Waste disposal is a pressing issue for humanity and has the potential to become a major crisis in the future. One of the best-proposed solutions is to reuse usable materials found in waste, which requires proper waste separation. Experts suggest that separation at the source is crucial, making a functional Reverse Logistics System (RLS) essential. This research aims to provide a structure that can practically redesign the RLS.

Specialists believe that BlockChain Technology (driving force of emerging technologies), has many potential capabilities, which can create many favorable effects in industries. In this research, BlockChain Technology has been used to redesign the RLS with a futuristic approach. That, the mutual collaboration of citizens and the waste collection company is necessary.

A system designed based on this structure is forward-looking and backed by a very effective driving force technology, capable of implementing any policy to increase the separation of waste at source and concluding smart-contracts. It is flexible against sudden increase or decrease in supply without causing audio and visual pollution in traditional systems. Additionally, it is very transparent, safe, and practical. With the proper allocation of the fleet, it can collect all segregated waste.

In this system, with a futuristic approach, waste segregation at the source increases significantly. Resource usage is reduced. The waste disposal problem is being managed. A circular economy is formed. The comfort of citizens increases. The damage to the environment is much less. And action has been taken to transform into smart cities.

The purpose of this research is to identify and rank socio-cultural factors affecting building solid waste management in Tehran. The type of research is analytical which was done using Delphi panel and experts' opinions. In the first step, a list of effective factors was prepared through an in-depth study. Next, this list was provided to the panel and the number of data (KMO=0.688) and its reliability was confirmed (GFI=0.942). Then, by using AHP method, pairwise comparison and final prioritization of factors were done. The results show that Among the 9 factors, pre-university education with a weight of (1.000) has the highest score, followed by social relations (0.609), living place (0.528), individual motivations (0.457), virtual space and Public media (0.280), public education (0.191), university education (0.134), job and social position (0.104) and finally, education level (0.077) were located. Therefore, in order to achieve the goals of sustainable development and optimal management of waste in the metropolis and especially in Tehran, it is necessary to pay attention to the type of factors as well as their priority and delay. Pre-university education is the most effective factor in this field.
