Purpose The target date to achieve the Sustainable Development Goals (SDGs) by 2030 is less than a decade; urban commercial solid waste in developing nations has elicited considerable concern. From previous studies, some policies on commercial refuse have been implemented, but the issue persists. The purpose of this study is to examine Sustainable Human Settlement (SHS) using Commercial Solid Waste (CSW) disposal systems to achieve SDG 11. Design/methodology/approach This study engaged a multistage sampling technique to examine the types, quantities and impediments of CSW disposal practices. The market and three trades with the highest volume of refuse were selected via purposive sampling at the first and second stages, and random sampling at the third stage to identify the 15 lines that generated the most trash. A questionnaire was administered to 345 traders using systematic random sampling, and the data were analysed using inferential statistics. The diffusion of innovation theory (DoIT) and theory of planned behaviour (ToPB) constructs applied confirmed the theoretical gap. Findings The findings revealed that decomposable (84.85%) and non-decomposable (15.15%) refuse were generated daily (2,611.07 kg), weekly (13,055.35 kg) and 339,439.1 kg in the dry season. Tailoring materials generated the highest daily refuse (1,162.80 kg). Inadequate skips, poor funding, insufficient decision-making process, poor maintenance of facilities and scarce technical measures were identified as impediments to the CSW disposal system at the marketplace. DoIT and ToPB can be applied to enhance CSW disposal practices for SHS. Audit policy will help achieve SDG 11 across marketplaces in Nigeria. Originality/value As part of this study’s implications, DoIT and ToPB will be used to improve SHS through the CSW disposal system at the Ahia-Ohuru market.
