Municipal Solid Waste Composition Analysis Study Juba ... - UNEP

8. At the start of the characterization exercise, waste samples were selected from thestockpiled bagged waste from the SSDO waste generation exercise.9. Once the stockpiled bagged waste was exhausted on Day 4 of the wastecharacterization exercise, waste was obtained randomly from incoming wastecollection vehicles.10. Complete details of the source and type of each waste sample examined areprovided within Table 1 below.11. Information on the sampled waste both from the SSDO exercise and from thedriver of selected waste collection vehicles was obtained and recorded within thewaste sampling form – a copy of which is provided within Attachment 2 of thisreport. The type of information collected for each waste sample included:a. date;b. time;c. vehicle details;d. origin of waste;e. weather conditions.12. For waste samples obtained from incoming vehicles – the site’s wheeled-loaderwas used to mix and cone the waste and transport a sample to the designatedsampling area.13. The waste was placed onto the tarpaulin and a representative 100kg sample sizeobtained using the bench-scale.14. The sorting personnel began sorting the selected waste sample without delay.15. All containers within the waste, such as capped jars, paper bags, and plastic bagswere emptied of their contents and the different materials segregated – such asmetal lids from glass jars.16. Following identification and segregation each waste item was segregated andplaced in the appropriately labeled storage container.17. In the case of composite items found in the waste, the individual materials wereseparated, where practical, and the individual materials placed in the appropriatestorage containers.18. Sorting of the waste continued until the maximum particle size of the remainingwaste particles was approximately 10mm at which point the remaining particleswere apportioned into the storage containers corresponding to the wastecomponents represented in the remaining mixture.19. The gross weights of the storage containers was then recorded on the prescribedform including, where necessary, waste items sorted but not stored in thecontainers.20. Following the weighing of the wastes from the sorting area it was removed eitherby hand or by the wheeled-loader.21. The target was to complete five (5) to six (6) samples each day although due tologistical constraints on the site this did not always prove to be possible.Municipal solid waste composition analysis study – Juba, South Sudan 10
