Abstract [en]

Indonesia’s fast rate of development is causing problems concerned with waste management. Only 25% of the waste, of which 62% consists of organic solid waste, is being collected and mostly brought to open dump sides or more unfavourable places. Although there is a market for inorganic valuable waste, organic solid waste is preserved as invaluable. The aim of this thesis is supporting valorisation of organic solid waste through an economic feasibility study of an organic waste treatment system which uses larvae of the black soldier fly - Hermetia illucens – that feed on the organic waste and can be sold as chicken or fish feed providing an economic incentive for organic solid waste separation and treatment. A time motion study is performed to analyse the labour time used to process one ton of organic solid waste in a black soldier fly rearing and organic solid waste treatment plant at Puspa Agro, a wholesale market in Sidoarjo, Indonesia. The results of the time motion study are combined with the other identified fixed and variable costs. Together with the potential income of the plant, an economic feasibility analysis is performed. Results show that the labour is by far the highest contributor to the total variable cost. The economic feasibility study shows that with the current set-up of the plant, processing organic solid waste with the use of the black soldier fly is not profitable. However, based partly on the preliminary results of this study, a new system has been designed and based on the adjustment of the fixed cost, the alternative system could turn the plant into a profitable business.
