The nine (9) major waste categories for the characterization exercise were as follows:• Paper and Paperboard• Glass• Metal• Plastic• Textiles• Organics• Construction and Demolition (C & D) Wastes• Special Care Wastes• Other WastesEach waste sample of approximately 100 kg was sorted manually into dedicatedcontainers for each of the respective waste components by a team of 10 local staff whohad been trained by the consultant prior to the exercise. Each of the local staff was veryfamiliar with the site and the handling of waste as they were all informally employed atthe site as waste-pickers.2.2 Bulk DensityThe bulk density of the incoming waste was calculated by executing the followingprocedures:• A container of a known volume (V1) was weighed and its weight recorded (W1).• A sample of each consignment of waste was poured into the container until itoverflowed.• The contents of the container were settled by dropping it three times onto themeasuring table from an approximate height of 10cm.• The container was then topped up with additional waste from the selected sample.• The container was then weighed again and the weigh recorded (W2).• The bulk density was then calculated using the following equation: W2–W1/ V1.2.3 Waste GenerationThis phase of the study sought to determine the waste generation rate per capita for thetown of Juba and was undertaken by the South Sudan Development Organisation (SSDO)- a local NGO - between12-16 December, 2012.SSDO selected 306 houses in total from three different districts of the city to representhigh, middle and low income categories of housing. Additionally, 50 shops of small,medium and large sizes were also selected from the largest market within Juba known asKonyo Konyo Market.Municipal solid waste composition analysis study – Juba, South Sudan 6
Six individuals were recruited as data-collectors – each of whom managed the collectionof data from 60 houses while one data-collector was dedicated to the collection of datafrom shops.The main procedures for the waste generation exercise included the following steps:• Provision of colour coded plastic bags to selected houses and shops:o Yellow for high-income areas and large shops;o Blue bags for middle-income areas and medium size shops;o Black bags for low-income areas and small size shops.• Households were asked to store all waste produced in the preceding 24 hours;• The designated data collector collected and weighed the waste each day using asmall portable weighing machine.• Additionally, the details regarding the number of inhabitants within eachparticipating property were recorded for last 24-hour period.The above procedures allowed for calculation of waste produced per capita byhouseholds in different districts of the town as well as per economic status.Municipal solid waste composition analysis study – Juba, South Sudan 7
