Abstract [en]

Environmental consequences of implementing Uppsala's waste management plan have been analysed using ORWARE, a computerized static substance flow model based on life cycle assessment methodology. Normalizing emissions from waste management to total emission loadings in the municipality was tested as a means to improve the evaluation. It was found that anaerobic digestion of biodegradable waste can reduce net environmental impact, while large-scale composting either increases environmental impact or gives less reduction than anaerobic digestion. In either case, metal contamination of digester sludge or compost may limit the feasibility of the systems. Increased materials recycling has the potential of reducing environmental impact, provided that processing of recycled materials causes equal or less environmental impact than extraction and processing of virgin raw materials. Normalization showed that all impact categories were of roughly equal importance. It was shown that easy accessible data published by a Swedish municipality were sufficient to do a relatively comprehensive normalization.

Abstract [en]

A simulation model, ORWARE (ORganic WAste REsearch), for the handling of organic waste in urban areas has been constructed. The model provides a comprehensive view of the environmental effects, plant nutrient utilisation and energy turnover for this large and complex system. The ORWARE model consists of several sub-models; sewage plant, incineration, landfill, compost, anaerobic digestion, truck transport, transport by sewers, residue transport and spreading of residues on arable land. The model is intended for simulating different scenarios, and the results are: emissions to air and water, energy turnover and the amount of residues returned to arable land. All results are presented, both as the gross figure for the entire system and figures for each process. Throughout the model all physical flows are described by the same variable vector, consisting of 43 substances. This extensive vector facilitates a thorough analysis of the results, but involves some difficulties in acquiring relevant data. In this paper, the model is described. Results from a hypothetical case study are presented in a companion paper.
