Technology of Combustible Waste Sorting
and RDF Manufacturing Facilities in
Sudokwon Landfill
EXECUTIVE SUMMARY
The household waste carried into Sudokwon (Metropolitan area in South Korea) landfill
site is composed with 94% combustible and 6% incombustible. Eco-friendly mechanical
pre-treatment of waste and RDF (Refuse Derived Fuel) manufacturing plant (200ton/day)
is installed for making energy from combustible household waste. As the percentage of the
water content of actual intake waste is exceed the deign standard, the system had been
overloaded. The trouble has been solved by the addition of air mixing facility and the
renovation of the combustion chamber.
INTRODUCTION
As the paradigm of Korean national waste management policy has been changed from
reduction, reuse and safe disposal into resource circulation ‘Zero Waste’ society,
Sudokwon Landfill Site Management Cooperation (SLC) started the RDF manufacturing
project for minimizing the amount of reclamation and maximizing resource reuse, getting
out of simple reclamation. For treating whole amount of municipal waste carried into
Sudokwon landfill site, SLC have a plan to construct a RDF manufacturing 2,200ton/day
scale plant until 2014. Prior to install the plant, the demonstration plant has been built from
November 2007 to April 2010 included 8months test operation. This study shows the
problems and improvements during test operation.
