About this study.

During my end-of-study internship at EDF R&D Chatou (MFEE Department, April to August 2018), supervised by Sébastien Gros and Claude Basdevant, I built a multi-criteria framework to compare energy recovery routes from waste. The study covers waste characterization, a technology panorama, and two case studies: five schemes for metropolitan residual waste, and alternative schemes for two island communities in the French overseas territories, La Nouvelle (60 inhabitants) and Le Cirque de Mafate (700). This is an internship research and consulting deliverable, not a commercial deployment.

Interactive presentation.

Methodology flow with three stages: waste characterization, valorization routes, and EDF case studies, connected by collaborative sharing sessions and exchanges. — Three-part methodology: waste characterization, a valorization-route panorama, then EDF case studies, with sharing sessions and exchanges across MFEE, EIFER and TREE.Adrianto, L.

Table of techno-economic results for five metropolitan schemes, listing electricity and heat output, overall efficiency, CAPEX and OPEX. — Techno-economic results across the five metropolitan schemes: annual electricity (86–205 GWh) and heat output, overall efficiency (0.49–0.57), CAPEX (104–190 M€) and OPEX.Adrianto, L.

Stacked bar chart of treatment cost per tonne of waste for five schemes and three parametric variants, against the landfill and metropolitan incineration cost ranges. — Treatment cost per tonne of waste: 75 €/t for a large 100 MWth incinerator up to 153 €/t for a 10 MWth unit, with TMB-based schemes at 107–117 €/t against the landfill (65–75 €/t) and incineration (75–110 €/t) ranges.Adrianto, L. R. (2018). End-of-study internship final defense, EDF R&D Chatou / École Polytechnique.

Material recoverability chart comparing schemes by share of materials to landfill, transformed recyclables and good-condition recyclables, plus a flow diagram of metals and inert recovery. — Material recoverability: direct incineration schemes send about 12.6% of the input to landfill, while TMB-based schemes recover 87% of metals and inert in good condition and landfilling stays below 10%.Adrianto, L.

Bar chart of greenhouse gas emissions per tonne of waste for the open-burning reference and valorization schemes at different population sizes, split into total, biogenic, avoided fossil and net emissions. — Greenhouse-gas balance per tonne of household waste when energy valorization displaces fuel-oil electricity: the combustion and gasification schemes turn net-negative (−0.29 to −0.38 tCO2 per tonne), unlike the open-burning reference.Adrianto, L.
