“…As it is shown in [10], in recent years, interest in burning the high-calorific fraction to obtain electricity has arisen in many countries worldwide. The reasons considered by the authors explain the increased interest in waste incineration for energy: depletion of natural resources, increased waste generated lack of landfill space, reduced greenhouse gases emissions, and reduced dependence on imported energy sources.…”

This experimental research was purposed to investigate the production and energy potential of solid recovered fuel (SRF), obtained by extraction of prohibited materials, shredding and drying, from refuse-derived fuel (RDF) to use as an alternative fuel in the cement industry of Lithuania. The characteristics of the obtained RDF by separating the biological fraction from the mainstream of municipal solid waste (MSW) have been determined and compared with the criteria set by developing countries. According to EN15359, currently available RDF can't be called SRF and used as an alternative fuel in a cement kiln. The SRF production line by adding six additional technological units to the existing MBT line was developed. The calculation of the SRF production line was carried out and made 1.89 t/h. At the end of the production process of SRF from RDF, the moisture content (MC) of the obtained SRF decreased by 90 %. After the drying stage, the volume of SRF decreased by 19 %. The process of preparing SRF allowed increasing the net calorific value (NCV) by 22.1 % to 28.2 MJ/kg by reducing the MC. The obtained SRF had a high NCV, low MC, permissible Cl and Hg contents. Two scenarios of waste generation in the Alytus region until 2030 have been developed. Based on the waste generation scenarios results, the proposed SRF production line will provide 12 % of the additional fuel for clinker firing during the analyzed period. A cost analysis to assess the economic and environmental savings from the use of SRF was performed. The results showed that adding 12 % of SRF as a replacement fuel, equal to 1.86 t/h, to the coal used in the cement kiln would save 860 USD/h in coal costs. At the same time, it will emit 5.96 t/h of CO2 into the atmosphere, and the net savings will amount to 1,131 USD/h.

“…Considering construction material based on red mud, this material has been investigated on special cement production [104][105][106][107][108]. Using wastes or secondary raw materials in construction is essential to face the diminution of primary raw materials and promote the circular economy [109]. This application is fundamental since it desires huge material volume.…”

Red Mud from the Aluminium Industry: Production, Characteristics, and Alternative Applications in Construction Materials—A Review

et al. 2021

About 120 million tons of red mud is produced worldwide each year. Due to its high basicity and potential leaching, its storage is a critical environmental problem. This material is typically stored in dams, which demands prior care of the disposal area and includes monitoring and maintenance throughout its useful life. Consequently, it is crucial to figure out an industrial solution able to consumes large volumes of this material. At this moment, there are several studies, the majority in metallurgical procedures, building materials, and in the chemical industry, discussing how to reuse red mud. This paper provides a review of the aluminium process, including metal importance, its global production, and the environmental impact due to its manufacture process. It presents a review of the potential application of red mud showing its overall generation, some relevant characterisation results collected from the literature, and its utilisation in diverse areas of engineering. The study aimed to highlight applications where red mud characteristics may be favourable.

“…This approach follows the EU Action Plan of the Circular Economy which focuses on keeping values of raw materials within the economy for as long as possible and, of course, with the minimalization of the produced waste (Hagelüken, 2016). A complex research oriented on food waste reuse can be identified in the past few years (Arina & Bendere, 2018, Bhargava, 2020, Zhao et al, 2021. However, there is an emerging trend in the research focused on the use of waste created within the food processing industry (Yusoff, 2006).…”

Distilleries for home fruit growers play an important role in the Slovak spirits industry. They represent from 5% to 15% of the total spirits production in the country. In this paper, businesses with a focus on waste management and its future potential were investigated. The investigated industry creates a significant amount of bio-waste when under 10% of raw materials used for the distillation process are transformed into the final product. The waste production in distilleries for home fruit growers based on the available annual production data was estimated in this research. Based on these estimations, distilleries for home fruit growers produce annually 37,407.07 tons of bio-waste on average. The median distillery produces annually around 211.4 tons of bio-waste. The bio-waste from investigated distilleries is used directly as fertilizer on the arable soil at this time. This option is the cheapest solution for distilleries for home fruit growers. The different reuse options for bio-waste from distilleries were compared. All of them were more expensive compared to direct use of bio-waste as a fertilizer. Due to the higher cost, there is no interest to reuse this significant amount of the bio-waste produced in small distilleries for home fruit growers at this moment.
