC = k (k1 . Cn + k2) with k, k1 & k2 calculated for each type • Incineration plant : CFC = k1 . Cn + k2 • Landfill : CFC calculation
GENERAL FORMULATION OF OPERATING COST General formula : C0 = a . L + b . E + g . R + M • Collection : C0 = a . L + b . E + M • Sorting plant : C0 = l(a . L + M) • Composting plant : C0 = a . L + b . E + M • Incineration plant : C0 = a . L + b . E + . R + M • Landfill : CFCcalculation • Parameters of the main explanatory variables L : labour E : energy R : reagent M : maintenance • Coefficients representing the secondary expenditure a b g l

PRODUCTION COST DETERMINATION • Gross production cost Cp = CC + C0 = CFC / d + C0with d : life time of the plant Vehicle d = 7 years Sorting plant d = 15 years Composting plant d = 20 years Incineration plant d = 20 - 30 years Landfill d = 20 years • Net production cost • Cpn = Cp - Sr with Sr : revenues by-products sales
Presentation of the Full Cost method • An American bibliography : methodological proposal by the «Environmental Protection Agency» (EPA) : • A working method flexible and adaptable to personalize according to the needs to retrace as close as possible the service cost. • In first step, description phase of material ’s flow identification, • In second step , identification and affectation of financial flows • Accounting of costs rather than expenditures • Accounting of monitoring costs and indirect costs . Accounting according to two approaches : per path, per activity • Distinction of three levels of cost observation : cost by activity or plant (niveau A), cost by stream (niveau B), cost for the local authority (niveau C)
Explicative scheme of the activity and path distinction (b) The horizontal approach per activity (a) The vertical approach per stream Cost/activity all types of wastes Collection activity Collection activity Transport activity Cost/activity all types of wastes Transport activity Cost per type of waste or treatment, all activities melted Transfert-transit activity Cost/activity all types of wastes Transfert-transit activity Treatment activity Cost/activity all types of wastes Treatment activity Valorization activity Cost/activity all types of wastes Valorization activity

LIMITS OF RESULTS OBTAINED • Difficulties to obtain detailed costs in European countries (specially when the private sector builds and exploits) • Diversity of composting processes and limit of validity of composting models up to 60.000 tpy • Costs, availables for the sorting plants, come from the U.S, especially types 3 and 4. • Knowledge of the costs is restricted on energy valorization of biogas in landfill • Production cost models give an estimated cost which can be different of each real case (result of tender offer) • The implementation of the methodology for the providing cost requires to have the whole financial data and a flow sheet of organisation of service
