It is technically feasible to produce a medium - quality refused derived fuel (RDF) from the unsorted MSW generated in Maputo (Cidade de Cimento). Although, the final RDF will not be able to meet the calorific requirements needed to be used in the processes by the cement industry in Mozambique.
If the calorific requirements for RDF from the cement producer Cimentos De Mocambique (CdM) were to change to accept medium quality RDF with a calorific value of 15,574 KJ/Kg, the process of Mechanical-biological stabilisation (MBS) or biological drying could be used to produce RDF from unsorted municipal solid waste (MSW). The emission reductions from fossil fuel replacement could range from 4.69 tCO2e/year by the start of the use of RDF, to 4.99 tCO2e/year by 2040. Emissions avoided from landfilling would give higher greenhouse gas (GHG) mitigation results, achieving 22,974 tCO2e/year by 2040. The total avoided emissions would therefore be in the rage of only 5 tCO2e/year the first year, and achieve 22,979 tCO2e/year by 2040.
