1. To study and design an innovative municipal solid waste treatment
by handling the MSW through incineration process as a new
alternative method instead of disposal in landfill and make it as
valuable energy resources.

Everyday Bogotá produces around 7,278 Ton of municipal solid
waste (MSW); which consists of organic, plastic, paper and inerts.
A design of an incineration system for Bogotá was presented by
Eternity in this study. It was found that the incineration of the MSW
of three areas in Bogotá suitable for incineration and energy
generation. With a capacity of 30 Ton/h of MSW and a heating
value of 9,6 MJ/kg, 18MW of energy are produced. From the total
energy generated, 8MW estimated for internal consumption and
the remaining 10MW are sold to the grid.
MSW Receiving and Handling
720 Ton /day of MSW with a storage capacity of 8,000 m3
Incineration (1148°C)
2 incineration units fed with 15 Ton of MSW/h per unit
Boiler Heat recovery
Electricity generation capacity of 18 MW
Selective Catalyst Reduction (SCR)
Removal of 1073 kg/h of NOx and
Dioxins and Furans
Electrostatic Precipitator (ESP)
Collection of PM by 99.8% (2µm) and 97% (1µm)
Venturi Scrubber
Acidic gases removal (SOx, HCl) between 70% to 99%
By product Handling
Production of 24.25 kg of Fly Ash / Ton of MSW and
2.15 kg of Bottom Ash / Ton of MSW
Clean GAS
Pollutants below the reference values established by Colombian
Regulation 1377 of 2015

Since November 1988, landfill “Doña Juana”
has been the only solution for the Bogotá’s
MSW disposal. Taking into account the
limitations of the landfill and Bogotá’s target
in MSW reduction; an incineration plant is
proposed in this study. The incineration plant
will reduce 9% of the total MSW generated
in 2016 which has capacity of 30 Ton/h and
covers three areas
