The aim of this research was to quantify the amount of waste being generated and to characterize it with type and analyse the efficiency and reality of using reuse and recycling as an answer to the problems of waste management being currently faced in Harare. Northern Harare was chosen as a study area and Environment Africa’s recycling centre was used to for data collection. Collection of data was done from the 1st of August to the 12th of December 2014. The research brought to light the kind of waste and the quantity of waste generated per week in households. To do this, a database was created using Microsoft Excel which contained information of the weight of each type of waste that was brought into the centre. Weighing of waste was done once a week using a heavy duty electric scale. This shade light that households generate paper, soft plastic, PET, HDPE, cans and cardboard. The quantity of waste generated in the five month period was paper=147kg, PET=1053, 1kg HDPE=7957, 1kg, Soft Plastic= 527, 2 kg, cans=3049, 6 kg and cardboard=4840, 7 kg. Also, the amount of each type of waste that was taken by stakeholders from the centre was recorded. To do this, waste was weighed upon request using a heavy duty electric scale and the information was stored in a database created using Microsoft Excel. The amount of waste taken from the centre waste was paper=147kg, PET=957, 3kg, HDPE=7101, 1kg, Soft Plastic=527, 2kg, cans=2000kg, cardboard=3058, 6kg. A two sample t-test was used at 5% significant level for a statistical analysis of these variables. Two –sample t-test, T-calculated = 2.234, D.F. = 5, p > 0.05. This showed that there was no significant difference between weight of waste brought in and weight of waste taken for recycling showing that reuse and recycling has the potential to be an answer to waste management problems in Harare.
