“…From surveys with recyclers, the authors also concluded that recyclers need to develop better solutions in the phase of dismantling devices to improve the recovery performance of valuable materials. The same is claimed by Bruch et al (2021) through interviews with recyclers. New solutions to sorting materials and other pre-extractive techniques lack research (only 10.8%, as aforementioned).…”

After more than a decade since smartphones became consolidated in the market, many recycling solutions have been proposed to deal with them. To continue developing useful solutions and enable adjustment of routes, this mini-review aims to analyse the current research scenario, presenting relevant gaps, trends and opportunities. From a structured searching and screening procedure, a vast source of data was arranged and is available to extract useful information (43 studies on composition and 93 studies on recycling). The study provides discussions about the history of smartphone development, constituent materials and recycling methods for different components, comparisons between feature phones and smartphones and others. Among some conclusions, the authors highlight the lack of studies on pre-extractive methods, green chemistry, recovery of critical and precious metals, determination of priority materials for recovery and solutions for entire devices. In the end, a list containing six research gaps for composition studies and seven research gaps for recycling studies is provided and may be seen as opportunities for future research.

Sensor-based sorting describes a family of systems that enable the removal of individual objects from a material stream. The technology is widely used in various industries such as agriculture, food, mining, and recycling. Examples of sorting tasks include the removal of fungus-infested grains, the enrichment of copper content in copper mining or the sorting of plastic waste according to the type of plastic. Sorting decisions are made based on information acquired by one or more sensors. A particular strength of the technology is the flexibility in sorting decisions, which is achieved by using various sensors and programming the data analysis. However, a comprehensive understanding of the process is necessary for the development of new sorting systems that can address previously unresolved tasks. This survey is aimed at innovative researchers and practitioners who are unfamiliar with sensor-based sorting or have only encountered certain aspects of the overall process. The references provided serve as starting points for further exploration of specific topics.

The relevance of the topic lies in the fact that the level of competitiveness of a bank in waste management will have an increasing impact on its ESG ratings in the future. The purpose of this paper is to improve waste management in a bank (mainly faulty office equipment and paper waste). However, not all banks use active management methods in waste management, so this article offers recommendations for the successful management of key indicators. The article uses data on waste from banks in Bangladesh, China, Indonesia, Kuwait, India, Malaysia, Nepal, Pakistan, Sri Lanka, the UAE, and Vietnam. The objectives of the study include: identification of the essence of the competitiveness of waste management in a bank; consideration of the types of competitiveness of waste management; assessment of the impact of blockchain technology on the competitiveness of waste management; assessment of minimizing waste management costs in a bank. A method for waste composition and waste export based on statistical analysis and a regression model. It used data about the current waste management activities of a bank. This study uses data from an annual time series covering the period from 2013 to 2021. The results of the study confirm that the problem of electronic waste of banks in Asia can be solved by increasing financing and a complete analysis of bank waste. There are points of novelty in the article: (1) the essence of the competitiveness of waste management in a bank is determined, which consists in the recycling of most waste and not in their disposal; (2) the ideas of the competitiveness of waste management are considered in Sberbank; (3) the impact of blockchain technology on the competitiveness of waste management in banks is assessed; (4) an assessment of the competitiveness of waste management in a commercial bank is given. In order to better understand the factors influencing the production of e-waste in the region, the study focuses on the significance of addressing the rising problem of e-waste in Asia and the need for better collection and analysis of waste data in a bank. The main conclusion is the need to recycle waste and increase recycling costs in the future, which is the most environmentally friendly option compared to incineration.
