“…Compared to studies from other nations, even though it can be seen in Poland that the organic OFMSW fraction is almost twice as large as in Hungary, the plastic fraction >4 cm in diameter is approximately 10-40% depending on the season similar to in Hungary [17]- [18]. Another similar study in the vicinity of Taipei in Taiwan shows that food waste is responsible for 34% of OFMSW in total like in the areas investigated by us, while only 17% of consists of plastic which is lower than the average in Hungary (~25-30%).…”

Municipal solid waste management is crucial in terms of the environment, sustainability and the circular economy. The directly landfilled organic fraction of municipal solid waste (OFMSW) offers a lot of potential with regard to energy recovery or as a soil substrate. In this study, the regional differences in Hungary according to various living structures and conditions (villages and urban areas) were demonstrated to provide a foundation for further usage or treatment. The fact that the biological fraction (leaves, kitchen waste and fine soil-like material) of OFMSW from typically urban areas like the examined city of Pécs is larger than in a rural area, e.g. Marcali District, was highlighted. On the other hand, the OFMSW from rural areas contains more hazardous materials such as medicinal ampoules due to the lack of possibilities to dispose of them suitably. After evaluating the composition of the OFMSW, the directly landfilled quantity of MSW could be further reduced. In conclusion, according to the high proportions of plastic and paper as well as its promising heating value, the largest particle size fraction (>4 cm) could be utilized as refuse-derived fuel (RDF) and the finer, organic material-rich fraction as a soil substitute following further purification.

“…After 1 week, this value was reduced to 9.64% and according to the statistical analysis of the data obtained, the results did not show statistically significant differences until the end of the process (Figure 3, Table 2). The OF content of MMWSF depends on the percentage of individual size fractions (>60 mm, 60-40 mm, 40-10 mm and < 10 mm) [14]. Residual municipal waste is a very heterogeneous material.…”

Poland's mixed municipal waste management system has been based on mechanical-biological treatment (MBT). One of the MBT processes is the biological stabilisation of fractions of less than 80 mm. The final product after biological stabilisation is a stabiliser that, once the conditions required by law are met, can be landfilled. The stabilizer must meet the following requirements: the loss of ignition (LOI) of the stabiliser is less than 35% DM, the organic carbon content is less than 20% DM and the AT4 value (aerobic 4-day respiration test) value is less than 10 mgO2/g DM. The study aimed to analyse the changes that occurred during the first 4 weeks of biological processing of the fraction of less than 80 mm of mixed municipal waste. The bioreactor feedstock consisted of 41.7% organic fraction (OF), the LOI was 32.3%, and the AT4 value was 45.7 mgO2/g DM. During biological processing, at 4 weeks, the loss of OF in the total weight of the waste was found to be 22.6%, the losses after roasting decreased by almost 90% and the value of AT4 was 6.6 mgO2/g DM. This means that the stabiliser already after 4 weeks, according to the law, could be sent to a landfill.

“…Utilizing composting is an appropriate approach for recycling GW as the resulting compost serves as a valuable organic amendment and/or substrate that be reintegrated into the economic cycle effectively [21]. Composting organic waste involves the utilization of aerobic microorganisms to transform waste materials into compost, which serves as a valuable resource for soil enhancement [22,23].…”

This study seeks to develop effective solutions and strategies for waste management in the Tunisian municipality of Bizerte by addressing the urgent need for sustainable waste management practices in light of the global imperative to mitigate climate change. With a specific focus on reducing greenhouse gas emissions, this investigation aligns with Tunisia’s commitment to international agreements, including the Paris Agreement and the Global Methane Pledge. This study begins with an exploration of background information, followed by data collection and waste characterization to determine the current situation and to detect gaps that exist in terms of waste management in Bizerte municipality. Two scenarios are proposed as potential solutions for the municipality. The first examines a green waste composting facility with a 1000-ton yearly capacity, which has been operational since 2020. This study describes the compost production process and evaluates the quality of compost derived from green waste. This approach demonstrates its potential for delivering significant environmental and economic benefits. The second scenario delves into the implementation of a mechanical biological treatment (MBT) plant for sustainable handling of residual waste while contributing to a reduction in the municipality’s overall environmental footprint. Using the Sweet software, version 4.0.2, July 2022. this study quantifies the potential reduction in greenhouse gas emissions resulting from composting to be 3%, while the MBT achieves a reduction of 28%.
