The current waste management systems are struggling to optimally handle biodegradable plastics (BDPs) and facing numerous challenges; one of which is the consumer confusion about how best source-segregate BDPs. Based on an environmental life-cycle assessment, this study investigated consequences collecting BDPs in three streams (packaging waste, biowaste, residual waste) Austria. Collecting as (i) packaging resulted incineration (SP1) or mechanical recycling (SP2), (ii) biowaste composting (SB1) anaerobic digestion (AD) (SB2), (iii) (SR1). SP2 performed most 16 impact categories (ICs). Three scenario analyses demonstrated that utilisation alternative fuel for process heat substitution yielded more benefits than SP1 SP2, adding a material recovery facility (MRF) with AD increased load SB2, while energy zero electricity imports plus from biomass pathways across ICs. Eight technology parameters (out 97) were identified relevant results based data quality, sensitivity ratio, analytical uncertainty; they related incineration, MRF, facility, compost- processes. Overall, emerged favourable option aligned waste-hierarchy mentioned European Union Waste Framework Directive. However, effective requires 'sufficient' amount, market recyclates, infrastructure.
