“…Direct combustion is also not feasible due to the presence of heavy metals (mainly chromium (III) and chromium (VI), cadmium, copper, mercury and lead) [20,29,30], although methods are being developed for combustion under strictly controlled conditions using emission reduction devices. A study by Wei Ding et al [30] presented the development of methods to reduce the presence of heavy metals.…”

The tanning industry generates significant amounts of solid waste and post-production wastewater, which should be managed in accordance with the principles of the circular economy. Waste is generated at various technological stages of production. This comprises mainly solid waste and leachate. A comprehensive solution to the problem of disposal of this waste is very important from economic and environmental points of view. This work presents research for a technological production line designed for the comprehensive processing of post-production residues. In the present paper, the authors present an analysis related to the possibility of processing leather flesh side (mizdra) as a substrate for methane fermentation. The study showed an increased biogas production from solid waste after enzymatic hydrolysis up to 248 Nm3/Mg. Preliminary research on the system designed for pre-treatment of sewage from the technological line is also presented. The study showed a COD reduction of more than 30%. The possibility of energy management of the solid fraction directly from the processes carried out is demonstrated.

“…Solid wastes can be easily converted into heat or fuel/oil using 'Waste to Energy' technologies, especially thermal processing techniques. Thermal "Waste to Energy" technologies, also known as incineration, are a widely used method for managing solid waste (Muralidharan et al 2022;Shah et al 2022). The process involves burning solid waste at high temperatures to generate heat and electricity.…”

One of the pressing issues any country faces is managing solid wastes. Traditionally, several methods have been used in the past to manage the increasing quantity of solid waste. However, due to the increase in population, urbanization, and various other reasons, there has been steady growth in solid waste. The general public's cooperation is vital in understanding the extent of solid wastes, their generation, collection, transportation, and disposal of wastes safely. Urban local bodies also play a significant role in managing waste as they are the ones who can formulate a plan as per the data available to them. Infrastructure for managing solid wastes is another prime factor in easy transportation and disposal. There are different conventional methods starting from landfills, incineration, etc., to advanced methodologies. The use of incineration as the primary method of waste disposal is now a major source of health hazards. The present study reviews the important practical methods for solid waste management. The review is categorized into two sections: Conventional methodologies include incineration, thermal to waste energy techniques, bioeconomy, anaerobic digestion and waste valorization and the second section includes advanced methods such as green architecture, web-based geographic interface system, Internet of Things (IoT), optimization techniques, artificial intelligence and blockchain based solid waste management system. The present study also provides an overview of the advanced technologies as a support system for the sustainable management in solid waste. It also discusses the knowledge and awareness to be catered to all sections of people about sustainable solid waste management.

“…Kulit adalah produk hasil daur ulang dari limbah padat industri daging. Sektor kulit merupakan salah satu industri terkemuka yang memegang nilai perdagangan global sebesar USD 394,12 miliar pada tahun 2020 dan diperkirakan akan tumbuh pada tingkat pertumbuhan tahunan gabungan (CAGR) sebesar 5,9% dari tahun 2021 hingga 2028 dengan perkiraan nilai perdagangan sebesar USD 624,08 miliar pada 2028 [2]. Produksi kulit global tahunan diperkirakan mencapai 23 miliar persegi feet di mana sektor alas kaki kulit mendominasi pasar dengan pangsa 65% dan jenis produk kulit lainnya sebesar 35% [3].…”

Rapid globalization has led to the growth of a significant amount of waste, including in the industry. Due to the considerable amount of growth of waste every year, effective and efficient waste management is needed to protect our environment. In the leather product industry, waste management is strongly important since it may have a significant impact to the employee and production process. Regarding those issues, waste management technology is considered proposed in order to solve those problems. Current research reported the outstanding work of implementing artificial intelligence for detecting and recognizing industrial waste. Artificial intelligence was proven to be a highly recommended approach that is able to classify several waste types with outstanding performance. Regardless of those facts, artificial intelligence still remains several hurdles, such as the high computational demands, especially for deep learning networks. Regarding the mentioned issue, we proposed a more proper deep learning network for recognizing industrial waste. In this research work, we use Single Shot Detector (SSD) to recognize and classify industrial waste. Our proposed solution was performed in the TrashNet dataset and Waste Picture dataset. Our proposed solution successfully achieve mAP of 0.8813, accuracy of 0,9795, precision of 0,9985 and recall of 0,9693 in the training process. Whereas, in the testing process we achieve average accuracy of 0,8254. According to those results, we can conclude that our proposed solution is suitable for industrial waste detection and has potential to be implemented as an embedded system for recognizing industrial waste automatically.
