The net-zero greenhouse gas (GHG) emissions strategy aims to avoid emissions from all economic sectors by 2050. Although the reduction of GHGs has been considered an urgent issue in all industrial divisions, there are still gaps in climate change mitigation strategies and policies in other sectors, such as waste, accounting for 3–5% of GHG emissions generation which are emitted from landfills, waste transport, waste treatment processes, and incinerators (Clark et al. in Nat Clim Chang 6:360–369, 2016; Masson-Delmotte V, Zhai AP, Connors C P, S. Berger, N. Caud, Y. Chen, L. Goldfarb, M.I. Gomis, M. Huang, K. Leitzell, E. Lonnoy, J.B.R., and Matthews TKM, T. Waterfield, O. Yelekçi, R. Yu, and B. Zhou (eds) (2021) Climate Change 2021: the physical science basis. editor, contribution of working group I to the sixth assessment Report of the Intergovernmental Panel on Climate Change;). Waste management is a worldwide issue related to the circular economy. The share of the waste sector in the UK for GHG emissions generation is 3.7% in 2021, and landfills are responsible for 70% of the emissions (Rogelj et al. in Nat Clim Chang 591:365–368, 2021). Therefore, a new approach to waste management and disposal strategies is crucial. This paper reviews the key elements and challenges involved in waste management systems, specifically in the UK, including policy and legislation, infrastructure, and technological advancements. The review offers a clear summary of the application of circularity waste management strategies, focusing on the UK’s goal to achieve the net-zero target. This review found that to reach the sustainable development goals (SDGs) and 2050 net-zero goals, the existing waste management hierarchy is no longer appropriate for the global and national setting. The metrics in waste management in the context of the circular economy should be aligned with the optimization of using resources, waste minimization, and increasing product life cycle by considering environmental impacts. Therefore, the circular model can be deployed instead of the hierarchy concepts. Graphical abstract
